Avalanche Subnet Cross-Chain Liquidity Bridge

We build custom bridge and messaging infrastructure to connect liquidity between Avalanche's C-Chain and your application-specific Subnet, enabling seamless, secure asset transfers for DeFi protocols.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contract systems built to your exact specifications.

We architect and deploy production-grade smart contracts that are secure by design. Every line of code is written in Solidity 0.8+ following OpenZeppelin standards and undergoes rigorous internal review before a formal audit.

  • Custom Tokenomics: Design and implement ERC-20, ERC-721, or ERC-1155 tokens with complex vesting, minting, and governance logic.
  • DeFi Primitives: Build automated market makers (AMMs), lending pools, staking vaults, and yield aggregators.
  • Enterprise Logic: Develop custom business logic for supply chain, gaming, or identity verification on-chain.

We deliver a fully tested, documented, and audit-ready codebase in 2-4 weeks for an MVP, with a guaranteed 99.9% uptime SLA post-deployment on your network of choice.

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect, develop, and deploy custom Solidity/Rust smart contracts that form the backbone of your Web3 product. Our focus is on security-first development, gas optimization, and long-term maintainability.

Deploy with confidence using battle-tested code that has secured over $50M+ in on-chain value.

  • Full Lifecycle Development: From initial design and Foundry/Hardhat testing to mainnet deployment and verification.
  • Security as Standard: All contracts undergo internal audits against common vulnerabilities (reentrancy, overflow) and integrate OpenZeppelin libraries.
  • Protocol-Specific Logic: Custom implementations for ERC-20, ERC-721, staking systems, multi-signature wallets, and bespoke DeFi mechanics.

Frequently Asked Questions

Get clear answers on timelines, costs, and technical details for your custom cross-chain liquidity bridge.

A standard, production-ready cross-chain bridge for an Avalanche Subnet typically takes 6-10 weeks from design to mainnet deployment. This includes smart contract development, security audits, and integration testing. Pricing is project-based, with standard deployments starting at $80,000. Complex requirements like custom governance, multi-asset support, or advanced MEV protection increase scope and cost. We provide a fixed-price quote after a technical discovery session.
