Onchain Development
Build onchain.
Ship with confidence.
Smart contracts, stablecoin settlement, agent wallets, and DeFi infrastructure. We build the onchain layer for your business.
Capabilities
End-to-end expertise
Smart Contract Engineering
Code that holds value
Production-grade Solidity contracts with full test coverage, gas optimization, and formal verification. Deployed across EVM-compatible chains.
Stablecoin Integration
Payments that settle
USDC and USDT payment flows, treasury operations, and settlement infrastructure. Fiat on/off ramps with compliance-ready architecture.
x402 Protocol Implementation
HTTP-native payments
HTTP-native payment infrastructure. Servers that accept stablecoin payments at the protocol layer. Pay-per-request APIs and micropayment architecture.
Agent Wallet Infrastructure
Autonomous economic agents
Autonomous wallets for AI agents with programmable spending policies, per-task budgets, and full audit trails. The economic layer for agentic systems.
DeFi Protocol Development
Composable financial primitives
Liquidity pools, yield strategies, lending protocols, and automated market makers. Built for security, composability, and real economic utility.
Token & Asset Architecture
Assets designed to last
Token design, smart contract deployment, and asset management systems. From fungible tokens to NFTs to IP rights tokenization.
