Tezos Unveils Etherlink 7.0 Upgrade Proposal with Michelson Interface and NAC

Tezos has unveiled its latest upgrade proposal for its Ethereum Virtual Machine (EVM)-compatible rollup, Etherlink Mainnet. The update, dubbed Etherlink 7.0, introduces two critical features: the Michelson interface and Native Atomic Composability (NAC). This marks a significant milestone in bridging the gap between Tezos' native functionality and Ethereum's ecosystem.

The Michelson interface will enable Tezos accounts and smart contracts to operate natively within Etherlink. Previously, Etherlink primarily supported the EVM interface, limiting interaction with Tezos-native features. With this new interface, developers gain direct access to Tezos accounts (tz1, tz2, tz3) and Michelson contracts, integrating them into Etherlink's unified ledger.

Native Atomic Composability (NAC) is another standout feature of Etherlink 7.0. It allows seamless, trustless interaction between the EVM and Michelson interfaces. For example, Tezos accounts can now hold Etherlink-native assets, while EVM accounts can call Michelson smart contracts.

The upgrade also introduces enhancements to Etherlink's EVM interface, including support for triggering script execution on tez deposits and proper gas refunds for precompile contract reverts. These changes bring Etherlink closer to standard EVM semantics, improving developer experience and compatibility.
