With the Merge, complete attention turns to Cardano and its up-and-coming Vasil hard fork.

Vasil was initially scheduled for release on Jun. 29, but a heightened approach triggered by the Terra implosion and the discovery of bugs led to delays.

At the start of September, Input Output (IO) confirmed a rollout date of Sept. 22. Two weeks later, the developers updated their “Ecosystem readiness” article confirming the upgrade remains on track for release.

Vasil to usher in Cardano global adoption

Vasil falls under the Basho era of Cardano, which is about optimization and improving the chain’s scaling and interoperability. Basho is considered a stepping stone to realizing the chain’s ambitions of global adoption by enabling high transaction volume.

Specifically, Vasil will achieve optimization through a series of improvements, including diffusion pipelining, for more efficient block propagation and implementing several Cardano Improvement Proposals (CIPs) that center around data storage and access efficiencies.

“The upgrade will bring significant improvements using Cardanoโ€™s hard fork combinator (HFC) approach and enhance the networkโ€™s performance by increasing throughput, script efficiency, and reducing latency in block transmission.”

What is the latest?

Three indicators must reach “critical mass” to trigger the Vasil mainnet upgrade.

  • 75% of the mainnet blocks must be created by Vasil version 1.35.3 node candidate.
  • 25 exchanges must have upgraded to the latest software version.
  • The top 10 dApps (by TVL) must confirm the use of version 1.35.3.

As of Sept. 15, 98% of the block production was done using the updated software, meaning stake pool operators (SPOs) have done their part.

IO has split exchanges into “top” and “other” based on the ADA volume they handle. In total, across both categories, 21 exchanges are ready.

However, several top exchanges are still working on implementing the upgrade, including Coinbase,, and HitBTC. With yet to start the process.

Of the other exchanges still working on the implementation, notable examples include Kraken,, Kucoin, and Huobi.

Regarding the dApps, IO has listed 12 projects, half of which have completed their testing and are ready to go. However, at writing, Minswap, SundaeSwap, MuseliSwap, ADAX Pro, VyFinance, and Meld have yet to finalize testing.

In summary, the Vasil upgrade is waiting on a handful of exchanges and dApps to accept the updated software version.
