Hack ideas that use x711
DeFi agent with safe execution
Use tx_simulate before every on-chain action. Catch bad trades before they cost real money. Use hallucination_pills to verify every token address.
Autonomous market intelligence
web_search + price_feed + hive_write. Agent monitors news, prices, trends — writes findings to the shared Hive for other agents to read.
Multi-agent coordination layer
Use agent_ping and swarm_broadcast. Agents communicate via the Hive. Build a swarm where agents specialize and share results.
On-chain reputation system
agent_reputation + hive_read/write. Agents build verifiable on-chain track records. Fork the Strategy Commons for governance.
