What Is Token Standard?
Definition
A token standard is a set of rules that defines how tokens work on a specific blockchain — SPL on Solana and ERC-20 on Ethereum are the two most common fungible token standards.
Token standards ensure interoperability — any wallet, DEX, or dApp that supports the standard can work with your token automatically, without custom integration.
- SPL Token (Solana) — Solana Program Library token. Supports mint/freeze authorities, Metaplex metadata.
- ERC-20 (Ethereum/Base) — Ethereum Request for Comment 20. The original smart contract token standard. Name, symbol, supply, transfer, approve.
- BEP-20 (BNB Chain) — identical to ERC-20 but on Binance Smart Chain.
- Token-2022 (Solana) — extended SPL with transfer fees, interest bearing, confidential transfers.
Why standards matter: a token following SPL or ERC-20 automatically works with Phantom/MetaMask wallets, Raydium/Uniswap DEXes, Jupiter/1inch aggregators, and CoinGecko/CoinMarketCap analytics. No custom code needed.
CoinDevTools creates standard SPL tokens (Solana) and ERC-20 tokens (Ethereum/Base) — guaranteed compatible with the entire ecosystem.

Token-2022 is Solana's next-generation token program that adds extensions like transfer fees, interest-bearing tokens, non-transferable tokens, and confidential transfers to SPL tokens.
Smart Contract
A smart contract is a self-executing program stored on a blockchain that automatically enforces the rules of an agreement when predefined conditions are met.
