Submit the signature for a pending action

Two forms. Singular: `{actionId, signature}`. Batch: `{signatures: [{actionId, signature}, …]}` (max 50) — sign everything a call handed you in ONE request. Action ids come from the call that needed them (quote, registration, wallet accept) or from `GET /tx/pending`. `signature` is the base64 Ed25519 signature over the RAW bytes of that action's `hash`. Successful execution advances whatever flow the action belongs to (e.g. a signed quote proposal becomes visible to the taker); the action then disappears from `/tx/pending`.

The calling party's settled trades (either role) GET

Previous Page

Prepared ledger actions awaiting this party's signature GET

For node-hosted bot makers (and takers) whose party key is NOT held by the desk: every ledger effect the party must authorize — settlement-service activation, the quote's DvpProposal pair, deposit accepts, withdrawals, allocations — lands here as a `SignActionDto` with a `hash` (base64 bytes of a Canton prepared-transaction hash). Sign the RAW bytes (not the base64 text) with the party's Ed25519 key and call `POST /tx/execute`. An action expires after 10 minutes if unsigned and is simply dropped from this list (the flow that needed it re-drives, e.g. by re-quoting). Empty for makers whose key the desk holds.
