How to Lock Liquidity on Solana — Burn vs Lock

To lock liquidity on Solana, you have two options: burn LP tokens (permanent, irreversible) or use a time-locked vault (temporary, unlocks after a set period). Burning is stronger for trust because it is permanent. Use SolTokenCreator.io/burn-lp-tokens to do either. Note that Raydium's Burn & Earn does not destroy anything despite the name: it moves a CPMM position into a lock program and mints you a Fee Key NFT, so the liquidity can never be withdrawn while the trading fees stay claimable by whoever holds that NFT.

Why Lock Liquidity?

Liquidity locking protects your community from rug pulls. Without locked liquidity, the pool creator can withdraw all tokens and SOL from the liquidity pool at any time, leaving holders with worthless tokens.

When liquidity is locked:

• Holders know the pool will continue functioning
• DexScreener displays the lock/burn status
• RugCheck gives a positive safety score
• Traders are more willing to buy

Burn vs Lock: Which Is Better?

| Feature | Burn LP Tokens | Time-Lock Liquidity | |---------|---------------|-------------------| | Duration | Permanent (forever) | Temporary (set period) | | Reversible | No | Yes (after lock expires) | | Trust level | Highest | High (but expires) | | DexScreener display | "Burned" badge | "Locked until [date]" | | RugCheck score | Best | Good | | Earn fees after | Yes (with Burn & Earn) | Depends on platform | | Cost | Network fee only | Varies by platform | | Best for | Meme coins, community tokens | Projects needing future flexibility |

When to Burn

Burning LP tokens is recommended when:

• You are launching a meme coin and want maximum trust
• You never plan to remove liquidity
• You want the strongest possible DexScreener badge
• You want to earn fees from locked liquidity (Burn & Earn)
• Your community expects permanent liquidity commitment

When to Time-Lock

Time-locking is better when:

• You may need to adjust liquidity later (e.g., migrate to a different pool)
• Your project has a planned token migration or upgrade
• You want temporary trust while keeping future options open
• Regulatory requirements may change your liquidity needs

How to Burn LP Tokens (Permanent Lock)

1. Create your token on SolTokenCreator.io
2. Create a Raydium liquidity pool
3. Go to Burn LP Tokens
4. Select your LP position
5. Click Burn and approve the transaction
6. Verify on DexScreener and RugCheck

With Burn & Earn, nothing is burned: the LP tokens move into Raydium's lock program and you keep earning trading fees from the locked position through the Fee Key NFT it mints you. Burn & Earn is Raydium's own program, not something exclusive to any front end, and it covers CPMM pools only — AMM V4 positions can be burned but not locked. Both paths are on the same page here, which is the part that is not standard.

How Much Liquidity Should You Lock?

| Percentage | Trust Signal | Common For | |-----------|-------------|-----------| | 100% | Maximum trust | Meme coins, fair launches | | 90-99% | Very strong | Projects keeping small operational reserve | | 50-89% | Moderate | Projects with planned liquidity expansion | | Under 50% | Weak | Considered insufficient by most traders |

For meme coins, 100% is the community expectation. For utility tokens with operational needs, 80-95% is acceptable.

Verifying Locked Liquidity

After locking, verify through these platforms:

DexScreener: Search your token. The liquidity section shows burn/lock percentage. Burned LP displays differently from locked LP — burned is permanent, locked shows an unlock date.

RugCheck: Enter your token's contract address. RugCheck analyzes liquidity lock status and includes it in the overall safety score.

Birdeye: Displays pool information including liquidity lock status.

Solana Explorer: Search the burn transaction to verify it contains a Burn instruction and that the LP token's total supply decreased — there is no recipient address to check, since burned tokens are destroyed rather than transferred.

Common Mistakes

1. Not locking liquidity at all — The biggest red flag for traders
2. Locking too little — Under 80% is considered weak
3. Short lock periods — 30-day locks barely register as trust signals
4. Forgetting to lock before promoting — Lock before your first marketing push
5. Using an unknown locking platform — Stick to proven methods like burning

Next Steps

Ready to lock your liquidity? The strongest method is burning LP tokens:

1. Create Liquidity Pool — Set up your Raydium pool
2. Burn LP Tokens — Permanently lock with Burn & Earn
3. Verify on DexScreener — Confirm the badge appears
