Fee System

Streamflow charges small protocol fees on stream operations. Fees are taken in the streamed token (or SOL for native SOL streams). Lock streams and vesting streams have separate fee tiers - the SDK classifies your stream automatically, so there's nothing extra to configure.

Current fee rates are shown in the Streamflow app as a fee breakdown on the review step before confirming any transaction.

Referral partner

Each creation function accepts an optional partner field. When provided, the on-chain partner program applies the fee schedule negotiated for that address rather than the default rates.

await createLock(
  {
    recipient,
    tokenId,
    amount,
    unlockDate,
    name: "Team Lock",
    partner: "PartnerPublicKeyHere", // optional
  },
  invoker,
  env,
);

The partner field is available on createVesting, createLockBatch, and createVestingBatch as well.
