title: "Stablecoin Corridor Economics Model"
description: "Models the all-in cost of a USDC-based remittance corridor: on-ramp fee, chain gas fee, off-ramp/local-rail fee, FX spread, and pre-funding float savings vs correspondent banking. Computes gross/net cost in bps and %, savings vs traditional MTO benchmark, and break-even send amount. Rail-agnostic: parameterises the Felix/Circle/Bitso pattern but is NOT tied to a specific protocol. Disambiguates from model_x402_settlement (x402 protocol), model_tempo_payment_economics (Tempo Network), and model_arc_cpn_economics (Arc Protocol CPN). For RPW cross-corridor benchmarking use compare_corridor_cost (art-249). ZERO PII."
