What is USD Coin?
USD Coin is a digital stablecoin that is pegged to the United States dollar and runs on the Ethereum, Stellar, Algorand, and Solana blockchains. Please note that Coinmetro only currently supports the ERC-20 version of USDC.
"USDC is issued by regulated financial institutions, backed by fully reserved assets, redeemable on a 1:1 basis for US dollars, and governed by Centre, a membership-based consortium that sets technical, policy and financial standards for stablecoins."
How to Deposit USDC Into Your Coinmetro Account
If you're depositing from another exchange, it is important to ensure they support sending funds to ETH contracts, or use a full ETH wallet as an intermediary.
Note: As Coinmetro uses smart contracts for Ethereum and ERC-20 token deposits, the amount of gas required is slightly higher than a typical transfer. To be sure that your transaction is successful, please set the transaction gas limit to 55,000 for ETH. The fee difference is minimal. If your gas limit is too low, the transaction will simply be rejected by the Ethereum network. There is no risk for loss of assets caused by a too low gas limit.
How to Withdraw USDC From Your Coinmetro Account
Important Note - To request a withdrawal, your account profile needs to be verified as well as having the funds to cover your withdrawal. The first time a withdrawal is made to a destination, the destination needs to be verified via e-mail. If you have 2-Factor Authentication enabled for withdrawals, you will be asked to input the code for each withdrawal, approved or not. We suggest enabling 2-Factor Authentication to protect your account.
Withdrawals waiting for approval can be cancelled and withdrawal status can be found by selecting the wallet on the GO! Dashboard. Approved withdrawals cannot be cancelled. If there is no Cancel button, there should be a transaction ID (TXID). This is a link to the relevant tx hash (Transaction Hash) on a blockchain explorer website.
If you are withdrawing to an external wallet such as MetaMask, please ensure that you have added USDC as a custom token on the wallet.
