solidity/v1.1.0 is the Ethereum mainnet release of two Solidity smart contracts supporting tBTC v1 sunsetting.

VendingMachineV2 (0xcE1F983c29f7A6C0C0dFA78C4D8Fe7bdfe026d4B) is used to exchange tBTC v1 to tBTC v2 in a 1:1 ratio during the process of tBTC v1 bridge sunsetting. The redeemer selected by the DAO based on the "TIP-027b tBTC v1: The Sunsetting" proposal will deposit tBTC v2 tokens into VendingMachineV2 so that outstanding tBTC v1 token owners can upgrade to tBTC v2 tokens. The redeemer will withdraw the tBTC v1 tokens deposited into the contract to perform tBTC v1 redemptions. The redeemer may decide to withdraw their deposited tBTC v2 at any moment in time. The amount withdrawable is lower than the amount deposited in case tBTC v1 was exchanged for tBTC v2. This contract is owned by the redeemer.

VendingMachineV3 (0x7570a2350183b4BdF7CA74faD3Fc19048E6437e6 ) is used to exchange tBTC v1 to tBTC v2 in a 1:1 ratio after the tBTC v1 bridge sunsetting is completed. Since tBTC v1 bridge will no longer work, it will not be possible to perform BTC redemption with tBTC v1 tokens. This contract allows tBTC v1 owners to upgrade to tBTC v2 without any deadline. This way, tBTC v1 tokens left on the market are always backed by Bitcoin. The governance will deposit tBTC v2 into the contract in the amount equal to tBTC v1 supply. The governance is allowed to withdraw tBTC v2 only if tBTC v2 left in this contract is enough to cover the upgrade of all tBTC v1 left on the market. This contract is owned by the governance.

The NPM package is available in the NPM registry as @keep-network/tbtc-v2@1.1.0
