Game Economy

Solana on-chain game economy with a layered authority model across user wallets, hot inventory PDAs, persistent game keys, protocol manager co-signing, and operator-gated admin. Core flows include user and bank inventory, five-mint batch P2P trading, deposits and withdraws, treasury and fee-pool collection, loot-drop escrow, and a TypeScript reward loop that funds in-game payouts from accumulated trading fees.

Liquidator Engine

High-performance Drift liquidator that scans 45,000+ accounts every 50ms using Pyth Lazer and opportunistically liquidates high-risk positions, capturing tens of thousands of USD. A shortlisting microservice filters accounts by leverage, liquidation proximity, and risk weightings. A gRPC transaction service races dual submissions — high Jito tip / low fee and low tip / high fee — with nonce accounts so the slower confirmation is canceled.

Angmar

Permissionless vault protocol developed & designed to facilitate automated trading strategies on the Drift Protocol. Serving as a Solana-native implementation of Drift's vaults, Angmar manages user deposits and withdrawals while implementing delegate authority for secure strategy execution. Notably, it introduces features such as lock-in periods and a base high-water mark calculation on net-of-fees Net Asset Value (NAV), achieving a 50% reduction in compute unit consumption.
