Every Goldpad coin lives on Robinhood Chain, where real gold already trades. One percent of every trade on your coin is a fee, and eighty percent of that buys GLD and holds it for the coin. Hand your coins back whenever you like and take your share of the gold.
A name, a symbol, a few words, an image. The pad mints one billion coins and opens a curve for them. ETH sent with the launch buys the coin for you in the same block, so nobody is in before the creator.
Buys and sells run against one constant product forever. There is no graduation, no migration and no moment the market moves somewhere else. One percent of every trade is the fee.
The gold share of each fee waits as ETH under the coin. Feeding turns it into gold: ETH to USDG to GLD, on Uniswap v4, in one call anyone can make. The contract reads both pools' spot prices first and refuses anything under 97% of them.
Hand coins back and take their share of the gold. The coins are destroyed, so everyone left holds a little more gold per coin than before. Fees only add, redemptions burn exactly pro rata, and the floor never falls.
The gold is tokenized SPDR Gold Shares, the same Robinhood token that trades on the chain today. One share tracks about a tenth of an ounce of bullion held in a vault in London.
Every feed is a real swap on the gold pool, at the price it is trading at, checked against the pool's own storage in the same transaction. No oracle, no price feed, nothing to be fed a wrong number.
Gold sits under the coin it was bought for, and the only way out is a redemption by a holder. No address, ours included, can move a coin's gold, a curve's ETH or a creator's earnings.
Eighty percent waits under the coin until it is fed into gold. Fifteen percent goes to whoever launched the coin, claimable any time. Five percent is the protocol's. All three are written into the contract and none of them can be changed.
Anyone, and nothing beyond gas. Feeding is a public function. The caller can pass their own minimum, and on top of that the contract computes what the two pools' spot prices say the ETH is worth and refuses anything under 97% of it. A feed of a few dollars is not worth shoving a pool around for.
The gold pool is the thinnest link. Measured on a fork of the chain, a single feed of about 1.3 ETH still lands inside 97% of spot and 2.5 ETH is refused. So a feed can take part of what is waiting, and a coin with a lot of ETH under it is fed in a few calls rather than stuck.
Gold per coin is the gold held divided by the coins that exist. Fees only ever add gold. A redemption pays exactly the pro rata share and destroys exactly the coins handed back, which leaves the ratio where it was. The unsold coins on the curve count in the denominator, so a coin bought off the curve already carries its share. The property is fuzzed in the test suite.
One thing: which gold pool feeds route through, because the deepest pool is a fact about today. The gold token itself is fixed at deploy. Nobody can pause a curve, mint a coin, move gold, take a creator's earnings or upgrade the contract.
GLD on this chain is a tokenized fund, not bullion in your hand. Its implementation carries pause, block-address and admin-burn functions, and a coin whose backing is GLD inherits all of that. It is worth knowing before you hold a coin for the gold under it.
Because the gold is the point. A migration would move trading to a pool the fee no longer reaches. Here every trade, for as long as the coin exists, adds gold under it. The 0.05 ETH virtual reserve is never withdrawable, which keeps every seller payable down to the last coin.
