CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic.
Deliver a battle-tested, auditable codebase in 2-4 weeks, not months.
- Security-First Process: Development follows OpenZeppelin standards, includes automated analysis (
Slither,MythX), and is structured for third-party audits. - Production Architecture: Implement upgrade patterns (
Proxy,Diamond), efficient data structures, and gas optimization to minimize user costs. - Full Lifecycle Support: From initial spec and development through to mainnet deployment, verification, and monitoring.

PROVEN PROCESS
Our Delivery Methodology
Our systematic approach ensures your cross-chain DePIN bridge is delivered on time, secure by design, and ready for mainnet. We focus on predictable outcomes, not just technical execution.
01
Architecture & Specification
We begin with a collaborative design session to define your bridge's core logic, supported chains (e.g., Ethereum, Solana, Polygon), and token standards (ERC-20, SPL). This phase delivers a complete technical specification and architecture diagram, ensuring alignment before a single line of code is written.
3-5 days
Design Sprint
100%
Spec Alignment
02
Secure Contract Development
Our engineers write production-grade Solidity and Rust contracts using established patterns (e.g., OpenZeppelin, Wormhole SDK). Every module—from the lock/unlock mechanism to the relayer network—is built with gas efficiency and upgradeability in mind from day one.

Rigorous Testing & Simulation
We deploy your bridge to a dedicated testnet environment for exhaustive testing. This includes unit tests, integration tests with live RPC nodes, and stress simulations of high-volume cross-chain transfers to validate performance and fee mechanics under load.

Security Audit & Final Review
Before mainnet deployment, the complete bridge system undergoes an internal security review against common vulnerabilities (reentrancy, oracle manipulation). We prepare a comprehensive audit report and remediation plan, ensuring your contracts are production-ready.

Frequently Asked Questions
Get clear answers on timelines, costs, security, and support for your custom DePIN bridge contract development.
A standard cross-chain DePIN bridge from specification to mainnet deployment takes 4-6 weeks. This includes 1 week for design and architecture, 2-3 weeks for core contract development and internal testing, and 1-2 weeks for security audits and final deployment. Complex multi-asset or multi-chain deployments can extend to 8-10 weeks. We provide a detailed project plan with milestones at kickoff.
