ICPanda launches x402 V2 to simplify payments on the Internet Computer

ICPanda has rolled out x402 V2, an upgrade designed to make payment facilitators easier to integrate into the x402 ecosystem on the Internet Computer. The update follows the recent upgrade of the Anda x402 Facilitator to V2, with application use cases now in development and set to expand across the Anda Cloud ecosystem.

The Anda x402 Facilitator is a fully on-chain payment smart contract that supports multiple ICRC-2 compatible tokens. It handles payment verification, settlement, and logging, offering both Candid and HTTP APIs for developers. The system manages payment states, fees, and transaction logs entirely on-chain, providing transparency and reliability.

ICPanda says the V2 upgrade ensures facilitators can plug into the wider x402 network more easily, offering standardised endpoints for verifying and settling payments. The HTTP API supports both JSON and CBOR formats, while the Candid API enables administrative functions such as adding or removing supported payment kinds, updating assets, and collecting fees. This makes it easier for developers to implement a range of payment scenarios without needing custom infrastructure.

The canister is fully deployed on the Internet Computer and governed by the ICPanda DAO, maintaining decentralised oversight. Developers can deploy it locally using Dfinity’s dfx tool, add supported assets like the PANDA token, and use the Typescript SDK to interact with the canister programmatically. Example applications and full deployment instructions are available on ICPanda’s GitHub repository.

By supporting multiple token types and integrating directly with the x402 payment protocol, x402 V2 offers flexibility for a range of projects within the Anda Cloud ecosystem. Facilitators can process payments, verify authorisations, and settle transactions in real-time, while ensuring operations remain fully on-chain. This makes it possible for applications to handle complex financial flows without relying on off-chain intermediaries.

ICPanda’s upgrade reflects the broader growth of the Internet Computer as a platform for general-purpose applications. By providing standardised, fully on-chain payment tools, the project aims to reduce friction for developers and encourage wider adoption of ICP-based infrastructure. Facilitators and developers alike benefit from improved transparency, decentralisation, and integration capabilities.

The public endpoints for the x402 V2 Facilitator are live, enabling developers to explore supported payment types, verify authorisations, and settle payments directly. The project also provides comprehensive API documentation, making it straightforward to integrate with both new and existing applications.

ICPanda’s move positions the Internet Computer as a more robust environment for on-chain payments, emphasising flexibility, security, and ease of use for developers building applications that rely on digital assets and tokenised payments.
