Witek Radomski

Led the technical implementation of Enjin's on‑chain infrastructure, producing the smart contracts and developer SDKs used to mint, lock and manage ENJ‑backed assets. Delivered the initial toolset that enabled game studios to integrate ENJ into in‑game economies and to programmatically bind ENJ as collateral for minted items, directly shaping on‑chain token utility and lifecycle. Played a central role in proposing and implementing the ERC‑1155 multi‑token standard that consolidated fungible and non‑fungible token handling into a single contract pattern and reduced transaction costs for complex asset bundles. Work on ERC‑1155 and the Enjin SDKs increased compatibility of ENJ with other Ethereum tooling and reduced friction for marketplaces and wallets to support ENJ‑backed NFTs. Architected technical aspects of subsequent infrastructure efforts including the Efinity design and cross‑chain bridges that sought to scale NFT throughput while preserving ENJ's role as an ecosystem utility. These codebases and standards decisions made by the CTO team are directly traceable to how ENJ is issued, transacted and supported across wallets and marketplaces.
