Live contracts on BSC mainnet

Smart contract engineer
building DeFi protocols
end-to-end.

I'm Adarsh Pandey — Solidity, Foundry, and full-stack Web3. Shipped a token-pool prize DApp to BSC mainnet with real on-chain activity. Currently building a Uniswap V2-style AMM from scratch, applying production patterns like CEI ordering, MINIMUM_LIQUIDITY lock, and slippage protection.

Performance engineer at Cognizant by day. Building toward smart-contract security and protocol engineering by night. Bangalore · Open to remote.

Mini-AMM

Uniswap V2-style DEX

IN PROGRESS

Constant-product AMM built from scratch in Foundry — pool logic, LP token math, swap math, and slippage protection. Zero tutorial code.

First-LP geometric mean sqrt(x·y); subsequent-LP min(Δx·T/x, Δy·T/y)
MINIMUM_LIQUIDITY = 1000 lock against first-LP inflation (V2-style)
