Agon is a non-custodial clearing and settlement protocol for machine payments on Solana. It is designed for repeated, high-frequency relationships — agents paying APIs, services paying services, and operators routing payments between both — where settling every interaction as its own on-chain transfer is too expensive. Agon decouples payment execution from settlement. Participants exchange signed cumulative commitments off-chain in the hot path, then settle only the latest valid state on-chain. The same protocol supports direct settlement for one channel, bundled settlement for one payee, and cooperative clearing rounds across many participants.

What Agon provides

  • Permanent participant identities. Every wallet registers once and keeps a stable participant_id for the life of the deployment.
  • Permanent payment channels. One one-way channel per payer → payee → token triple. No close-and-reopen lifecycle.
  • Signed cumulative commitments. agon-cmt-v5 is the unilateral hot-path message. The payer signs the new cumulative target; the payee settles the delta later.
  • Three settlement modes. Direct settlement, bundle settlement, and cooperative clearing rounds — all settling into the same shared vault.
  • Non-custodial by construction. Balances live in program-owned accounts. Operators and facilitators can help submit settlements without holding funds.

​
Who Agon is for

Agon is a good fit when the same parties interact repeatedly and per-payment settlement cost matters:
  • agent-driven API and tool consumption
  • metered service relationships (inference, RPC, data feeds, compute)
  • operator hubs routing payments between users and providers
  • payment networks among a known set of counterparties
It is not intended to replace Solana’s native transfer for one-off, high-value payments.
