# Liquid BTC on Oasis Sapphire

This project allows you to deposit and withdraw Bitcoin on the Oasis Sapphire

confidential blockchain. Deposits of specific sizes (powers of 2) can be

converted into [LiquidBTC](token/contracts/LiquidBTC.sol), an ERC-20 compatible

token, which can in return be exchanged for real BTC.

It uses an on-chain Bitcoin SPV light-client to verify deposits have been made

to addresses generated by the [BTCDeposit](token/contracts/BTCDeposit.sol)

contract. To redeem the underlying BTC a deposit can be 'burned' which reveals

the secret key and address to the holder, meaning 'un-burned' BTC deposits can

be freely traded or converted to & from LiquidBTC tokens because the secret key

can't leak without it being evident.
