Multi-VM L2 Interoperability API

A unified API layer enabling secure communication and shared state between smart contracts across EVM, SVM, and MoveVM-based Layer 2 networks. We build custom solutions to connect your fragmented ecosystem.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contract development for DeFi, NFTs, and enterprise applications.

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.

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 CertiK or Quantstamp.
  • Full Lifecycle: We handle development, testing (Hardhat/Foundry), deployment, and post-launch monitoring.

PROVEN PROCESS

Our Delivery Methodology: From Audit to API

A structured, security-first approach to deliver production-ready, interoperable infrastructure in weeks, not months.

01

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.
