Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on Solidity 0.8+ and OpenZeppelin standards, ensuring security and interoperability from day one.
Deliver a battle-tested, gas-optimized contract suite in 2-4 weeks.
Our full-cycle development includes:
ERC-20, ERC-721, ERC-1155, DAOs, staking, and DeFi protocols.We specialize in complex, multi-contract systems for:
Our modular SDKs and APIs provide the foundational security layer for your mobile Web3 app, enabling seamless user onboarding while maintaining full custody and compliance.
Replace clunky seed phrases with secure, device-native biometric authentication (Face ID/Touch ID). Maintain authenticated sessions with encrypted local storage, balancing security with UX.
Implement fine-grained access controls for dApp interactions. Define session scopes for token approvals, transaction limits, and contract interactions to minimize risk and build user trust.
Automatically generate immutable logs for all authentication events and sensitive sessions. Essential for regulatory compliance (Travel Rule, KYC) and security monitoring without compromising privacy.
Our globally distributed session nodes guarantee 99.9% uptime for auth services. Automated failover and geo-redundancy ensure your users can always access their wallets and dApps.
Our Mobile Web3 Auth & Session Management service delivers measurable infrastructure improvements, directly impacting your application's security, user growth, and operational efficiency.
Implement MPC-TSS-based key management for frictionless mobile sign-ups. Users own their keys while you eliminate the risks and liabilities of seed phrase storage, reducing support tickets by up to 70%.
Enable persistent, secure sessions with social logins (Google, Apple) or passkeys. Users can switch devices without re-authenticating wallets, increasing daily active users (DAU) and session duration.
Abstract gas fees for end-users with secure paymaster integration. Sponsor user operations to drive adoption of network interactions, removing a major barrier to entry for non-crypto-native users.
Leverage audited smart accounts (ERC-4337) and session key modules with granular permissions. Built with OpenZeppelin standards and undergoes regular third-party security reviews.
Deploy on our managed, auto-scaling RPC nodes with sub-second latency. Gain insights into wallet creation, transaction trends, and user behavior through integrated dashboards.
Integrate our SDKs and APIs in under 2 weeks. We provide full documentation, dedicated technical support, and reference architectures for popular DePIN stacks like Helium and Render.
Compare the total cost of ownership, risk, and time-to-market between developing a custom solution in-house versus leveraging Chainscore's battle-tested platform.
| Factor | Build In-House | Buy with Chainscore |
|---|---|---|
Time to Production | 4-9 months | 2-4 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Annual Maintenance Cost | $80K - $200K (2-3 FTE) | Optional SLA from $30K/year |
Security & Audit Overhead | High (unaudited, custom code) | Low (pre-audited, standardized modules) |
Supported Chains & Wallets | Limited to team's expertise | EVM, Solana, 20+ wallets, MPC |
Session Key Management | Custom implementation risk | Pre-built with key rotation & revocation |
Infrastructure Scaling | Your team's responsibility | Managed, auto-scaling backend |
Compliance (KYC/AML) | Custom integration required | Pre-integrated partner ecosystem |
Team Focus | Diverted from core product | Remains on core product innovation |
Total Cost (Year 1) | $230K - $600K+ | $55K - $105K |
We deliver production-ready mobile Web3 authentication in weeks, not months, using a battle-tested framework that prioritizes security and user experience.
We design the optimal auth flow for your use case, selecting from SIWE (Sign-In with Ethereum), MPC-TSS, or Passkey-based solutions. We ensure compatibility with your mobile stack (React Native, Flutter, native iOS/Android).
We build a custom, lightweight SDK for your app. Features include secure key management, session refresh logic, and seamless integration with wallets (MetaMask, WalletConnect, Particle).
We deploy a scalable, non-custodial session manager. This includes JWT/refresh token issuance, rate limiting, and audit logging—all without ever touching user private keys.
We deploy to a staging environment for integration testing. We provide comprehensive documentation and runbooks for your team to validate flows before production.
We manage the production rollout and provide 24/7 monitoring dashboards for auth success rates, error tracking, and performance metrics via tools like Datadog or Sentry.
A structured delivery plan for integrating secure, non-custodial mobile authentication into your application.

Answers to the most common questions CTOs and product leads ask when evaluating authentication infrastructure for their mobile dApps.
We focus on custom, white-label SDKs for mobile-first experiences, not a one-size-fits-all widget. While providers like Web3Auth offer general SDKs, we build solutions integrated directly into your native app's UX, with custom session logic, gas sponsorship flows, and multi-chain key management tailored to your specific user journey and security model.
