Operational MPC wallets

Resume wallet

AUTHENTICATIONBearer token · operational-wallets:writeAUTHORITATIVE OWNERcore-operational-walletsCONTRACT AUTHORITYGenerated Rust OpenAPISTATUSSource ready · production listed

PURPOSE + BUSINESS CONTEXT

Resume an independently activated operational wallet without changing its workspace, network, purpose, or settlement target.

WHEN THIS CALL IS USEFUL

Call this when a wallet, treasury, custody, or governed agent workflow needs to apply the documented resume wallet transition after re-reading the current authoritative state so it can make a custody decision inside the correct owner, workspace, network, and policy boundary.

OUTCOME · Create or advance

What changes

Creates or advances only the resume wallet resource described by this contract after authorization, validation, policy, and idempotency gates pass.

WHY IT MATTERS

Gives people and agents a contract-backed way to advance resume wallet.
Makes custody state understandable without exposing seeds, shares, nonces, private keys, or other reusable signing material.

ISOLATION + AUTHORITY

The authenticated owner, workspace, network, and wallet policy remain authoritative. A wallet record, policy result, approval, ceremony, or balance never grants another lifecycle stage and cannot substitute for threshold signing or separately owned funding, settlement, publisher, matching, or trading authority.

BEFORE YOU CALL

Authenticate at the documented boundary: bearer+scope.
Supply the required wallet_uuid (path), reason (body) exactly as defined by the live contract.
Use one Idempotency-Key only for retries of the same byte-equivalent logical mutation.
Resolve the active workspace, network, wallet lifecycle, and applicable custody policy before relying on this result.

WHAT TO DO NEXT

Re-read resume wallet using the canonical identifier returned by this operation.
Reconcile an ambiguous response with the same idempotency key before attempting another mutation.
Re-read the wallet and policy state before the next governed action, especially after an ambiguous or concurrent result.

AGENT GUIDANCE

Use resume wallet only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Supply the required wallet_uuid (path), reason (body) exactly as defined by the live contract.
Keep enrollment, activation, policy evaluation, approval, ceremony, signing, submission, confirmation, and settlement as distinct states.
After a timeout or conflict, read authoritative state before deciding whether an equivalent retry is safe.

MACHINE CONTRACT

The exact deployed parameters, schemas, responses, security requirements, and Hybrid-Chain agent metadata are authoritative at this operation's production OpenAPI JSON Pointer. The readable tables below add integration guidance; the deployed OpenAPI controls if guidance and the machine contract ever differ.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then re-read resume wallet using the canonical identifier returned by this operation.
RETRY SAFETY: Do not repeat a successful mutation merely to confirm it. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Persist returned identifiers, versions, commitments, and receipts. Re-read the wallet, intent, reservation, and transaction status on the same network; compare policy version, nonce, digest, and terminal receipt before another command.

409The request conflicts with wallet or binding state, policy version, or a prior idempotent operation.State reconciliation required · JSON RESPONSE+

{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is invalid"
}

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Stop the mutation sequence and fetch the latest authoritative resource, lifecycle state, version, ETag, reservation, or existing idempotency result.
RETRY SAFETY: Retry only after reconciling the conflict. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Re-read the wallet, intent, reservation, and transaction status on the same network; compare policy version, nonce, digest, and terminal receipt before another command.
ESCALATE WHEN: Escalate when funds, reservations, transaction digests, or MPC state remain ambiguous after authoritative wallet and network reconciliation.

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Preserve the exact request and treat the outcome as uncertain until authoritative state proves whether it committed.
RETRY SAFETY: Reconcile before retrying. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions. Use bounded backoff with jitter.
STATE RECONCILIATION: Re-read the wallet, intent, reservation, and transaction status on the same network; compare policy version, nonce, digest, and terminal receipt before another command.

OPERATIONAL NOTES

Security and lifecycle guarantees

Resume an independently activated operational wallet without changing its workspace, network, purpose, or settlement target. Authoritative owner: core-operational-wallets.
The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
Mutations are retry-safe only when the same Idempotency-Key and canonical request body are reused.
Workspace and network context are derived from the authenticated principal and signed network assertion; callers cannot widen either boundary.
Each AI or merchant operational wallet has an independent MPC enrollment. The primary treasury cannot be assigned to an agent or merchant rotation.
Settlement is allowed only from an operational wallet to the immutable primary treasury in the same workspace and network.
Private key material, MPC shares, seeds, signing nonces, and participant secrets are never accepted or returned.
The tables and examples are derived from the current gateway source OpenAPI. Re-fetch the deployed OpenAPI before execution; deployment status is shown separately on this page.
Only parameters present in the OpenAPI operation are accepted; undocumented query keys fail closed with HTTP 422.
