@Mixnosha Version 0.3.2 does not work with geth: 1.13, you need to downgrade to 1.12.0. We are currently migrating to the latest version of geth, so the new version should be released soon. The go.mod should look like this:

module l2

Also WebSocket connections are not allowed on testnet.

Also WebSocket connections are not allowed on testnet.

which means i cannot subscribe to contract events via ws connections?

Correct. On testnet node is overloaded with traffic and listening on events is not possible.

[smickovskid]

Hey @danijelTxFusion do we have an ETA on this ? Can we perhaps use some branch that is in development ?

[danijelTxFusion]

It should be done in 2 days.

[danijelTxFusion]

Fixed in v0.4.0.
