# Crypto Deposits

The **Deposits → Crypto** tab lets you swap USDC or USDT from other chains (or networks) into USDC on Base, deposited directly to your Safe wallet.

***

## Supported Deposit Assets

| Asset | Networks                                                                                |
| ----- | --------------------------------------------------------------------------------------- |
| USDC  | Ethereum, Tron, Polygon, Arbitrum, Optimism, Solana (not Base — that's the destination) |
| USDT  | Ethereum, Tron, Polygon, Solana                                                         |

## How It Works

1. **Select the asset and network** you want to send from
2. **Enter the amount** — a fixed-rate quote is generated instantly
3. **Review the quote** — rate locked for the duration shown
4. **Confirm** — a unique deposit address is generated for this swap
5. **Send** the exact asset and amount to the deposit address
6. The platform converts and delivers USDC on Base to your wallet automatically

***

## Fixed-Rate Quotes

Quotes are fixed-rate — the amount of USDC you receive is guaranteed at the time you confirm, regardless of market movement during the transfer window.

***

## Settlement Time

Most crypto swaps settle within **5–30 minutes** depending on the source chain's confirmation speed.

***

## Notes

* Send the **exact amount** shown — underpayment will result in a partial or refunded swap
* Each deposit address is **single-use** — generate a new one for each swap
* Do not send unsupported assets to a deposit address
