Flux
FLUENCE PRIZE · ETHGLOBAL NEW DELHISupport tools built for web2 don't understand transaction failures, wallet states, or protocol interactions, exactly the questions crypto users actually have.
Flux lets any crypto project deploy intelligent support agents with on-chain awareness: they read block explorers, diagnose failed transactions, and execute pre-authorized on-chain actions, all while keeping verifiable, immutable chat logs. Built at ETHGlobal New Delhi 2025, it won Best Use of Fluence Virtual Servers.
Three services: a Python uAgent agents service (ASI framework), a Node/TypeScript API for business logic, and a Next.js frontend serving both the admin dashboard and the embeddable widget. ENS gives each agent a verifiable identity; Fluence supplies decentralized compute so the support layer is never a central point of failure.

The hardest challenge was coordinating the uAgent framework with live blockchain data fetched at query time, pulling token balances, transaction status, and contract state and fusing them with indexed docs, without hallucinating protocol specifics:
query-time context
balances, tx status, contract state, fetched on demand
doc + chain fusion
indexed knowledge synthesized with live data
no hallucinated specifics
grounded answers, not plausible guesses
verifiable identity
ENS-named agents, immutable chat logs
