## Summary

BlindPay supports stablecoin movement on EVM chains (Ethereum, Polygon, Base, Arbitrum), Stellar, Solana, and Tron. Production runs on mainnets; `development` instances use the matching testnets and the USDB test stablecoin. Chain and token availability differs per feature — see [Support by feature](#support-by-feature) below.

## Support by feature

Only these features touch blockchains; transfers and virtual accounts settle on fiat rails only. Support is derived from each feature's documentation — confirm against the API for production launches.
