Hello everyone,
We have released Heimdall v0.11.0 for both Mainnet and Amoy. This release includes an important security fix (fee-coins-cap gate), activated at the Kyoto hardfork. Source code is now public - see the GitHub release:
https://github.com/0xPolygon/heimdall-v2/releases/tag/v0.11.0
Kyoto Activation Block
• Mainnet: Block 51,533,000 — activated on 2026-08-18 at 10:10:31 UTC
• Amoy: Block 42,252,000 — activated on 2026-08-06 at 08:08:46 UTC
Both networks have already passed their Kyoto activation height. Any operator still running a pre-Kyoto binary should upgrade as soon as possible.
