Create a pump coin. Set its fee split.
Two wallet approvals. The first creates the coin; the second sets the split for good. Your key stays in your wallet.
About 0.02 SOL in rent, plus two network fees. Buying at launch is optional. Already have a coin? Enroll it at /enroll.
Describe the coin
Metadata URI:
Set the split
pump pays a share of every trade to the coin’s creator vault. This split decides where that share goes, and it is set once.
The protocol row
Fixed at 0.25% of each transaction. It buys and burns $CHARLIE, and it is what makes this coin part of Charlie Protocol. You cannot edit it.
Your rows
Share the rest and must total 100%. The incinerator row is fixed: SOL sent to it is destroyed, and you choose how much, from 1% up. Every other row is a wallet that receives SOL.
The buyback row
Every coin made here includes the shared buyback treasury. The address is fixed and the row cannot be removed; you choose its share, above 0%.
How it pays out
pump holds the creator fees in the coin’s vault and pays the rows when its minimum is met. A keeper asks for the payout; anyone can. No signature needed.
Connect
Your wallet is the creator and fills the wallet row above. Connecting signs nothing.

Check and sign
The buy lands in approval 1, before the split is set: its creator fee goes where pump sends it by default.
The coin’s address (CA):
Ends in 1nc1n: the mark of a coin made here. The mark is not proof; the split on chain is.
pump allows one fee split change, and approval 2 is it. After it confirms, no key can change the split, including yours. Trades that land between the two approvals pay pump’s default.
- 1. Create the coin
- Wait for confirmation
- 2. Set the split
Split confirmed on chain. pump pays the rows from the creator vault when its minimum is met; a keeper requests the payout. If your split has an incinerator row, its first payout is the first SOL burn.
How it works on chain
Transaction 1: create
pump’s own create instruction, your wallet as creator, co-signed by a mint key the server made ahead of time. That key signs once and holds nothing after. Trades before transaction 2 pay pump’s default.
Transaction 2: split
create_fee_sharing_config, then update_fee_shares_v2 with admin_revoked. Payouts come from the creator vault; anyone can request one, no signer needed.
If transaction 2 fails
The coin exists. Keep its address and set the split later at /enroll.
Evidence
The coin’s page reads the split and payouts from the chain. Creating a coin here publishes no listing on its own.
