Glossary

This page provides unified explanations for frequently occurring terms that appear across multiple chapters. When reading Chapters 26-35 and Examples 11-18, use this page as a quick reference guide.

AdminACL

An authorization control object for server-side access in World contracts. The game server or Builder backend writes approved sponsor addresses into AdminACL, and on-chain logic verifies whether the caller has “server representative” identity through validation functions like verify_sponsor.

OwnerCap

An ownership credential for objects or structures. Many World-side permission checks don’t just look at ctx.sender(), but require the caller to explicitly hold an OwnerCap associated with the target object.

AdminCap

An admin capability object within a Builder’s own module. It’s typically issued to the publisher during init and used to configure settings, modify rules, pause functionality, or withdraw funds.

Typed Witness

A pattern that uses the type system to tighten authorization boundaries. EVE Frontier’s Gate / Turret / Storage Unit extensions often use it to restrict “only specific modules and specific entry points” from calling sensitive APIs.

Shared Object

A shared object on Sui that can be concurrently accessed by multiple parties. World structures like Gates, Storage Units, and Registries often adopt this model.

Derived Object

An object ID deterministically derived from a parent object and business key. Scenarios like KillMail and registry sub-objects use this to ensure the business ID -> on-chain object ID mapping is stable and non-repeatable.

Sponsored Transaction

A transaction initiated by a player but with Gas paid by the Builder or server. EVE Vault supports sponsored transaction extensions, which is the core foundation for “users can use dApps without SUI”.

zkLogin

Sui’s passwordless login solution. After users complete OAuth login with their Web2 identity, the wallet derives the on-chain address based on ephemeral keys, salt, and proof.

Epoch

Sui’s epoch unit. zkLogin’s temporary proofs and certain caches are bound to Epochs, requiring reissuance or login state refresh after expiration.

0x6

The fixed object ID for Sui’s Clock system object. Many time-related examples in this course pass 0x6 as a parameter.

0x8

The fixed object ID for Sui’s Random system object. Examples requiring on-chain randomness typically pass this object.

LUX and SUI

Many examples in this course “use SUI instead of LUX for demonstration” to facilitate explanation in public environments and with standard SDKs. When actually integrating with EVE Frontier, use the in-game real assets and World/wallet interfaces as the standard.

GraphQL / Indexer

GraphQL mentioned in this book mostly refers to the query endpoints provided by Sui’s indexing layer; Indexer refers to off-chain retrieval services built around events and object state. They are primarily responsible for “reads”, not “writes”.
