Developers building on Neo N3 and Neo X can now integrate wallet connections through a single setup, using a new set of open-source AppKit adapters released by COZ. The adapters plug into Reown AppKit, formerly WalletConnect AppKit, which supports over 600 wallets along with features like social logins and multi-chain authentication.
The release extends COZ’s long-running work on WalletConnect infrastructure in the Neo ecosystem, which began in 2021 when the team first brought WalletConnect support to Neo N3. The AppKit adapters shift the focus to the dApp side, providing developer tooling that removes the need for custom wallet connection implementations.
Three adapters, two approaches
The adapters are published as separate npm packages under the `@cityofzion` scope, each tailored to the technical requirements of its target chain.
As Neo N3 is not EVM-compatible, it requires a custom adapter that overrides Reown AppKit’s default configuration to support its methods and namespaces. The Neo N3 adapter provides a Neo3Provider for chain interactions such as contract invocations, and ships with pre-configured MainNet and TestNet network definitions.
Neo X, being fully EVM-compatible, takes a different path. Its package provides pre-configured network definitions and utilities rather than a custom adapter, working with the standard Wagmi adapter from Reown AppKit. It includes configurations for Neo X’s anti-MEV transaction system, with dedicated MainNet and TestNet network options for MEV-resistant routing. Developers using the anti-MEV feature need to use the sendTransaction function from COZ’s package rather than standard Wagmi hooks.
Connect Lab demo
COZ has also published Connect Lab, a demo application for testing wallet connections across supported chains. The tool is hosted from the project’s monorepo and serves as both a reference implementation and a practical testing environment for developers integrating the adapters.
