Cross-chain Farming V2

What Symbiosis cross-chain farming is and how to get rewards with the Cross-chain farming program for providing liquidity.

Cross-chain Farming V2 Intro

Check available Symbiosis reward programs: Symbiosis Reward Programs​
Symbiosis protocol V2 owns an AMM multi-stablecoin liquidity pool to implement cross-chain operations.
Once you supply liquidity to this liquidity pool, you get rewards* from Symbiosis every week as long as your liquidity stays in the pool.
If your liquidity stays in the Symbiosis liquidity pool and you have joined the veSIS reward program as well, you get Boosted APR instead of Base APR.
When you withdraw your liquidity, you get your assets back and your share of the liquidity provider fees.
The liquidity provider fees are charged for all swaps performed on the AMM pool. The fees taken during trades are added to the total liquidity of the pool. When a liquidity provider withdraws their assets from the pool, they also receive a proportional share of all fees collected since the liquidity was first added. This mechanism is a part of the AMM pool protocol. The main points here:
  • You get rewards once: when you withdraw liquidity,
  • The rewards are in the tokens of the pool,
  • The reward amount depends on the trading activity in the pool and is hard to predict.
Symbiosis provides a cross-chain farming program to reward its liquidity providers additionally. The main points of the program:
  • You get rewards every week as long as your liquidity stays in the pool,
  • The rewards are in SIS tokens, the Symbiosis protocol token. For more information about the token (rates, Tokenomics, etc.), please refer to SIS Token.
  • The reward amount is predictable,
  • Liquidity providers can withdraw assets at any time,
  • There is a vesting period for a part of the rewards (see Vesting Period).
Cross-chain farming V2 is a part of Symbiosis protocol V2. The service:
  1. 1.
    Recalculates APRs of the Symbiosis liquidity pool,
  2. 2.
    Monitors adding/withdrawing liquidity to/from the Symbiosis liquidity pool,
  3. 3.
    Calculates and accrues rewards to liquidity providers (once a week),
  4. 4.
    Tracks reward withdrawal.

Base and Boosted APRs

APRs of the Symbiosis V2 liquidity pool are calculated and charged in SIS tokens.
To check the current APRs values, navigate to Symbiosis WebApp > the Pools tab:
​
For every stablecoin in this pool, there are two APR values:
  • Base APR shows the estimated annual rate for providing liquidity.
  • Boosted APR shows the estimated annual rate for liquidity providers who have veSIS tokens. The threshold for Boosted APR is 2,500 veSIS tokens. For more information on veSIS refer to this guide: veSIS reward program.

Vesting Period

Rewards are calculated and accrued once a week and added to the personal rewards balances of liquidity providers. Part of the rewards becomes available for claiming immediately; another part is held aside, becomes available for claiming partly, and can be claimed in full as soon as the vesting period ends.
  • The vesting period is 26 weeks (roughly half a year).
  • The part of rewards that becomes available for claiming straight away is 30%.
  • The vesting rewards (the part of rewards held aside becomes available for claiming partly and can be claimed in full once the vesting period ends) is 70%.
Let's consider an example. A user added 10 tokens to a liquidity pool, kept them there for one week and withdrew the tokens. Let's assume that the reward for one week of providing this amount of tokens in this pool is 1 SIS. Let's consider that the user doesn't claim rewards partly when they become available for claiming. Then
  • 1st week: 0.3 SIS is available for claiming, and 0.7 SIS is held aside,
  • 2nd week: (0.3 + 0.7/26) SIS is available for claiming, and (0.7 - 0.7/26) SIS is held aside,
  • 3d week: (0.3 + (0.7/26) * 2) SIS is available for claiming, and (0.7 - (0.7/26) * 2) SIS is held aside,
  • ......
  • 26th week: (0.3 + (0.7/26) * 26) SIS is available for claiming, and (0.7 - (0.7/26) * 26) SIS is held aside -> 1 SIS is available for claiming, and 0 SIS is held aside.
Symbiosis does not charge compound interest on rewards that are not claimed.
