Description of the change

Gnosis users: this is a required update for the upcoming Pectra hardfork scheduled for 30 April 2025.

Ethereum mainnet users: it's recommended to use this release rather than v3.0.1 for the upcoming Pectra hardfork scheduled for 7 May 2025.

RPC fixes:

Previous versions of Erigon 3 have two bugs regarding handling of state sync events on Polygon chains:

• Incorrect logIndex on all state sync transaction logs
• Missing log events when using eth_getLogs with filters

A proper fix has been implemented and will be progressively rolled out in Erigon 3.1 and 3.2 (track issue here). A temporary workaround has been introduced if these issues are critical for your use-case. This requires regenerating receipts for all transactions on the chain. The procedure is as follows:

1. Shutdown Erigon and all rpcdaemon processes
2. Update binaries Erigon release
3. erigon seg rm-state-snapshots --domain=receipt --datadir <your-datadir>
4. integration stage_custom_trace --datadir <your-datadir> --chain <amoy|bor-mainnet> --bor.heimdall <heimdall-url>
   • For machines with many cores, you can add --exec.workers=<num> to improve performance (default is 7)
5. Once complete, rm -rf <your-datadir>/chaindata
6. Start Erigon
