How to Revoke Mint Authority.

Yeah, me too. I was in your shoes last year with this meme coin I threw together. Pumped out a million tokens, listed it, and then holders started asking in the Telegram: "You gonna rug us or what?" Revoking mint authority fixed that noise real quick. It's like flipping a switch that says, "No more infinite printing press, fam." Your supply's locked forever. No one can mint extras and dump. Trust skyrockets. Price holds better. Why does this matter? Because in Solana land, live mint auth = red flag for rugs.

So you're here to learn how. Good call. I'll walk you through it like we're grabbing coffee and I'm showing you on my phone. We've got no code tools mostly, 'cause who wants to code when Phantom wallet pops up and it's done? But I'll throw in a code option if you're feeling dev y. Costs like 0.01 SOL tops, gas is negligible. Let's go.

First off, what's this mint authority thing anyway?

Mint authority is basically the VIP pass to create more of your token. When you make an SPL token on Solana, your wallet gets it by default. Cool for initial supply. Sketchy if you leave it. Anyone with that could flood the market. Revoking it sets it to null. Permanent. No take backs. That's the point - proves you're not gonna inflate and bail.

In my experience, I revoke right after liquidity's added. Holders love seeing that explorer update. "Mint authority: null." Boom, legitimacy. But the thing is, it's irreversible. Double check your token address or you're toast. Sound familiar? Happened to a buddy once. Wrong token, supply locked on a testnet dud. Laughed about it later.

Quick pros before we hit steps

Fixed supply. No dilution.
Builds trust. Dexscreener shows it clean.
Security bump. Can't get hacked to print more.
Decentralization flex. Community owns it now.

Tool showdown: Which one to use?

Okay, three solid no code spots. I rotate 'em. CoinFactory if I'm lazy, Solhub for speed, 20lab when I wanna check other auths too. Smithii's dead simple too. Pick based on vibe.

Tool	Best for	Fee	Extras
CoinFactory	Beginners	~0.005 SOL	Token creator check
Solhub	Fast revokes	~0.002 SOL	Wallet selector
20lab	Multi auth	~0.01 SOL	Transfer or revoke, freeze too
Smithii	Wallet token pick	Super cheap	No address hunt

Don't overthink. Any work. I usually hit Solhub first.

Doing it on Solhub - my go to quickie

Alright, hands on. Pretend you just launched via pump.fun or raydium. Token address in clipboard. Here's the play by play.

Hit up Solhub's revoke page. Top right, smack "Select Wallet." Phantom, Solflare, whatever you got. Connects in seconds.
Paste your token address. Exact mint address, not the site link. Copy from solscan or dexscreener.
Double eye it. Wrong one? Game over.
Click "Revoke Mint." Wallet pops. Fee ~0.002 SOL. Approve.
Wait 5 secs. Done. Check solscan - mint auth null.

That's it. Took me 45 seconds last time. But hey, what if it errors? "Insufficient funds?" Top up 0.1 SOL. "Not authority?" Wrong wallet, dummy. Use the one that created the token. Fixed that for a friend yesterday.

20lab way - if you wanna get fancy with all authorities

Sometimes mint ain't enough. Revoke freeze too, or transfer to a multisig. 20lab handles five types: mint, freeze, metadata, taxes. I dig it for projects.

Connect wallet. Enter token address. Dropdown screams "Mint authority." Current holder shows - gotta match your wallet or bounce. Hit revoke. Confirm. Same drill, verifies on explorer after.

Pro move: Transfer first to a safe wallet, then revoke from there. Extra layer. But honestly, direct revoke's fine for memes.

Trouble shooting this one

If it says "authority mismatch," you're not the holder. Check solscan.io/token/YOUR_TOKEN#authority. Find the wallet with mint auth. Switch to it. Boom.

CoinFactory run through, step for step

Similar vibe. Go to their revoke mint page. Connect creator wallet. Enter contract address. Confirm in wallet. They handle the tx. Clean UI, shows before/after.

I used this for my first token. Felt official. Fee was 0.005 SOL then, probably same now.

Potential snag: Site down? Rare, but switch tools. Solana congestion? Retry in a min, network's fast anyway.

Smithii - laziest option ever

Connect wallet.
Pick token from your list. No typing!
Revoke. Done.

Perfect if your authority wallet holds the token. Zero brain.

Okay, but what if you're a coder? CLI or script it

You asked for practical. Most don't code, but here's the dev path. Use spl token CLI. Install via npm or brew.

First, fund your keypair wallet. Then:

solana keygen recover
spl token authorize YOURTOKENMINT mint --disable

That's revoke. --disable sets null. Cost: 0.000005 SOL gas. Verify: spl token display YOURTOKENMINT.

Or JS with Metaplex. I scripted a batch for 50 SFTs once. Grab umi, mpl toolbox. Set authority to null.

Code snippet? Sure, but keep it simple. Don't wanna scare ya.

import { createUmi } from '@metaplex foundation/umi bundle defaults';
import { setAuthority } from '@metaplex foundation/mpl toolbox';
import { AuthorityType } from '@metaplex foundation/mpl toolbox'; const umi = createUmi('https://api.devnet.solana.com');
await setAuthority(umi, { authorityType: AuthorityType.MintTokens, newAuthority: null, // Revoke! owned: publicKey('YOUR_MINT'),
}).sendAndConfirm(umi);

Plug in mainnet RPC for prod. Test on devnet first. Errors? Wrong signer or RPC lag.

Common screw ups and fixes

Look, I've messed up. You might too. Here's the dirt.

Wrong token address. Paste error. Solscan it first. Ends in unique hash.

Not the authority wallet. Creator wallet only. Export private if needed, but hardware's safer.

Tx fails mid congestion. Solana spikes. Wait, or priority fee up 0.0001 SOL.

Already revoked? Tool says no op. Good, you're safe.

Post revoke transfers? Fine. Just can't mint more. Sell, swap, all good.

One more: Pump.fun auto revokes. Check yours. If null already, chill.

When to pull the trigger

Timing's. After LP burned, pre raydium list. For NFTs, post mint. Memecoins? Right after bonding curve done. Don't wait - FUD kills faster than rugs.

In my experience, announce it. "Mint revoked, supply fixed at 1B. Check solscan." Moonshots follow.

Bonus: Revoke freeze authority too?

Hell yeah. Freeze lets you lock accounts. Rug tool. Revoke same way. Tools have dropdown. Do both. Holders sleep better.

Multisig it first if team. But for solos, null 'em.

Aftermath - what changes?

Supply immutable. Explorer shows null. Dextools badges it "fixed supply." Value holds on dips. Community chants your name.

But can't expand supply later. Plan tokenomics right. 1B max? Stick it.

Go revoke yours now. Takes 2 mins. You'll thank me when the chart pumps.
