Stem is a Helius-powered launchpad where every coin is paired to a parent: any meme on Solana, $STEM, or a coin already in the family. $STEM launches on pump.fun. Every coin under it trades on a Meteora curve priced in its parent.
Pairing is how KOLs pump main coins now: launch a side coin paired to the main coin, and every buy of the side coin has to buy the main coin first. It works, but every pair is a one-off that gets dumped.
Stem makes the pair permanent. $STEM is generation 0. Every coin launched here is its kid, or a kid of a kid. Every win anywhere in the family pushes the same chart up.
A coin's curve trades against its parent, not SOL. Buy it with SOL and the swap routes down its whole line in one transaction: SOL to the top of the line ($STEM or the meme it was paired to), then down to your coin.
Any Solana meme with at least $100K market cap and real liquidity can be a parent. Pair a coin to WIF and every buy of it buys WIF first.
Selling runs the other way, back up to SOL. You never have to hold the parents yourself.
Every trade pays 1%, in the parent. Meteora keeps 20% as its protocol fee. 45% goes to the vault, which swaps it to SOL and pays $STEM holders every 10 minutes. 20% goes to whoever launched the coin. Both are paid privately through Helius Privacy Rings. 15% is lift: it buys the coin closest to bonding and burns what it bought, so the family keeps graduating.
Coins paired to an outside meme have no lift: the vault's share of their fees, 60% of every fee, goes to $STEM holders, and 20% to the launcher, both privately.
Paying launchers is the difference. A KOL who launches here earns from their coin for as long as it trades, so they keep it alive, and every buy it gets still buys $STEM.
No dev buy, no allocation, no presale. Launching is one transaction, about 0.03 SOL in rent. A ticker, name or picture that is already in the family is refused, so nobody can clone a coin that's working.
A coin's curve raises a fixed amount of its parent, set at launch: half the parent's market cap, between $3K and $10K, and never more than would double the parent. Small curves actually fill.
When a coin bonds it moves into a Meteora pool against its parent, and the liquidity is locked forever.
Every launcher and holder payout goes through Helius Privacy Rings, live on Solana mainnet. The chain sees Stem pay a wallet, but the amount is encrypted. Nobody can see what a KOL made from a coin, or what a holder was paid.
To receive privately, open a Privacy Rings wallet. Wallets without one are paid in plain SOL. Stem is independent and not affiliated with Helius.
