How to Make a Solana Token Immutable
Lock your token's name, symbol, image, and description forever. This proves to holders that the token's identity can never be changed.
This action is irreversible
Once immutable, the token's metadata can never be updated — not even by the creator. Double-check everything before confirming.
Step-by-step
Finalize your metadata
Before making immutable, ensure your token's name, symbol, image URL, and description are exactly how you want them. Once immutable, these can NEVER be changed — not by you, not by anyone.
Connect your wallet
Go to CoinDevTools and connect the wallet that has update authority over the token. This is usually the wallet that created the token.
Enter your token address
Paste your SPL token's mint address into the Make Token Immutable tool. The tool verifies you have update authority.
Confirm the transaction
Review the warning — this action is irreversible. Click confirm and approve the wallet transaction. The Metaplex metadata account's isMutable flag is set to false permanently.
Verify on Solscan
Check your token on Solscan. The metadata should now show "Mutable: No" — proving to anyone that the token's branding is locked forever.

What does "immutable" mean for a Solana token?
It means the Metaplex token metadata (name, symbol, image, description) can never be changed again. The isMutable flag is set to false permanently. This is separate from revoking mint or freeze authority — those control supply and transfers, while immutability controls the token's identity.
Should I make my token immutable before or after launch?
After you've finalized everything. Make sure the name, symbol, and image are correct first. Many creators finalize metadata, then make immutable, then revoke authorities, then create the pool — in that order. Once immutable, you cannot fix typos in the token name.
Is making a token immutable free?
Yes. The CoinDevTools Make Token Immutable tool is free. You only pay the Solana network fee (under $0.01).
Does this work for ERC-20 tokens on Ethereum/Base?
No — immutability is a Solana-specific concept via Metaplex. ERC-20 tokens on Ethereum/Base don't have on-chain metadata in the same way. The equivalent trust signal on EVM chains is renouncing contract ownership.
