CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155contracts with advanced features like vesting, staking, and governance. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, and yield aggregators with sub-second finality.
- Enterprise Logic: Custom business logic for supply chain, identity, and asset tokenization on EVM and Solana.
We deliver a fully audited, deployable contract suite in 2-4 weeks, with a 99.9% uptime SLA for live protocols.

INTEGRATION FRAMEWORKS
Platforms We Enable
Our modular on-chain identity verification service integrates directly into your core platform, eliminating the need for custom middleware. We provide SDKs and APIs for the most common Web3 development stacks.

Frequently Asked Questions
Get clear, technical answers about our identity verification service, from deployment to security.
Our service provides a modular, API-first identity layer for Web3 applications. We handle the off-chain KYC/AML verification (leveraging certified providers) and issue a non-transferable, revocable Soulbound Token (SBT) or Verifiable Credential (VC) to the user's wallet. Your dApp simply checks for a valid credential on-chain to gate access, airdrops, or features. This decouples complex compliance from your core smart contract logic.
