@ujjwalgupta94 I'm trying to use Matic.js V3 to transfer MATIC from one wallet to other. Failing to understand the properties mentioned in config.js which I need to replace/use for the same => https://github.com/maticnetwork/matic.js/blob/master/examples/config.js
Couldn't find a document explaining the same,

Also as per your explanation between Child and Parent RPC - where you said to transfer MATIC it's fine if we just use Child RPC, but POSClient().init() method expects us to pass both Child as well as Parent property. So I'm assuming we'll have to set isParent property in client.ecr20 function to false please correct me if I'm wrong. => client.erc20(config.pos.child.erc20, false);

Any help is appreciated. Thank you for your great work 👍🏻. Let me know if I can document any of these steps to help other developers explore it the first time.

yeah you can make one of the provider as null. Take a look at matic transfer doc - https://maticnetwork.github.io/matic.js/docs/plasma/erc20/transfer/

For overview, matic is plasma token, so you will have to use plasmaClient. Here is example for transferring matic - https://github.com/maticnetwork/maticjs-plasma/blob/main/examples/erc20/transfer_matic.js

Ok, thank you for the docs.

I downloaded the maticjs-plasms repo and tried to run transfer_matic.js
This is the error I'm getting
Error: PollingBlockTracker - encountered an error while attempting to update latest block:

Also in Utils.js i tried setting parent: null in plasmaClient.init, which throws a error as Parent is a mandatory field and it expects a RPC or a HTTP/HTTPS URL.

In config.js I replaced Private Key, and User1 and User 2 addresses. These are from Matic Mumbai testnet.
Given that we don't have any txn on Parent Provider I pasted https://rpc-mumbai.matic.today in parent.rpc
Plasma.child.erc20 token provided in config is correct - https://mumbai.polygonscan.com/address/0xfe4f5145f6e09952a5ba9e956ed0c25e3fa4c7f1

Please let me know what am i doing wrong here.

Hey, this seems to be rpc issue. Could you try with any other RPC please, may be sign for a private RPC.

savannahar68 Dec 13, 2021

@ujjwalgupta94 you are right. Resolved it using a different rpc.
Thanks a lot for your help 👍🏻
