Secure, production-ready smart contracts built by Web3 experts for your protocol or application.
We architect and deploy custom smart contracts that form the secure, immutable backbone of your Web3 product. Our development process is built on audited security patterns and battle-tested standards like ERC-20, ERC-721, and ERC-1155.
Deploy a secure, gas-optimized MVP in as little as 2 weeks, not months.
Solidity 0.8+ contracts to frontend integration with ethers.js/wagmi.OpenZeppelin standards and undergoes internal audits before deployment to mainnet.We build the foundational payment infrastructure that scales with your business. Our multi-currency sub-account rails are engineered for security, speed, and seamless integration.
Our multi-currency sub-account rails deliver measurable improvements to your platform's core financial operations, from user acquisition to treasury management.
Enable users to deposit and trade in 50+ currencies instantly, reducing the signup-to-first-trade funnel by up to 70%. No more waiting for fiat conversions or external wallet funding.
Automate the consolidation of multi-currency revenue into your preferred settlement asset. Reduce manual reconciliation overhead and optimize for better FX rates with batch settlements.
Isolate user funds in dedicated, non-custodial sub-accounts. Mitigate co-mingling risk, simplify compliance audits, and protect your platform's core treasury from operational exposure.
Launch in new regions without building local payment infrastructure. Our rails handle currency acceptance, local compliance checks, and cross-border settlement, cutting time-to-market from months to weeks.
A technical and financial comparison for CTOs deciding between in-house development, generic third-party APIs, and Chainscore's purpose-built multi-currency sub-account rails.
| Key Factor | Build In-House | Generic Wallet API | Chainscore Rails |
|---|---|---|---|
Time to Market | 6-12+ months | 2-4 weeks | 4-8 weeks |
Upfront Development Cost | $200K - $500K+ | $0 - $50K | $50K - $150K |
Multi-Chain Native Support | Custom per chain | Limited / Wrapped | Native (EVM, Solana, etc.) |
Sub-Account Isolation & Compliance | You build it | Not available | Built-in, audited |
Smart Contract Security Risk | High (unaudited) | Medium (shared risk) | Low (independently audited) |
Ongoing Maintenance & DevOps | Full team required | Vendor manages API | Optional SLA with 99.9% uptime |
Custom Business Logic Integration | Fully customizable | Rigid, limited hooks | Fully customizable |
Settlement Finality & Speed | Your implementation | Varies, often slow | Sub-2 seconds target |
Total Cost of Ownership (Year 1) | $300K - $700K+ | $20K - $100K + hidden ops | $80K - $200K (predictable) |
Strategic Control & IP Ownership | Full ownership | Vendor lock-in | Full ownership, your keys |
We deliver production-ready multi-currency payment rails through a structured, client-focused process. Each phase is designed to de-risk your project, ensure technical excellence, and accelerate your time-to-market.
We conduct a technical deep-dive to define your token standards (ERC-20, ERC-777), settlement logic, and sub-account isolation model. Deliverables include a detailed technical specification and a high-level architecture diagram.
Our engineers build your core payment rail contracts using Solidity 0.8+ with OpenZeppelin libraries. We implement gas-optimized logic for multi-token transfers, sub-account management, and role-based access control.
All smart contracts undergo rigorous internal testing and a formal audit by a third-party security firm. We provide a comprehensive audit report and implement all critical recommendations before deployment.
We integrate the payment rail with your existing front-end and back-end systems. This includes comprehensive testing on testnets (Sepolia, Mumbai) for functionality, load, and security.
We manage the secure, phased deployment to mainnet (Ethereum, Polygon, etc.), including contract verification on Etherscan, initial configuration, and provisioning of admin dashboards for monitoring.
Post-launch, we provide 30 days of included support and monitoring via dedicated dashboards. We offer ongoing maintenance packages for upgrades, new feature development, and 24/7 incident response.
Answers to common technical, process, and pricing questions for CTOs and founders evaluating our payment infrastructure service.
A standard multi-currency sub-account deployment takes 2-4 weeks from kickoff to production. This includes smart contract development, integration with your frontend/backend, security audit, and testnet deployment. Complex requirements like custom compliance logic or multi-chain support can extend this to 6-8 weeks. We provide a detailed project plan within 48 hours of initial scoping.
