As we move towards a omnichain future, your dApps users can onboard from any blockchain possible
That's why we are building this
Now your user can sign in from any blockchain and prove their ownership to your servers
In frontend, you would want to sign a message from the user's wallet
Generate Message
import { prepareMessage, Blockchain } from "siwac"
const message = prepareMessage({
domain: "DOMAIN",
address: "ADDRESS",
blockchain: Blockchain.APTOS,
message: "ANY MESSAGE",
uri: "FULL_URI",
version: '1',
blockchainId: '1'
})sign the generated message from user and send it to server for verification
In backend, you would want to verify the signed message and probably generate access tokens for the user
Verify Signature Details like address, timestamp etc are directly unpacked from the message string itself through parser
import { verifyMessage } from "siwac"
const verified = await verifyMessage(message, signature)
if(verified) {
// your logic
}Verify Signature and Generate JWT
import { verifyMessageAndGenerateJWT } from "siwac"
const token = await verifyMessageAndGenerateJWT(message, signature, "YOUR_JWT_SECRET", "30m" // OR 8h)
// token = { accessToken: string, expiresIn: string }Now we also need to verify the JWT generated to grant user's access to some gated data
Verify JWT
import { verifyJwtToken } from "siwac"
const verified = await verifyJwtToken("ACCESS_TOKEN", "TEST_SECRET")
if(verified) {
// your logic
}
