+# Threshold Go Electrum
+
+Maintained fork of [keep-network/go-electrum](https://github.com/keep-network/go-electrum),
+which extends checksum0/go-electrum with WebSocket support and fixes used by keep-core.
+The initial Threshold fork preserves upstream commit
+`6038cb594daa66c69ea0482fa849b165b115c97b` without runtime changes.
+
+The module retains `github.com/checksum0/go-electrum` as its declared path so existing
+Go imports and type identities remain compatible. Consumers select this fork in
+`go.mod`:
+
+```go
+replace github.com/checksum0/go-electrum => github.com/threshold-network/go-electrum v0.0.0-20240206170935-6038cb594daa
+```
+
+Run `go test ./...` and `go vet ./...` when contributing. The upstream MIT license
+is retained. New fixes belong in this Threshold repository.

 # go-electrum [![GoDoc](https://godoc.org/github.com/checksum0/go-electrum?status.svg)](https://godoc.org/github.com/checksum0/go-electrum)
 A pure Go [Electrum](https://electrum.org/) bitcoin library supporting the latest [ElectrumX](https://github.com/kyuupichan/electrumx) protocol versions.  
 This makes it easy to write cryptocurrencies based services in a trustless fashion using Go without having to run a full node.
