Launch

Launch a Token

POST /trade/local/launch

Create a local transaction to launch a token.

Body

Name	Type	Required	Description
mint	string	Yes	bs58 public key for the mint.
publicKey	string	Yes	bs58 public key of the dev wallet
amount	number	No, but if you want the dev wallet to buy you have to choose between amount or percentage; not both.	Amount to buy on the dev wallet denominated by ccy field.
ccy	"sol" | "lamports" | "token" | "usd"	Yes IF amount is provided; No IF using percentage or not buying on dev wallet.	Denomination for amount field (buy 1 sol, buy 1 usd, etc...)
percentage	number > 0 & <=100	No, but if you want the dev wallet to buy you have to choose between amount or percentage; not both.	Percentage of account to buy (1 =1%, 10=10%). Buying 10% means spending 10% of sol in your wallet. There is a known bug when buying super high percentages due to fees. We have acknowledged this issue and are actively working on a fix. We recommend not buying more than 80%.
priorityFee	number > 0.00001	No - defaults to 0.001	Priority Fee denominated in solana. The higher it is, the faster and higher success rate for the transaction is. You can get the optimal priority fee from Recommended Priority
tokenMetadata	object	Yes	An object containing the following fields.
tokenMetadata.name	string	Yes	The name of your token - must match one posted to pump.fun
tokenMetadata.symbol	string	Yes	The ticker of your token - must match one posted to pump.fun.
tokenMetadata.uri	string	Yes	The ipfs url received from posting metadata to pump.fun.

Response

201

Serialized V0 Transaction as bytes.
