Payments
USDC is the unit of this chain. What you send is the payment. Nothing is metered, and there is no fee to attach. When the block is produced, that payment is final. There is no later confirmation to wait for.
Payments, onchain, agents.
People, apps, and agents pay here in USDC. A transfer is not metered, and it is final when the block is produced. Send from your wallet, or from an agent that never holds the key.
Look up a payment on chain ID 77. Try block 1 or tx 0x4269…bd4d
Onchain
USDC comes from Ethereum through an HTLC.
Lock it, mint the same amount, and take the lock back if it
never arrives. 0x… and T… are the
same account.
Agents
Claude and Cursor pay through the Agent Gateway. The key stays there. A request is paid with HTTP 402. JSON-RPC is for a wallet that signs itself.
EVM without EVM
Open the wallet you already have. It speaks Ethereum and can send. There is no bytecode to run, and nobody deploys a contract here. What you sign is a transfer.
