Smart contracts for
the agent economy.

AI agents that pay, trust, and hire each other — through smart contracts we write.

X402

HTTP-native micropayments — AI agents pay each other per API call. Built by Coinbase.

ERC-8004

Trustless AI agent identity — on-chain ID, reputation, and verification. Live on mainnet since Jan 2026.

ERC-8183

Agent-to-agent escrow — conditional payment for work between autonomous agents. Launched Mar 2026.

Our Insights

What we've built.

Not just code. Production-grade smart-contract systems that handle real value.

01/

DePIN node infrastructure

Decentralized GPU cloud infrastructure with 100,000 Checker Nodes sold on Arbitrum. We built the node sale contracts, staking mechanics with 4-year vesting, and the reward distribution system for node operators earning from 15% of total $ATH supply. The tier-based pricing and transfer-lock logic lived entirely on-chain.

02/

Asset tokenization platform

A multi-strategy RWA (Real World Asset) DeFi platform powered by the USHD stablecoin, offering institutional-grade access to real-world assets, sustainable yield, and growth opportunities. Helix provides a full-stack, omni-chain ecosystem for seamless DeFi composability, backed by U.S. T-Bills and top-rated money market instruments.

03/

stablecoin infrastructure

A full stablecoin from smart contracts to frontend. The peg mechanism, reserve management, and minting/burning logic — all in Solidity. We implemented ERC-2612 (permit) for gasless approvals so users could interact without holding ETH for gas.

04/

NFT node sale

Token-bound accounts (ERC-6551) for NFT node licenses — each NFT owns its own wallet, accumulates rewards, and can be transferred as a single unit. Compressed NFTs for gas-efficient minting at scale.

05/

post-TGE token infrastructure

Full token lifecycle after launch: ERC-20 with mint/burn/pause, time-locked staking with auto-compounding, on-chain governance (veTokens + delegation), and cross-chain bridge via LayerZero OFT. Buyback-and-burn mechanics and transfer fee distribution — all configurable by DAO vote.

06/

DeFi strategy vault

On-chain DeFi strategy execution — deposit, allocate, and harvest yield through smart contracts. Custom vault logic with strategy parameters controlled by the deployer. Clean separation between vault (holds funds) and strategy (executes trades).
