Croisette.cc

Hackathon project at ETHGlobal Cannes 2026. Effortless, 24/7 investing managed by AI agents on 0G's compute network. Won 1st place — Best OpenClaw Agent on 0G.

Croisette.cc is an autonomous investing platform built at ETHGlobal Cannes 2026. It targets two well-documented retail-investing failure modes: roughly 55% of people leave their savings in bank accounts where inflation eats them, and around 80% of retail investors lose money because they lack the time or expertise to manage a portfolio. Croisette replaces brokers and active management with AI agents that run 24/7 on top of 0G’s compute network — the user answers a few onboarding questions about goals and risk tolerance, and the agents take it from there.

How it works

A new user opens the app and answers a short questionnaire — their financial goals, time horizon, and risk tolerance. The Portfolio Builder agent turns that profile into a concrete portfolio across yield-bearing stablecoins and on-chain lending positions on the Arc testnet.

From that point on the Portfolio Manager agent takes over: it periodically snapshots wallet balances, prices each position via the Uniswap Trading API, and proposes rebalancing actions when the portfolio drifts from the target allocation. The user only signs the rebalances — the agents do the rest of the work, on a 24/7/365 cadence.

Architecture

The system is built around two cooperating agents orchestrated by a Next.js backend that calls 0G’s LLMs through the 0G-Compute-Adapter. Both agents are implemented on top of the ZeroClaw / OpenClaw agent runtime.

  • Portfolio Builder — risk assessment + portfolio construction, exposed as 7 specialised skills (questionnaire parsing, risk scoring, asset selection, allocation, etc.).
  • Portfolio Manager — balance snapshots, Uniswap-based pricing, drift detection, rebalancing proposals.
  • Wallet management — driven via cast.
  • Integrity — security-critical files are hashed into a manifest committed to 0G Storage, so any tampering with the agent code or its config can be detected on-chain.
