CRUST20

CRUST20 is a fungible token standard implemented on the CRUST network, a decentralized storage platform built on Substrate. It is designed to provide a uniform token interface for paying storage fees, rewarding storage providers, and participating in network governance. CRUST20 is inspired by common fungible token patterns but is tailored to the Substrate-based environment and the specific economic design of the CRUST ecosystem.

Technical foundations and interface

CRUST20 defines a standard set of on-chain functions for fungible tokens, including querying total supply, checking balances, transferring tokens, approving transfers on behalf of others, and executing delegated transfers. It typically includes events for transfers and approvals and stores balances and allowances in runtime state. The standard supports metadata such as token name, symbol, and decimal precision, and is implemented as a runtime module (pallet) that can be upgraded within the governance framework of the CRUST chain.

Economic design and use cases

The primary use cases for CRUST20 are to pay for decentralized storage services and to compensate storage providers within the CRUST ecosystem. The token can also serve in governance processes, enabling holders to participate in decisions about protocol upgrades and parameter adjustments. Token supply mechanics, minting, burning, and distribution rules are managed by the CRUST governance process and related economic policies.

Interoperability and adoption

CRUST20 aims for broad compatibility within the Substrate ecosystem and cross-chain assets via bridges or interoperability layers. Wallet support, exchanges, and tooling typically integrate CRUST20 similarly to other fungible assets, enabling users and providers to manage balances and participate in the network economy.
