SDK settlement is live on Polygon (default) today. The full contract stack
is deployed across the chains below; the Solana program is deployed, but its
b2b_pay_with_split settlement instruction and per-chain SDK routing are still
rolling out. All Cores carry the canonical manifesto hash 0x27b28e30….Full Core — 7 chains
Core + AgentPassport + mSECCO, with Pyth-priced settlement.
Each Full Core chain also deploys AgentPassport and mSECCO; Base and
Unichain additionally have a standalone B2BSplitter. See the
manifest for the complete address set.
Splitter — 3 chains
Atomic split settlement via the B2BSplitter (no oracle).Splitter MVP — 2 chains (non-EVM)
Also live on testnet: Casper (Agentic Buildathon — an agent settlement
layer) and Sui (Move).
Fee model
A flat protocol fee is added on top of the provider’s price and settled in one transaction — 99% provider / 1% treasury / 0.01% creator. No token, no staking — pay per request. Treasury is multisig-owned.How an agent proves payment
- EVM chains: the on-chain split tx → resend with
x-tx-hash+x-order-id. - Solana: Ed25519 signature over a one-time nonce +
b2b_pay_with_split→x-solana-tx+x-order-id.
