Getting started with the ElectrumSV SDK

The SDK simplifies setting up a local regtest node on any platform and provides commands for starting, stopping, and funding a wallet.

#3about 4 minutes

Running a local merchant API instance

The SDK automates the setup of a local merchant API instance, which is a standard service for end-to-end acceptance testing.

#4about 7 minutes

Simulating a blockchain reorg for testing

Use Python scripts with the SDK as a library to create a fork between two nodes and simulate a transaction reorg.

#5about 2 minutes

Using a regtest environment for application benchmarking

A regtest environment removes network latency, allowing for repeatable performance tests and easier debugging of correctness issues under heavy load.
