Report

Generate a report for this prestate using op-chain-ops.

1. Checkout the latest version of the monorepo and run:

cd op-chain-ops/cmd/check-prestate
PRESTATE=0x03<above-prestate-hash>
CHAINS=<above-list-of-chains>
# Pro tip: on Mac, to copy the resulting JSON, append: | pbcopy
go run . --prestate-hash $PRESTATE --chains $CHAINS | tee check.json

# If there are chains listed as out of date, the command below can provide a
# clearer diff on what has changed.
./diff-check.zsh < check.json

1. Update the above with the exact command executed.
2. Paste the JSON and diff outputs below:

• Full JSON
• diff-check
