Introduction
In the dynamic realm of cryptocurrency and blockchain technology, crypto tokens power most digital transactions and decentralized applications (dApps). These tokens adhere to specific token standards—rules governing their behavior, interoperability, and functionality within a blockchain ecosystem.
This guide explores crypto token standards like ERC20, BEP20, TRC20, and SPL, their significance, and how they vary across blockchains such as Ethereum, BNB Smart Chain, Tron, Solana, and Bitcoin.
Why Token Standards Matter
Token standards ensure:
- Interoperability: Seamless integration with wallets, dApps, and exchanges.
- Consistency: Uniform functionality across tokens.
- Security: Reduced vulnerabilities through proven frameworks.
Popular Token Standards by Blockchain
Ethereum (ETH) Standards
1. ERC20
- Type: Fungible.
- Features: Token transfers, balance checks, third-party approvals.
- Use Cases: Stablecoins (USDT, USDC), DeFi tokens.
2. ERC-721
- Type: Non-fungible (NFTs).
- Features: Unique token IDs, metadata.
- Use Cases: Digital art (Bored Ape Yacht Club), gaming assets.
3. ERC-1155
- Type: Hybrid (fungible + non-fungible).
- Features: Batch transfers, multi-token support.
- Use Cases: Gaming ecosystems (Enjin).
4. ERC-777
- Type: Fungible (advanced ERC20).
- Features: Enhanced interactions, backward compatibility.
- Use Cases: DeFi protocols.

- Features: Low fees, Binance ecosystem compatibility.
- Use Cases: PancakeSwap (CAKE), BUSD.
Tron (TRX) Standards
TRC20
- Type: Fungible.
- Features: Fast, low-cost transactions.
- Use Cases: USDT-TRC20.
Solana (SOL) Standards
SPL
- Type: Fungible/Non-fungible.
- Features: High-speed transactions.

FAQ
Q: Can I send ERC20 tokens to a BEP20 address?
A: No—use a cross-chain bridge to avoid losing funds.
Q: Which is cheaper: TRC20 or ERC20?
A: TRC20 offers lower fees on Tron compared to Ethereum’s ERC20.
Q: Does Bitcoin support token standards?
A: Bitcoin’s Ordinals protocol enables NFT-like assets, but native token standards are limited.
