 - Specify the amount

-- Confirm transaction via MetaMask
+- Confirm transaction on your Wallet
 - The address that you use to send from, the same address will be used to receive the token on a Foreign chain
 The amount sent must be within the daily limits provided by the contracts. When the transaction is validated, the user should see the Deposit event on the Home Network (left side - POA Network). After some time, Validators submit signatures emitting SignedForDeposit event to the Foreign Network. Once the required number of signatures is reached, a Deposit event is emitted on the Foreign Network. Hence, an equivalent amount of ERC20 tokens are minted on the Foreign Network with the corresponding depost address.

 - Specify an Amount
