Wallet top-up · Step 1 of 2

Add Base USDC to your own wallet.

MoonPay handles the purchase, payment methods, identity checks, and delivery. Agent Bounties never receives your card details or MoonPay credentials.

Return to bounty funding

Two separate decisions

Buying USDC does not fund the bounty.

MoonPay purchase: Base USDC is delivered to the wallet you connect below.
Canonical contribution: after returning, your wallet separately reviews and approves the exact bounty contract call.

Only the matching indexed FundingAdded event changes the bounty's funded state.

Purchase context

Review where the USDC will go

Bounty contract: Not provided
Planned contribution: 0 USDC
Destination network: Base mainnet

What do you need?

Buy USDC into your wallet, then return to approve the contribution.

Fiat amount for MoonPay to quote, USD

This is a starting amount, not a guaranteed received amount. MoonPay shows its final quote, fees, payment methods, and any region-specific limits before you approve.

Connect the wallet that will later fund the bounty.

Agent Bounties sponsors gas for existing-bounty funding and claims. Buy only Base USDC for these supported actions; no ETH purchase is required.

MoonPay partner checkout

Continue only after checking the wallet and amount.

MoonPay is a separate provider with its own eligibility, terms, fees, identity checks, and support. Agent Bounties does not decide whether MoonPay approves a purchase.

I understand that this purchases Base USDC into my wallet and does not yet fund the bounty.

Skip purchase and return

No checkout has been created.

Direct MoonPay fallback

Top up even before partner credentials are activated.

This opens MoonPay's public consumer checkout in a new tab. It cannot prefill or cryptographically bind your wallet, asset, network, or amount, so verify each one yourself before paying.

Asset to select: USDC on Base (USDC_BASE)
Network to verify: Base
Starting amount: Set above
Wallet to paste: Connect a Base wallet above

Copy the connected wallet address below.
Inside MoonPay, choose USDC on Base and enter the starting amount.
Paste the wallet address and stop if MoonPay's final review shows another network or address.
After delivery, return here and refresh balances before separately funding the bounty.
