Mint authority is the wallet allowed to call the SPL Token Program's `MintTo` instruction and create new supply. For memecoins, revoking mint authority (setting it to `null`) is the single most important trust signal — it locks the total supply mathematically so no future inflation is possible. The articles below cover how the authority works on-chain, why traders reject tokens with active mint authority, how to revoke it correctly, the legitimate cases for keeping it active (utility tokens with planned emissions, stablecoins) and the multisig delegation pattern (Squads, Realms) that splits the difference between fully revoked and single-key control.

How these Mint Authority guides connect
Every guide tagged mint-authority is written from the operator's seat — by people who have launched real Solana tokens and watched what actually happens after the transaction confirms. Rather than abstract documentation, each piece covers the on-chain mechanics, the irreversible decisions, and the verification steps you check on Solscan, DexScreener, and Phantom before and after you sign. Read them together and you get the full picture for this part of the launch, not an isolated how-to.

When you're ready to ship, the Solana token creator handles the mint, metadata, and authority revocation in one no-code flow — no Rust, no CLI.
