⚠️Important Notes

1. Supported Stablecoin Deposits

Backpack Exchange only supports native stablecoin deposits on their respective networks. Depositing the wrong version of a stablecoin may result in your funds not being credited.

Example: Optimism Network

On the Optimism network, Backpack only supports deposits of USDT0 with the contract address:

0x01bFF41798a0BcF287b996046Ca68b395DbC1071

We do not support deposits of USDT with the contract address:

0x94b008aA00579c1307B0EF2c499aD98a8ce58e58

If you deposit USDT (not USDT0) on Optimism, the funds will not be credited to your Backpack account.

Note: Backpack Exchange currently supports only native USDC on each supported network. Bridged or wrapped versions of USDC (such as USDC.e) are not supported. Depositing these versions may result in loss of funds or a lengthy recovery process, if recovery is possible.

2. How to Avoid Deposit Errors

Before making a transfer:

1. Verify the deposit address and network carefully

2. Read all notices and warnings displayed on the deposit page

3. Contact our official support team if you're unsure which network or token to use

Incorrect deposits may result in:

• ⚠️ Permanent loss of funds, or
