- Develop, deploy, and maintain production-grade smart contracts and DEX integrations

- Build multi-chain transaction infrastructure across EVM-compatible networks, Solana, and other non-EVM ecosystems

- Build and operate RPC integrations, blockchain nodes, indexers, reorg-aware chain listeners, and on-chain data pipelines

- Own the transaction lifecycle from policy checks and signing through confirmation, reconciliation, and recovery
