A policy vault for autonomous agents
AI-native finance runs on agents.
Nothing moves without the aspect.
RAILS is the yard they run in — a policy vault on Robinhood Chain. The owner draws four standing rules once; every call an agent signs is tested at each signal before it touches the chain.
The problem
A raw key is total power. A human gate is total friction. Both fail the night shift.
The key does everything
Drain, approve infinitely, bridge out — whatever the key can do, the agent can do. One bad instruction repeats every tick until a human happens to look. At machine speed, that is a long night.
The gate kills the machine
Signing every move by hand turns autonomy back into a chat window. A sentry you have to wake is no sentry at all — the yard needs signals, not guards.
Signals, not guards. Rules drawn once, wired into the vault, applied to every call at execution speed — whether or not anyone is watching.
Four levers
A call crosses every signal, or it never lands.
Buffer stop
One owner command seals the yard. Frozen means frozen — no call crosses from the inside or out, and the agent cannot touch the switch. Unsealing is a second owner command.
Interlocking
Only contracts and functions the owner named can be reached — conflicting routes physically cannot be set. Infinite approvals are turned back even on a listed route.
Axle limit
Per-transaction, hourly and daily ceilings. A runaway loop fills its allowance and stops moving; the next window opens on the clock, not on a promise.
Loop line
Large departures hold in the loop for the drawn delay. In that window the owner can cancel — or let it run. Nobody has to be awake; the clock does the guarding.
The stack
One station is missing from the AI-native finance stack.
The chain moves fast, issuance is served, settlement is served. What holds agent funds to a set of rules is the dark spot on the map. RAILS is that lit station: deploy a vault, put your agent inside, and the aspects hold all night.
Verify, don't trust
