🆕 A B20 Stablecoin's currency() is SELF-DECLARED — the standard verifies nothing. This is the missing check: declared peg vs actual DEX market price. 'Says USD, trades at $0.71' in one call: on_peg / depeg_warning / depegged / no_market (the peg is a pure claim with zero price discovery) / unverifiable_fx for non-USD pegs. Run before settling in any B20 stablecoin.Overview
