Key Features

⚡
SellingAgent onboarding in ~60s
One command, five steps: ENS subname registered, Splitter contract deployed, ERC-8004 agentId minted, CCIP-Read resolver wired, live.
🔗
Risk fee drops as trust is earned
Every settled payment writes an ERC-8004 attestation on-chain. Reckon402's risk engine reads it back via ENS CCIP-Read and reduces its routing fee — automatically, from on-chain data, no trusted intermediary.
🔐
Seller sovereignty
ENS subname and ERC-8004 agentId are owned by the seller's wallet. Platform can't revoke your identity or lock your funds.
