Ethereum and Bitcoin testnet

This is the case where you want to use the SDK to interact with the tBTC bridge on Ethereum and Bitcoin testnet.

The SDK addresses it by exposing the TBTC.initializeSepolia function. That function:

• Takes an Ethers signer or provider as a parameter and uses it to interact with tBTC contracts deployed on Ethereum Sepolia

• Automatically configures an Electrum Bitcoin client to communicate with the Bitcoin testnet (communication is done through a set of pre-configured Electrum servers)

The usage of this function is exactly the same as for the previous TBTC.initializeMainnet function.
