Wallet integration

This guide covers the technical requirements for integrating Concordium blockchain support into a crypto wallet. It walks you through core protocol features and key architectural decisions. Whether you’re evaluating Concordium for integration or ready to begin implementation, this guide provides the foundation for making informed decisions.

Integration overview

Concordium is a Layer-1 proof-of-stake blockchain with a built-in identity layer at protocol level balancing user privacy with regulatory compliance. The platform supports multiple transaction types, offers native staking and delegation functionality, and uses an efficient gRPC-based node communication protocol.

Integrating Concordium involves implementing support for several protocol-specific features:

• Identity layer management: handling verified on-chain identities

• Zero-knowledge proofs (ZKPs): managing cryptographic proofs for privacy-preserving identity verification

• Transaction types: supporting CCD transfers, smart contracts, staking, and protocol-level tokens

• Staking functionality: enabling users to delegate CCD and earn rewards

In addition to implementing these features, you’ll need to establish network connectivity through Concordium’s gRPC-based communication protocol. You may consider using a wallet proxy for simplified data handling.
