Intent-Centric AI Agent Payment Protocol for Cronos x402
IntentFi is an intent-centric payment protocol built on the Cronos x402 ecosystem that transforms how users interact with AI agents for DeFi operations. Instead of paying per API call, users express financial intents (goals) and AI agents compete to fulfill them, receiving payment only upon verified successful execution.
