We architect and deploy production-grade smart contracts on Ethereum, Solana, and other leading L1/L2 networks. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and formal verification patterns to mitigate risk.
Multi-VM L2 Interoperability API
Smart Contract Development
Secure, audited smart contract development for DeFi, NFTs, and enterprise applications.
From token standards to complex DeFi logic, we deliver contracts that are secure, gas-optimized, and ready for mainnet.
- Custom Logic: Build
ERC-20,ERC-721,ERC-1155, and bespoke contracts for DeFi protocols, DAOs, and marketplaces. - Security & Audits: Every contract undergoes internal review and optional third-party audits from firms like
CertiKorQuantstamp. - Full Lifecycle: We handle development, testing (
Hardhat/Foundry), deployment, and post-launch monitoring.
Core Capabilities of Your Custom API
Your dedicated Multi-VM L2 Interoperability API is engineered to solve the core technical challenges of cross-chain development, delivering production-ready infrastructure that accelerates your time-to-market.
Unified Multi-VM Abstraction
A single API endpoint to interact with EVM, SVM, and MoveVM-based Layer 2s. Eliminate the complexity of managing separate RPC providers, SDKs, and transaction formats for each virtual machine.
Client Value: Reduce integration time by 70% and cut ongoing maintenance overhead.
Atomic Cross-VM Messaging
Secure, non-custodial message passing between different VM environments (e.g., Solana <-> Arbitrum). Built on audited, canonical bridges with configurable finality guarantees to match your risk profile.
Client Value: Enable complex multi-chain DeFi strategies and NFT interoperability with guaranteed execution.
Gas & Fee Optimization Engine
Intelligent fee estimation and transaction bundling across heterogeneous L2 networks. Our system dynamically selects the optimal chain and route based on current congestion, cost, and speed requirements.
Client Value: Lower end-user transaction costs by up to 40% and improve UX with predictable pricing.
Enterprise-Grade Security & Monitoring
Every API is deployed with dedicated, isolated infrastructure. Includes real-time anomaly detection for cross-chain flows, comprehensive audit logging, and optional integration with your existing SIEM (Splunk, Datadog).
Client Value: Meet strict compliance requirements and monitor cross-chain activity with bank-grade security tooling.
Custom Logic & Smart Contract Hooks
Inject your business logic directly into the interoperability layer. Define custom validation rules, automated responses to cross-chain events, and complex settlement conditions without modifying your core dApp.
Client Value: Create unique, defensible product features and automate complex multi-chain workflows.
Dedicated Infrastructure & Support
Your API is not a shared service. It runs on infrastructure provisioned exclusively for you, with a dedicated engineering liaison and 24/7 on-call support for P1 incidents. Includes performance dashboards and weekly health reports.
Client Value: Eliminate "noisy neighbor" risks and get expert support to ensure your cross-chain operations run smoothly.
Business Outcomes: From Complexity to Revenue
Our Multi-VM Interoperability API transforms technical complexity into direct business value, accelerating your time-to-market and unlocking new revenue streams.
Accelerated Time-to-Market
Launch cross-chain applications in weeks, not months. Our pre-audited, production-ready API abstracts the complexity of EVM, SVM, and MoveVM interactions, allowing your team to focus on core product logic.
Unified Liquidity Access
Tap into aggregated liquidity across Ethereum, Solana, Aptos, and Sui with a single API call. Eliminate the need to build and maintain separate integrations for each ecosystem.
Reduced Operational Risk
Deploy with confidence using our battle-tested, formally verified message-passing protocols. Built-in security patterns and continuous monitoring protect against cross-chain bridge vulnerabilities.
Scalable Revenue Architecture
Enable new fee models and monetization strategies by facilitating seamless asset and data movement. Support complex DeFi primitives, NFT marketplaces, and gaming economies across multiple VMs.
Future-Proof Development
Easily integrate emerging Virtual Machines (e.g., FuelVM, CairoVM) without rewriting your core application. Our modular architecture ensures your stack is never locked into a single ecosystem.
Enterprise-Grade Support
Get dedicated technical support, comprehensive documentation, and architectural guidance from engineers who have deployed cross-chain systems handling billions in volume.

Our Delivery Methodology: From Audit to API
A structured, security-first approach to deliver production-ready, interoperable infrastructure in weeks, not months.
1. Architecture & Security Audit
We begin with a deep technical assessment of your existing smart contracts and L2 strategy. Our team identifies interoperability bottlenecks, gas inefficiencies, and security vulnerabilities before a single line of new code is written.
Deliverable: A comprehensive audit report with prioritized recommendations for secure cross-VM communication.
2. Smart Contract Development
Our engineers build custom, gas-optimized smart contracts for your specific use case—be it cross-chain asset bridging, state synchronization, or message passing. We implement battle-tested patterns from OpenZeppelin and Chainlink CCIP.
Deliverable: Production-ready, audited Solidity/Vyper contracts deployed to your testnet.
3. Multi-VM Node Orchestration
We provision and configure dedicated, high-availability nodes across your target L2s (Arbitrum, Optimism, zkSync, etc.). This includes setting up secure RPC endpoints, block explorers, and health monitoring for each virtual machine environment.
Deliverable: A fully managed node infrastructure with 99.9% SLA and real-time monitoring dashboards.
4. Interoperability API Layer
We develop a unified REST/GraphQL API that abstracts the complexity of interacting with multiple L2s. This layer handles transaction routing, fee estimation, state proof verification, and failover logic, providing a single integration point for your dApp.
Deliverable: A documented, versioned API with SDKs for JS/Python/Go and comprehensive test suites.
5. Load Testing & Optimization
Before launch, we simulate real-world traffic to stress-test the entire system—from contract calls to API endpoints. We identify and resolve bottlenecks, ensuring your infrastructure can handle peak loads and scale predictably.
Deliverable: A performance report with benchmarks for TPS, finality times, and cost-per-transaction under load.
6. Production Deployment & SLA
We manage the seamless deployment to mainnet, including final security checks and configuration. You receive 24/7 monitoring, alerting, and dedicated technical support, backed by a service level agreement covering uptime, latency, and incident response.
Deliverable: A live, production-grade Multi-VM Interoperability API with ongoing support and maintenance.

Frequently Asked Questions
Get clear answers about our API that enables seamless communication between EVM, SVM, and Move-based Layer 2 networks.
Standard integration for a single application takes 2-3 weeks. This includes initial setup, smart contract deployment on your target chains, and end-to-end testing. For more complex ecosystems connecting 3+ different VMs, the timeline extends to 4-6 weeks. We provide a detailed project plan during the discovery call.
