# Outflow policy

Your outflow limit caps the total value that can leave the server-wallet in a rolling 24-hour window. MetaMask tracks outflows automatically and requests 2-factor authentication approval when a transaction would exceed the limit.

Outflow limits apply in **Guard Mode (Recommended)** when using server-wallet. See [Trading modes](/agent-wallet/reference/trading-modes/) for how Guard Mode enforces this policy alongside other guardrails.

## Setting your outflow limit[​](#setting-your-outflow-limit "Direct link to Setting your outflow limit")

You're prompted to set your outflow limit on your first transaction, or whenever a transaction would exceed your current limit. When you set your 24-hour outflow limit, it counts the transaction you're approving now plus all transactions in the rolling window.

## How outflow is calculated[​](#how-outflow-is-calculated "Direct link to How outflow is calculated")

Before signing, MetaMask simulates the transaction value and adds that value to your 24-hour total once the transaction is confirmed (submitted successfully).

For example, if you swap 10 USDC to ETH and later swap the ETH to DAI, this counts as a $10 outflow for USDC to ETH and another $10 for ETH to DAI.

You'll receive a 2-factor authentication request when the transaction exceeds your 24-hour outflow limit.

## What's included[​](#whats-included "Direct link to What's included")

Our transaction simulation engine analyzes token outflow from your account and estimates the volume in USD. This includes token transfers, swaps, and deposits (for example, to Uniswap, Polymarket, or Hyperliquid).

## Limitations[​](#limitations "Direct link to Limitations")

Outflow tracking can be imprecise if transactions are not submitted through our backend.

When an outflow can't be tracked reliably, such as when a transaction can't be simulated, fall back on your allowlists.

Signatures (for example, Permit2) are not included in the outflow calculation as of now.
