# SeedSigner Recovery Information
|
|
|
|
SeedSigner creates extended public keys for the coordinator following [slip-0132](https://github.com/satoshilabs/slips/blob/master/slip-0132.md) to encode the extended public key. SeedSigner supports native and nested segwit for single sig and multisig.
|
|
|
|
Derivation paths for standard script types for mainnet:
|
|
|
|
- Single Sig
|
|
- Native Segwit
|
|
- Derivation Path: m/84'/0'/0'
|
|
- Script Type: P2WPKH
|
|
- Public Key Encoding: 0x04b24746 - zpub
|
|
- Nested Segwit
|
|
- Derivation Path: m/49'/0'/0'
|
|
- Script Type: P2WPKH in P2SH
|
|
- Public Key Encoding: 0x049d7cb2 - ypub
|
|
- Multisig
|
|
- Native Segwit
|
|
- Derivation Path: m/48'/0'/0'/2'
|
|
- Script Type: P2WSH
|
|
- Public Key Encoding: 0x02aa7ed3 - Zpub
|
|
- Nested Segwit
|
|
- Derivation Path: m/48'/0'/0'/1'
|
|
- Script Type: P2WSH in P2SH
|
|
- Public Key Encoding: 0x0295b43f - Ypub
|
|
|
|
Custom derivation paths are also optional when generating an xpub from SeedSigner. The Public Key Encodings are detected based on the derivation path configured. The `embit` bitcoin library does this detection and is documented [here](https://github.com/diybitcoinhardware/embit/blob/master/docs/api/bip32.md#detect_version). For a video explanation of these standards see a presentation by Stepan of `embit` on this topic: https://youtube.com/watch?v=JCaC5DG2HTM

Changing the network settings from main to test in SeedSigner will change the public key encoding and derivation path following [slip-0132](https://github.com/satoshilabs/slips/blob/master/slip-0132.md) standards.
