Three additions covering all three payment-protocol families this list curates:

  • AP2 Implementation: AlgoVoi as a live facilitator with 7-chain USDC settlement + Solana Pay reference pubkey binding for tx<->PaymentMandate correlation.
  • x402 Implementation (Live Services): Single-endpoint multi-chain x402 facilitator spanning EVM (Base, Tempo), SVM (Solana), AVM (Algorand, VOI), Stellar, Hedera.
  • MPP Implementation: Registered service in the official MPP directory (tempoxyz/mpp #556).

AlgoVoi is the only entry that implements all three protocols on the same URL, which makes it a natural cross-reference for agents deciding between protocols. Production at api.algovoi.co.uk with open-source MCP adapter.

Three parallel additions — AlgoVoi implements all three protocols on a
single endpoint, which is a natural fit for this cross-protocol list:

- AP2 Implementation: live facilitator with 7-chain USDC settlement
- x402 Implementation (Live Services): multi-chain single-endpoint facilitator
- MPP Implementation: registered service entry (tempoxyz/mpp #556)

Notable: Solana flow uses Solana Pay reference pubkey binding for
cryptographic tx-to-mandate correlation — new primitive not otherwise
represented in the list.

Quick update for the listing context: AlgoVoi facilitator is now live across all 8 supported chains, with full x402 v2 + MPP + AP2 + A2A protocol coverage on each. Cross-chain support is the differentiator vs single-chain reference implementations. Public verification: agent-trust-bench.algovoi.co.uk (138 adversarial profiles × 8 chains, MIT-licensed). MCP server v1.4.3 on PyPI and npm. Active in protocol working groups: x402-foundation/x402 #2322 (Compliance category), tempoxyz/mpp-specs #225 (unified EVM session) and #258 (Hedera session), AP2 #250 (PQC). Happy to provide additional info.
