What is FLAT?

FLAT is a CPI-pegged stablecoin on Ethereum. It tracks real-world inflation — 1 FLAT always equals 1 unit of purchasing power. Unlike USDT/USDC which lose value to inflation, FLAT preserves it.

No freeze function — immutable ERC-20, cannot be blacklisted
No KYC required — create an account with just a label
No gas needed — internal transfers are free and instant
Privacy — BearerSwap enables untraceable transfers
