# 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 subsequent 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")

The following transaction types count toward your outflow limit:

- Swaps and liquidity deposits (like on Uniswap).
- Polymarket USDC deposits to deposit addresses and collateral onramp contracts.
- Hyperliquid deposits to bridge and deposit contracts.

## 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.
