Introducing DeFiMath
The math layer for on-chain finance
Pricing options on-chain used to mean off-chain oracles or hand-rolled approximations. DeFiMath gives you 40+ Solidity primitives - Black-Scholes, Greeks, implied vol, rates, statistics - at gas costs lower than a single storage read, with precision under 1e-12.
2,876 gas - full Black-Scholes option pricing (call or put)
< 1e-12 error - verified against off-chain reference implementations
40+ primitives - Black-Scholes, binaries, Greeks, IV solver, futures, rates, statistics. See the full list →
0 dependencies - pure Solidity ^0.8.31, MIT licensed
100% test coverage - every branch, every edge case
