Build vs. Buy: The Infrastructure Trade-Off
A detailed comparison of the time, cost, and risk of building a sanctions screening system in-house versus using Chainscore's managed API.
| Factor | Build In-House | Chainscore API |
|---|---|---|
Time to Initial Deployment | 6-12 months | 2-4 weeks |
Initial Development Cost | $150K - $400K+ | From $15K/month |
Coverage (Blockchains & Assets) | Requires per-chain integration | 40+ chains, 100M+ assets |
Real-time List Updates | Manual, lagging process | Automated, <5 minute latency |
Compliance & Audit Trail | Your responsibility to build | Fully automated & exportable |
Ongoing Engineering & Ops | 2-3 FTE engineers | Fully managed service |
Security & Risk Exposure | High (custom, unaudited logic) | Low (audited, battle-tested) |
Total Cost of Ownership (Year 1) | $500K - $1M+ | $180K - $500K |
Scalability to New Chains | Months of development per chain | Enabled by default, no extra work |

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our contracts are built with OpenZeppelin standards, undergo rigorous multi-stage audits, and are optimized for gas efficiency and security from day one.
From tokenization to complex DeFi protocols, we deliver contracts that are secure, upgradeable, and ready for mainnet.
- Token Systems:
ERC-20,ERC-721,ERC-1155, andSPLtokens with custom minting, vesting, and governance logic. - DeFi & DApps: Automated Market Makers (AMMs), staking pools, lending protocols, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, asset tokenization platforms, and compliant KYC/AML integration modules.
- Full Lifecycle: Development, testing (
Hardhat/Foundry), auditing, deployment, and post-launch monitoring.

Frequently Asked Questions for Technical Leaders
Technical questions we receive from CTOs and engineering leads evaluating our sanctions screening infrastructure.
For a standard integration with your existing wallet or transaction flow, typical deployment is 2-3 weeks. This includes initial scoping, API key provisioning, integration testing, and a pilot phase with a subset of your user traffic. Complex multi-chain deployments or custom rule engines may extend this to 4-6 weeks.
