These parameters are prefixed with underscore to indicate they're unused, but they remain in the function signature. Consider removing them entirely or adding a TODO comment explaining when they'll be implemented.

Suggested change

	amount: _amount,
	btcConnector: _btcConnector,
	btcAddress: _btcAddress,
	depositorEthAddress: _depositorEthAddress,

The subtitle parameter is renamed to _subtitle but never used. Since this is a breaking change to the component interface, consider removing it entirely or documenting why it's being kept.

The magic number 100000000 should be defined as a named constant (e.g., SATOSHIS_PER_BTC) to improve readability and maintainability.

Suggested change

	// Helper function to convert satoshis to BTC
	const satoshiToBtc = (satoshi: number): number => {
	return satoshi / 100000000;
	// Number of satoshis in one BTC
	const SATOSHIS_PER_BTC = 100000000;
	// Helper function to convert satoshis to BTC
	const satoshiToBtc = (satoshi: number): number => {
	return satoshi / SATOSHIS_PER_BTC;
