on-chain rules.

no servers. no middlemen. rules live in solana programs and can't be bypassed.

sub-accounts

one vault, many agents.

each agent gets an isolated sub-account with its own budget. create, pause, close — anytime.

spending rules

max per tx. max per day.

hard limits enforced on-chain by the solana program. can't be bypassed.

whitelist

approved services only.

agents can only pay whitelisted addresses. everything else is rejected.

time rules

when they can spend.

set time windows — 09:00-17:00 UTC, no weekends. enforced on-chain.

auto top-up

never run dry.

minimum balance triggers auto-refill from the main pool. zero downtime.

multi-sig

team approvals.

large payments need multiple signatures. 2-of-3, 3-of-5. defined on-chain.

fees
0%

zero fees. every tx verifiable on solana.
