DeFiMath

DeFiMath is open-source, high-performance Solidity library for math and derivatives. Options, binaries, greeks, ln, exp, pow, stdCDF...

Black-Scholes on-chain for 2,876 gas.

DeFiMath: 40+ Solidity primitives. Precision <1e-12. Pure Solidity, 0 deps, MIT.

@TotalWorldApps Give me the link to github repo, I can take a look.

[DeFiMath @defi_math]

Solidity devs,

what are you building right now?

Drop a link + one line on what it does. Let’s connect, share notes, and actually support each other instead of shilling into the void.

I’ll go first 👇
DefiMath - gas-optimized on-chain math (Black-Scholes, Greeks, etc)

@ZealynxSecurity Do you guys grant to projects doing libraries and tooling like mine?

[DeFiMath @defi_math]

@programmerByDay Yes, under MIT license. Check it on website or github, I ran benchmarks against other libs and reference implementations, its fastest and also really precise, with max relative errors around e-12.

[DeFiMath @defi_math]

@badeniyiBas Great, good luck with your project!

[DeFiMath @defi_math]

DeFiMath v3.2.0 - 7 new utility math primitives.

→ mulDiv (512-bit, Remco Bloemen): 155 gas
→ mul (a·b/1e18, constants baked in): 130 gas - ~16% cheaper
→ abs/min/max/clamp/avg: branchless, sub-25 gas

DefiMath is launching on ProductHunt, give me an upvote for more visibility.

@7xuanlux Awesome, followed back.

@pcshipp No, not 100x.

2x maybe

[DeFiMath @defi_math]

@ardent__dev That’s how it started. I was building options exchange and needed Black-Scholes on-chain. Had to reimplement it because it was to expensive. Reduced the cost from 100k to 2.9k gas. Now it’s the fastest math library in Solidity!

Almost $1B hacked in #defi in 2026 (so far). Reminder to keep it simple.

[CD Security @CDSecurity_io]

Curious about Web3 hack stats this year? Here is the data:

January: 16 hacks, $86M lost
February: 15 hacks, $26.5M lost
March: 20 hacks, $52M lost
April: 40 hacks, $647M lost
May: 40 hacks, $81.7M lost

Total so far in 2026:
131 hacks
$893.2M lost

We need to do better. 🙏

How a single EVM opcode (CLZ, EIP-7939) powers DeFiMath's sqrt (245 gas), cbrt (368), and ln (375). It also makes Black-Scholes option pricing ~10% cheaper as a side effect.

🚀 DeFiMath v3.1.0 is out — now with `cbrt`, a fixed-point cube root for 18-decimal Solidity.

⚡ 368 gas avg — ~33% cheaper than Solady's cbrtWad (550 gas)
🎯 Bit-exact precision, no trade-off
🔧 CLZ + Newton-Raphson, single-branch
