⚙️ What's inside
exp(), ln(), sqrt() — optimized to 1e-11 accuracy
stdNormCDF(), erf() — for on-chain Black-Scholes
<360 gas for sqrt
Safe bounds + minimal branching
All MIT licensed and composable with your contracts.
Solidity math is expensive. Most libraries either waste gas 💸 or sacrifice precision.
We built DeFiMath to solve this with:
- Pade approximations
- Fixed-point math
- Inline assembly for speed
🚀 Just dropped: DeFiMath — the fastest open-source math library for Solidity.
Gas-efficient, precision-optimized, MIT licensed.
From exp() to stdNormCDF() — everything DeFi protocols need, done right.
