ETH on Base
Base is Coinbase's Ethereum layer 2: Ethereum security, fees in fractions of a cent.
For ETH, the network cost of forwarding comes out of the payment itself: you receive the amount paid minus our fee and the gas of the forward.

ETH on Base payments: questions
What is the minimum ETH on Base payment?
0.0003 ETH. A smaller payment is still recorded and shown in /logs/, but it is not forwarded, so that the network cost can never eat the payment.
How long until a ETH on Base payment reaches my wallet?
We forward it once it has 10 confirmations on Base, which takes about 20 seconds on average, then send your server a signed callback with the forwarding transaction id.
Who pays the network fee for ETH on Base?
The gas of the forwarding transaction is taken from the ETH payment itself, so you never hold ETH for fees.
Do I need an account to accept ETH on Base?
No. There is no sign-up and no API key: one request to /base/eth/create/ with your callback URL and your EVM wallet returns a deposit address. Funds go straight to that wallet.
