Evidence for AI agent payments

Independent reconciliation for agent payments.

Your agent declares a payment. Your wallet or provider executes. OCD independently observes supported settlement and reconciles the evidence.

The wallet signs. OCD reconciles.

100 completed free payment preflight evaluations per authenticated workspace per UTC month. Free-mode support for canonical Base USDC and Solana mainnet USDC. No OCD fee signer required; merchant payments and gas remain separate.

Inspectable recordsSigned receipts / LedgerSigned receipts: cryptographic evidence
Ledger: operational status view

OCD does not custody, sign or send payments. Policy ALLOW is not wallet authorization: enforcement requires a configured gate, not universal wallet blocking. Executor claims are not settlement; settlement is not merchant delivery. Some workflows have no execution or settlement.

Two real artifacts. One illustrative example.

Receipt VALID checks cryptographic integrity and authenticity, not settlement by itself, payment authorization or safety. Service quality or delivery was not independently verified.

Amount mismatch · investigation required. Inspect the differing evidence before deciding what to do; do not automatically repeat the payment.

No transaction, receipt or signature exists for this simulation. It is not a production incident.

Execution withheld. Decision documented.

Chainalysis and SEC EDGAR observations did not establish the required wallet-to-company binding. (Historical run; that sanctions oracle has since been retired. Current wallet screening uses the OFAC SDN List.)

What you can do today

One evidence layer. Four practical uses.

Supported payment lifecycle

Payment reconciliation & Ledger

Compare policy, executor claims and independently observed settlement in one operational view. Claims are not settlement.

What the statuses mean

The Reconciliation Ledger groups workspace activity as Accounted for, Needs attention or Pending: operational summaries, not verdicts on authorization, payment safety or merchant delivery. Preflight compares policy; your executor pays; OCD observes supported settlement.

Configured MCP / x402 flows

Auto-Evidence & executors

Capture evidence around supported flows using the published MIT Auto-Evidence proxy prerelease. Your external executor keeps control; arbitrary payment paths are not automatically intercepted.

Supported flows & references

Use explicitly configured economic MCP tools and x402 v2 exact flows. Base USDC is the default; Solana mainnet USDC is opt-in. Turnkey is a completed technical reference execution flow, not a partnership, endorsement or universal compatibility claim. No funded live packaged-proxy canary has occurred.

Wallet Evidence

Connect a wallet or inspect an address. Correlate supported observed transfers with existing workspace evidence. Unlinked activity stays Unlinked.

Bounded, user-triggered observations are live chain reads, not signed; they do not prove wallet ownership or agent identity.

Network scope & receipt creation

Tracker networks: Base · USDC, Tempo · pathUSD and Arc · USDC. Creating a receipt is a separate, explicit action; viewing activity is read-only, not arbitrary wallet history.

Supported completed transfers

Past-payment receipts

Provide a supported network and transaction reference. OCD independently observes the transaction and issues an observation-only signed receipt.

Historical policy remains UNKNOWN: this is not authorization of the original payment.

What the receipt can establish

Only supported transfers are covered. Receipt VALID checks integrity, not settlement by itself; a receipt does not establish merchant delivery or wallet identity.
