CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
We don't just write code; we engineer systems that are secure by default and built to last.
- Security-First Development: Code reviews, formal verification, and adherence to
OpenZeppelinstandards. - Full-Stack Integration: Contracts designed to work seamlessly with your frontend,
oracles, and wallets. - Post-Deployment Support: Includes monitoring, incident response, and upgrade management.

Architectural Comparison
Proof-of-Usage Protocol vs. Traditional Billing Methods
A technical breakdown of how on-chain usage metering and billing fundamentally differs from legacy subscription and SaaS models, highlighting key operational and financial advantages.
| Architectural Factor | Traditional SaaS/API Billing | Proof-of-Usage Protocol |
|---|---|---|
Billing Granularity | Fixed tiers or seat-based | Per-transaction or per-compute-unit |
Revenue Recognition | Manual, delayed reconciliation | Real-time, on-chain settlement |
Fraud & Dispute Risk | High (chargebacks, unpaid invoices) | Near-zero (pre-funded, non-custodial) |
Developer Integration | Complex API calls, webhooks, dashboards | Single smart contract call for payment & logic |
Time to First Payment | 30-90 days (net terms) | Instant (upon contract execution) |
Global Payouts | Complex, high-fee wire transfers | Native, permissionless crypto transfers |
Audit Trail | Centralized database logs | Immutable, verifiable blockchain ledger |
Custom Logic Support | Limited to vendor platform | Fully programmable (smart contracts) |
Typical Implementation Time | 2-4 weeks | 1-2 weeks |
Ongoing Operational Cost | 3-5% + platform fees | < 1% (gas costs only) |

METHODOLOGY
Our Protocol Design & Implementation Process
A systematic, security-first approach to designing and deploying robust Proof-of-Usage billing protocols. We translate your business logic into auditable, on-chain systems.
01
Requirements & Economic Modeling
We begin by mapping your business logic to on-chain mechanics, defining usage metrics, tokenomics, and incentive structures. This phase establishes the protocol's core economic security and sustainability.

Architecture & Smart Contract Design
Our architects design the system architecture, selecting optimal standards (ERC-20, ERC-1155) and patterns (pull vs. push payments, upgradeability). We produce detailed technical specifications and gas-optimized contract blueprints.

Proof-of-Usage Billing Protocol FAQ
Common questions from CTOs and product leads evaluating custom billing protocol development. Based on our experience delivering 20+ on-chain monetization systems.
A complete, audited Proof-of-Usage billing system typically takes 6-10 weeks from design to mainnet deployment. This includes 2 weeks for architecture and economic modeling, 3-4 weeks for core smart contract development, 2 weeks for internal and external security audits, and 1-2 weeks for deployment and integration support. For simpler integrations with existing protocols, timelines can be as short as 4 weeks.
