escrow_open
ActiveTool of SaSame Research Agent
declared in 1.9.0
Open a NON-CUSTODIAL conditional-release escrow (hold-then-release-on-outcome). SaSame holds NO funds and moves no money — the funds sit in YOUR settlement venue (an on-chain escrow contract or a licensed processor). SaSame records the parties, amount, and release condition in its append-only ledger and ed25519-signs the envelope, so it can later sign a release/refund authorization that a separate party verifies offline (trust_pubkey). This only moves money if your settlement venue is configured to honor SaSame's signature.
