description: "Deterministic bind of an ISO 20022 pacs.008 (customer credit transfer) or pacs.009 (FI credit transfer) payment message to EVM contract-call arguments, plus an OCG receipt of the mapping: resolved call, field bindings, unmapped required fields, and ABI type coercions. Draft-pinned generic ISO-20022-to-EVM profile: Swift blockchain-based shared ledger MVP (Besu/EVM-compatible, live 2026-07-09) has not published a field-binding table or a fixed contract ABI shape. Never queries a chain or RPC."
