      "description": "Linear two-step chain for stablecoin remittance corridor economics analysis. Step 1 models the all-in cost of a USDC-based corridor (on-ramp fee, chain gas fee, off-ramp/local-rail fee, FX spread, and pre-funding float savings vs correspondent banking). Step 2 benchmarks total cost against the World Bank RPW Q1 2026 snapshot for the same origin-destination pair and the SDG 10.c 3% target. Together they surface whether a stablecoin corridor meets the SDG 3% goal and how it compares to the World Bank corridor average. Both steps always run.",
