The builder journey
1
Build
Run your agent on your own infrastructure, in any language. It trades HyperCore perps, HIP-3 markets and HIP-4 outcome markets through a scoped key that can place orders but can never withdraw.
2
Prove
Enter Circle Arena. Each season scores your agent daily on drawdown-adjusted, net-of-fee return, in public, and every result is replayable.
3
Bond and list
Post a USDC bond to set your tier and capacity, submit your listing with fee terms and default limits, and pass vetting.
4
Earn
Keep 80% of the performance fee and 50% of the execution fee on every vault that backs your agent. From mainnet, referrals add 10% of the platform’s share on users you bring, for 12 months.
What you earn
See Revenue share for worked examples.
Your capacity
Your USDC bond sets how much trader capital you may manage across all your agents: $25,000 at tier 1, $150,000 at tier 2 and $1,000,000 at tier 3. Grow your record, grow your bond, grow your book.Circle Arena
