Mezo March Update

March has been a big month for Mezo. Under the hood, the network completed not one but two major node upgrades — and on the surface, we made it easier for even more of you to connect. Let’s break it all down.

New Wallets Supported

Two of the most-requested wallets in the community are now officially supported on Mezo: Bitget Wallet and Rabby Wallet. Bitget Wallet is one of the fastest-growing multi-chain wallets in the world, with tens of millions of users across crypto, and they’ve been wanting to use Mezo. Same goes for Rabby Wallet, the fan-favorite from DeBank that’s known for its clean UI and security-first approach. Both wallets had been at the top of community wish lists, and we listened.

If you’ve been holding off on getting into Mezo because your preferred wallet wasn’t supported, now’s a great time to dive in. Head to mezo.org and connect with Bitget or Rabby.

What’s Happening in the App

The Mezo app keeps growing. Here’s a quick snapshot of what’s live and active right now:

• Vaults — Earn yield on your Bitcoin assets without the complexity. The vault lineup includes the MUSD Savings Vault (powered by Mezo), BTC Vault, Stablecoin Vault, and cbBTC Vault.
• Liquidity Pools — With over $6.3M in total value locked, the Mezo liquidity pools are picking up steam. Active pairs include BTC/MUSD, mcbBTC/BTC, mUSDC/MUSD, mUSDC/mcbBTC, and BTC/mxSolvBTC. Provide liquidity, earn fees, and stake LP tokens for additional rewards. It’s your Bitcoin, working overtime.
• Rewards (NEW!) — Mezo now has a dedicated Rewards section in the app. This is where ecosystem participation pays off. Stay tuned for more details as this feature gets fully rolled out.

Node Upgrades: v7.0.0 and v8.0.0 — What Just Happened

March brought two mandatory network upgrades to Mezo. First, on March 23rd, the network upgraded to v7.0.0 — boosting EVM compatibility up to the Cancun fork. Then, on March 25th, v8.0.0 landed, laying the groundwork for the upcoming Triparty feature. Neither of these is just a version bump. They represent meaningful steps forward for the platform and for builders.

Mezo’s EVM is now compatible up to the Cancun fork. That means more of the Ethereum tooling and smart contract ecosystem is now compatible with Mezo, bringing broader developer reach and a more robust platform for builders.

Both upgrades were mandatory for all Mezo Mainnet nodes. v7.0.0 required an upgrade before block 7,691,500 (March 23rd), and v8.0.0 required an upgrade before block 7,739,500 (March 25th). If you run a validator and haven’t updated yet, do it now — upgrading a node before its designated block causes a failure.

Developer Corner: v7.0.0 and v8.0.0

v7.0.0 upgrades Mezo’s EVM to Cancun-level compatibility. Here’s what that means for you in plain terms:

• Modern Solidity tooling now works.
• Hardhat, Foundry, and contracts using post-Merge opcodes are now fully supported.
• Less friction when porting from Ethereum.
• PREVRANDAO replaces DIFFICULTY. If any of your contracts use the DIFFICULTY opcode for randomness or entropy, update them to PREVRANDAO, or they’ll return unexpected values.
• No blob transactions. Mezo explicitly rejects EIP-4844 blob txs. They’re not part of Mezo’s architecture. If your tooling sends blobs, it will fail. Disable them in your config.
• v8.0.0 lays the groundwork for Triparty. Key changes include: new state change observability primitives are introduced (so the chain can track and react to asset state changes), and the AssetsBridge precompile gets new methods to support the Triparty BTC minting flow. If you’re building on Mezo, expect more details on Triparty as it approaches launch.
• Node operators: v7.0.0 and v8.0.0 are both mandatory upgrades. Docker images: mezo/mezod:v7.0.0 and mezo/mezod:v8.0.0.
