CAP-20
CAP-20 (Chiliz Advancement Proposal 20) explained: Chiliz Chain's ERC-20 equivalent token standard used for Fan Tokens, which use 18 decimals following the 2026 Decimal Fan Token migration.
What is CAP-20?
In the blockchain world, xxx-20 refers to token standards inspired by Ethereum's ERC-20 standard. For instance, BEP-20 is the standard token for BNB Smart Chain (BSC), and likewise, CAP-20 is the equivalent of ERC-20 for Chiliz Chain.
First, what is ERC-20?
ERC-20 is the most common token standard on the Ethereum blockchain.
A token standard is a set of rules that tokens must follow to work properly on a blockchain. These rules include how the tokens can be transferred/spent, how transactions are approved, how users can access data about a token, and the total supply of the token.
Following ERC-20 ensures that different tokens can interact with each other in a predictable way on Ethereum, making it easier for developers to create new tokens that will work well with wallets, exchanges, and other smart contracts.
In simple terms, ERC-20 is like a common language that all tokens on the Ethereum network use to understand each other and work together smoothly.
Now, what is CAP-20?
CAP-20 is the standard for Fan Tokens on Chiliz Chain.
While it follows the ERC-20 basic features, it also extends it to support a wider range of tokens.
Fan Tokens (or "CAP-20 tokens") are essentially ERC-20 tokens, but:
They run on Chiliz Chain, not Ethereum,
Therefore they use $CHZ, not $ETH.
Like ERC-20, CAP-20 tokens use 18 decimals of precision, so balances, transfers, and total supply are denominated in the token's smallest unit and support fractional ownership.
Tokens created on different blockchain platforms can be adjusted or linked to Chiliz Chain through a process called bridging. Learn more about Chiliz Bridge.
