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)
@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.
@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!

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
