How to Deposit MATIC Into Your Coinmetro Account
If you're depositing from another exchange, it is important to ensure they support sending funds to ETH contracts, or using 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 of loss of assets caused by a too-low gas limit.

How to Withdraw MATIC 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 canceled and withdrawal status can be found by selecting the wallet on the GO! Dashboard. Approved withdrawals cannot be canceled. 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.
Important note - MATIC is an ERC-20 token supported on the Ethereum blockchain, so please ensure you withdraw to an ERC-20 wallet address. If you are withdrawing to an external wallet such as MetaMask, please ensure that you have added MATIC as a custom token on the wallet.
