API Rate Limiting via Micropayments

We build API management systems where rate limits are dynamically enforced via Bitcoin micropayments. Users pay for increased access in real-time, enabling usage-based monetization and efficient resource allocation.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

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 application. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security and gas efficiency from day one.

  • Full Lifecycle Support: From initial design and audit preparation to mainnet deployment and upgrade management.
  • Protocol Specialization: ERC-20, ERC-721, ERC-1155, custom DeFi logic, DAO governance, and cross-chain bridges.
  • Guaranteed Quality: Every contract undergoes rigorous unit testing and is structured for future-proofing via upgradeable proxy patterns.

Move from concept to a secure, audited mainnet deployment in as little as 4-6 weeks.

We translate your business logic into robust on-chain code, providing:

  • Comprehensive Documentation & Comments for your team and future auditors.
  • Deployment Scripts & Verification on Etherscan and other block explorers.
  • A clear handoff with knowledge transfer to your internal engineering team.

API Rate Limiting via Micropayments

Frequently Asked Questions

Get clear answers on how our token-gated API infrastructure works for your project.

Our system uses a token-gated architecture. Instead of traditional API keys with hard limits, users pay a small, configurable fee in your native token (or a stablecoin) for each API call. This creates a direct, verifiable cost-per-request model. You set the price per endpoint, and users' wallets are debited automatically. This eliminates abuse, ensures fair usage, and creates a new revenue stream for your service.
