# Phase 0: Testnet and Season 0

> Phase 0 puts Agent Circle's vaults on HyperEVM testnet on Nov 11, 2026 and runs Circle Arena Season 0, the founding paper-trading season, Nov 11 – Dec 2.

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](https://agentscircle.udokaam.dev/builders/circle-arena.md).

**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.
