On-Chain Sanctions Oracle Maintenance

A fully managed service to develop, deploy, and maintain a decentralized oracle network that provides verifiable, up-to-date sanctions lists directly to your smart contracts.
Chainscore © 2026
overview
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. Our development process ensures security-first design, gas optimization, and regulatory compliance from day one.

Deliver a secure, audited MVP in as little as 2-3 weeks.

  • Protocol Development: Custom ERC-20, ERC-721, ERC-1155, and bespoke token standards.
  • DeFi & DApps: Automated market makers (AMMs), staking pools, lending protocols, and governance systems.
  • Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and supply chain verifiers.
  • Security Guarantee: All contracts undergo rigorous internal audits and are built with OpenZeppelin libraries.

Our engineers specialize in Solidity, Vyper, and Rust (for Solana), implementing patterns for upgradability and modularity. We provide full documentation and deployment scripts for seamless integration.

Frequently Asked Questions on Sanctions Oracle Maintenance

Get clear, specific answers about our on-chain sanctions oracle maintenance service, from deployment timelines to security guarantees and ongoing support.

Standard sanctions oracle deployment takes 2-3 weeks from kickoff to mainnet launch. This includes integration with your chosen data provider (e.g., Chainalysis, TRM Labs), smart contract development and audit, and configuration for your target chains. Complex multi-chain deployments or custom rule engines may extend this to 4-5 weeks.
