Introduction

Flume is a market for creator fees on Solana. A token creator sells a share of the fees their token will bring in over the next days or weeks, and a vault funded by liquidity providers pays for it in USDC, up front. The vault then takes its share of every fee that arrives until the term ends or it has collected its cap.

The short version

• You pick the terms. Sell up to 50% of your fees, for one to thirty days.
• The price comes from your own history. Flume runs the last seven days of fees across the term you pick and pays a quarter of your share of it.
• The vault's share is capped. It stops at twice the price or at the end of the term, whichever comes first. After that, every fee is yours again.
• There is no recourse. If fees fall short, the vault takes the loss. You never owe anything back.
• Every payment splits on chain. The vault's share goes straight to the vault; yours waits in your source until you claim it.

Who it's for

Creators who earn fees from a token and would rather have cash now than wait for it to trickle in. Selling a share of future fees is an alternative to selling the token itself.

Liquidity providers who want exposure to many creators' fee streams at once. LPs deposit USDC into a single vault, and the vault spreads it across streams under fixed limits.

What you need

• A Solana browser wallet that supports the Wallet Standard, such as Phantom, Solflare or Backpack. Flume asks it to sign transactions, and to sign one message when you request a quote.
• For creators: the mint authority of your token, and a little SOL for transaction fees.
• For liquidity providers: USDC, and a little SOL for transaction fees.
