Build the product around ownership.
Blockchain systems with a useful purpose, from digital assets to payments and connected applications.
Start a projectWhat we do
Considered from every angle.
We help teams decide where blockchain belongs in a product, then design and build the contracts, backend and user experience together. Our technical range includes EVM chains and Solana, DeFi, tokenised assets and NFT applications.
Smart contracts
Contract design, implementation and testing, including Solidity, Hardhat and ERC-20, ERC-721 and ERC-1155 token standards.
DApps & wallet integration
Wallet connection, signing and transaction flows linked to a usable web or mobile application, including Ethers.js, Viem and Wagmi integrations.
Tokenomics & protocol design
Technical modelling of issuance, vesting, staking, incentives and liquidity mechanisms, with clear assumptions and administrative controls.
Programmable payments
Stablecoin payments, shared-wallet permissions and paid API access, including x402 payment flows and revenue splitting.
Marketplaces & tokenised assets
Minting, listings, digital collectibles and real-world asset workflows connected to the product’s ownership and access requirements.
Privacy & trading infrastructure
Encrypted storage, wallet-based access, non-custodial product architecture and integrations for exchanges and automated liquidity strategies.
How we work
Close collaboration. Better decisions.
We define the ownership model, permissions and transaction flows before implementation. Contract testing, deployment planning and coordination with independent reviewers form part of the agreed delivery scope.
