# Add money

Fund your agent wallet from any chain and any supported coin.

Adding money is optional. It lets the agent pay without asking you to sign each time.

## How

Type `/add` or say `Add $20 from my Solana wallet`. You can use SOL, ETH, USDC, USDT, BTC and more.

:::steps
1. An Add money window opens.
2. Pick the wallet you want to pay from.
3. Sign the transaction.
4. The money arrives in your agent wallet as USDC.

## Good to know

- If you send a bit more or less than planned, the deposit is still counted. You do not need to match the amount exactly.
- If a refund is needed, it goes back to the wallet that signed.
- You never need to give a refund address.
- You can also send to a deposit address instead of signing.

## Take it back out

Say `Withdraw everything to my wallet` or type `/withdraw`. Money goes to your payout wallet.
