@akyo8 what is the error here? Are you sure that the zkWallet has an ERC20 token balance enough to cover the transfer amount?

[akyo8]

@dutterbutter It would be great if you can give me a brief instruction to let me know how can I update ERC20 token balance in zkWallet. Do I need any specific deployment for it?

[dutterbutter]

Hey @akyo8 please refer to the documentation that outlines how to interact with accounts and make L1-L2 transactions.

You need to ensure your wallet has appropriate funds before being able to deploy, send, bridge etc.

[akyo8]

@dutterbutter thanks for your update. here is my quick question.
Is subgraph support zkSync era testnet? I can see zkSync era but not able to see testnet mark. So I want to make sure if zkSync era testnet supported for subgraph. And if we want to implmeent subgraph for testnet what could be ideal solution

[dutterbutter]

TheGraph subgraphs are not yet supported on zkSync Era testnet but we are working on inclusion.

[uF4No]

actually subgraphs are supported, just that the graph-cli does not fully support zkSync yet (we're working on it!) so you have to create them manually for now. We'll have the fix for the graph cli very soon.

[akyo8]

Thanks for your reply. So when do you think if it support zkSync era testnet. It is very important for us for launch schedule

[uF4No]

In the next release after this PR is merged

[uF4No]

@akyo8 theGraph cli version 0.55.0 now supports both zkSync Era testnet and mainnet
