🟢 The simple version
Plain English — no jargon. Start here.
Exactly Protocol introduces fixed-rate DeFi lending on Optimism and Base via maturity pools — lenders lock capital for set durations at guaranteed fixed rates, creating an on-chain yield curve similar to bond markets, alongside variable-rate markets in the same protocol.
Fixed-rate DeFi lending
Aave/Compound: floating rates that change every block (unpredictable). Exactly: maturity pools (1-week, 4-week, 12-week USDC, etc.) with guaranteed fixed rates for the duration. Lock capital → earn guaranteed rate → receive principal+interest at maturity. Different maturities have different rates (yield curve — like bonds). Variable-rate market also available in same interface. ~10M EXA low supply. Is EXA legal in India? Yes. 30% tax, 1% TDS apply.
🟡 A bit more detail
For when you want to go a little deeper.
EXA vs Notional Finance
Both fixed-rate DeFi lending. Notional (NOTE): Ethereum mainnet, fCash tokenised fixed positions, deep DeFi composability. Exactly: Optimism + Base, combined fixed/variable in one protocol, more accessible UX. Exactly's L2 deployment makes fixed-rate lending viable (complex transactions would be gas-prohibitive on mainnet).
