What is Leash

Leash sits between an AI agent and its wallet on Robinhood Chain. Before the agent signs anything, it asks Leash. Leash checks the action against your rules and answers allowed, blocked, or ask the owner.

The agent never holds more freedom than you gave it, even if its own logic goes wrong or someone tricks it with a prompt.

How a check runs

Checks run in this order. The first one that fails decides the answer.

1. Kill switch is off.
2. The agent isn't paused.
3. The asset is on the allowed list.
4. The token isn't under 24 hours old, if that rule is on.
5. The amount is within the per-action limit.
6. The amount fits in what's left of the daily budget. Sells and withdrawals skip this.
7. It's within allowed hours, if that rule is on.
8. If the amount is above your "ask me" level, it waits for your approval. Otherwise it's allowed.

Connect an agent

Call check before every transaction and only sign when the answer is allowed.

import { Leash } from "@leash/sdk";

const leash = new Leash({ agentId: "swing-bot" });

const verdict = await leash.check({
  action: "buy",
  symbol: "NVDA",
  amountUsd: 45
});

if (verdict.allowed) await wallet.send(tx);
// verdict.reason → "Above $40 — waiting for you"

Illustrative only — the package is not published. This site's server answers the same question at POST /api/check.

Approvals

An action above your "ask me" amount waits in the dashboard. Approve it and it goes through, as long as the daily budget still has room. Decline it, or leave it, and it doesn't happen.

Kill switch

One switch blocks every agent on its next check. Nothing already signed is reversed, so act fast when something looks off.
