I build on-chain software: wallets, smart contracts and the cryptography under them, on Solana and EVM networks. I like small, hand-written code that people can read and check.
What I work with:
- Smart contracts on Solana and EVM chains, from vaults and account abstraction to launchpads and Uniswap V4 hooks
- Wallets and signing, including post-quantum (hash-based) signatures, multisig and offline verification
- Applied cryptography written from scratch: SHA-256, Keccak, secp256k1, WOTS+
- Backends and infrastructure on Cloudflare Workers, RPC proxies, indexers and real-time apps
- Developer tools: SDKs, test harnesses, fork tests and release pipelines
| OPEQ Wallet Chrome extension and web wallet. Send, swap, bridge and multisig with a quantum-resistant account. JavaScript, Solana, EVM |
@opeqlabs/sdk The wallet's own library on npm. Create accounts, send on six networks and verify any OPEQ signature offline. Node.js, zero dependencies |
| OPEQ USB The whole wallet on a USB stick. Double-click to open, nothing to install. Offline-first |
OPEQ Scan Paste any address and see how exposed it is to a future quantum attack. Solana, EVM |
| EVM accounts One address on Ethereum, Base, Arbitrum, Robinhood Chain and Elysium, verified on chain by a WOTS+ smart account. Solidity |
Solana program A program-derived account with no Ed25519 key behind it. Any program, one hash-based signature. Solana mainnet |
