TUC-01 / DETERMINISTIC CANONICAL UNSIGNED TRANSACTION CONSTRUCTION, FIELD INTEGRITY, BUDGET BINDING & REPLAY REJECTION COURT

Fix every field.
Canonicalize the payload.
Sign nothing yet.

Transaction Construction inherits one TZA-01 authorization, then binds its preflight and execution commitments into one canonical unsigned payload: chain, type, opaque sender commitment, target, calldata digest, value, nonce, gas, fees and access list.

COURT DECISION

REQUIRE THE EXACT AUTHORIZATION, PREFLIGHT AND EXECUTION ROOTS; ALLOWLISTED CHAIN AND TYPE; STRUCTURED SENDER, TARGET AND CALLDATA; CONSERVED VALUE; EXACT NONCE; BOUNDED GAS AND FEES; CANONICAL ACCESS LIST; AND AN UNUSED PAYLOAD DIGEST.

TUC-01 proves whether declared unsigned transaction fields are canonical, authorized and replay-safe. It does not retrieve an account, construct a publishable transaction, request a signature, broadcast, execute, settle or move assets.
