How Keystone works

Pick a name, a ticker, an image, a supply and a starting market cap. Choose what your token trades against, choose a mode, and launch. One transaction on Arc creates the token, opens its market and locks the liquidity.

Gas on Arc is paid in USDC, and so is everything you buy here. Your first buy, if you make one inside the launch transaction, is paid in USDC too.

No wallet yet? Sign in with X and one is created for you. You can take its key whenever you want, from the Rewards page.

The whole supply goes into a single-sided Uniswap v4 position that only the locker can add to. Nobody, including us, can pull it out.

The mode you pick at launch decides how the fee behaves and where it goes. It is fixed for the life of the token. Every trade pays the fee in the paired asset, buys and sells alike. 30% runs the platform, and the rest follows your mode.

On a Protected Launch, only buys fade. Sells pay your resting fee from the first second, and your own first buy, made inside the launch transaction, is exempt. The point is to make racing the launch worthless, not to tax you.

A pair asset is what people trade your token against. USDC is the default, and it is also what every buy is paid in. There are three kinds to pick from.

EURC gives your token a euro market. The Arc tokens are communities that already trade against USDC.

The tokenized stocks (CRCL, NVDA, SPCX, SPY, GME, AAPL and TSLA) are issued on Arc by a single issuer. That issuer can mint more of them and pause their transfers. A paused pair asset freezes trading in every token paired with it, and the fees paid in it. Keystone shows this next to each one, wherever you pick it or see it.

Some stocks are thin. They pair fine, but without a one-click buy in USDC: you trade them with the stock itself, and the picker says so.

Anything else can be submitted from the launch page or the listing page. It is listed if it is a normal ERC-20, takes no tax on transfer, and has at least $10,000 of real liquidity against USDC.

Other pair assets can have an owner who can pause transfers, mint more, take a fee or cap how much one wallet holds. When a pair can do any of that, the pair picker says so next to it, before you choose it.

Your share of the fee can go to three recipients instead of one. Each slot is a wallet or an X account, with a percentage you set at launch. The percentages never change afterwards.

An X account does not need a wallet. The fees accrue to an address derived from the handle, which nobody holds the key to. When the owner signs in with X on this site, the handle is bound to their wallet, once, and everything waiting is paid out. We cover the gas.

Each recipient can hand their own slot to another address later. Nobody can touch anybody else's slot, and nothing already earned ever moves.

Claim your fees from the Rewards page, in the asset your token trades against.

On a Community Launch, the holder share is paid out automatically, pro rata, to everyone holding the token. There is nothing to stake and no button to press. On a USDC pair, holders are paid in USDC.

A payout waits until the pot is worth more than the gas it costs to send, so a quiet token pays less often rather than burning its holders' rewards on fees.

Every launched token can get its own website. Open the token page, choose Build AI site and describe the style and story you want. The AI writes the page, picks an art direction and keeps the market numbers live.

You can ask for changes, adjust the theme and colors, preview mobile and desktop, then publish with one wallet signature. The signature proves the token creator approved the site. It sends no transaction and costs no gas.

Launched tokens are plain ERC-20s. No owner, no mint function, no pause, no blacklist, no tax on transfer. The supply that exists at launch is the supply forever, and every Keystone token address ends in 222.

The fee is set once and can never be raised. The liquidity belongs to the locker and cannot be removed. Fees already credited to you cannot be moved by anyone.
