Chang #1 hard fork successfully occurred 1st September 2024 on Cardano Mainnet.
This page is an attestation of readiness reported at that time, which was used by the hard fork working group to make the recommendation to hard fork.
Please note that the evidence and attestations below are no longer up to date, further releases or versions could now be available - please check with the provider of any tool, product or service prior to use.
The following information was reviewed by the hard fork working group and seen as sufficient evidence to recommend enacting the Chang #1 hard fork on Mainnet
The hardfork working group met on 2024-08-28 to discuss the Go / No Decision, the group unanimously agreed to proceed with the hardfork mainnet on 1st September.
The hardfork action was subsequently signed by the genesis keys and submitted to chain: see transaction via cardanoscan.
By Stake, over 92% of SPOs on 9.1.0 - the desired hard fork threshold for SPOs has been reached
By Liquidity, over 92% of Exchanges on 9.1.0 - the desired hard fork threshold for exchanges has been reached
TVL by top 20 DApp projects are over 83% ready, with steady progress and testing on PreProd from August 24.
Core infrastructure encompasses all technologies included within the Cardano Node, as well as key tools.

The Chang #1 hardfork will introduce governance to Cardano, specific tooling is being developed to support the governance model.
Whilst having governance tools prepared for mainnet hardfork is ideal, these tools should not block mainnet hardfork.
