# How it works

Off-ramp widget allows user to exchange their crypto currency to his country's local currency.

How it works for end users:

1. Customer selects off-ramp type (only bank transfer is supported now) and specifies the amount of crypto he wants to exchange. System displays how much local currency he will receive.
2. Customer verifies his email by entering a code sent to him.
3. Customer provides his account details such as bank account number, bank name, etc.
4. System returns a wallet address where customer should send his crypto.
5. Customer sends crypto to the provided address and provides a transaction hash to the system.
6. System checks if the transaction is received and sends local currency to the customer's account.
