x405 hybrid token NFT explained: you don’t buy the NFT, your coin balance is the NFT
- One contract, two assets: 1 NFT = 1,000,000 tokens. Holding the coin means you already hold the NFT — no mint step.
- On the bonding curve, you pay only the 1% pool fee. Creator tax and ETH dividends switch on after the 4 ETH graduation.
- A 10% creator tax on Uniswap becomes 11% total with the 1% pool fee. Check the tax preset, split, and minimum holding threshold before buying.
I sent a small bag into a Robinhood Chain memecoin, watched it climb the bonding curve, and then my wallet showed an NFT I never minted. No second transaction, no extra mint button — the coin balance itself had become the collectible.
That’s x405 in practice. One contract carries both an ERC-20 with 6 decimals and an ERC-1155 NFT, locked at a fixed 1 NFT = 1,000,000 tokens. Traders ask which one to buy. Wrong question. You buy the token, and the NFT moves with it.
I’m talking about BigPump because it’s the launchpad that deploys these as Tax NFTs on Robinhood Chain (chainId 4663, gas paid in ETH). But the mechanic matters even if you’re just aping, not creating.
You don’t mint the NFT. Your balance is the NFT.
On a normal NFT drop, you sign a mint transaction and wait for metadata to land in your wallet. x405 flips that. The contract is always watching your token balance. Cross the 1,000,000-token threshold and the ERC-1155 appears. Sell below it and the NFT leaves. There is no separate mint button, no gas for a mint, no hidden step.
You don’t buy the NFT. You buy the token, and the NFT follows your balance.
That binding is what makes the pre- and post-graduation mechanics different.
Before graduation: only the 1% pool fee
While the token is on the bonding curve, you pay one thing on swaps: the 1% pool fee. No creator tax, no ETH dividends yet. This is the accumulation phase — volume pushes the curve toward the 4 ETH graduation mark.
After graduation: creator tax and dividends switch on
When the curve crosses 4 ETH, liquidity migrates and trading moves to Uniswap. Now the creator tax activates and ETH dividends start flowing. A launch with a 10% creator tax becomes an 11% total cost on Uniswap once you add the 1% pool fee. That’s why you check the token’s tax preset before buying — not after.
Two more dials matter. The split decides how fees divide among creator, liquidity, and holders. The minimum holding threshold decides whether your token balance counts as the NFT or just a dust position. Both vary by launch.
Your pre-buy checklist
- Hold 1,000,000 tokens = hold the NFT. No mint step.
- On the bonding curve, you pay only the 1% pool fee.
- After the 4 ETH graduation, creator tax activates. A 10% creator tax is 11% total on Uniswap.
- Check the tax preset, split, and minimum holding threshold before you buy.
That’s the entire x405 edge: one contract, two assets, and the NFT is just a function of your token balance. No extra gas, no extra transaction, no extra step.
