What Is an SPL Token? Solana's Token Standard, Explained Simply
Bottom line: Solana's shared token standard
An SPL token is the common token standard on Solana (SPL = Solana Program Library). It is the equivalent of Ethereum's ERC-20: a shared framework that lets many different tokens work the same way. Stablecoins like USDC, memecoins, and project tokens are all issued as SPL tokens.
Key takeaways
SPL = Solana's shared token standard (like ERC-20). A single shared Token Program handles them, so wallets and DEXs can support a new token instantly. Issuing and transferring tokens is cheap and fast. Note: SOL itself is not an SPL token — it is the native currency (its SPL-token wrapper, Wrapped SOL, is a separate thing — see What Is Wrapped SOL (wSOL)?). New to Solana? Start with What is Solana.
How it works (in plain terms)
On Solana, creating, transferring, and tracking token balances is handled by one shared Token Program. Each user holds a "token account" per token, where their balance is recorded. Because the standard is shared, any compatible wallet or app can handle a brand-new token the same way it handles every other.
| Aspect | SPL token | For reference: ERC-20 (Ethereum) |
|---|---|---|
| Chain | Solana | Ethereum |
| Role | Common token standard | Common token standard |
| Fees | Very low | Can be high depending on congestion |
What is "Token-2022"?
Solana also has an extended version called Token-2022 (Token Extensions) that can add features such as transfer fees, interest, and transfer restrictions. Some assets — for example PayPal's PYUSD — use these extensions.
Things to watch out for
- Fake tokens and scams: many fakes impersonate the name of a real token. Verify the official mint address.
- Tokens that show up unrequested: never interact with airdrops you didn't expect — they are a common entry point for approval scams. See Solana scams: an overview.

FAQ
Q. Is SOL an SPL token? A. No. SOL is Solana's native currency and is handled differently internally from SPL tokens.
Q. How is it different from ERC-20? A. The role — a token standard — is the same, but the chain differs. Solana's fees are lower and transactions are faster.
