Describe the bug

Anvil throws an error, when it's sent valid blob transactions.

I've written a repo and test to highlight the bug here: https://github.com/iAmMichaelConnor/demo-anvil-blob-issue
Details of how to build the repo and run the failing test are in the README.

The test successfully runs when using a "Hardhat Network Node", but not when using an Anvil node. The fact that viem, cKzg, a hardhat node, and a Solidity contract compiled via forge, all work together to result in a passing test, suggests to me that it's Anvil that's likely got a bug interpreting blob txs.

When submitting a blob tx, Anvil says:

InvalidParamsRpcError: Invalid parameters were provided to the RPC method.
[1]     Double check you have provided the correct parameters.

Details of the test:

The test seeks to submit a blob transaction. Using viem and cKzg, I construct a valid blob transaction and send it via viem's sendRawTransaction() method. Using sendRawTransaction ensures a Hardhat node can understand the blobby tx format. I've not been able to get Anvil to correctly interpret the data, regardless of how I send the tx. A Solidity contract - compiled via forge -- then accepts the blob and stores its versionedHash. A second tx then verifies thte kzg proof.
This test fails when using Anvil.

The failing test is triggered via:

yarn test:anvil

whereas the passing test is triggered via:

yarn test:hardhat

Thanks for reading! :)

Hi Michael, thanks for the report and the detailed repro!

this has since been fixed

but I had to add timeouts to bypass receipt error

Amazing thanks! I've just validated that updating anvil and running the test successfully accepts a blob tx.
And then your suggestion to add a timeout fixed a new error of not waiting long enough before querying for a receipt.
