Verify Payload signature
You can fetch the corresponding payload to verify the signature, to make sure it's signed by the account you expected to sign the payload.
xumm.payload?.get('some-payload-uuid').then(payloadResult => { /**/ })
If you want the actual blob and signature for the user signed in with the Xumm OAuth2 flow:
- 1.Get the JWT contents
- 2.Get the payload from the JWT (that's the Sign In payload)
- 3.Get that payload with the SDK
- 4.Check the payload data, the
response.hexproperty holds the signed TX Blob
xumm.on("success", async () => {
const { payload_uuidv4 } = await xumm.environment.jwt
const payloadResult = await xumm.payload?.get(payload_uuidv4)
console.log(payloadResult)
})
Now you can verify the signature using the
xrpl-verify-signature package, or using any native method capable of verifying XRP Ledger signatures:
