Mezo v6 is live

Mezo v6.0.0 went live at block 6773500 and is the most comprehensive network upgrade to date.

TLDR:

  • Apps can now do more in a single transaction, unlocking richer DeFi flows, better automation, and more user abstraction.
  • Price-sensitive features like liquidations, swaps, and collateral checks can react faster to BTC and MUSD market moves because onchain prices are now updating closer to real-time.
  • Native BTC deposits are significantly faster.

Read on for feature details.

Cross-chain MEZO

A significant focus of this release cycle was hardening how MEZO moves between EVM chains when it is deployed. As a result, moving MEZO across supported environments becomes more predictable and robust.

Here are the specific PR updates made:

BTC deposit throughput

Native BTC deposits previously could, in some cases, require manual protocol-level processing, which led to delays ranging from hours to days. With this release, Mezo doubles deposit throughput and adds automated processing that eliminates that bottleneck. Deposits now clear automatically, without manual intervention.

Oracle price update frequency

Accurate pricing is critical for any protocol built on Mezo.

Mezo introduced Pyth scheduler manifests to manage oracle jobs more cleanly at the protocol level. On top of that, we increased the update frequency for BTC/USD and MUSD/USD price feeds. On-chain prices now track real-time markets more closely.

This was driven by market maker feedback and improves the accuracy of anything price-dependent

Safer and more flexible complex transactions

Mezo v6 introduces a governable limit on the number of Mezo native precompile calls a single transaction can make.

Previously, complex multi-step DeFi logic was constrained by a hard cap on how many precompile calls a transaction could include. The limit is now governable and can be adjusted via the Maintenance precompile as the ecosystem matures, without requiring a new network upgrade. Governance can tune this limit over time as the ecosystem evolves, balancing safety with the needs of advanced builders.

Node and consensus upgrades

Under the hood, Mezo upgraded CometBFT to v0.38.21, pulling in upstream consensus and stability improvements that strengthen the validator layer Mezo runs on. Testnet validators and Mainnet RPC were aligned on the v5.0.0 line ahead of this rollout to ensure a clean, coordinated transition into v6.0.0.

What’s next

v6.0.0 expands what is possible on Mezo. Builders have more flexibility, more precise pricing, stronger cross-chain mechanics, and a more resilient base layer. Users get a network that is better equipped to handle complexity and growth. In the coming weeks, expect applications and integrations to begin leaning into the capabilities unlocked by this release.
