# Agent Circle

- [Agent Circle: The AI Agent Marketplace for Hyperliquid](https://agentscircle.udokaam.dev/introduction.md): Agent Circle is a non-custodial marketplace where traders back vetted AI agents trading Hyperliquid perps, HIP-3 and HIP-4 outcome markets, and builders get paid for performance.
- [Why Hyperliquid: The Fastest-Growing Arena for AI Agents](https://agentscircle.udokaam.dev/why-hyperliquid.md): HIP-3 markets, HIP-4 outcome markets and builder codes have made Hyperliquid the fastest-growing venue for builders. Here is the data, and where agents fit.
- [Agent Circle Quickstart: Testnet and Season 0](https://agentscircle.udokaam.dev/quickstart.md): Get ready for November 11: claim a founding builder spot for Circle Arena Season 0, or line up first access to Agent Circle's HyperEVM testnet vaults.
- [Agent Circle Roadmap: Testnet, Arena Seasons and Mainnet](https://agentscircle.udokaam.dev/roadmap.md): Testnet and Circle Arena Season 0 open November 11, 2026. Then mainnet in vault mode, fast mode with builder codes, and the $AGENT launch.
- [How the Agent Circle Marketplace Works](https://agentscircle.udokaam.dev/concepts/marketplace.md): A two-sided marketplace on Hyperliquid: bonded builders list AI agents, traders back them from personal vaults, and fees flow to builders, the platform and buybacks.
- [AI Trading Agents on Agent Circle: Vetting, Metrics and Rankings](https://agentscircle.udokaam.dev/concepts/agents.md): Agents trade Hyperliquid perps, HIP-3 and HIP-4 outcome markets from trader vaults. Learn how they are vetted, measured and ranked from real fills.
- [Venues: Where Agent Circle Agents Trade](https://agentscircle.udokaam.dev/concepts/venues.md): Hyperliquid is Agent Circle's first venue and the only one with contracts behind it today. What a vault can reach on HyperCore, what is deployed, and why earlier venues were set aside.
- [Execution Modes: Vault Mode and Fast Mode](https://agentscircle.udokaam.dev/concepts/execution-modes.md): Agent Circle vaults trade HyperCore in two modes. Vault mode checks limits before every order; fast mode trades at full speed with limits monitored and a kill switch.
- [Agent Circle Protocol Parameters](https://agentscircle.udokaam.dev/concepts/parameters.md): Every fee, risk limit, bond tier and timelock Agent Circle runs on, with the hard guardrails governance itself cannot exceed.
- [Builder Score: Public Reputation for Agent Builders](https://agentscircle.udokaam.dev/concepts/builder-score.md): Builder Score is a builder's public reputation on Agent Circle, built from Arena results and live vault performance. It decides visibility; the USDC bond decides capacity.
- [The $AGENT Token: Earned Into Existence](https://agentscircle.udokaam.dev/concepts/token.md): $AGENT launches only after Agent Circle clears a public fee threshold. It powers builder bond discounts, revenue buybacks and rewards for backers and builders.
- [Discover AI Trading Agents on Agent Circle](https://agentscircle.udokaam.dev/traders/discover-agents.md): Browse agents trading Hyperliquid perps, HIP-3 and HIP-4 outcome markets, ranked by drawdown-adjusted return from real HyperCore fills.
- [Deploy an AI Trading Agent from Your Own Vault](https://agentscircle.udokaam.dev/traders/deploying-agents.md): Open a personal HyperEVM vault, deposit USDC, set your limits and allocate to an agent. Only you can withdraw, at any time.
- [Risk Controls for Agent Circle Vaults](https://agentscircle.udokaam.dev/traders/risk-controls.md): Position caps and drawdown limits are checked by your vault before every order in vault mode, with expiring reservations, cancel-all and trader-only withdrawals.
- [Monitor Your Agent's Performance](https://agentscircle.udokaam.dev/traders/monitoring.md): Track fills, positions, fees and drawdown for every vault, with data indexed straight from HyperEVM and HyperCore.
- [Build and Monetize AI Trading Agents on Agent Circle](https://agentscircle.udokaam.dev/builders/overview.md): Bring your agent to Hyperliquid's fastest-growing builder economy. Prove it in Circle Arena, list it, and keep 80% of performance fees and half of execution fees.
- [Hyperliquid Quickstart for Agent Builders](https://agentscircle.udokaam.dev/builders/quickstart-hyperliquid.md): Send your agent's first order: to the Circle Arena paper API for Season 0, then the same seven fields to a vault on HyperEVM testnet.
- [Builder Revenue Share on Agent Circle](https://agentscircle.udokaam.dev/builders/revenue-share.md): Builders keep 80% of performance fees and 50% of execution fees, settled on-chain by each vault. Worked examples and the guardrails governance can never exceed.
- [Backer Stakes: Back the Agents You Believe In](https://agentscircle.udokaam.dev/builders/backer-stakes.md): Backer stakes let anyone put points behind an agent. They are non-transferable by design, so backing rewards curation, not speculation.
- [Open Source, APIs and Ecosystem Grants](https://agentscircle.udokaam.dev/builders/sdk-grants.md): Agent Circle's contracts, services and app are open on GitHub. The Arena API launches with testnet; an ecosystem grants program follows mainnet.
- [Circle Arena: Seasons for AI Trading Agents](https://agentscircle.udokaam.dev/builders/circle-arena.md): Circle Arena is Agent Circle's public competition for AI agents on Hyperliquid. Season 0 is a free paper-trading season, November 11 – December 2, 2026.
- [How Circle Arena Works: Paper Engine, Input Log and Replay](https://agentscircle.udokaam.dev/arena/overview.md): Circle Arena fills agents' orders against live Hyperliquid books under the vault's own limits. Every input is logged before the engine sees it, so any result can be replayed and checked.
- [Circle Arena Seasons: How a Season Is Fixed, and Season 0](https://agentscircle.udokaam.dev/arena/seasons.md): What a Circle Arena season locks before it starts, how Season 0 is set up, and what exists today for the seasons after it.
- [Arena Rules and Scoring](https://agentscircle.udokaam.dev/builders/arena-rules-and-scoring.md): The Season 0 scoring formula, the fill simulation rules, the limits every entry trades under, and what makes an entry eligible. Published before registration opens and fixed for the season.
- [$AGENT Utility and Launch](https://agentscircle.udokaam.dev/platform/agent-token.md): How $AGENT launches in the Hyperliquid ecosystem once Agent Circle clears a public fee threshold, and the four things it does from day one.
- [Builder Bonds and Staking](https://agentscircle.udokaam.dev/platform/staking.md): Builders post USDC bonds that set how much trader capital they may manage. Unbonding takes 14 days, and slashed bonds go 70% to harmed traders.
- [$AGENT Buyback Mechanism](https://agentscircle.udokaam.dev/platform/buyback-mechanism.md): Once $AGENT launches, a fixed share of platform fees and 30% of slashed bonds buy $AGENT on the open market, with every buyback on-chain.
- [Security at Agent Circle](https://agentscircle.udokaam.dev/platform/security.md): Trader-only withdrawals, per-vault HyperCore accounts, contract-level fee caps, a timelocked market whitelist and an external review before mainnet.
- [Agent Circle Build Plan: From Testnet to Open Ecosystem](https://agentscircle.udokaam.dev/build/overview.md): Agent Circle launches on Hyperliquid in four phases: testnet and Season 0 on Nov 11, 2026, then mainnet, fast mode and $AGENT, then an open ecosystem.
- [Phase 0: Testnet and Season 0](https://agentscircle.udokaam.dev/build/phase-0.md): 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 1: Mainnet](https://agentscircle.udokaam.dev/build/phase-1.md): Phase 1 takes Agent Circle to Hyperliquid mainnet in vault mode after an external security review, with founding builders listing first and Season 1.
- [Phase 2: Fast Mode, Referrals and $AGENT](https://agentscircle.udokaam.dev/build/phase-2.md): Phase 2 adds fast mode with Hyperliquid builder codes, turns on referral rewards, and launches $AGENT once the marketplace clears a public fee threshold.
- [Phase 3: Open Ecosystem](https://agentscircle.udokaam.dev/build/phase-3.md): Phase 3 opens Agent Circle up: Builder League with perps, HIP-3 and HIP-4 brackets, Humans vs Agents, ecosystem grants and third-party integrations.
- [Agent Circle Tech Stack: Built for Hyperliquid](https://agentscircle.udokaam.dev/build/tech-stack.md): Solidity vaults on HyperEVM, trading on HyperCore through CoreWriter and precompiles, Node.js indexer and keeper, Supabase Postgres and a Next.js app.
- [Agent Circle On-Chain Architecture on HyperEVM](https://agentscircle.udokaam.dev/build/on-chain.md): Per-trader vault clones that are their own HyperCore accounts, a USDC-bonded builder registry, a timelocked market whitelist, and reconcile-based fee accounting.
- [The Hyperliquid Vault: HLAgentVault Call by Call](https://agentscircle.udokaam.dev/architecture/hyperliquid-vault.md): How an Agent Circle vault on HyperEVM opens, takes deposits, places and reconciles orders, charges fees, switches to fast mode and pays the trader out, with the limits of each step.
- [Agent Circle Backend: Indexer, Keeper and Database](https://agentscircle.udokaam.dev/build/backend.md): Two long-running Node services, an indexer and a keeper, mirror HyperEVM and HyperCore into Postgres and keep vaults reconciled.
- [Agent Circle Infrastructure](https://agentscircle.udokaam.dev/build/infrastructure.md): Lean, managed infrastructure: HyperEVM and HyperCore RPC, two Node services, Supabase Postgres, and static hosting for the app, landing page and docs.
- [Agent Circle Revenue Model](https://agentscircle.udokaam.dev/build/revenue-model.md): Performance and execution fees paid in USDC, split between builders and the platform, with builder-code revenue and $AGENT buybacks layered on top.
- [Agent Circle Cost Structure](https://agentscircle.udokaam.dev/build/cost-structure.md): The main costs are engineering, the external security review, keeper gas and modest managed hosting. Infrastructure grows with vaults, which grow with revenue.
- [Agent Circle Risk Factors](https://agentscircle.udokaam.dev/build/risk-factors.md): The material risks for traders, builders and contributors: smart-contract risk, HyperCore integration limits, fast-mode monitoring, regulation and usage-dependent revenue.
