overview
RELIABLE FOUNDATION

Blockchain Infrastructure for FinTechs

Enterprise-grade node infrastructure with 99.9% uptime SLA for payment and trading applications.

We provide fully managed, multi-chain RPC nodes and indexers, eliminating the operational overhead of running your own infrastructure. This ensures your core team can focus on product development, not node maintenance.

Deploy production-ready infrastructure in days, not months, with predictable, usage-based pricing.

  • High Availability: Geo-distributed nodes across EVM, Solana, and Cosmos chains with automatic failover.
  • Performance Guarantees: Sub-100ms response times and 99.9% uptime SLA backed by real-time monitoring.
  • Security & Compliance: SOC 2 Type II compliant infrastructure with dedicated VPCs and role-based access control.
  • Developer Experience: Seamless integration with ethers.js, viem, and comprehensive API documentation.

PROVEN FRAMEWORK

Our Delivery Methodology

We deliver production-ready L2 bridges using a structured, security-first process that reduces time-to-market and technical risk for your project.

01

Architecture & Design Sprint

We begin with a collaborative workshop to define your bridge's core architecture—choosing between optimistic, zk-rollup, or sidechain models—and finalize token standards (ERC-20, ERC-721) and fee mechanisms.

Smart Contract Development

Our team writes, tests, and optimizes the core bridge contracts in Solidity/Vyper. We implement battle-tested patterns from OpenZeppelin and focus on gas efficiency for end-users.

Security & Audit Integration

Security is non-negotiable. Every bridge undergoes rigorous internal review followed by a formal audit from a top-tier firm like CertiK or Quantstamp before mainnet deployment.

CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts for tokens, DeFi protocols, NFTs, and DAOs. Our development process is built on OpenZeppelin standards and rigorous security practices, ensuring your logic is both powerful and protected.

  • Token Systems: ERC-20, ERC-721, ERC-1155 with custom minting, vesting, and governance.
  • DeFi Logic: Automated market makers, staking pools, yield aggregators, and lending protocols.
  • Security First: Every contract undergoes multi-stage audits and formal verification before mainnet deployment.
  • Full Ownership: You receive complete source code, documentation, and deployment scripts.

Move from concept to a live, audited contract in as little as 2-4 weeks. We handle the complex engineering so you can focus on your product.

Frequently Asked Questions

Get clear answers on timelines, security, and support for our enterprise-grade token bridge development service.

A standard, production-ready L2 token bridge deployment takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, security audits, and integration with your frontend. Complex multi-chain bridges or custom features like permissioned access can extend this to 6-8 weeks. We provide a detailed project plan with milestones during the initial consultation.
