Cross-Chain Payment Gateway Bridge

We develop and deploy secure, merchant-ready bridge infrastructure that enables instant, low-cost cross-chain settlements for e-commerce platforms and traditional payment processors.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 specialists.

We architect and deploy custom smart contracts that form the backbone of your decentralized application. Our development process is built on security-first principles, utilizing OpenZeppelin libraries, comprehensive unit testing, and multi-stage audits to ensure robustness.

  • Token Standards: ERC-20, ERC-721, ERC-1155, and custom implementations.
  • Protocol Logic: DEXs, staking, governance, vesting, and multi-signature wallets.
  • Deployment & Verification: Full deployment pipeline with Hardhat or Foundry, and source code verification on Etherscan/Snowtrace.
  • Gas Optimization: Code reviews focused on minimizing transaction costs for end-users.

We deliver audited, battle-tested contracts that reduce your time-to-market and mitigate critical security risks.

Our standard deployment follows a structured 4-phase process, typically completing in 3-5 weeks.

  1. Architecture & Scoping (1 week): We analyze your requirements and design the optimal bridge architecture (e.g., lock-and-mint, liquidity pool).
  2. Core Development (2-3 weeks): Our team builds and unit-tests the smart contracts, relayer infrastructure, and admin dashboard.
  3. Security Audit & Testing (1 week): The system undergoes internal review and a formal audit by our security partners.
  4. Deployment & Handover (3-5 days): We deploy to mainnet, conduct final integration tests, and provide comprehensive documentation.

For complex multi-chain integrations, timelines may extend to 6-8 weeks.
