Fund or withdraw

Supported deposit assets

Oddeon accepts Circle-issued native USDC on the following networks:

Token	Network	Chain ID	Token contract
Native USDC	Polygon PoS mainnet	137	0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359
Native USDC	Base mainnet	8453	0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913

These are the token contracts for Circle-issued native USDC. They are not deposit addresses. Send funds only to the unique address shown in Oddeon for your selected wallet and network. You can verify both contracts in Circle’s official USDC address list.

Only send native USDC on the selected network

Do not send USDC.e, USDbC, pUSD, USDT, MATIC, ETH, or any token whose contract does not match the table above. Selecting Base and sending on Polygon, or selecting Polygon and sending on Base, is also an incorrect transfer.

Deposit funds

1. Open the wallet page and choose Deposit.
2. Select USDC on Polygon or USDC on Base.
3. Check that your wallet or exchange shows the token contract listed above.
4. Copy the unique deposit address displayed by Oddeon or scan its QR code.
5. Check the minimum deposit shown in the app.
6. Confirm the token, selected network, deposit address, and amount before sending.
7. Send a small test amount first when using a new wallet or exchange.
8. Track the deposit until it is credited and available to trade.

Never send funds to the token contract. Do not replace the address shown by Oddeon with your regular EVM wallet address.

What happens after deposit

Oddeon creates a deposit address for the selected wallet and network. Once your native USDC arrives, the funding provider processes the selected route and credits your Oddeon balance. Oddeon handles any supported conversion needed for trading. You do not need to buy or send pUSD or other venue-specific collateral yourself.

Provider limits can change, so use the minimum and status shown in the app.

Deposit statuses

• Detected: Oddeon found the transfer.
• Processing: Network confirmation or conversion is underway.
• Submitted: The converted funds are on their way to the destination wallet.
• Completed: The balance is available in Oddeon.
• Failed: The funding process needs attention. Follow the displayed instructions before sending again.

Exchanges can take time to broadcast a transfer, and the selected network requires confirmations. The deposit may not appear immediately after the sender marks it complete.

Withdraw funds

Withdrawals are paid as Circle-issued native USDC on Polygon, using the same contract:

0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359

1. Open the wallet page and choose Withdraw.
2. Select USDC on Polygon.
3. Paste the destination address and verify it independently.
4. Enter the amount.
5. Review the amount to be received, fees, and conversion details.
6. Complete the required security confirmation.
7. Track the withdrawal until it reaches the destination.

Blockchain withdrawals generally cannot be reversed after submission.

Base support described above applies to deposits. For withdrawals, use only the asset and network shown on the withdrawal screen.

Before using an exchange address

For a deposit, confirm that the exchange can send native USDC on the network you selected in Oddeon. For a withdrawal, confirm that the destination accepts the asset and network shown on the withdrawal screen. One address may work across several networks, but that does not mean every network or USDC variant is accepted.
