  • Decentralized Exchange (DEX) functionality (AMM, swaps, liquidity pools)
  • Wallet lock/unlock rules governed by governance proposals
  • Transaction volume caps and thresholds
  • Staking reward logic and slashing rules
• Optimize contract gas usage and security.

Bridge Integrations & Interchain Connectivity

• Experience deploying and upgrading production blockchains.
• Deep understanding of staking, governance, validators, tokenomics, and IBC.
• Prior work on DEXs, cross-chain bridges, or smart contract-based access control is a plus.
• Familiarity with blockchain monitoring, RPC/WebSocket endpoints, and chain analytics.
• Experience with forked chains, custom module development, and network upgrades.
• Strong version control (Git), CI/CD workflows, and Linux-based development.

Preferred Skills (Nice to Have)

• Knowledge of Hyperlane, Axelar, or other IBC bridge protocols.
• Familiarity with Cosmos governance tooling (Commonwealth, Keplr, etc.).
