Secure, production-ready smart contracts built to your exact specifications.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Every contract is built with OpenZeppelin standards, undergoes rigorous security audits, and is optimized for gas efficiency and upgradability.
Deliver a secure, audited MVP in as little as 2-4 weeks.
ERC-20, ERC-721, ERC-1155 with advanced minting, vesting, and governance.We architect and deploy custom identity frameworks that are secure by design, developer-friendly, and production-ready from day one. Our solutions are built to scale with your AppChain's growth.
We design and implement bespoke identity primitives (SBTs, Verifiable Credentials, on-chain attestations) tailored to your AppChain's specific governance, reputation, or access control needs.
Production-grade identity logic written in Solidity 0.8+, leveraging OpenZeppelin libraries. Every contract undergoes rigorous internal review and is prepared for third-party audits by firms like CertiK or Quantstamp.
We specialize in minimizing gas costs for identity lifecycle events (minting, updating, revoking) through efficient data structures and state management, ensuring user adoption isn't hindered by fees.
Enable identity portability across chains. We implement cross-chain messaging (LayerZero, Axelar) and standard-compliant interfaces (EIP-4973, EIP-5560) so your user identities are not siloed.
Build with regulatory considerations in mind. We implement privacy-preserving techniques like zero-knowledge proofs (ZKPs) for selective disclosure and design for GDPR/Data Portability compliance.
A purpose-built identity layer is a competitive moat. It enables faster user onboarding, unlocks new revenue models, and ensures compliance without sacrificing user experience.
We deliver a production-ready identity framework in under 4 weeks, not months. Our modular components for authentication, authorization, and credential management integrate directly with your AppChain's consensus and state.
Design seamless, chain-specific flows. Implement gasless onboarding, social logins, and session keys that abstract wallet complexity, reducing user drop-off by up to 70% compared to generic solutions.
Embed regulatory requirements like KYC/AML directly into the protocol logic. Our frameworks support verifiable credentials (W3C VC), selective disclosure, and audit trails, ensuring enterprise-grade compliance from day one.
Unlock new revenue streams with programmable identity. Implement soulbound tokens for reputation, subscription NFTs for gated access, and cross-dApp loyalty programs that increase user LTV.
Maintain full control over your user identity graph and security model. Avoid third-party dependencies with a framework audited for common vulnerabilities (e.g., signature replay, Sybil attacks) and built on OpenZeppelin libraries.
Designed for a multi-chain future. Our frameworks include bridges for portable identity, enabling users to bring their reputation and assets across ecosystems while maintaining your AppChain as the home base.

A structured, four-phase methodology designed to deliver a secure, scalable, and fully operational identity framework for your AppChain. We provide clear milestones, regular demos, and guaranteed outcomes at every step.
We conduct a deep technical workshop to define your AppChain's specific identity requirements, including token-gating logic, role-based access control (RBAC), and compliance needs. The output is a detailed technical specification document and a fixed-scope project plan.
Client Value: Eliminates scope creep, aligns all stakeholders, and provides a predictable timeline and budget from day one.
Our engineers design and implement the core smart contract suite (e.g., Soulbound Tokens, Verifiable Credential Registry, Permission Manager) using Solidity 0.8+ and OpenZeppelin libraries. This includes gas optimization and integration patterns for your specific consensus mechanism.
Client Value: A secure, auditable, and gas-efficient identity layer built to your exact specifications, ready for independent security review.
The completed smart contracts undergo a rigorous internal security review followed by an optional third-party audit with partners like Spearbit or Code4rena. We then deploy and thoroughly test the entire framework on a designated testnet, simulating real-world user flows.
Client Value: Mitigates catastrophic risk with professional security validation and ensures system stability before mainnet launch, protecting your users and reputation.
We manage the secure deployment to your AppChain's mainnet, configure initial admin roles, and execute a monitored launch plan. Comprehensive documentation and developer training are provided, followed by a support handover to your internal team.
Client Value: A fully operational, production-ready identity framework with zero deployment headaches and the knowledge to maintain and extend it independently.

Common questions about our custom identity framework development for AppChains and rollups.
We deliver a production-ready, audited identity framework in 4-8 weeks. The timeline depends on complexity: a standard ERC-4337-compatible smart account system with social recovery takes ~4 weeks. Adding custom primitives like zk-proof reputation or multi-chain attestations extends the timeline. We provide a detailed project plan within the first week of engagement.
