Release v1.3.0: Taiga Hardfork (MAINNET)

on GitHub

The Taiga hardfork for Blast Mainnet activates on Wednesday, May 7, 2025 at 10:05:11 AM UTC (1746612311). This is the same timestamp that the Prague upgrade activates on Ethereum Mainnet. Node operators must upgrade both blast-geth and blast-op-node.

⚠️ Don’t forget to update your rollup.json when upgrading. Alternatively, if you’re using environment variables or CLI flags:

Environment Variable:

OP_NODE_OVERRIDE_TAIGA=1746612311

CLI Argument:

--override.taiga=1746612311

Changelog:

• Support for Prague’s L1 Header format, including the new RequestHash field. Also adds support for the new SetCodeTx type, but does not activate it for use on Blast.
• MaxSequencerDrift is now a fixed constant of 1800 seconds (30 minutes) instead of a configurablerollup.json parameter. (You may leave the old parameter in rollup.json; it will be ignored.)
