What this is. This site shows coins that a contract on the Base chain mints, backs and draws. The site reads the chain and nothing else. It holds no keys, no funds and no account of yours.

What you sign, you send. A mint goes from your wallet to the contract. You send the backing, 5, 10, 25 or 50 USDC a coin, and USDC needs one approval the first time. You send a Chainlink fee in ETH with the transaction, and the contract passes it to Chainlink for the randomness. You pay the network gas. A transaction that fails still costs gas. Every fee the contract takes is written on this site before you sign.

The contract is the product. The contract puts your USDC into a third-party vault on Base that follows the ERC-4626 standard and keeps the shares under your coin. Burn the coin 30 days after its mint and the contract sends back the backing plus the yield it earned, minus 10% of that yield. The art comes from a Chainlink VRF seed and a slot drawn from the urn, so nobody picks it, and 50 slots of the 25,000 in a series are Master Coins. 100 founder coins a series go to the author, minted inside the first 1,000 coins of that series or forfeited, and the contract funds them from the author's share of the yield. The image is not frozen: the ring outside a coin grows with the yield that coin has earned and never shrinks. The contract has no pause on redeem and no key that can move the funds. Read how it works before you mint.

No promise of value. This is not an investment and never will be. ONE can lose you money. The backing sits in a third-party lending vault on Base; if that vault is hacked, drained or frozen, the coins hold nothing and nobody makes it up. Yield can be zero. The coins may never trade; there may be no buyers at any price. Nobody promises a return, and the odds that this earns you nothing are large. Put in only what you can lose. Nothing on this site is financial, legal or tax advice. Your taxes and the law where you live are yours to follow.

No warranty. The site can go offline, show stale data or have bugs. The coins do not depend on it: the image and the money live in the contract. The site and the code come as they are, with no warranty of any kind.

Licence. Images and code are CC0. Use them for anything, with or without credit.
