CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts that power your core business logic, from tokenomics to governance. Our contracts are built on Solidity 0.8+ with OpenZeppelin standards, undergo rigorous security audits, and are optimized for gas efficiency and upgradeability.
Deliver a secure, audited MVP in as little as 2 weeks.
Our development lifecycle ensures reliability and speed:
- Architecture & Design: Protocol specification and security-first design patterns.
- Development & Testing: Comprehensive unit/integration tests with 95%+ coverage.
- Audit & Deployment: Third-party audit coordination and mainnet deployment support.
- Maintenance: Proactive monitoring and upgrade management via
Proxypatterns.
We specialize in contracts for:
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155with minting, vesting, and tax logic. - DeFi Protocols: DEXs, lending/borrowing pools, staking, and yield aggregators.
- NFT Projects: Generative collections, marketplaces, and dynamic metadata engines.
- Enterprise Logic: Multi-signature wallets, asset tokenization, and compliant KYC/AML modules.

Frequently Asked Questions
Get clear answers on how Chainscore Labs delivers secure, compliant, and scalable institutional-grade Bitcoin custody solutions.
We build on a multi-signature, multi-party computation (MPC) architecture using industry-leading providers like Fireblocks or Copper. This eliminates single points of failure. The bridge itself is a custom, audited smart contract on the destination chain (e.g., Ethereum, Polygon) that manages wrapped asset minting/burning based on verifiable on-chain proofs from the Bitcoin network. We implement threshold signatures for key management, ensuring no single entity holds a complete private key.
