GenLayer moves Bradbury testnet to Arbitrum Nitro stack

The GenLayer Foundation said the AI smart-contract project had completed its migration from Matter Labs’ ZK Stack to the Arbitrum Nitro stack. Conduit operates the chain infrastructure.

The Foundation said the Bradbury testnet was already running on the new stack. The future Clarke testnet and mainnet are also planned to use it; the report did not say they were live.

The migration affects bridging, Ethereum integration and how on-chain gas costs are handled. According to the Foundation, the core protocol and the way smart contracts run remain unchanged. GenLayer is also continuing to explore a private, permissioned institutional chain deployment based on Prividium with Matter Labs.
