What is posRootChainManager.processReceivedMessage equivalent in v3? #312

Hi, in v2 we called this method:

    const tx = await maticPOSClient.posRootChainManager.processReceivedMessage(
      rootTunnelAddress,
      txHash,
      {
        from,
        encodeAbi: true
      }
    )

What is the equivalent of this method in v3?

Having a hard time finding it in docs

Thanks!

I was able to generate the proof, just ensure that you have latest version of maticjs 3.2.0 . Here is code -

const matic = new FxPortalClient();


    await matic.init({
        log: true,
        network: 'mainnet',
        version: 'v1',
        parent: {
            provider: new HDWalletProvider(privateKey, rootRPC),
            defaultConfig: {
                from
            }
        },
        child: {
            provider: new HDWalletProvider(privateKey, maticRPC),
            defaultConfig: {
                from
            }
        },
        erc20: {
            rootTunnel: '0x7A08f1409E5D3e9Bc49063aA4009fB4BBC8777C3',
        }
    });

const rootTokenErc20 = matic.erc20(…

processReceivedMessage is part of fx-portal, so it's not in matic.js v3. We have created seperate repo for support of fxportal .

The equivalent api you can use is - withdrawExit.

const fxPortalClient = new FxPortalClient();

await fxPortalClient.init({
    network: 'testnet',
    version: 'mumbai',
    parent: {
        provider: new HDWalletProvider(privateKey, rootRPC),
        defaultConfig: {
            from
        }
    },
    child: {
        provider: new HDWalletProvider(privateKey, childRPC),
        defaultConfig: {
            from
        }
    }
});

const result = await erc20.withdrawExit(<burn tx hash>);
const txHash = await result.getTransactionHash();
const receipt = await result.getReceipt();

Here is doc - https://github.com/fx-portal/maticjs-fxportal#withdrawexit

for passing rootTunnel Address, you can pass value in init method -

const fxPortalClient = new FxPortalClient();

await fxPortalClient.init({
    network: 'testnet',
    version: 'mumbai',
    parent: {
        provider: new HDWalletProvider(privateKey, rootRPC),
        defaultConfig: {
            from
        }
    },
    child: {
        provider: new HDWalletProvider(privateKey, childRPC),
        defaultConfig: {
            from
        }
    },
    erc20:{
        rootTunnel : <root tunnel address>,
        childTunnel: <child tunnel address> 
   }
});

@ujjwalguptaofficial in your example, where does erc20 come from? There was no concept of erc20 in v2 for .posRootChainManager.processReceivedMessage(...)

Do you know what the error RLPReader: ITEM_NOT_LIST means here?

We are trying to upgrade maticjs from v2 because we started seeing this invalid remainder decode error with the current v2 version we are using when calling maticPOSClient.posRootChainManager.processReceivedMessage(l1FxBaseRootTunnel, txHash). This error started occurring this week and it's prevent L2 txs to be exited to L1

I think I made some progress but ran into a strange error; invalid opcode: opcode 0xf9 not defined. The tx is populated but this is thrown by the rpc provider when broadcasting tx.

Any help is appreciated. Thanks

I was able to generate the proof, just ensure that you have latest version of maticjs 3.2.0 . Here is code -

const matic = new FxPortalClient();


    await matic.init({
        log: true,
        network: 'mainnet',
        version: 'v1',
        parent: {
            provider: new HDWalletProvider(privateKey, rootRPC),
            defaultConfig: {
                from
            }
        },
        child: {
            provider: new HDWalletProvider(privateKey, maticRPC),
            defaultConfig: {
                from
            }
        },
        erc20: {
            rootTunnel: '0x7A08f1409E5D3e9Bc49063aA4009fB4BBC8777C3',
        }
    });

const rootTokenErc20 = matic.erc20('0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174', true);

setProofApi("https://apis.matic.network");
 const result = await rootTokenErc20.withdrawExitFaster(
        '0x70bb6dbee84bd4ef1cd1891c666733d0803d81ac762ff7fdc4726e4525c1e23b', {
        returnTransaction: true
    }
);

return console.log('result', result);

I have tested using returnTransaction: true, just remove that and you will be able to send the transaction.
