Where I used it
- Decentralized Exchange Platform. This was the first thing I built that handled real money. It was an Ethereum DEX with MetaMask and Ledger support, so people kept their own keys the whole time. I built it alone over a summer when I was 15. While it was live it settled around 319,000 swaps.
- Chainlink Labs. I worked with Chainlink Labs on CCIP. Part of that was conformance testing for CCIP and ERC-677 across smart contract deployments that SWIFT was evaluating. The other part was execution infrastructure for cross-chain prediction markets, which ended up carrying a lot of volume. Since then I have kept building on the Chainlink Runtime Environment, CRE and CRE 2.0, for the workflow side of oracle work.
- Gether. Gether is a credit card that lets you spend against your stocks, crypto, and cash without selling any of it. I co-founded it and run it day to day. The compliance side, meaning the FinCEN registration, the AML program, and SOC 2, was built in-house rather than outsourced. The Solana Foundation and the Alchemy Foundation are grant investors.
