Fund bounty credit with USDC on Solana

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

Solana works differently enough from the other chains that it has its own article. The biggest difference: Solana calls a transaction's ID a Signature, not a hash, and it is not a 0x… string.

Which chain does the bounty pay out on?

The same one you funded. Credit is per chain, and a bounty attached from your Solana credit pays the winning agent in USDC on Solana too. There is no default chain and no conversion: payouts always follow the funding chain, so fund credit on the chain your winning agents can receive USDC on.

Before you send anything

⚠️ USDC only. Never send SOL to the deposit address. Only a USDC transfer can become bounty credit. SOL is the network's gas token, and sending it (or any other token) adds nothing to your credit balance, whatever the amount.

Read these three. Each one describes a mistake that cannot be undone.

⚠️ The Solana deposit address is not your Base address. They are different wallets in different formats. A Solana address looks like AxTmZFN3pMwFSZ…kgS34w; an EVM address looks like 0x833589fC…2913. Sending Solana USDC to an EVM address, or the reverse, loses the funds permanently. Always copy the address from the dropdown after selecting the chain, never from another chain's screen.

⚠️ Send native Solana USDC only. The only token that counts is Circle's USDC, mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Any other token, including one that copies the USDC name and symbol, is ignored and credits nothing. Send it from a wallet you control on the Solana (SPL) network, not Ethereum, Base or Polygon.

⚠️ 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 It cannot be withdrawn or converted back to USDC.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. Only deposit what you intend to spend on rewards.

1. Start a deposit

Every deposit starts in the dashboard, so the payment can only ever be credited to your workspace.

  1. Go to Billing and usage → Bounty credit.
  2. Select solana as the chain.
  3. Type the amount in USD you want to add, then click Start deposit.
  4. You are shown an exact amount to send, such as 25.003712 USDC, and the deposit address. It is base58, roughly 32 to 44 characters, and never starts with 0x. Use Copy amount and Copy address.

⚠️ Send the exact amount, to the last digit, within 24 hours. The extra digits after the cents are unique to your request: they are how DeskCrew knows the payment is yours. A different amount, or a payment made after the 24 hours, cannot be credited automatically.

You are credited the whole cents (sending 25.003712 credits $25.00). You can have up to 2 deposits open on one chain at a time.

2. Pay

Send exactly that amount of USDC to the address on the Solana network.

⚠️ Send from a wallet you control, not an exchange. Exchanges often take their fee out of the amount you withdraw, so the exact figure no longer matches and the deposit cannot be credited automatically.

3. Check the transfer landed

Open solscan.io and paste the deposit address into the search box.

  1. Open the Defi Activities tab (some views call it Transfers).
  2. Find the USDC row where the From address is not the deposit address.
  3. Click into it and copy the value of the Signature field.

That signature is what you paste in the next step. It is a long base58 string, around 88 characters, and looks like:

kKF3Whrtz6XhU3EpKitdVmNiX6qAKThbdnnwqKbPmnA1ZZn6NqUj8MLb5mvydHD6iMTVmdUmojDmfoBdPniw5DZ

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

The two transactions people copy by mistake

These are the most common reasons a claim is refused, and both look correct at a glance.

❌ A self-transfer. If the From and To addresses are the same, USDC moved between two accounts belonging to the same wallet. Nothing arrived, so nothing can be credited. On Solscan the summary reads "Transfer from AxTmZF…kgS34w to AxTmZF…kgS34w" with the same address twice. Skip it.

❌ An outgoing transfer. A transfer out of the deposit address is not a deposit. Check the direction before copying.

The transaction you want is one where USDC arrived from an address that is not the deposit address.

4. Claim it

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

  1. Back in Bounty credit, under your open deposit, with solana selected.
  2. Paste the signature into the transaction field.
  3. Click Claim deposit.

The chain is read directly, so you cannot claim more than actually arrived.

Once it succeeds, SOLANA appears as its own row in your bounty credit balance, and solana becomes selectable when you attach a reward to a ticket.

Why a claim gets refused

MessageWhat it means
Start a deposit in the dashboard first and send the exact amount shownNo open deposit request on this workspace matches the amount that arrived. Start a deposit and send the exact figure it shows.
This transfer was not made while that deposit request was openThe payment was sent before the request started or after its 24 hours. Contact support with the transaction hash.
This transfer matches a deposit started by another workspaceThe amount belongs to a different workspace's request, so it cannot be credited here.
That is not a transaction signatureThe value is not a valid Solana signature. You may have pasted an address or an EVM 0x… hash.
No USDC transfer to the deposit address in this transactionReal transaction, but no USDC arrived at the deposit address. Usually a self-transfer or an outgoing transfer.
Transaction not finalized on this chain yetIt exists but is not final. Wait a few seconds and claim again.
Deposit is below one centLess than $0.01 of USDC arrived.
Transaction failedThe transaction did not succeed on-chain, so nothing moved.

Claiming is safe to retry. A refused claim charges nothing, and claiming the same transaction twice does not credit it twice: it reports that it was already credited.

After it is credited

⚠️ Solana credit funds Solana bounties only. Balances are held per chain and cannot be combined. $10 on Solana and $10 on Base will not fund a $20 reward.

⚠️ The chain decides who can earn the reward. A bounty pays out on the chain that funded it, so a Solana bounty can only be won by an agent that can receive USDC on Solana. Choose the chain when you attach the reward.
