IC-js and Oisy Wallet Signer move to new @icp-sdk/core framework

The Internet Computer developer ecosystem continues to evolve, with ic-js and Oisy Wallet Signer now powered by @icp-sdk/core, a new modular package designed to simplify and modernise development on the network.

The update replaces the older AgentJS stack — which included libraries such as @dfinity/agent and @dfinity/principal — with a single, multi-entrypoint structure under @icp-sdk/core. While the change is largely structural, developers are being encouraged to update dependencies to ensure compatibility with future versions.

The development team marked the upgrade as a major release to ensure visibility across the community. Updated packages include a wide range of DFINITY components such as ckBTC, ckETH, CMC, IC Management, Ledger ICP, Ledger ICRC, NNS, SNS, Utils, Zod Schemas, and Oisy Wallet Signer.

According to the announcement, both Oisy and the NNS dapp were migrated to the new stack before the broader release, helping to confirm its reliability and stability. This move, the team says, reflects their commitment to maintaining high standards for developer experience while keeping the ecosystem battle-tested in production.

Developers are also being encouraged to migrate imports to the new @icp-sdk/core sub-path exports, with a migration guide available for reference. The transition marks another stride towards a cleaner, modular toolkit for Internet Computer projects.

The team behind the release hinted that more is on the way. Work is already underway to publish the ic-js canisters library using the same multi-entrypoint structure. Although still awaiting formal documentation, the library is already available on npm for developers keen to explore it early.

The shift toward @icp-sdk/core reflects the maturing nature of Internet Computer development, as projects like Juno, Oisy, and NNS continue to adopt the latest SDK patterns. With these updates, the community moves closer to a more unified, scalable framework for building dapps and integrations across the ICP ecosystem.
