BUILT FOR ENTERPRISE
Core Technical Capabilities of Your Payment Guarantee Chain
We deliver a production-ready Substrate parachain with enterprise-grade security, interoperability, and compliance features designed for real-world payment guarantees.
01
Custom Substrate Runtime
We build a purpose-built runtime for your payment guarantee logic using FRAME pallets. This includes custom modules for escrow management, dispute resolution, and automated settlement, ensuring your business rules are encoded directly into the chain's state transitions.
FRAME v2
Runtime Framework
Rust
Core Language
02
Cross-Chain Asset Transfers (XCMP)
Enable seamless, trust-minimized movement of assets between your parachain and other Polkadot/Kusama parachains. This allows you to accept payments in multiple native assets and settle guarantees across ecosystems without centralized bridges.

03
Enterprise-Grade Security & Audits
From pallet logic to runtime upgrades, every component undergoes rigorous security review. We implement best practices from OpenZeppelin and leverage formal verification tools for critical state transitions, delivering a chain you can trust with high-value transactions.

Strategic Infrastructure Decision
Build a Parachain vs. Using a Shared Smart Contract Platform
Choosing the right foundation for your Web3 payment system involves critical trade-offs. This table compares the core operational, financial, and technical implications of building a custom Polkadot parachain versus deploying on a shared smart contract platform like Ethereum L2 or Solana.
| Decision Factor | Build a Custom Parachain | Use a Shared Smart Contract Platform |
|---|---|---|
Time to Production Launch | 8-16 weeks | 2-4 weeks |
Upfront Development Cost | $150K - $400K+ | $25K - $75K |
Sovereignty & Customization | Full control over chain logic, governance, and fee model | Limited to VM constraints; subject to platform upgrades and fees |
Transaction Throughput & Finality | 1,000 - 10,000+ TPS; ~6-12 second finality via Polkadot | 10 - 100 TPS (EVM); 2,000 - 50,000 TPS (Solana); Variable finality |
Cross-Chain Interoperability | Native via XCMP (Polkadot ecosystem) | Requires third-party bridges (security risk) |
Security Model | Shared security from Polkadot Relay Chain validators | Inherits security of the host chain (e.g., Ethereum) or its validator set |
Ongoing Operational Burden | High (node ops, upgrades, consensus management) | Low to None (managed by the platform) |
Ideal Use Case | High-frequency payments, unique consensus, regulatory compliance needs | Rapid prototyping, asset issuance, applications leveraging existing DeFi liquidity |
