How to Revoke Token Authority
Revoking authority is how you prove your token is decentralized. This guide covers all three types: mint authority, freeze authority, and contract ownership.
Mint Authority
Controls token supply. Revoke to lock supply permanently.
Solana only
Freeze Authority
Can freeze any wallet. Revoke to guarantee free transfers.
Solana only
Contract Owner
Admin role on ERC-20. Renounce to fully decentralize.
Ethereum / Base
Step-by-step
Understand the three authority types
On Solana, tokens have a mint authority (can create new tokens) and a freeze authority (can freeze wallets). On Ethereum/Base, the "owner" role controls contract admin functions. Revoking each is a separate, irreversible action.
Connect your wallet
Go to CoinDevTools and connect the wallet that created the token. You must be the current authority holder to revoke it.
Revoke mint authority (Solana)
Navigate to the Revoke Mint Authority tool, enter your token's mint address, and confirm. After this transaction, no wallet can ever mint new tokens — supply is permanently fixed.
Revoke freeze authority (Solana)
Navigate to the Revoke Freeze Authority tool. After revoking, no wallet can ever be frozen for your token — all holders can always transfer freely.
Renounce ownership (Ethereum/Base)
Navigate to the Renounce Ownership tool for your chain. This sets the contract owner to the zero address — no one can change any contract parameters ever again.
Verify on-chain
Check Solscan (Solana), Etherscan (Ethereum), or Basescan (Base) to verify the authority has been revoked. The blockchain record is your proof of decentralization.

FAQ
Can I undo revoking authority?
No. Revoking mint authority, freeze authority, or renouncing ownership is permanent and irreversible. This irreversibility is the entire point — it cryptographically proves that no one can change the token's rules.
Should I revoke all authorities at once?
It depends on your project. For memecoins and community tokens, revoking all authorities before launch is standard practice. For utility tokens or projects that may need to update metadata, you might keep some authorities temporarily. At minimum, revoke mint authority to lock supply.
What does "make token immutable" mean?
On Solana, making a token immutable means setting the Metaplex metadata's isMutable flag to false. After this, the token's name, symbol, image, and description can never be changed. It's a separate action from revoking mint/freeze authority.
Is revoking authority free?
On CoinDevTools, all authority revocation and ownership renouncement tools are free to use. You only pay the blockchain gas fee, which is under $0.01 on Solana and varies on Ethereum/Base.
