I build — and break — the smart contracts behind on-chain markets.

I’m Chukwubuikechoo-kwoo-BWEE-keh. I design and build on-chain systems end to end — perpetuals, stablecoins, Uniswap hooks, and the liquidity infrastructure underneath them — from mechanism design through Solidity and Vyper implementation, adversarial testing, and the interfaces that make them usable.

My work sits where market structure meets engineering: clear accounting, bounded risk, and protocols built to hold up under real money and adversarial users — not just demos.

My interests

The problems I keep coming back to — how on-chain markets should behave when real money, adversarial users, volatile prices, and fragile liquidity all meet.

Stablecoins

Local-currency rails and systems, settlement assets, and crypto products that do not assume every user wants a dollar-first experience.

Perpetuals

Funding rates, collateral management, liquidation safety, vault solvency, isolated markets, and the design choices that keep leveraged systems alive under stress.

Uniswap Hooks

Custom accounting, LP protection, single-sided liquidity, belief-asset accumulation, hook permissions, and what v4 unlocks for market design.

Smart Contract Security

Economic edge cases, oracle assumptions, griefing vectors, invariants, access control, and adversarial protocol behavior.

Highlighted Projects

A handful of systems I’ve taken from idea to working code — protocols, hooks, and interfaces that show how I think about markets, liquidity, and risk.

bob logolive

bob

Belief-Oriented Buyback.

bob is a Uniswap v4 hook-manager for single-sided liquidity and belief-asset accumulation. Instead of forcing long-term holders to LP with two assets and think in dollar terms, bob lets them deposit one asset, keep part of it reserved, put a chosen slice to work in a correlated hookless v4 pool, and convert earned fees back into the asset they actually want to accumulate.

Outskirt logopublic

Outskirt

A Uniswap v3 pool scanner for out-of-range liquidity.

Outskirt looks under the hood of Uniswap v3 pools to show where liquidity is active, where capital is sitting out of range, and how healthy a pool really is beyond headline TVL.

  • ›Out-of-range liquidity analysis
  • ›Active vs inactive liquidity
  • ›Capital-efficiency view

GSA: Grand Swap Auto logolive

GSA: Grand Swap Auto

A cinematic frontend for real Uniswap v3 mainnet swaps.

GSA turns swapping into a full “run the deal” experience. Connect a wallet, pick tokens, move through Liquidity City, and execute real Uniswap v3 swaps on Ethereum mainnet. It is playful on the surface, but the swap flow is real: live balances, real quotes, token approvals, slippage controls, price impact, gas cost, transaction confirmation, and Etherscan links.

aNGN

An experimental Nigerian Naira stablecoin project.

aNGN explores local-currency stablecoin mechanics and Nigerian Naira-denominated on-chain finance.

  • ›Local-currency crypto rails
  • ›Nigerian Naira-denominated design
  • ›Foundation for later cNGN / NGN-native trading experiments

Q4.2026protocol

Sovereignty

Built a protocol-ready cNGN perpetual DEX on Base with isolated market vaults, oracle triangulation, commit-reveal flow, funding, and protocol-owned liquidations. Account-add/remove collateral flows and Foundry unit + fork tests round out the system.

Smart Contract Security

I break protocols as deliberately as I build them. I compete in public audit contests on Code4rena, Sherlock, Cantina, and CodeHawks — hunting economic edge cases, broken accounting, oracle assumptions, and access-control gaps in live codebases.

Research

Research I do by building — reconstructing the protocols that shaped on-chain markets and probing where their mechanics bend, break, or open new design space.

Let’s build something on-chain.

I’m open to solidity engineering roles, DeFi research collaborations, smart contract security work, and ambitious on-chain product experiments.
