# Taproot
|
||||
|
||||
A simple keyspend example that is possible with the current API is below.
|
||||
|
||||
## Current state of taproot support
|
||||
|
||||
- [x] segwit v1 address support via bech32m
|
||||
- [x] segwit v1 sighash calculation on Transaction class
|
||||
|
||||
## TODO
|
||||
|
||||
- [ ] p2tr payment API to make script spends easier
|
||||
- [ ] Support within the Psbt class
|
||||
|
||||
## Example
|
||||
|
||||
### Requirements
|
||||
- npm dependencies
|
||||
- bitcoinjs-lib v6.x.x
|
||||
- bip32 v3.x.x
|
||||
- tiny-secp256k1 v2.x.x
|
||||
- regtest-client vx.x.x
|
||||
- local regtest-server docker container running
|
||||
- `docker run -d -p 8080:8080 junderw/bitcoinjs-regtest-server`
|
||||
- node >= v14
