Cross-Chain Token Standards ÔÇö Token Standards Index
Token standards define how digital assets behave on a blockchainÔÇöincluding how they are transferred, stored, and interacted with by smart contracts. These standards create consistency across wallets, dApps, and exchanges, enabling broader interoperability and developer adoption.
Use Case: Token standards ensure that fungible and non-fungible tokens follow a shared set of rules, making them universally usable across tools and platforms.
Key Concepts:
- ERC-20 ÔÇö Standard for fungible tokens on Ethereum.
- NFT Standards ÔÇö Protocols for unique, non-fungible assets (e.g., ERC-721, XLS-20).
- Fungibility ÔÇö Whether tokens are interchangeable or unique.
- Token Interoperability ÔÇö Seamless use across chains and platforms.
- Blockchain Ecosystems ÔÇö Networks where token standards are implemented.
Summary: Token standards provide the foundation for digital asset compatibility, security, and widespread adoption. They enable innovation and liquidity across the global Web3 landscape.
Major Token Standards by Blockchain:
- Ethereum
- ERC-20 ÔÇö Standard for fungible tokens (e.g., $USDC, $UNI)
- ERC-721 ÔÇö Non-fungible token (NFT) standard (e.g., CryptoPunks)
- ERC-1155 ÔÇö Multi-token standard (both NFTs and fungibles, e.g., gaming assets)
- XRPL (XRP Ledger)
- IOU Format ÔÇö Issued currencies using trust lines (e.g., $BAD, $KAG)
- XLS-20 ÔÇö XRPL-native NFT standard
- Solana
- SPL ÔÇö Fungible and non-fungible token standard for Solana-based dApps
- Binance Smart Chain
- BEP-20 ÔÇö BinanceÔÇÖs equivalent of ERC-20 (e.g., $CAKE, $BUSD)
- BEP-721 / BEP-1155 ÔÇö NFT and multi-asset standards similar to Ethereum
- Flare / Songbird
- ERC-20 Compatible ÔÇö Flare uses Ethereum-compatible standards for DeFi tokens (e.g., $sFLR, $EXFI)
- Cardano
- Native Multi-Asset Standard ÔÇö Tokens are built at the protocol level without smart contracts
Why Token Standards Matter:
- Allow wallets and exchanges to support a wide range of tokens easily
- Define consistent behaviors for security, transfers, and metadata
- Enable smart contracts to trustlessly interact with tokens
- Separate the concept of fungibility, ownership, and supply control
