Supply Referral

The supply referral system allows users to earn a portion of the protocol fees generated by liquidity suppliers they refer. When a supplier deposits assets using your referral ID, you earn fees proportional to interest paid over time.

How it works

1. Create a referral: Mint a SupplyReferral object for a specific margin pool
2. Referral ID: Suppliers include your referral ID when supplying liquidity
3. Earn fees: As referred suppliers earn interest, a portion of protocol fees accrues to your referral
4. Claim fees: Withdraw accumulated referral fees at any time

The referral system uses a shares-based tracking mechanism. When a supplier deposits with your referral:

• Your referral's shares increase proportionally to the supplier's position
• As interest accrues and protocol fees are collected, your claimable fees grow
• When a supplier withdraws, your referral's shares decrease accordingly

Fee distribution

The referral spread parameter (typically 20%) determines what portion of protocol fees goes to referrers. For example:

• Without referral: 100% of protocol fees go to the protocol
• With referral: 80% to protocol, 20% to referrer (at 20% referral spread)

The referral spread is configured per margin pool and can be viewed in the Contract Information.
