We architect and deploy production-grade smart contracts that are secure by design. Our process includes formal verification, comprehensive unit testing, and third-party audits to eliminate vulnerabilities before mainnet deployment.
Wallet Interoperability Bridge
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
Deliver a market-ready product with a 99.9% uptime SLA and gas costs optimized for your users' wallets.
- Custom Logic:
ERC-20,ERC-721,ERC-1155, DeFi primitives, DAO governance, and bespoke business rules. - Security First: Built with
Solidity 0.8+andOpenZeppelinlibraries, following industry-standard security patterns. - Full Lifecycle: From initial design and development to deployment, monitoring, and upgrade management via transparent proxies.
Core Technical Capabilities We Deliver
We architect and deploy secure, scalable wallet interoperability bridges that connect your users across any chain. Our solutions are built for production from day one.
Multi-Chain Wallet SDK
A unified SDK supporting EVM, Solana, and Cosmos chains, enabling single-click wallet connections and asset management across ecosystems. Reduces integration time by 80%.
Secure Message Signing & Verification
Enterprise-grade cryptographic signing infrastructure with MPC/TSS options. Implements EIP-712, EIP-191, and Solana's Ed25519 standards for secure cross-chain authentication.
Gas Abstraction & Sponsorship Engine
Allow users to pay fees in any token or enable gasless transactions. Our relayers handle fee estimation and sponsorship, removing a major UX barrier for new users.
Real-Time State Synchronization
Maintain consistent user session, balance, and NFT data across all connected chains. Built on event-driven architecture with sub-second finality for a seamless multi-chain experience.
Custom Connector Development
Need to support a proprietary wallet or a new L1/L2? We build custom wallet adapters and signer integrations, ensuring your bridge works with any signing method.
Production Monitoring & Analytics
Gain visibility with dashboards tracking bridge health, user adoption per chain, transaction success rates, and gas spending. Proactive alerts for any anomaly.
Business Outcomes for Your Wallet Product
Our Wallet Interoperability Bridge delivers concrete technical and commercial advantages, enabling you to scale user acquisition and revenue.
Multi-Chain User Onboarding
Enable users from any major chain (Ethereum, Solana, Polygon, etc.) to access your dApp in one click, eliminating the fragmentation that blocks 70% of potential users.
Reduced Development Overhead
Integrate a single, audited bridge API instead of building and maintaining custom connectors for each blockchain, cutting your infrastructure roadmap by months.
Enhanced Security & Trust
Deploy with confidence using our bridge, which undergoes regular audits by firms like CertiK and implements formal verification for core settlement logic.
Increased Transaction Revenue
Capture cross-chain swap fees and gas monetization opportunities by becoming the primary gateway for users moving assets between ecosystems.
Faster Time-to-Market
Go live with a production-ready bridge in under 4 weeks, not quarters. Our modular SDKs and white-label solutions accelerate your launch.
Superior User Experience
Offer sub-2-second finality for cross-chain actions and abstract away gas complexities, leading to higher retention and satisfaction scores.

Our Delivery Methodology
We deliver secure, scalable wallet bridges through a structured, transparent workflow designed for enterprise-grade reliability and rapid deployment.
Architecture & Protocol Audit
We begin with a deep technical assessment of your existing wallet infrastructure and target chains. Our team analyzes security models, gas efficiency, and protocol compatibility to design an optimal bridge architecture.
Smart Contract Development
Our engineers build modular, upgradeable bridge contracts using Solidity 0.8+ and OpenZeppelin libraries. We implement multi-signature controls, rate limiting, and comprehensive event logging for full transparency.
Relayer & Oracle Integration
We deploy and configure high-availability relayers with automatic failover. Our oracle network provides secure, decentralized price feeds and state verification for cross-chain messaging.
Staging & Mainnet Deployment
We deploy to a private testnet for final validation, followed by a phased mainnet rollout. Our team manages the deployment process end-to-end, including contract verification and frontend integration.
Monitoring & Incident Response
Post-launch, we provide 24/7 monitoring dashboards, alerting for anomalous activity, and a documented incident response playbook. We offer ongoing support for upgrades and maintenance.
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy mission-critical smart contracts for tokens, DeFi protocols, and NFTs. Our process delivers audit-ready code in 2-4 weeks, built on Solidity 0.8+ with OpenZeppelin security patterns and comprehensive testing.
We focus on security and gas efficiency from day one, preventing costly exploits and optimizing for mainnet deployment.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155with minting, vesting, and governance modules. - DeFi Logic: Automated Market Makers (AMMs), liquidity pools, staking, and yield strategies.
- Security First: Formal verification, unit/integration testing, and pre-audit reviews to meet
ConsenSys Diligencestandards.
Frequently Asked Questions
Get clear answers about our cross-chain wallet bridge development process, security, and support.
A standard, production-ready wallet interoperability bridge from Chainscore Labs typically deploys in 4-6 weeks. This includes design, smart contract development, frontend integration, security audit, and mainnet deployment. Complex multi-chain deployments or novel bridging mechanisms can extend to 8-10 weeks. We provide a detailed project plan with weekly milestones upon engagement.
