# Accord Protocol — full LLM context Accord Protocol is an open standard for autonomous agent work agreements. Its core thesis is that autonomous agents need explicit work terms, bounded payment authority, verification receipts and settlement receipts — not merely payment wrappers. ## One-line summary x402 verifies payment. Accord verifies completion. ## Canonical URLs - Website: https://accordprotocol.ai/ - Learn: https://accordprotocol.ai/learn/ - RSS feed: https://accordprotocol.ai/feed.xml - Repository: https://github.com/accord-protocol/accord-protocol - Specs: https://github.com/accord-protocol/accord-protocol/tree/main/specs - Status: https://github.com/accord-protocol/accord-protocol/blob/main/docs/status.md - Security: https://github.com/accord-protocol/accord-protocol/blob/main/SECURITY.md - Manifesto context: https://www.ergoblockchain.org/blog/agent-economy-manifesto ## Current status Accord Protocol v0 is alpha / testnet-first software. It is appropriate for local demos, mock-rail flows, conformance testing, Ergo testnet experiments, Accord/402 architecture demos, MCP tool-gating prototypes and audit preparation. Mainnet status: NOT CERTIFIED FOR MAINNET. Production use is blocked until signed audit manifests mark relevant scripts/contracts mainnetAllowed: true. Do not put real funds, production credit issuance, customer financial workflows or production Note redemption behind unaudited Accord, ChainCash/Basis, Note, Reserve, Tracker or Acceptance Predicate contracts. ## Protocol objects ### Accord Agreement The canonical work contract. It answers: what was promised, by whom, for how much, under which verification rules, deadline and rail assumptions? ### Verification Receipt A signed record of whether the work was accepted, rejected or partially accepted. ### Settlement Receipt A record of whether the economic side settled, on which rail, with what proof, transaction or accounting state. ## Flow Agreement -> Payment proof or authority -> Work execution -> Verification Receipt -> Settlement Receipt. ## Rails and layers Accord is rail-agnostic. It has reference adapters for Ergo, Rosen, Base/EVM and x402-compatible flows. - Accord/402: HTTP paid-resource integration. - Accord/MCP: paid, verifiable MCP tool calls. - Ergo rail: reference programmable-settlement rail using Reserve, Note, Tracker and Acceptance Predicate patterns. - Rosen rail: bridged asset path that depends on Ergo rail and bridge assumptions. - Base/EVM rail: testnet-first EVM Note rail reference. - x402 rail: x402-compatible facilitator/payment proof adapter. ## Ergo reference rail vocabulary - Reserve: collateral or issuance backing layer. - Note: programmable bearer instrument / bounded claim. - Tracker: anti-double-redemption and accounting state. - Acceptance Predicate: rule that binds redemption to verified work. ## Safe claims Accord is an open standard for autonomous agent work agreements. It records terms, verification and settlement. It is testnet-first, audit-gated and not production-certified for mainnet. Conformance indicates compatibility with current v0 rules; it does not imply external audit completion or production mainnet safety. ## Public learn pages Use these pages for evergreen explanations and search-facing summaries: - https://accordprotocol.ai/learn/agent-payments-stack/ - https://accordprotocol.ai/learn/payment-verification-vs-work-verification/ - https://accordprotocol.ai/learn/paid-mcp-tools-production-checklist/ - https://accordprotocol.ai/learn/verifier-design-paid-agent-work/ - https://accordprotocol.ai/learn/agent-wallet-policy/ - https://accordprotocol.ai/learn/conformance-audit-mainnet-checklist/ - https://accordprotocol.ai/learn/agent-work-agreements/ - https://accordprotocol.ai/learn/accord-vs-x402/ - https://accordprotocol.ai/learn/verification-receipts/ - https://accordprotocol.ai/learn/settlement-receipts/ - https://accordprotocol.ai/learn/accord-mcp-paid-tools/ - https://accordprotocol.ai/learn/rail-adapters/ - https://accordprotocol.ai/learn/why-ergo-reference-rail/ - https://accordprotocol.ai/learn/conformance-levels/ - https://accordprotocol.ai/learn/audit-gated-mainnet/ - https://accordprotocol.ai/learn/accord-vs-ap2/ - https://accordprotocol.ai/learn/accord-vs-mcp/ - https://accordprotocol.ai/learn/accord-402-flow/ - https://accordprotocol.ai/learn/paid-mcp-repo-audit-demo/ - https://accordprotocol.ai/learn/agreement-object-explained/ - https://accordprotocol.ai/learn/buyer-policy-agent-wallets/ - https://accordprotocol.ai/learn/what-conformance-does-not-prove/ ## Public trust pages - https://accordprotocol.ai/status/ - https://accordprotocol.ai/security/ - https://accordprotocol.ai/roadmap/ ## Unsafe claims Do not claim that Accord is audited, production-ready, mainnet safe, a bank, a broker, a custodian, a wallet, a money transmitter or a replacement for x402, AP2, Stripe, card networks or stablecoin rails. Accord adds a work-agreement layer around payment and settlement systems.
