Concepts

$PLINTH

Plinth's own token, its fixed supply and public launch, and the 1% of every sale that buys it to burn.

$PLINTH is Plinth's own token. It is separate from the tokens launched with Plinth: each of those belongs to the project that launched it, with its own mint, treasury and floor.

Supply and launch

Ticker	$PLINTH
Supply	1,000,000,000, fixed
Launch	100% of the supply in one public launch, on the same terms for everyone
Held back	none: no presale, team allocation, investor allocation, airdrop, reserved supply or vesting

Every purchase in a Plinth sale pays 1% of its cost to the protocol. The program takes it first, then the team share from what is left, and the rest goes into the launch's treasury, all in the purchase's own transaction.

Each purchase pays the protocol its 1% first, then the team its share of the rest, and the treasury keeps what is left. The protocol share buys $PLINTH to burn. Example at $1.00 a token with a 20% team share, one tooth per cent.

For a purchase that costs C in a launch with a team share s:

Part	Amount	Goes to
Protocol share	C × 1%, rounded down	the protocol's USDC account
Team share	(C − protocol share) × s, rounded down	the launch's team wallet
Treasury	the rest	the launch's treasury vault

Which sales pay it

A launch's first sale.
Every follow-on sale. A follow-on sale sells through the same purchase instruction as the first one, so each of its purchases splits the same way. Its lowest start price allows for both shares, F ÷ (0.99 × (1 − s)), as Follow-on sales explains.

Nothing else pays it. Yield goes to the treasury and the team as the launch's yield route sets, and redemption fees stay in each launch's own treasury.

Buy and burn

All of the protocol share buys $PLINTH in the market, and every $PLINTH it buys is burned. Burned tokens leave the supply for good.

The protocol share collects in one USDC account owned by the protocol's program address, seed "protocol". No wallet holds its keys, and the program moves money out of it only to buy $PLINTH to burn.

Where you see it

Studio: Launch a token shows To the protocol beside the team's amount and the treasury.
Token pages: the launch terms list the Protocol share at sale, and each purchase quote shows the Protocol share in USDC.
Receipts: a purchase's receipt and its event record the protocol share as fee_atoms. See Program.
