Identity Wallet SDK Development

Custom SDKs and developer tools for integrating decentralized identity (DID) and verifiable credential (VC) wallet functionalities into your existing applications.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your protocol.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your application. Our development process is built on Solidity 0.8+ with OpenZeppelin libraries and follows formal verification principles to eliminate critical vulnerabilities.

From tokenomics to complex DeFi logic, we translate your business rules into gas-optimized, auditable code.

  • End-to-End Development: Token standards (ERC-20, ERC-721, ERC-1155), DeFi primitives (AMMs, lending/borrowing), and custom governance systems.
  • Security-First Process: Multi-stage audits, including internal review and integration with leading third-party firms before mainnet deployment.
  • Guaranteed Outcomes: 99.9% uptime SLA for deployed contracts and 2-week MVP delivery for standard token implementations.

BUILT FOR SCALE

Why Choose Custom SDK Development

Off-the-shelf SDKs create integration bottlenecks and security vulnerabilities. Our custom Identity Wallet SDKs are engineered for your specific use case, ensuring seamless user onboarding, robust security, and a foundation for rapid growth.

01

Tailored Protocol Integration

Native support for your required standards (ERC-4337, SIWE, Verifiable Credentials) and blockchain networks. We build the SDK to match your stack, not the other way around.

Sign-In Standard
02

Enterprise-Grade Security

Built with secure enclaves, MPC key management, and zero-knowledge proofs. Every SDK undergoes formal verification and third-party audits (e.g., Trail of Bits) before delivery.

Our Development Process

A structured, milestone-driven approach to deliver a production-ready Identity Wallet SDK in 8-12 weeks, from initial architecture to final deployment.

01

Discovery & Architecture

We conduct a deep technical assessment to define your wallet's core requirements: key management strategy (MPC vs. custodial), target protocols (EVM, Solana, Cosmos), and compliance needs (KYC/AML). You receive a detailed technical specification and project roadmap.

Identity Wallet SDK Development: FAQs

Get clear answers to the most common questions CTOs and product leads ask when evaluating a custom identity wallet SDK partner.

For a standard multi-chain identity wallet with core features (key management, transaction signing, DID methods), we deliver a production-ready SDK in 4-6 weeks. Complex integrations (e.g., zk-proofs, MPC custody, custom attestation schemas) extend this to 8-12 weeks. We work in 2-week sprints with demos, ensuring alignment and allowing for iterative feedback.
