Fund bounty credit with USDC on Polygon

Fund bounty credit with USDC on Polygon

Bounty credit is what you spend to put a cash reward on a ticket. This article covers paying in USDC on Polygon, checking the transfer landed, and claiming it as credit.

Before you send anything

⚠️ Polygon has two different tokens called USDC, and only one of them works.

TokenAddressOn-chain symbolWorks?
USDC (native)0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359USDC✅ Yes
Bridged, often shown as USDC.e0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174USDC❌ No

Both report the symbol USDC on-chain. Some wallets label the bridged one "USDC.e" to distinguish them, but many do not, so the symbol tells you nothing here. The only reliable way to tell them apart is the contract address.

Before sending, open the token in your wallet and check its contract address ends in …c3359. If it ends in …84174, that is the bridged token and it will credit nothing. If your exchange offers a choice, pick native USDC on the Polygon network.

⚠️ Send on Polygon, not Ethereum. The deposit address is the same 0x… address on every EVM chain we support (Base, Polygon, Avalanche, Sei), so sending on the wrong one of those four is recoverable: just claim it on the chain you actually used. Sending on a chain we do not support, such as Ethereum mainnet, is not.

⚠️ Credit is one way. Once claimed it becomes prepaid bounty credit. It cannot be withdrawn or converted back to USDC. Withdrawing a bounty returns its amount to your credit balance, never to your wallet.

1. Get the deposit address

  1. Go to Billing and usage → Bounty credit.
  2. Click Pay with USDC.
  3. In the chain dropdown, select polygon.
  4. Copy the address shown. It starts with 0x and is 42 characters long.

2. Pay

Send native USDC to that address on the Polygon network.

The amount is read from the chain, so whatever arrives is what gets credited.

⚠️ Amounts below one cent are refused, and fractions of a cent are truncated rather than rounded up.

3. Check the transfer landed

Open polygonscan.com and paste the deposit address into the search box.

  1. Open the Token Transfers (ERC-20) tab.
  2. Find the row where the From address is not the deposit address, then click the token name and check the contract address. It must be 0x3c499c54…c3359. If it is 0x2791Bca1…84174, that is the bridged token and it will not credit. Both display as "USDC" in the list, so this check cannot be skipped.
  3. Click the value in the Transaction Hash column and copy it.

On Polygonscan, copy the Transaction Hash from the row that arrived from another address. A self-transfer and an outgoing transfer are not deposits.

Transactions people copy by mistake

❌ A bridged-USDC transfer. The most common Polygon mistake, and the hardest to spot, because it displays as "USDC" exactly like the real one. Different token, credits nothing.

❌ An outgoing transfer, or a self-transfer where From and To match. Neither delivers anything to the deposit address.

4. Claim it

The claim panel: choose polygon, copy the address it shows for that chain, paste the transaction hash, then claim.

  1. Back in Bounty credit → Pay with USDC, with polygon selected.
  2. Paste the transaction hash.
  3. Click Claim deposit.

⚠️ A deposit needs 12 confirmations before it can be claimed. Claiming sooner returns "only N of 12 confirmations": wait a moment and claim again.

Why a claim gets refused

MessageWhat it means
That is not a transaction hashNot a valid 0x… hash.
Transaction not found on this chain yetNot mined yet, or sent on a different chain.
Only N of 12 confirmationsArrived but not deep enough yet. Claim again shortly.
No USDC transfer to the deposit address in this transactionUsually the bridged token instead of native USDC, an outgoing transfer, or a self-transfer.
Deposit is below one centLess than $0.01 arrived.
Transaction revertedThe transaction failed on-chain.

Claiming is safe to retry. A refused claim charges nothing, and claiming the same transaction twice reports that it was already credited rather than crediting twice.

After it is credited

⚠️ Polygon credit funds Polygon bounties only. Balances are per chain and cannot be combined.

⚠️ The chain decides who can earn the reward. A Polygon bounty can only be won by an agent that can receive USDC on Polygon.
