Revoking mint authority and locking liquidity are two fundamental security practices for Solana token launches. However, token creators frequently confuse the two actions or assume that executing one automatically replaces the need for the other.
While both steps build investor trust, they protect two completely different parts of a project: Revoking Mint Authority controls token supply creation, while Locking Liquidity secures the underlying asset pool.
To launch a secure, rug-proof project on Solana, creators must execute both actions at the correct stages of their launch timeline.
Core Difference: Supply Control vs. Asset Security
The fundamental difference between these two actions lies in what on-chain asset they modify:
1. Revoking Mint Authority (Supply Protection)
- Target Asset: The SPL Token Mint Account.
- Action Taken: Permanently sets the token’s
mintAuthority address to null.
- What It Prevents: Prevents the creator or any private key from ever minting additional supply to dilute token value or flood the market.
- Protocol Impact: Fixes total token supply permanently on the Solana blockchain.
2. Locking Liquidity (Pool Asset Security)
- Target Asset: The DEX Liquidity Provider (LP) tokens received after creating a pool on Raydium or Orca.
- Action Taken: Deposits LP tokens into a verifiable, time-locked vault (or burns them to a null address).
- What It Prevents: Prevents the creator from withdrawing the SOL and token reserves from the liquidity pool (an action known as a liquidity rug pull).
- Protocol Impact: Guarantees trading liquidity remains accessible for buyers for the duration of the lock.
Protocol mechanisms for mint keys are detailed in the Solana SPL Token Documentation.
Execution Timing: When Should You Do Each Step?
Executing security steps in the correct sequence ensures a smooth, uninterrupted launch flow.
Execute: Revoke Mint Authority
Revoke mint authority right after minting your initial supply on PumpBolt Token Creator or via the PumpBolt Security Hub. Doing this before creating your liquidity pool signals to early security scanners that the token supply is capped.
Execute: Lock Liquidity
Once your DEX liquidity pool is initialized on Raydium or Orca, LP tokens arrive in your creator wallet. Immediately visit PumpBolt Lock Liquidity to lock or burn your LP tokens before sharing the pair link publicly.
Security Audit & DexScreener Badge Comparison
DEX aggregators like DexScreener, Birdeye, and RugCheck evaluate both parameters independently.
- Revoked Mint Badge: Granted when
mintAuthority is null. Displays a green checkmark confirming zero supply inflation risk.
- Locked LP Badge: Granted when LP tokens reside in a recognized vault program. Displays a green padlock confirming liquidity cannot be pulled.
If a project revokes mint authority but leaves liquidity unlocked, traders face the risk of a liquidity withdrawal. Conversely, if liquidity is locked but mint authority remains active, the creator could mint billions of new tokens and dump them into the pool.
