Subscription

Colend subscriptions give you access to boosted yields on the assets you’ve supplied, through a monthly payment in CLND. Rewards are paid in the same asset you supply, no extra tokens, no complex mechanics. Just more earnings.

The simple idea

A Subscription is a time-limited access pass that lets your deposit earn an extra yield on top of the pool’s normal yield. You spend a small amount of CLND for the period, and while the Subscription is active your eligible liquidity receives the bonus. There is no waiting for distant promises or complicated token games; you decide whether the added yield is worth the CLND you spend, and you can even enable auto-renew so you don’t accidentally lose access. A profitability simulator on the app helps you check the numbers before you subscribe.

Economic Rationale

Colend is the first protocol introducing a (MRR) dynamic into DeFi. Users periodically spend CLND for clearly defined access, which creates steady, predictable inflows linked to a concrete service. This has two audiences in mind. Depositors receive a defined benefit while their subscription is active. CLND holders see recurring, usage-driven demand for the token instead of vague dividend-like expectations.

A second and equally important consequence is what happens to the CLND that users spend. Those tokens are not simply pushed back into circulation. They are retained by the protocol to strengthen protective buffers against potential shortfalls and to improve scarcity. In practical terms, this creates a reserve that can help the protocol absorb stress during exceptional market events, including black swan scenarios.

Revenue Sharing

When borrowers repay, fees are shared with depositors and the protocol’s reserve. The Subscription module redirects a portion of those fees into a rewards vault that is only available to active subscribers of a given pool. Subscribing spends CLND and mints a non-transferable SBT (Soulbound Token) that serves as your access pass and tracker. While the SBT is valid and you have liquidity in the selected pool, the system recognizes that you are entitled to the subscriber-only rewards.

To keep the system fair and avoid dilution, governance can limit how much of each user’s deposit is eligible for the bonus and can also limit the number of active subscriptions if needed. The module has been audited by Verichains.

Parameters

Each subscription is for one asset only. If you subscribe for USDT, the bonus applies to your USDT deposit. It does not apply to any other asset. Think of each asset as having its own “pass.”

When you subscribe, rewards build up over 30 days. During those 30 days you can claim them at any time. If you forget to claim before the 30 days end, do not worry: your earned rewards are not lost. They remain available for you to claim later. The 30-day window limits how long new rewards are earned, not whether you can retrieve what you already earned.

Each subscription has its own price in CLND. You pay this price to activate the 30-day access for that asset. Your decision is simply whether the expected extra yield for the next 30 days is worth that CLND spend.

Each subscription also has three key parameters that shape how much you can earn: - the reward speed is the pace at which rewards are released during the 30 days - the budget is the total amount set aside for that subscription period. - the Sub cap is simply the maximum part of your deposit that can receive the bonus during the 30-day period. If your deposit is at or below the cap, all of it is eligible for the bonus. If your deposit is above the cap, only the amount up to the cap earns the bonus; the rest still earns the pool’s normal (native) yield.

Together, they define the reward “curve” for the month. If more people subscribe and add liquidity, the same budget is shared among more deposits, so the effective APR can go down; if fewer people subscribe, it can go up. This is normal and part of how the system stays balanced.

Computation Method

Only the portion of your deposit up to a per-subscriber cap is eligible for the bonus. Anything above the cap still earns the pool’s native yield, just without the bonus.

R : Estimated annual reward D : your deposit C : the max cap per subscriber 𝑦 native : the native APY 𝑦 bonus : the bonus APY available to subscribers. 𝑦 eff: Blended APY across the entire deposit.

$$R = \min(D, C)\cdot (y_{\text{native}} + y_{\text{bonus}});+;\max(D - C, 0)\cdot y_{\text{native}}$$

$$y_{\text{eff}} = \frac{R}{D}$$

Example

Assume a cap of 200,000 USDT per subscriber. Assume a 25% native yield and a 5% bonus yield. If Alice subscribes and supplies 250,000 USDT.

_{𝑦 native = 25% 𝑦 bonus = 5% C = 200,000 USDT D = 250,000 USDT}

$$R=200,000×0.30+50,000×0.25=72,500 USDT$$

$$yeff​=DR​=\frac{250,000}{72,500}​=0.29=29$$

👉 Alice receives a blended APY of 29 percent instead of 25% without subscription.

If you feel ready, you can open the Subscribe page, try the simulator with your own deposit size, and decide whether a Subscription suits you. If you prefer to move slowly, you can read the step-by-step tutorial before taking action.
