Quickstart

Five minutes, in the browser. Then the same thing from the command line.

On this site

1. Open Launch and connect a wallet (any wallet that supports Robinhood Chain; if the network is missing, the site asks your wallet to add it). Give the coin a name and a ticker.
2. Pick a pair, or paste any token address on Robinhood Chain and press Check. If the token has a pool, its dollar price loads; otherwise you get the numbers in token units.
3. Set the opening market cap. The panel shows what buyers will pay to fill the curve, what goes into the pool, and where the coin graduates.
4. Optionally set a first buy. Press Review launch, check every transaction, then Sign and create. Your wallet confirms each step in turn and the site takes you to the new coin.
5. On the coin page, buy and sell with the ticket. When the curve fills, the pool opens in the same transaction.

From a terminal

You need the Yoke address (shown on Contracts once deployed) and Foundry's cast. USDG appears below only as an example: use the address of whichever pair you choose.

# 1. approve the pair token for the optional first buy
cast send $USDG "approve(address,uint256)" $YOKE 500000000 --rpc-url $RPC --private-key $KEY

# 2. create the coin: opens at 5,000 USDG, first buy of 500 USDG
cast send $YOKE "create(string,string,address,uint256,uint256,uint256)" \
  "Moonlit Cat" MCAT $USDG 5000000000 500000000 0 --rpc-url $RPC --private-key $KEY

# 3. read the curve
cast call $YOKE "curves(address)" $TOKEN --rpc-url $RPC

For a WETH pair the opening cap is in wei and you buy with ETH directly:

cast send $YOKE "create(string,string,address,uint256,uint256,uint256)" \
  "Pocket Sun" SUN $WETH 2000000000000000000 0 0 --rpc-url $RPC --private-key $KEY
cast send $YOKE "buyETH(address,uint256,address)" $TOKEN 0 $ME --value 0.5ether --rpc-url $RPC --private-key $KEY
