FAQ

Building the client programs manually​

By default, the build.rs in the bin/host crate will rebuild the client programs every time they are modified. To manually build the client programs, you can run these commands (ake sure you have the SP1 toolchain installed):

cd ./bin/client-eth
cargo prove build --ignore-rust-version

To build the Optimism client ELF program:

cd ./bin/client-op
cargo prove build --ignore-rust-version

What are good testing blocks​

A good small block to test on for Ethereum mainnet is: 20526624.

State root mismatch​

This issue can be caused using an RPC provider that returns incorrect results from the eth_getProof endpoint. We have empirically observed such issues with many RPC providers. We recommend using Alchemy.
