Funding the account is where most newcomers to prediction markets stumble — not because it is complicated, but because one small field called "network" decides whether your money arrives in minutes or is gone forever. At PolySouq, funding happens in real USDC on the Polygon network only, through a personal deposit address that belongs to you, with a 0 minimum. There is no wallet connection, no bank deposit and no demo account. This guide walks you step by step through how to obtain USDC, why the network must be Polygon and not Ethereum, BNB or Arbitrum, what gas and the POL token actually mean, and then works through the most common USDC deposit problems in practical tables: the deposit that never shows, the wrong token, the address copied one character short, and how to execute an emergency withdrawal on Polygon correctly. The golden rule everything below rests on: always test with a small amount first, because on-chain transfers are final and cannot be undone.
When you send USDC from your wallet or from an exchange to PolySouq, you are not making a bank transfer that a staff member can halt or reverse. You are broadcasting a transaction on a public blockchain, and that transaction is final the moment it confirms. That is why the most important field on the withdrawal screen is neither the amount nor the address — it is the network. A wallet address on the Polygon network looks exactly like an address on Ethereum, Arbitrum or BNB Smart Chain — the same shape, starting with 0x and running 42 characters — yet assets that arrive over a different network never appear in your balance, because the smart contract that represents the token differs from chain to chain.
This visual sameness is the number-one cause of "I sent the money and it never arrived" reports. The user genuinely copies the correct address, then picks a different network from the dropdown — usually whatever their exchange defaults to — and the transaction is recorded on a chain the system does not monitor at all. There is no visible error and no rejection message; the transfer succeeds technically and fails practically. That is why every serious deposit page repeats a bold warning about the network rather than about the amount.
At PolySouq the rule is single and admits no exceptions: USDC on the Polygon network only. Not Ethereum mainnet, not BNB Smart Chain, not Arbitrum, not Optimism, not Solana, not Tron. And if you want the full financial picture before you deposit your first dollar — where fees come from and how they are calculated — start with deposits, withdrawals and fees, then come back here for the practical execution.
One last point deserves emphasis before any step at all: sending assets on the wrong network is generally unrecoverable. No platform can "return" a transaction executed on another chain, and you should not believe anyone who promises to do so for a fee — that is an extremely common scam pattern. The only effective protection is preventive: verify the network, then test with a small amount.
Step zero is not the deposit itself — it is actually holding USDC on the Polygon network. You have two practical routes. The first: buy USDC on a crypto exchange that supports Polygon withdrawals, then withdraw it directly to your personal deposit address at PolySouq. This is the simplest and least error-prone route, because the exchange covers the network fee on your behalf and you never have to manage a gas balance in your own wallet.
The second route: hold USDC in a self-custody wallet that supports Polygon and send from there. This gives you more control but imposes two responsibilities on you — making sure your balance actually sits on Polygon and not on another chain, and keeping a small balance of the POL token to pay gas fees. Without POL, your wallet cannot send anything at all, even if your USDC balance runs into the thousands; the transaction simply will not broadcast.
There is a third route some traders use: bridging from one network to another. We do not recommend it for beginners. Bridges add a layer of complexity and delay, and some of them produce a "bridged" version of the token under a different symbol — which is precisely the source of the confusion between native USDC and USDC.e that we unpack in a later section. If you must use a bridge, verify the resulting contract address before sending anything to a platform.
Whichever route you take, keep in mind that all of this precedes trading and is not part of it. If you are still working out how the mechanism itself operates, read how prediction markets work first, then fund the account with a test amount — funding an account you will not use straight away is risk with no return.
Account creation is free at PolySouq: no subscription fee and no opening balance. Once the account exists, you receive a personal deposit address on the Polygon network. That address is tied to your account specifically — it is not a shared public address; any USDC that reaches it on the correct network is credited to your balance automatically once confirmations complete. There is no "connect your wallet" button in this model and no MetaMask or WalletConnect popup — you simply send the funds to your address.
The practical sequence is as follows, and we recommend following it literally the first time:
Pay particular attention to the minimum, because it is a recurring cause of "my deposit never showed" reports. The minimum deposit is 0, and amounts below that may not be credited. So "testing with one dollar" is not a valid test here — the correct test is an amount that clears the minimum by a modest margin, such as
Once the balance appears, you are ready to move on to execution. If this is your first time, it helps to walk through opening an account and placing your first trade, then browse what is live on the markets page and pick a market whose subject you genuinely understand, whether that is the TASI index or oil prices.
The table below is the reference worth checking before every single send, especially the first few times. The short version: USDC + Polygon = correct, and every other combination means, at best, delay and manual intervention, and at worst a permanent loss of the funds.
Note that the most dangerous row is not the first of the errors but the second-to-last: USDC.e. It carries almost the same name and often shows up in the very same asset list, yet it is a different smart contract produced by bridging from Ethereum. If your wallet displays both tokens, the safe assumption is that the supported one is native USDC on Polygon, and that anything else needs confirmation before you send.
This table may look excessively detailed, but experience with any platform running a deposit-address model says that more than half of all funding problems trace back to a single one of these rows. Five seconds of checking saves weeks of fruitless follow-up — or a total, unrecoverable loss.
Every transaction on the Polygon network requires a network fee paid in POL (formerly named MATIC). That fee does not go to PolySouq or to any platform; it pays for executing the transaction on the chain itself. Polygon's advantage here is obvious next to Ethereum: fees are typically fractions of a cent and block times are short, which makes it a sensible network for the small amounts a day-to-day event trader works with.
Who pays that fee depends on where you send from. If you are withdrawing from a centralised exchange, the exchange handles gas and either deducts its own withdrawal fee from the amount or adds it on top; you do not need POL at all in that case. If you are sending from a self-custody wallet, you pay, and the wallet must hold a POL balance, however small. A missing POL balance is a common silent cause of failed sends: the wallet greys out the send button or rejects the transaction with an insufficient-gas message.
Here is a detail many people miss: you do not need POL in order to receive funds. When you withdraw from PolySouq to your address, the USDC arrives without you paying anything out of your wallet. But you will need POL later, when you want to move those funds from your wallet somewhere else. It is therefore wise to always keep a small POL balance in the wallet you receive into — otherwise you end up holding a balance you cannot move.
Finally, do not confuse network fees with the platform's commission. PolySouq's commission is fixed at 10% and is taken from the losing side of the pool only at settlement — meaning the platform earns only out of realised profits, and this commission is charged on neither your deposit nor your withdrawal. The full detail of that distinction lives on the fees, deposits and withdrawals page.
On the Polygon network, blocks are produced within seconds, which means your transaction lands on the chain very quickly. But appearing in your PolySouq balance requires a sufficient number of confirmations on top of the block that carried your transaction — a standard security precaution at every platform, guarding against transactions that could be undone if the chain reorganises. The practical upshot: a deposit usually appears within minutes — not seconds, not hours.
The real delay is usually not on the chain at all but before it. When you withdraw from a centralised exchange, the withdrawal first passes through internal review and processing queues that can take anywhere from minutes to hours, and sometimes requires an email confirmation or a verification code. During that window there is no on-chain transaction at all, and you will find no trace of it in a block explorer. The right move here is to check the withdrawal status at your exchange, not your balance at PolySouq.
The table below sets out the three states, what each one means, and where to look:
The practical rule: give it a reasonable window before you assume something is wrong. If the window passes and nothing appears, do not resend and do not send another amount "just to test" — diagnose first using the table in the next section, because repeating the send with the same wrong settings simply doubles the loss.
This is the section most readers come for. The correct diagnostic method is to work from the most common cause down to the least, leaning on evidence from a block explorer rather than on guesswork. Every transaction on the Polygon network has a unique transaction hash (TxHash); that hash is your only credible evidence, and it is what you should have in hand before any enquiry.
We should be blunt about one point that does not admit softening: sending on the wrong network is generally unrecoverable. No platform has the ability to reverse a transaction executed on another chain, and nobody should promise you otherwise. Any account or "recovery service" that asks for an upfront fee, or for your wallet's recovery phrase, in exchange for returning the funds is a scam with near-certainty. This loss is entirely preventable, which is why we keep repeating it: test with a small amount.
What you should actually do when in doubt: keep the transaction hash, plus a screenshot of its detail in the block explorer showing the network, the token, the recipient address, the amount and the timestamp. That information reduces any review to minutes, whereas a description along the lines of "I sent it yesterday and it never arrived" is impossible to act on. And if you want to understand how operations and settlements are documented on the platform generally, see how PolySouq settles markets transparently.
The second most common error after the network is the token. The names look alike, the icons look alike, and all of them trade at roughly one dollar — but the contracts differ, and the system reads the contract, not the name. The table below breaks down the three distinctions that matter in practice:
Address errors are rarer but hit harder. Three patterns recur: an incomplete copy that drops a character or two from the end; a paste carrying a space or a newline, which the wallet then rejects; and the most dangerous of all, malware that watches the clipboard and swaps the copied address for an attacker's address matching it in the first and last four characters. That third pattern is the single good reason for a habit that should become a reflex: visually compare the start and end of the address on the final confirmation screen, immediately after pasting and before pressing send.
Another useful habit: save the deposit address in your wallet's or exchange's address book under a clear label once the first test transfer succeeds. That removes the need to copy and paste every time and shrinks the error surface to nearly zero on subsequent transfers. And remember that the personal deposit address belongs to your account; do not share it on the assumption that it is "the platform's address", and never use someone else's address.
Equally important: do not send third-party funds into your account. Funding should come from a source you own. This is not a procedural nicety but sound practice that protects you from needless disputes over ownership of the money, and it is a general principle that applies to any serious trading account.
Plenty of people search for "how to make an emergency withdrawal on Polygon", so it is worth being precise about what that means here. At PolySouq, withdrawal is one simple operation: USDC only, to a Polygon address that you supply. There is no bank withdrawal, no IBAN, no transfer to a card, and no fiat currency at any point. An "emergency withdrawal" is therefore not a special button or an exceptional mechanism — it is simply executing the ordinary withdrawal quickly and correctly the first time.
The fundamental constraint you need to absorb before you need it: you can only withdraw your available balance. Amounts committed to an open market are not available balance, and you cannot exit them mid-event — positions run to settlement. The one known exception is cancelling a football stake before kick-off, which returns the amount in full. Once an event is under way there is no position sale, no early exit and no stop-loss. So if there is a real chance you will need the money within days, the right decision is taken before you enter a market, not after.
In practice, the steps for a fast, safe withdrawal:
For the detailed steps with screens, see the step-by-step USDC withdrawal guide, and for timing and fees see deposits, withdrawals and fees. The decisive point, which we repeat because it is always forgotten: address validation checks the format, not the ownership — a perfectly valid address can belong to someone else, and sending to it is final.
Everything above compresses into one habit that protects you more than all the warnings combined: test the path with a small amount before you send a large one. It does not matter how many times you have sent before, or how confident you are; what matters is that every new path — a new wallet, a new exchange, a new address — is an untested path, and the test costs a few cents in network fees in exchange for securing your entire capital.
The application is simple: your first transfer to PolySouq should be an amount slightly above the 0 minimum. You wait for it to appear in your balance. Only then have you proved that four things are simultaneously correct: the address, the network, the token, and the behaviour of the sending platform. Those are precisely the four elements behind nearly every funding problem there is. The same applies to withdrawals: your first transfer to a new receiving address should be a test.
This rule belongs, at its core, to risk management rather than to anything technical. A trader who concentrates one hundred percent of their capital into a single untested transfer is making the same mistake as one who puts their entire balance into a single market. The principle is identical: do not expose what you cannot afford to lose to a risk you have not verified. If you want a systematic framework for that, read risk and capital management.
Add a third small habit alongside it: do not fund the account until you are actually ready to trade. An idle balance generates nothing, yet it stays exposed to hasty decisions in a moment of enthusiasm. Fund what you need for the markets you have genuinely analysed, and keep the rest off the platform.
Understanding what happens to the money after the deposit makes funding decisions much clearer. PolySouq is not a broker you trade against, and not a market maker taking the other side of your position. The model is a parimutuel pool: everyone backing a given outcome puts their money into one shared pot, and at settlement the holders of the correct outcome split that pot pro-rata by each person's own stake. No house profits from your loss, and no price moves against you at an intermediary's discretion.
The formula is explicit and verifiable: payout = your stake × (1 + losing side total ÷ winning side total × (1 − commission)), with the 10% commission taken from the losing pot only. Your original stake comes back to you in full on top of the profit share. Several logical consequences follow. If nobody is on the other side, everyone gets their money back and the commission is zero. If nobody backed the winning outcome, the market is voided, all stakes are returned, and the commission is again zero. And in every case the system asserts that total payouts plus commission equal exactly the total staked into the market.
That is why we do not describe our activity as betting. There is no counterparty that benefits from your loss, and no odds set by a bookmaker in its own favour. Prediction markets are an information-aggregation mechanism: an outcome's implied price reflects how money is distributed across the outcomes, and it moves as new information arrives. If you want to go deeper on that side, read reading prices and probabilities, and for the Islamic-finance angle specifically there is is prediction market trading halal?
And let us be clear about the risk: this is real money, and losing the full amount you commit is possible. There are no guaranteed profits, no demo account, no virtual coins and no signup bonus. Only fund your account with an amount you can afford to lose without it affecting your financial position. What we provide here is general educational content and does not constitute individual investment advice.
Many funding problems come from expectations imported from other platforms. So it is more useful to say plainly what does not exist here, because knowing the boundaries spares you failed attempts and time wasted hunting for a feature that was never there:
This list bears directly on the funding decision. The absence of an early exit means the size of the amount you commit must be settled before you enter, not after. The absence of bank withdrawal means your cash-out plan has to be ready in advance: a USDC on Polygon receiving address you control, an off-ramp into your local currency if you need one, and a realistic sense of how long that whole chain takes.
By contrast, the absence of leverage and margin is a feature, not a shortcoming. The most you can lose is the amount you committed to a given market — no margin calls, no forced liquidation, no debt on your account. That makes the risk calculation simple and direct, and it is what distinguishes event trading from a great many leveraged trading instruments.
Once the whole picture is in place — where the money comes from, how it goes in, where it is held, and how it comes out — funding becomes routine rather than a source of anxiety. Start small, get every step right once, and then move on to what actually matters: analysing the markets themselves, whether that is interest-rate decisions, OPEC meetings or sports markets.
The minimum deposit is
The funds will not appear in your balance, because the system monitors the Polygon network only. The transaction succeeds technically on whichever network you chose, but it lands on a completely different chain. And we will be direct with you: this kind of error is generally unrecoverable, and no platform can reverse a transaction executed on another chain. Be wary too of anyone offering to "recover" your funds in exchange for an upfront fee or for your wallet's recovery phrase — that is a common scam pattern. The only effective protection is preventive: verify the network before sending, and always test with a small amount.
Start with a structured diagnosis. If you have no transaction hash at all, the withdrawal is still pending at the platform you are sending from and the funds have not reached the network yet. If you have a hash and its status is pending, it is still confirming, and the balance usually appears within minutes on Polygon. If the transaction is confirmed and nothing has appeared, check three things in the block explorer: the network name, the contract address of the token that was sent, and the recipient address. The most common causes, in order, are: wrong network, then wrong token such as USDT or USDC.e, then an amount below the minimum. Do not resend with the same settings before you know the cause.
No. Deposits are made by sending USDC to your personal deposit address on the Polygon network, and withdrawals are made in USDC exclusively, to a Polygon address you supply. There is no bank withdrawal, no IBAN and no withdrawal to a card, and no fiat currency is handled inside the platform. So your cash-out plan should be ready before you need it: a receiving address you genuinely control, and advance confirmation that the receiving party accepts USDC on Polygon specifically.
There is no separate "emergency withdrawal" button; it is simply a matter of executing the ordinary withdrawal correctly the first time, because errors are what cause delay. First make sure the amount is in your available balance and not inside an open market, then prepare a receiving address on the Polygon network that you control, and verify that the receiving party supports USDC deposits on Polygon. If the address is new, run a small test withdrawal first and send the rest once it arrives. Note that address validation checks the format, not the ownership: a well-formed address may belong to someone else, and sending to it is final.
No. PolySouq does not use a "connect your wallet" model at all. The model is a personal deposit address: you get an address tied to your account on the Polygon network and send USDC to it from any wallet or platform you own. That means you sign no smart contract and grant no spending allowances from your wallet, which is in several respects simpler and less risky than wallet-connection flows. In exchange, the responsibility for choosing the correct network and token rests entirely with you.
No. PolySouq runs on a parimutuel pool model: everyone backing a given outcome puts their money into one shared pot, and at settlement the holders of the correct outcome split that pot pro-rata by each person's own stake, with every winner's original stake returned in full on top of the profit share. There is no party taking the other side against you and no bookmaker setting odds in its own favour; the platform earns only a 10% commission taken from the losing side alone at settlement. The logical consequences of this model are clear: if nobody is on the other side, everyone gets their money back and the commission is zero. This is event trading in which implied prices are determined by how participants' money is distributed — not a game of chance against the platform.
In all of those cases the money is returned. If there is no counterparty at all — that is, the losing side totals zero — everyone recovers their stakes in full and the commission is zero. If nobody backed the winning outcome, the market is voided, all stakes are returned, and the commission is again zero. And if the operator cancels a market for any reason, the refund is full and never partial. In football specifically, you can cancel your stake before kick-off with a full refund. In every case the system asserts that total payouts plus commission equal exactly the total staked into the market.
Native USDC on Polygon is the token issued directly on the network, whereas USDC.e is a bridged version coming from Ethereum on an entirely different smart contract, and it may appear in your wallet as "USDC (bridged)". The names are similar and the values are close, but the system reads the contract address, not the displayed name, so the two are treated as different assets. The safe assumption is that what is required is native USDC on Polygon, and that you should not send USDC.e without explicit confirmation of support. The same goes for USDT: even sent on the correct Polygon network, it is an unsupported token.
It depends on where you are sending from. If you are withdrawing from a centralised exchange, the exchange handles gas and you do not need POL at all. If you are sending from a self-custody wallet, it must hold a small POL balance, otherwise the send fails before it is even broadcast, even if you hold thousands of dollars of USDC. Note that you do not need POL to receive funds when withdrawing from PolySouq, but you will need it later to move those funds out of your wallet, so always keep a small POL balance in your receiving wallet. Gas fees on Polygon are typically fractions of a cent, and they are entirely separate from the platform's commission.
No. Positions at PolySouq run to settlement; there is no sale and no early exit mid-event, and there are no stop-loss orders, no leverage and no margin. The only exception is football markets, where you can cancel your stake before kick-off with a full refund of the amount. This constraint should govern the funding decision itself: decide the size of what you commit before you enter, not after, and do not commit money you may need within days. Remember that the money is real and losing the full amount committed is a live possibility.
On the Polygon network blocks are produced within seconds, and the system needs a sufficient number of confirmations before crediting the balance, so a deposit usually appears within minutes. Longer delays typically come from off-chain: withdrawals from centralised platforms pass through internal review and processing queues that can take minutes to hours, and during that window there is no on-chain transaction at all. The practical rule: if you have no transaction hash, the problem is at the sending platform; if you have a confirmed hash and no balance, the problem is the network, the token or the address.
