💰How to sell wETH and wBTC

First you need to import the account into any convenient wallet, for the example - MetaMask.

Go to the application, go to the wallet, then copy the address of the private key.

Go to MetaMask, and paste the copied private key into the opened field.

Next, you need to enter MetaMask's internal browser, and in the search bar we insert the address https://app.uniswap.org/swap. On the page that opens, connect our MetaMask wallet.

After binding the wallet, select the token we want to exchange for Matic. If ETH/BTC tokens are not shown in the list, you can find them by the contract address

ETH: 0x7ceB23fD6bC0adD59E62ac25578270cFf1b9f619

BTC: 0x1BFD67037B42Cf73acF2047067bd4F2C47D9BfD6

When exchanging we can see the preliminary amount of exchange, click "Exchange" and confirm the transaction. It is recommended to leave from 0.1 Matic to pay for the transaction.

Done! Now you can send Matic to the exchange or leave it on TraceWallet!
