We architect and deploy custom smart contracts that form the backbone of your Web3 product. Our development process is built on security-first principles, utilizing battle-tested libraries like OpenZeppelin and rigorous internal audits before deployment to mainnet.
Decentralized Identity (DID) API Suite
Smart Contract Development
Secure, production-ready smart contracts built by experts for DeFi, NFTs, and enterprise applications.
From concept to mainnet in as little as 2-4 weeks for an MVP, accelerating your time-to-market while ensuring robustness.
- Token Standards:
ERC-20,ERC-721,ERC-1155, and custom implementations. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, lending/borrowing logic.
- Enterprise Logic: Multi-signature wallets, DAO governance, and asset tokenization frameworks.
- Full Audit Support: We prepare comprehensive documentation for third-party audits from firms like CertiK or Quantstamp.
Complete DID & Verifiable Credential Lifecycle
Our API suite handles the entire lifecycle—from creation and issuance to verification and revocation—so you can focus on building user-centric applications without managing complex cryptographic infrastructure.
DID Creation & Management
Generate and manage W3C-compliant DIDs (did:key, did:web) with secure key storage. We handle key rotation, recovery, and delegation, ensuring user sovereignty and developer simplicity.
Credential Issuance
Issue tamper-proof Verifiable Credentials (VCs) using JSON-LD or JWT formats. Our templates support selective disclosure and zero-knowledge proofs for privacy-preserving attestations.
Credential Verification
Perform instant, cryptographically secure verification of VCs. Our service validates proofs, checks revocation status, and ensures schema compliance before returning a clear verification result.
Revocation & Status Management
Maintain secure, privacy-preserving revocation registries. Choose from status lists or accumulator-based methods to revoke credentials without leaking user identity or credential details.
Secure Storage & Presentation
Provide users with a secure, encrypted wallet SDK for storing credentials and generating Verifiable Presentations. Supports CHAPI and SIOPv2 for seamless, user-controlled data sharing.
Audit Logging & Compliance
Maintain immutable, GDPR-compliant audit trails for all issuance and verification events. Generate reports for regulators and demonstrate adherence to data protection principles.
Why Leading FinTechs Choose Our DID Suite
Our Decentralized Identity API Suite is engineered for financial services, delivering the security, compliance, and performance required to build trust at scale.
Compliance-Ready Architecture
Built-in support for W3C DID standards, Verifiable Credentials, and GDPR/KYC/AML compliance workflows. We provide the audit trails and data residency controls your legal team requires.
Sub-Second Identity Verification
Leverage our globally distributed node infrastructure for < 500ms DID resolution and credential verification. Eliminate user drop-off with banking-grade latency.
Zero-Knowledge Proof Integration
Enable privacy-preserving KYC with zk-SNARKs and zk-STARKs. Users prove eligibility (age, jurisdiction) without exposing raw data, reducing your liability surface.
Multi-Chain & Interoperable
Deploy identity anchors across Ethereum, Polygon, Solana, and Cosmos. Our cross-chain messaging protocol ensures portable identities and credentials.
Developer-First SDKs
Ship in weeks, not months. Our TypeScript, Python, and Go SDKs include pre-built modules for onboarding flows, credential issuance, and wallet integration.
Managed Security & Key Custody
HSM-backed key management with multi-party computation (MPC) for decentralized custody. We handle key rotation, backup, and disaster recovery so you don't have to.

Healthcare & Pharma
Manage verifiable credentials for patient data access, clinician licensing, and clinical trial participation with HIPAA-aligned privacy controls and selective disclosure.
Government & Public Sector
Deploy citizen digital IDs, verifiable permits, and secure voting credentials. Built on open standards (W3C DIDs/VCs) for interoperability and public auditability.
Social & Creator Platforms
Build trust and combat spam with verified creator profiles and community badges. Enable users to own their social graph and reputation across platforms.
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We architect, develop, and deploy custom Solidity/Rust smart contracts that form the immutable logic layer of your application. Every contract is built with security-first principles, leveraging battle-tested libraries like OpenZeppelin and following industry standards (ERC-20, ERC-721, ERC-1155).
- Full Lifecycle Development: From initial specification and architecture to deployment, verification, and post-launch monitoring.
- Comprehensive Audits: Internal security review and integration with top external audit firms for final validation.
- Gas Optimization: Code is meticulously optimized for lower transaction costs and efficient on-chain execution.
- Upgradeability Patterns: Implementation of secure proxy patterns (
TransparentProxy,UUPS) for future-proof, mutable logic where required.
We deliver audited, production-grade contracts in 2-4 weeks, giving you a secure and scalable foundation to build upon.
Decentralized Identity API FAQs
Get clear answers on implementation, security, and support for our enterprise-grade DID infrastructure.
A standard integration of our DID API Suite takes 2-4 weeks from kickoff to production. This includes environment setup, credential schema configuration, integration with your existing auth stack, and a security review. Complex customizations (e.g., novel zero-knowproof circuits) may extend this timeline, which we scope and quote upfront.
