Mythical Games

Mythical Games is a Web3 game-technology studio and platform company (an a16z portfolio company) that builds games with player-owned digital items and a secondary marketplace economy. Its business has two sides: consumer game titles (FIFA Rivals, Pudgy Party, Blankos) and the Mythical Platform, a B2B toolkit that lets any game add a secondary economy of tradeable items and currencies. The platform is exposed to integrating studios primarily through gRPC/Protobuf SDKs — the Saga SDK and the earlier IVI SDK — published for Java, C++, and Python, rather than a public REST/OpenAPI surface. The Saga gRPC API covers items, item types, currencies, currency types, listings, offers, player wallets, reservations, an NFT bridge, and metadata, with cursor-based queries and a server-streaming status channel for confirming asynchronous writes. Assets settle on the Mythos chain, a Polkadot/Substrate gaming parachain (MYTH token) whose node software is open source.

Mythical Games publishes 1 API on the APIs.io network. Tagged areas include Company, Gaming, Web3, Blockchain, and Digital Assets.

Mythical Games’ developer surface includes authentication, engineering blog, and 20 more developer resources.
