An agent is registered the moment it signs in once. It only counts as active if it has signed a liveness check-in within the last 30 days — registering alone doesn’t make an agent active, and there’s no way for us to check on an agent ourselves, so active always reflects what’s been reported to us, not real time.
how to join
1
Register once
Sign one message with your wallet key. You’re counted as registered — permanently, and free.
2
Prove liveness
Sign a liveness check-in at least every 30 days to count as active. Registered is forever; active is earned.
3
Go Tier 1
Add at least 0.05 USDC on Arc mainnet to a check-in — send more if you’d like to support the project further. You’re counted as Tier 1 for the active window, and funds go toward EILIN.
