How this service works

Signed statement of account for an agent wallet: every outgoing USDC settlement in a window, read independently from the public Base chain, totalled by counterparty and by day, block-anchored and ed25519-signed so anyone can verify it without Orcpin. Optionally attests the requester's own meter figures as reported, by digest, kept apart from the verified chain facts. The books a wallet does not keep. Counts and amounts only, never advice; nothing stored.

Output

A signed statement object containing: all outgoing USDC settlements from the specified Base wallet in the requested window, aggregated by counterparty and by day; a block anchor tying the data to a specific on-chain block; an ed25519 signature over the statement so any party can independently verify it without involving Orcpin; and, if representations were supplied, an attestation of the requester's meter figures (metered calls, delivered calls, delivered USD, and sha256 digest) clearly separated from the verified chain data.

Example use cases

Monthly agent wallet reconciliation

“Give me a signed USDC settlement statement for my agent wallet 0xAbCd...1234 covering all of last month — January 1 to January 31 2025 — so I can reconcile what actually went out on-chain against my internal records.”

Attested meter vs. chain audit

“Generate a block-anchored USDC statement for wallet 0xDEF0...5678 from 2025-02-01 to 2025-02-28, and also attest my meter figures: I counted 412 metered calls, 398 delivered calls, and $1,240.50 delivered USD — include the sha256 digest of my meter records so anyone can cross-check.”

Counterparty payment breakdown for compliance

“I need a cryptographically signed, independently verifiable record of every outgoing USDC payment from wallet 0x9A3B...CDEF between 2025-01-01 and 2025-03-31, grouped by counterparty and by day, so I can hand it to our compliance team without them having to trust us.”

When to prefer

Choose this endpoint when you need a cryptographically verifiable, independently checkable record of outgoing USDC settlements from a Base wallet — especially when the statement needs to be shared with third parties who cannot be asked to trust the requester. Prefer it over raw chain queries when you want pre-aggregated, signed, counterparty-grouped totals rather than raw transaction lists. Also prefer it when you want to co-attest your own internal meter figures alongside verified on-chain data in a single artifact. It is purely a read/audit endpoint with no stored state and no financial advice.

Side effects

Invalid wallet address format (not 0x + 40 hex) returns a validation error
Date range where since is after until returns an error
Providing only one of since/until without the other (partial bound) returns a validation error
Wallet with no outgoing USDC transactions in the window returns an empty but valid signed statement
Payment failure or x402 authorization error prevents statement generation
Base chain RPC unavailability or indexing lag may cause transient failures
Malformed representations object (missing required fields) returns a schema validation error
