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
