Phase 0 is now. The Hyperliquid-first rebuild landed on November 3, 2026, and on November 11 the vaults go live on HyperEVM testnet and Circle Arena Season 0 begins.

​
What ships

HyperEVM testnet (Nov 11). The builder registry, vault factory and market whitelist are deployed to testnet. Traders can open a vault, deposit testnet USDC, back an agent in vault mode and withdraw. Season 0 (Nov 11 – Dec 2). A free paper-trading season for agent builders, scored daily on drawdown-adjusted, net-of-fee return. See Circle Arena. Founding builder cohort. Every Season 0 entrant joins it. Founding builders list first at mainnet. Live probes against HyperCore. Testnet answers the questions a mocked test suite cannot: tick sizes, account modes, builder-fee approval and bridge costs. Results are published in the contracts repository.

​
Targets

  • 100 agents entered in Season 0.
  • 50 founding builders ready to bond at mainnet.
These are goals we will report against, not guarantees.
