We architect, develop, and audit custom Solidity and Rust smart contracts for DeFi, NFTs, and enterprise applications. Our contracts are built on OpenZeppelin standards and include formal verification for critical logic.
AppChain Customization for Institutional Payments
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Security-First Development: Every contract undergoes internal review and automated analysis before deployment.
- Gas Optimization: We achieve up to 40% gas savings through efficient data structures and opcode-level tuning.
- Full Lifecycle Support: From initial design and testing to mainnet deployment and upgrade management via Transparent Proxies.
Deliver a secure, auditable, and maintainable codebase that forms the trusted foundation of your on-chain application.
Core Customization Modules for Payment AppChains
Pre-built, battle-tested modules designed to accelerate your institutional payment AppChain development. Each module is production-ready, security-audited, and optimized for high-volume settlement.
Multi-Asset Settlement Engine
A high-throughput engine supporting native tokens, wrapped assets (ERC-20), and stablecoins with atomic swaps. Enables cross-currency payments with sub-second finality and automated FX rate oracles.
Regulatory Compliance Hub
Built-in modules for KYC/AML checks, transaction monitoring, and sanctions screening. Supports programmable rulesets for different jurisdictions and generates auditable compliance reports.
Institutional Wallet & Custody
Secure, non-custodial smart contract wallets with multi-signature governance, role-based access controls, and hardware security module (HSM) integration for private key management.
Cross-Chain Bridge Connector
Secure, audited bridge modules to connect your payment AppChain to major L1s (Ethereum, Solana) and L2s (Arbitrum, Polygon). Uses optimistic or zero-knowledge verification for asset transfers.
Real-Time Analytics & Reporting
On-chain analytics dashboard for monitoring payment flows, liquidity pools, and transaction fees. Provides APIs for custom reporting and integration with enterprise BI tools.
Fee Management & Treasury
Flexible fee structuring engine supporting fixed fees, percentage-based fees, and dynamic pricing. Includes automated treasury management for revenue distribution and protocol-owned liquidity.
Business Outcomes for Payment Providers
Our custom AppChain infrastructure delivers measurable improvements in cost, speed, and compliance for institutional payment platforms.
Sub-Second Settlement
Finalize high-value cross-border payments in under 1 second, eliminating multi-day delays and counterparty risk inherent in traditional correspondent banking.
Cost Reduction > 90%
Drastically lower transaction fees by bypassing intermediary banks. Our gas-optimized chains reduce per-transaction costs to fractions of a cent for high-volume payment corridors.
Enterprise-Grade Security & SLAs
Deploy on a dedicated, permissioned chain with 99.9% uptime SLA. Infrastructure includes multi-signature governance, regular security audits, and disaster recovery protocols.
Seamless Fiat Integration
Connect to existing banking rails and payment processors via secure, audited on/off-ramp bridges. Supports stablecoin issuance and direct CBDC interoperability pilots.
Scalable Liquidity Management
Implement automated liquidity pools and treasury management smart contracts to optimize capital efficiency across payment networks and currency pairs.
Custom AppChain vs. Public Layer-1 for Institutional Payments
A technical and operational comparison for CTOs and architects evaluating dedicated blockchain infrastructure against public networks for high-value payment systems.
| Key Factor | Public Layer-1 (e.g., Ethereum, Solana) | Chainscore Custom AppChain |
|---|---|---|
Transaction Cost Predictability | Volatile, market-driven gas fees | Fixed, deterministic fee structure |
Settlement Finality | Probabilistic (minutes to hours) | Instant, deterministic (< 2 seconds) |
Throughput & Scalability | Shared, limited by network congestion | Dedicated, 10,000+ TPS capacity |
Data Privacy & Compliance | Fully transparent, on-chain data | Configurable privacy (ZK-proofs, private mempools) |
Regulatory Sovereignty | None; governed by public consensus | Full control over validator set & compliance rules |
Time to Production | Immediate deployment | 4-8 weeks for full customization & audit |
Integration Complexity | High (oracle reliance, bridge security) | Low (native API, direct fiat on/off-ramps) |
Total Cost of Ownership (Year 1) | $50K-$200K+ (gas, infrastructure, monitoring) | $150K-$500K (fully managed, predictable) |
Best For | Low-value, high-volume retail payments | High-value, compliance-heavy institutional settlements |
Our Delivery Process: From Specification to Mainnet
A structured, phased approach designed for institutional clients. We deliver a production-ready, compliant AppChain for payments in 8-12 weeks with full transparency at every milestone.
Phase 1: Discovery & Architecture
We conduct a 2-week technical deep-dive to define your payment flows, compliance requirements, and integration points. Deliverables include a detailed technical specification, tokenomics model, and a high-level architecture diagram.
Phase 2: Core Protocol Development
Our engineers build the custom consensus mechanism, payment settlement layer, and cross-chain bridges. All code follows enterprise-grade security patterns and is documented for your internal review.
Phase 3: Security & Compliance Audit
Mandatory, independent smart contract audit by a top-tier firm (e.g., Trail of Bits, Quantstamp). We also conduct internal penetration testing and produce a compliance gap analysis report for regulators.
Phase 4: Staging & Integration
Deploy your AppChain to a private testnet. We facilitate integration with your existing treasury systems, run load tests simulating 10k+ TPS, and conduct UAT with your team.
Phase 5: Mainnet Deployment & Handoff
Managed mainnet launch with validators, RPC endpoints, and block explorers. We provide comprehensive operational runbooks, monitoring dashboards, and 30 days of post-launch support.
Ongoing: Infrastructure Management
Optional managed service offering. We provide 24/7 monitoring, validator management, performance optimization, and protocol upgrade services backed by a 99.9% uptime SLA.
Frequently Asked Questions on Payment AppChains
Get clear answers on timelines, costs, security, and support for your institutional payment blockchain project.
From specification to mainnet launch, a standard deployment takes 4-6 weeks. This includes 1-2 weeks for architecture design and smart contract development, 2-3 weeks for core chain customization and integration, and 1 week for final testing and deployment. Complex multi-asset or cross-chain settlement systems may extend to 8-10 weeks. We provide a detailed project plan with weekly milestones upon engagement.
