Struct TransactionAdapter

Source 
pub struct TransactionAdapter;
Expand description

Responsible for doing the conversion between Bitcoin transaction and Substrate extrinsic.

§NOTE

To convert the bitcoin transactions to substrate extrinsics, the recommended practice in Substrate is to leverage a runtime api for forkless upgrade such that the client (node binary) does not have to be upgraded when the Pallet/Runtime call is changed within the runtime. However, we don’t need this convenience as the pallet-bitcoin is designed to be super stable with one and only one call. Hence we choose to pull in the pallet-bitcoin dependency directly for saving the cost of calling a runtime api.

Using a trait also allows not to introduce the subcoin_runtime and pallet_bitcoin deps when the adapter is needed in other crates, making the compilation faster.
