SchnorrSnap

Quick Start

yarn install && yarn build:all && yarn demo:local

Example code,

In packages/example/frontend/Intro.tsx

import { initiateSchnorrSnap } from "./services/metamask"
import { SnapIdentity } from "@astrox/schnorr-adapter"
import { SignRawMessageResponse } from "@astrox/schnorr-types"

...
  const [snapIdentity, setSnapIdentity] = useState<SnapIdentity | undefined>(
    undefined,
  )

  const installSnap = useCallback(async () => {
    // you can customize initiateSchnorrSnap with your function, hooks, or service what ever
    // pass network type `mainnet`, `local`, or `nostr`
    // coinType in derived path will be different, mainnet and local will be 0, nostr will be 1237 (NIP-06)
    const installResult = await initiateSchnorrSnap("nostr")
    if (!installResult.isSnapInstalled) {
      setInstalled(false)
    } else {
      setInstalled(true)
      setSnapIdentity(await installResult.snap?.createSnapIdentity())
    }
  }, [])

  const getPublicKey = async () => {
    setPublicKey(snapIdentity?.publicKey)
  }

  const signMessage = async () => {
    const signed = await snapIdentity?.api.sign(message!)
    setSignedMessage(signed!)
  }
...

Components and install instructions

1. Download Metamask Flask and uninstall/disable old metamask

2. Go to example page or any supported page, install SchnorrSnap before run

3. Can sign message afterwards

How it works

1. Develope Metamask Flask Snap project
2. Use Secp256k1Key(Schnorr) identity inside snap
3. Get identity and signing method for web app

Use cases

1. Use Metamask as your schnorr wallet
2. Access NoStr
