Wallet-as-a-Service (WaaS) API Platform

A fully managed API platform that handles all wallet infrastructure—key generation, custody (non-custodial or MPC), transaction signing, and recovery—allowing companies to embed blockchain wallets into their apps without managing private key security.

CORE SERVICE

Smart Contract Development

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

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process ensures security-first design, gas optimization, and comprehensive audit readiness from day one.

  • Full lifecycle development: From initial concept and Solidity/Rust coding to deployment on EVM/Solana/Cosmos chains.
  • Security as standard: Contracts are built using OpenZeppelin libraries and follow industry best practices to mitigate reentrancy, overflow, and access control vulnerabilities.
  • Deliverables include: Verified source code, deployment scripts, technical documentation, and a detailed security review report.

Move from idea to a live, auditable contract in as little as 2-4 weeks for an MVP.

Our engineers specialize in key contract types:

  • Token Standards: Custom ERC-20, ERC-721, ERC-1155 with minting, vesting, and governance modules.
  • DeFi Primitives: Automated Market Makers (AMMs), lending/borrowing pools, staking contracts, and yield aggregators.
  • Utility & Governance: Multi-signature wallets, DAO frameworks, and custom business logic for NFTs and marketplaces.
