Secure, production-ready smart contracts built by Web3 experts.
We architect and deploy custom smart contracts that form the backbone of your dApp. Our development process ensures security-first design, gas optimization, and comprehensive testing before mainnet launch.
Solidity 0.8+ and OpenZeppelin libraries.Hardhat and Foundry.Move from concept to a live, secure contract in as little as 2-4 weeks.
Our engineers specialize in:
We handle the complex, ongoing technical operations of your multi-chain identity wallet so your team can focus on product innovation and user growth.
Real-time monitoring of wallet interactions across all supported chains (EVM, Solana, Cosmos, etc.). We detect and alert on anomalies, failed transactions, and network congestion before they impact your users.
Seamless, zero-downtime updates for critical dependencies like wallet SDKs (Web3.js, ethers.js, WalletConnect), RPC providers, and chain-specific libraries. We manage version compatibility and regression testing.
Proactive application of security patches for wallet core, key management libraries, and signature schemes. Includes monitoring for CVEs related to used frameworks and immediate remediation.
Management of high-availability, load-balanced RPC endpoints and archival nodes. We ensure low-latency connections, handle provider failover, and optimize for cost and performance across all chains.
Weekly and monthly reports on wallet performance metrics: transaction success rates, gas fee trends, user onboarding funnel, and cross-chain bridge efficiency. Data-driven insights for your product team.
Dedicated on-call engineering team for critical production incidents. We provide rapid diagnosis, mitigation, and post-mortem analysis for issues related to connectivity, signing, or state synchronization.
Our managed service transforms your multi-chain identity wallet from a technical burden into a strategic asset. We handle the complexity so your team can focus on building features that drive user acquisition and revenue.
Proactive monitoring and automated failover across all supported chains (Ethereum, Solana, Polygon, etc.) ensure your users always have access. We manage node health, RPC endpoint optimization, and disaster recovery.
Stay ahead of threats and regulatory changes. We implement automated security patches, monitor for vulnerabilities in wallet dependencies, and maintain compliance with evolving standards (e.g., ERC-4337, Solana Token Extensions).
Eliminate the overhead of hiring and managing a specialized infrastructure team. Our fixed-fee model covers all maintenance, monitoring, and upgrade costs, turning unpredictable OpEx into a predictable line item.
Integrate new chains (e.g., Base, Arbitrum) and wallet standards (e.g., ERC-7579) in days, not months. Our team handles the integration complexity, allowing your developers to ship user-facing features faster.
Direct access to senior blockchain engineers, not just a support ticket queue. We provide architectural guidance, performance tuning, and dedicated support to ensure your wallet scales with your user base.
Compare the long-term operational burden and cost of maintaining a multi-chain identity wallet yourself versus our fully managed service.

Total Year 1 Cost | $180K - $350K+ | $60K - $120K |
Key-Man Risk | High (specialized knowledge) | Eliminated |
Time-to-Market for New Features | Slowed by maintenance | Accelerated |
We don't wait for problems to happen. Our systematic, data-driven approach ensures your multi-chain identity wallet infrastructure remains secure, performant, and ready to scale.
24/7 monitoring of wallet node health, RPC endpoints, and cross-chain bridge status across all supported networks (Ethereum, Polygon, Arbitrum, etc.). We track uptime, latency, and error rates to catch anomalies before they impact users.
Automated deployment of critical security patches and dependency updates for wallet libraries (e.g., ethers.js, web3.js) and smart contract dependencies. We manage the update lifecycle from testing to staged rollout.
Continuous analysis of transaction patterns and gas fees across chains. We provide actionable recommendations and automated configurations to reduce user transaction costs by optimizing batching and network selection.
Regular audits of smart contract interactions, token allowances, and third-party SDKs for compliance with latest standards (EIP-712, EIP-4337) and to identify potential vulnerabilities or deprecated dependencies.
Proactive load testing and capacity planning based on user growth metrics. We simulate peak traffic scenarios to ensure wallet connectivity and transaction signing performance scales seamlessly.
Reliable, scalable node infrastructure for production-grade Web3 applications.
We manage the core infrastructure so you can focus on building. Chainscore provides dedicated, high-availability nodes with 99.9% uptime SLAs for networks like Ethereum, Solana, Polygon, and Arbitrum. Our global deployment ensures sub-second latency and eliminates the operational overhead of self-hosting.
Deploy in hours, not weeks, with enterprise-grade reliability built-in.
dApps.Get clear, specific answers about our maintenance service for multi-chain identity wallets, including timelines, security, and support.
Our standard package includes 24/7 wallet infrastructure monitoring, automated key rotation and backup verification, regular security patch deployment for wallet SDKs and dependencies, and proactive performance optimization. We also provide a 99.9% uptime SLA for core wallet connectivity and a 4-hour response time for critical issues. This is based on our experience managing over 50 production wallets securing $500M+ in assets.
