Decentralised Lending Protocol

Confidential — Series B FinTech

Ethereum + Arbitrum

Designed and audited a collateralised lending protocol supporting 12 asset types with dynamic interest rate models. Achieved $48M TVL within 90 days of mainnet launch.

Challenge

The client had an existing prototype with critical reentrancy vulnerabilities and an interest rate model that would have been exploitable under low-liquidity conditions. They needed a full redesign, not a patch.

Solution

We rebuilt the core lending engine from scratch using a pull-over-push pattern, implemented Chainlink price feeds with TWAP fallback, and designed a tiered liquidation mechanism that protects the protocol under extreme market conditions.

AAA Game Studio Web3 Integration

Confidential — AAA Game Studio

Immutable X (StarkEx)

Integrated gasless NFT minting and a secondary marketplace into an existing PC game with 2.1M active players. Processed 340,000 NFT transactions in the first month.

Challenge

The studio needed blockchain integration that felt invisible to non-crypto players — no wallet popups, no gas fees, no seed phrases. The existing game engine (Unreal 5) had no Web3 SDK.

Solution

We built a custom Unreal 5 plugin wrapping Immutable X's StarkEx rollup, implemented embedded wallet creation via email/social login, and designed a gasless minting flow that required zero blockchain knowledge from the player.
