Enterprise-grade smart contract development with formal verification and comprehensive security audits.
We architect and deploy secure, gas-optimized smart contracts for tokens, DeFi protocols, and NFTs. Our process includes formal verification and multiple audit rounds before mainnet deployment.
ERC-20, ERC-721, and ERC-1155 implementations.Reduce your time-to-market from months to weeks with our battle-tested development framework.
We provide end-to-end ownership including deployment scripts, upgradeability patterns using TransparentProxy, and post-launch monitoring. All code follows OpenZeppelin standards and is written in Solidity 0.8+.
Our multi-chain bridge integration delivers production-ready infrastructure with enterprise SLAs, built on battle-tested protocols and audited security patterns.
Integrate a single, unified SDK supporting Wormhole, Axelar, LayerZero, and Polygon Supernets. Eliminate vendor lock-in and future-proof your application with modular architecture.
Deploy custom bridge relayers and asset vaults with up to 40% lower gas costs. Built on Solidity 0.8+ with OpenZeppelin security patterns and formal verification.
Monitor cross-chain message flow, bridge health, and liquidity pools with sub-second latency. Get instant alerts for failed transactions or security anomalies.
Enterprise-grade MPC/TSS wallet infrastructure for managing bridge operator keys. Includes hardware security module (HSM) integration and multi-signature governance.
Our multi-chain bridge integration delivers measurable results for your wallet's growth, security, and user experience.
Unlock users from Ethereum, Solana, Polygon, and other major L1/L2 networks with a single, seamless integration. Expand your total addressable market without managing separate wallet infrastructures.
Implement battle-tested bridge contracts with formal verification. We ensure secure cross-chain message passing and asset locking/unlocking, protecting user funds with audited, non-custodial protocols.
Deploy a production-ready, white-labeled bridge integration in weeks, not months. Leverage our pre-built connectors and SDKs to bypass the complexity of cross-chain consensus and relayers.
Dynamically route transactions through the most cost-effective networks and bridges. Our integration includes gas estimation and sponsorship logic to minimize user friction and operational costs.
Drive deeper engagement with features like cross-chain NFT displays, unified portfolio views, and in-wallet swap functionality. Increase session duration and transaction frequency.
Guarantee wallet availability with redundant bridge infrastructure and 99.9% uptime SLAs. Our managed service includes automatic failover, health checks, and performance monitoring.

Our battle-tested, four-phase methodology ensures your multi-chain wallet bridge is secure, scalable, and ready for production in weeks, not months.
We begin with a deep audit of your existing wallet architecture and threat model. Our team designs a secure bridge integration blueprint using industry standards like ERC-4337 for account abstraction and implements multi-signature or MPC custody models.
We develop and deploy custom, gas-optimized bridge contracts on your target chains (EVM, Solana, Cosmos). Contracts are built with Solidity 0.8+ or Rust, leveraging OpenZeppelin libraries and following best practices for reentrancy and overflow protection.
We implement a high-availability relayer network for cross-chain message passing and integrate with decentralized oracles (Chainlink, Pyth) for secure price feeds and state verification. Includes failover mechanisms and monitoring.
Rigorous testing across testnets (Sepolia, Amoy, Solana Devnet) using frameworks like Hardhat and Foundry. We perform final security checks, assist with mainnet deployment, and provide comprehensive documentation for your team.
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom Solidity/Rust smart contracts that form the immutable foundation of your protocol. Our process ensures zero critical vulnerabilities through formal verification and multi-firm audits.
OpenZeppelin standards, automated testing, and a 99.9% uptime SLA for mainnet deployments.ERC-20/ERC-721 tokenomics to upgradeable proxy patterns and on-chain governance modules.Deliver a battle-tested, gas-optimized contract suite in as little as 4 weeks, reducing your technical risk and accelerating your go-to-market.
Get clear, technical answers on timelines, security, and process for integrating a custom multi-chain wallet bridge.
A standard multi-chain bridge integration takes 4-8 weeks from kickoff to mainnet deployment. This includes 2 weeks for architecture & smart contract development, 2 weeks for integration & testing on testnets, and 2 weeks for security audits and final deployment. Complex protocols with custom logic or support for >5 chains may extend this timeline.
