Core Integration Capabilities We Deliver
We architect and implement secure, scalable wallet integrations that connect your users to the blockchain. Our proven methodologies ensure rapid deployment and enterprise-grade reliability.
Multi-Chain Wallet SDK Integration
Seamlessly embed wallet functionality for Ethereum, Solana, Polygon, and other leading L1/L2 networks. We handle the protocol-specific complexities, providing a unified interface for your application.
Secure Transaction & Signing Infrastructure
Build robust transaction flows with MPC, smart contract wallets, or direct EOA signing. Includes gas optimization, nonce management, and comprehensive error handling for production reliability.
Real-Time Blockchain Data Syncing
Implement real-time balance, token, and NFT indexing. We connect to high-performance RPC nodes and indexing services to ensure your UI reflects the latest on-chain state without delays.
Custom dApp Connector & Provider Development
Develop branded wallet connection modals, network switching, and provider injection compatible with MetaMask, WalletConnect, and Coinbase Wallet standards, ensuring a flawless user onboarding experience.
Why Professional Wallet Integration Matters
Secure, scalable wallet infrastructure is not a feature—it's the foundation of user trust and application success. Our enterprise-grade integration delivers measurable outcomes.
Security-First Architecture
We implement MPC-based key management, hardware security module (HSM) integration, and comprehensive audit trails. Protect user assets with institutional-grade security from day one.
Multi-Chain & Multi-Wallet Support
Seamlessly integrate MetaMask, WalletConnect, Coinbase Wallet, and custom embedded wallets. Support EVM, Solana, and Cosmos chains with a unified API.
Reduced Time-to-Market
Leverage our pre-built, battle-tested SDKs and integration patterns. Go from concept to production-ready wallet features in weeks, not months.
Enterprise-Grade Reliability
Guaranteed 99.9% uptime SLA with multi-region failover. Our infrastructure handles spikes in transaction volume without degrading user experience.
Compliance & Audit Readiness
Built-in transaction monitoring, KYC/AML hooks, and comprehensive logging. Stay ahead of regulatory requirements with programmable compliance rules.
Ongoing Protocol Support
We continuously update integrations for new EIPs, wallet standards (ERC-4337, 1271), and chain upgrades. Your integration stays current without constant rework.
Build vs. Buy: Wallet Integration
A detailed comparison of the total cost, risk, and time investment required for in-house development versus partnering with Chainscore for custom wallet integration.
| Key Factor | Build In-House | Partner with Chainscore |
|---|---|---|
Time to Market | 4-9 months | 4-8 weeks |
Initial Development Cost | $150K - $300K+ | $50K - $150K |
Security & Audit Overhead | High (unaudited, custom code) | Low (pre-audited patterns, formal verification) |
Team Requirements | 3-5 Senior Blockchain Devs | Your Product Team + Our Experts |
Ongoing Maintenance & Updates | Your team's responsibility (2+ FTEs) | Optional SLA with 24/7 monitoring |
Multi-Chain Support Complexity | High (per-chain integration) | Built-in (EVM, Solana, Cosmos SDK) |
Feature Depth (DeFi, NFTs, Gas) | Basic to Moderate | Advanced (Sponsorship, Batch, Account Abstraction) |
Total Cost of Ownership (Year 1) | $300K - $600K+ | $80K - $200K |
Our Delivery Process
We follow a structured, milestone-driven approach to deliver secure, production-ready wallet integrations on time and within scope.
Discovery & Architecture
We analyze your tech stack, user flows, and security requirements to design a tailored integration blueprint. This includes selecting optimal wallet protocols (WalletConnect v3, MPC, AA) and defining key metrics for success.
Secure Development & Testing
Our engineers build the integration using audited libraries (like ethers.js v6, viem) and implement comprehensive security checks. Every module undergoes unit, integration, and penetration testing before staging.
Staging & Security Audit
We deploy to a staging environment identical to production for final validation. The code undergoes an internal security review focused on private key management, transaction signing, and RPC endpoint security.
Deployment & Monitoring
We manage the production deployment and integrate real-time monitoring for wallet connection success rates, transaction failures, and RPC health. You receive full documentation and handover support.
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
We architect and deploy custom smart contracts that form the foundation of your Web3 application. Our development process ensures security-first code, gas optimization, and full audit readiness from day one.
Deliver a secure, functional MVP in as little as 2-3 weeks.
Our development stack includes:
- Solidity 0.8+ with OpenZeppelin libraries and established security patterns.
- Hardhat/Foundry for comprehensive testing and local development.
- EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base) and Solana with
@solana/web3.js. - Integration of oracles (Chainlink), decentralized storage (IPFS/Arweave), and cross-chain bridges.
What you get:
- Complete codebase with documentation and deployment scripts.
- Security review against common vulnerabilities (reentrancy, overflow).
- Gas usage analysis to minimize user transaction costs.
- Post-deployment support for upgrades and maintenance.
Wallet Integration FAQs
Answers to the most common questions from CTOs and product leads evaluating custom wallet integration partners.
Our process is structured for predictability and speed. We follow a 4-phase methodology: Discovery & Scoping (1 week), Architecture & Design (1-2 weeks), Development & Integration (2-4 weeks), and Security Review & Deployment (1 week). A typical project for a multi-chain wallet with core DeFi integrations launches in 4-8 weeks. We provide weekly demos and a dedicated project manager for transparency.
