Enjin Platform Glossary

Learn more about common Enjin Platform Terms.
Here's a list of Common Enjin Platform-related terms used in the space that should come in handy while interacting with the Enjin Platform and with Blockchain as a whole.

Enjin Platform

The Enjin Platform is a blockchain PaaS (Platform as a Service) that allows you to create and manage blockchain games without the complexity of building and maintaining the infrastructure typically associated with developing and launching a blockchain game.

Wallet Daemon

The Wallet Daemon is a tool that you can use to automate the authorization of transaction requests to and from the Enjin Platform.
Without the Wallet Daemon, you would need to sign (authorize) every in-game blockchain transaction via the Enjin Wallet (e.g., sending a sword to a player).
Wallet Daemon manages an Ethereum address linked to an Enjin Platform identity. When a transaction is submitted on the Enjin Platform, the Wallet Daemon receives that transaction signs it, and sends it back to the Enjin Platform.


A query is a special type of object that clients can execute against a server to return information like a list of addresses or tokens available in the Enjin Platform.


A mutation is similar in structure and purpose to the queries. Whereas the query type defines entry points for read operations, the Mutation type defines entry points for write operations like creating, minting, and setting metadata to a token in the Enjin Platform.


GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data.

GraphiQL Playground

GraphQL Playground is a graphical, interactive, in-browser GraphQL IDE, created by Prisma and based on GraphiQL. It's used by the Enjin Platform as a way to improve the experience of developers while interacting with the Enjin Platform before heading towards a software-based GraphQL IDE.

Platform Schema

The Enjin Platform Schema is a set of parameters and variables that can be processed by the GraphQL language for devs to integrate the Enjin Platform into their projects with ease.

Wallet App

The Enjin Wallet is a secure, feature-packed, and convenient cryptocurrency and blockchain asset wallet built for traders, developers, and gamers.


Is a suite of integrated products that make non-fungible tokens (NFTs) easy for individuals, businesses, and developers.


JumpNet is a private (PoA) method of consensus blockchain that allows instant and gasless transactions on-chain.


Enjin Coin (ENJ) is an Ethereum-based cryptocurrency used to back the value of next-gen fungibles and NFTs.


JENJ is the Jumpnet version of ENJ tokens.


Efinity is a scalable, decentralized, and cross-chain token infrastructure built to enable users, developers, and enterprises to harness NFTs with zero friction. Built on Polkadot, Efinity will serve as the infrastructure for the decentralized, cross-chain Metaverse.


EFI is based on the Paratoken Standard, a new standard for interoperable, cross-chain tokens—across the entire Polkadot ecosystem, and even external blockchains. EFI is the core utility token on Efinity—it's used to pay for transferring, bridging, and trading tokens. Everyone who participates in the Efinity network—from collators who help maintain it, to users who trade or bid on NFTs—is rewarded with EFI.


The Goerli Blockchain is a PoA (Proof-of-Authority) public testing blockchain, created and maintained by a consortium of Ethereum Developers to assist the Ethereum development community.


The concept of Metadata applied in blockchain for NFTs is the content and description of the content stored on an NFT in the blockchain, it can be used to refer to a file that will give a name, description, image and attributes to an FT or NFT.


The InterPlanetary File System is a protocol and peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting all computing devices.


The Term Platform refers to the Enjin Platform, which is a service that allows you to create and manage blockchain games without the complexity of building and maintaining the infrastructure typically associated with developing and launching a blockchain game.

Token ID

Token ID is a numerical identifier generated by the Enjin Platform to differentiate tokens and make sure tokens are unique and traceable within the Enjin Ecosystem.

Token Index

A token Index is also a numerical identifier exclusive to NFTs, which is generated by the Enjin Platform to differentiate NFTs that were created under the same Token ID.


Minting is the process of creating blockchain assets infused with Enjin Coin (ENJ).


Melting is the process of destroying a blockchain asset to retrieve the ENJ from within. The percentage of ENJ a user can retrieve by melting an item can be between 50% and 100%. This value is determined by the developer, who receives the remainder of the melted value (the melt fee).
