Summary

Katana mainnet op-reth was stuck at block 63,589 (one block before Isthmus hardfork at 63,590) with "Unsupported fork" errors. Root cause: genesis.json was missing pragueTime and osakaTime fork activation timestamps.

Per OP Upgrade 15, custom-genesis OP chains require pragueTime == isthmusTime so op-reth can activate Prague/Isthmus EVM rules together.

Changes

  • Added "pragueTime": 1746806401 (matches isthmusTime) to genesis.json
  • Added "osakaTime": 1773066601 (upcoming Jovian fork) to genesis.json

Verification

  • ./update.sh verification: clean ✓
  • Regenerated katana-mainnet-op-reth-*-trace.yml configs reference the updated genesis ✓
  • Gitlink unchanged ✓

Deployment notes

  • Wiped datadir required on re-deploy (fork timestamps only take effect on fresh chain init)
  • This unblocks Isthmus hardfork activation on katana
