# Referral codes Send traders to buy through pumpdata and get 30% of our fee on every trade they make with your code, paid to your wallet inside the trade itself. Nothing to claim, nothing held. - Our fee is 0.4% of the SOL side of a buy or sell ([/buy](https://pumpdata.fun/buy)). With your code, 30% of it (0.12% of the trade) is a second transfer in the same transaction, to your wallet. The trader pays the same 0.4% either way. - Your link: `https://pumpdata.fun/buy/?ref=yourcode`. The buy page remembers the code for 30 days. Agents and bots pass `"ref": "yourcode"` in `POST /buy` or `/sell`. - In a Telegram group with our bot, an admin sends `/ref yourcode` and the group's buy buttons carry it. - Your wallet must hold Solana's rent minimum (0.00089 SOL) before a share can land in it. A trade with your own code from your own wallet pays no share. First come, first served; a code cannot be moved to another wallet by itself (write to support@pumpdata.fun).
