Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts on EVM and Solana chains. Our development process is built for security and speed, delivering a minimum viable product (MVP) in 2-4 weeks.
ERC-20 tokens to complex DeFi protocols and NFT marketplaces.OpenZeppelin standards and undergoes internal audits before deployment.We don't just write code; we build the foundational logic for your on-chain business.
Our team handles the entire lifecycle:
Hardhat/Foundry and Solana-Web3.js with comprehensive test suites.Etherscan/Solscan.Proxy patterns.We architect and deploy secure, scalable mobile identity solutions with on-chain attestations, enabling your FinTech or Web3 application to onboard users with confidence and compliance.
Seamlessly embed our lightweight, battle-tested SDK into your iOS/Android apps. We handle the complex cryptography for key generation and secure enclave storage, so you can focus on user experience.
Generate and verify tamper-proof identity claims directly on-chain using standards like EIP-712 and EAS (Ethereum Attestation Service). We ensure your attestations are portable, verifiable, and interoperable across ecosystems.
Implement selective disclosure of user credentials using ZK-SNARKs. Users prove they meet your criteria (e.g., age > 18, country) without revealing the underlying sensitive data, ensuring maximum privacy.
Deploy attestations that are natively verifiable across Ethereum, Polygon, Arbitrum, and other EVM chains. We build the relayers and message-passing layers for true chain-agnostic identity.
Integrate automated checks for sanctions screening (OFAC), AML, and jurisdictional rules directly into the attestation flow. Our rules engine updates in real-time to keep you compliant.
Rely on our globally distributed, fault-tolerant network of attestation signers and verifiers. We provide 99.9% uptime SLAs with automated failover to ensure your identity layer never goes down.
Integrating Mobile Identity Shield with Attestations delivers measurable improvements in security, user experience, and operational efficiency. Here’s what you can expect.
Leverage on-chain attestations to verify unique human users, reducing fraudulent sign-ups and bot-driven spam by over 95% and protecting your airdrop campaigns and incentive programs.
Replace complex seed phrases and manual wallet connections with seamless, secure mobile-native authentication. Reduce user drop-off during sign-up by up to 70%.
Enable biometric or passkey-protected signing for every transaction directly within your mobile app. Remove dependency on external wallets, increasing conversion rates for in-app purchases and swaps.
Create a verifiable, user-owned identity graph with attestations for activity, KYC status, or community standing. This portable reputation unlocks cross-application trust and personalized experiences.
Automate identity verification and audit trails using immutable attestations. Drastically cut manual review workloads and provide regulators with transparent, tamper-proof proof of compliance.
Our tiered service model allows you to start with core attestation features and scale to a fully managed, enterprise-grade identity layer. Compare features, support, and pricing to find your fit.

We deliver Mobile Identity Shield with a structured, security-first approach designed for rapid integration and enterprise-grade reliability.
We begin with a deep-dive analysis of your user flows and threat vectors. Our team designs a tailored attestation architecture, selecting the optimal on-chain verifiers (Ethereum, Solana, Polygon) and off-chain attestation services (EAS, Verax) for your use case.
We provide a battle-tested, lightweight SDK for iOS and Android. Integration includes secure key management, biometric authentication hooks, and seamless interaction with decentralized identity protocols (DIDs, VCs).
Our team deploys and configures custom smart contract verifiers on your chosen L1/L2. Contracts are built with Solidity 0.8+ using OpenZeppelin libraries and include gas optimization for batch attestations.
Every component undergoes rigorous review. Our smart contracts are audited by third-party firms, and the mobile SDK is subjected to manual penetration testing focusing on reverse engineering and key extraction.
We manage a full staging deployment on testnets, conduct load testing, and provide a detailed runbook for your team. Our engineers are on-call during your production launch to ensure a smooth rollout.
Gain real-time visibility with our dedicated dashboard. Monitor attestation volume, fraud attempts, system health, and user adoption metrics to inform product decisions and security posture.
A detailed breakdown of the costs, risks, and time commitments associated with developing a secure mobile attestation system in-house versus leveraging Chainscore's production-ready platform.

Get clear answers on how our attestation-based mobile identity solution integrates, scales, and secures your Web3 applications.
Standard integration takes 2-3 weeks from kickoff to production. This includes initial scoping, SDK integration, attestation logic configuration, and a security review. For complex custom attestation rules or multi-chain deployments, timelines may extend to 4-5 weeks.
