Solana Builder, Researcher, and Writer

Consumer and infrastructure products, protocol and security research, and the threads and reports that make it useful to others.

Profile

I ship consumer and infrastructure products across Solana and Circle's Arc. Most recently I founded and led Siren, a prediction market trading terminal that integrated Kalshi and Polymarket, Privy embedded wallets, and real-time PnL over live USDC and SOL balances, the same shape of problem as production prediction-market apps. I also run protocol and security research, including an independent Phase 1 audit of Toly's Percolator that was quoted and verified by Anatoly Yakovenko, and I write the threads, articles, and weekly reports that make the work useful to others. Solana builder since 2023 and Core Member at Superteam Nigeria.

  • Designed a natural language trading agent covering intent parsing, market matching, and edge-case handling, plus a risk layer for correlation and concentration.
