Polkadot, Tron message signing

[AndreiMitrea]

Hey. I am trying to implement a flow (that works with web3modal for EVM chains) with Wallet Connect for Polkadot and Tron :

1. Generate a message
2. Prompt the user to sign the message
3. Verify that the correct address was used for the signature.

For Polkadot it works with Nova wallet, but with Trust Wallet I have the following error when the user signs the message:
{"code":5201,"message":"Unknown method(s) requested"}

Code is similar with:

            params = {
                chainId: 'polkadot:91b171bb158e2d3848fa23a9f1c25182',
                topic: wcSession.topic,
                request: {
                    method: 'polkadot_signMessage',
                    params: {
                        address,
                        message,
                    },
                },
            } as EngineTypes.RequestParams;
            
            ({ signature } = await client.request<{ signature: string }>(params));

For Tron, I am able to sign the message with Trust Wallet, but the address returned by tronWeb.trx.verifyMessageV2 at the verification step is different to the one used:

            const tronWeb = new TronWeb({
                fullHost: 'https://api.trongrid.io',
            });

            const verifiedAddress = await tronWeb.trx.verifyMessageV2(verificationMessage, signature);

Please let me know if you have any advice. Thank you!

Thanks for reporting, we'll try to communicate this to Trust

Could you share your configuration?

Also could you test it here: https://react-app.walletconnect.com/

@glitch-txs It seems like you haven't figured out the problem yet? It is that the signature of connecting TRON network with Trust Wallet cannot be verified.

const message = "This is a message to be signed for Tron";

try {
    const result = await client!.request<{ signature: string }>({
    chainId,
    topic: session!.topic,
    request: {
        method: DEFAULT_TRON_METHODS.TRON_SIGN_MESSAGE,
        params: {
        address,
        message,
        },
    },
    });

    return {
    method: DEFAULT_TRON_METHODS.TRON_SIGN_MESSAGE,
    address,
    valid: true,
    result: result.signature,
    };

Your valid is fixed to true.

Using tronWeb for verification:

const verifiedAddress = await tronWeb.trx.verifyMessageV2(message, result.signature);

The verified address obtained is not the wallet address

Do you know if this issue does NOT happen with other wallet?

[liubin595338764]

@glitch-txs Trust is a wallet with a relatively wide user base, I don't have any other Tron wallets.

[glitch-txs]

We'll look into this + I've sent this to Trust as well

[liubin595338764]

[Emergency] @glitch-txs I have also encountered the same problem, and I am using @walletconnect/universal-provider, @web3modal/standalone

const result = await this.provider.client!.request<{
  signature: string
}>({
  topic: this.session?.topic,
  chainId: this.chains[0],
  request: {
    method: 'tron_signMessage',
    params: { message, address },
  },
})

"@walletconnect/universal-provider": "2.10.0",
"@web3modal/standalone": "2.4.3",
"tronweb": "5.3.1",

trust wallet: 10.6(883)
chrome: 120.0.6099.129

I can obtain the signature result normally, but TronWeb.Trx.verifyMessageV2(msg, signature) does not return the wallet's address.

@glitch-txs @Sadeghi1017 Is there any progress?

I also encountered a similar problem with signature verification. Is there a solution?
