From wallet to
a governed agent.
LeashFi gives an AI agent a controlled way to move funds and call trading tools—without giving it unrestricted authority.
02REGISTER
Register an agent
Give the agent a name and add its public EVM address. Your agent keeps its own signer; LeashFi never needs its private key.
03PROTECT
Set policy guardrails
Configure daily and per-recipient caps, allowed recipients, assets, symbols, order types, and the approval threshold for sensitive actions.
04AUTHORIZE
Create an API key
Create a key in Settings, copy it once, and keep it on your server. Use it through the SDK or send it as x-api-key to the LeashFi API.
05EXECUTE
Choose your operating rail
Use Chain payments for policy-enforced onchain transfers, or route Robinhood Agentic Trading writes through LeashFi for policy evaluation before execution.
06REVIEW
Monitor and approve
Track activity, exposure, blocked requests, and approvals from the dashboard. High-value actions wait for the owner; expired or unknown writes fail closed.
Why LeashFi exists
Everything you need.
Nothing you don't.
Onchain payment enforcement and offchain trading controls share one policy vocabulary—without asking agents to hold unrestricted authority.
01 · ONCHAIN
Onchain payment vault
Recipient rules, asset limits, and caps execute in a Solidity vault on Robinhood Chain. The SDK cannot bypass a reverted policy check.

02 · GRANULAR
Asset and order caps
Limit USDG recipients, symbols, order types, options, crypto, per-order notional, and daily trading exposure independently.
03 · 5:00 WINDOW
Human review before execution
High-value payments and live orders pause for explicit approval. Expired or unknown write tools fail closed.

Blocked recipient never reaches the vault
Two rails · one policy model
Pay onchain.
Trade through MCP.
LeashFi wraps an existing EVM signer for Robinhood Chain and places a fail-closed policy gateway in front of mutating Robinhood Agentic Trading tools.

One review queue.
Two execution rails.
Above the threshold? The action pauses. Approve a Robinhood Chain payment or a Trading MCP order from the same policy-aware queue.
01LeashFi evaluates intent — amount, asset, symbol, recipient, and policy version.
02Approval channel fires — agent, rail, amount, recipient, and reason.
03Runner waits — until a reviewer decides or the request expires.
04Vault or MCP executes — only after the approved request is revalidated.
