Institutional Cross-Chain L2 API

A secure, compliant API layer enabling financial institutions to programmatically manage and transfer assets across multiple Layer 2 networks with built-in regulatory controls and reporting.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 experts to power your decentralized application.

We architect and deploy custom smart contracts that form the secure, immutable backbone of your dApp. Our development process ensures gas-optimized code and comprehensive security audits before mainnet deployment.

  • Custom Logic: Build ERC-20, ERC-721, ERC-1155, and bespoke token standards.
  • Security First: Development follows OpenZeppelin patterns and undergoes formal verification.
  • Full Lifecycle: From initial design and Solidity 0.8+ development to deployment and upgrade management via Transparent Proxy patterns.

Deploy a battle-tested, audited smart contract suite in as little as 2-4 weeks, reducing your technical risk and accelerating your product launch.

Institutional Cross-Chain L2 API

Frequently Asked Questions

Get clear answers on how our API delivers secure, low-latency cross-chain liquidity for institutional applications.

Our API is engineered for institutional speed. We deliver sub-2-second finality for asset transfers between supported L2s and EVM chains. For complex cross-chain smart contract calls, typical latency is under 5 seconds. This is achieved through our proprietary message-passing layer and direct integration with rollup sequencers.
