SIP-108: Shorting Rewards
Incentivise users to open shorts against sBTC and sETH.
Users who open shorts will be automatically enrolled into an SNX rewards program.
Initially, the trial will run for a period of 4 weeks. The sDAO will pay 8k SNX per week to sBTC shorts and 8k SNX per week to sETH shorts (16k SNX total per week). Tokens will be distributed on a pro rata basis.
If the user's position is modified (increased, decreased, liquidated or closed), their rewards balance will be updated for them by the contract.
The debt pool is still heavily skewed toward sBTC and sETH, despite active rewards programs for holding iBTC and iETH. In the context of a bull market, this skew represents a significant risk to SNX stakers.
The design of Shorting Rewards is structurally identical to that of the current Staking Rewards contracts. The only difference is that instead of staking tokens, positions are created automatically when users open shorts.
The Synthetix Staking Rewards contract has become widely used across DEFI. The underlying structure is well understood by the community.
A new contract
ShortingRewards.sol which is a modified version of
StakingRewards.sol. It shares the same underlying logic for determining reward amounts. Where it differs is that there is no staking token. Instead, it stores a reference to
CollateralShort.sol and allows this contract to enrol and withdraw users.
Two instances of
ShortingRewards.sol will be deployed. The first instance will manage rewards for sBTC shorts and the second will manage rewards for sETH shorts.
Test cases are included with the implementation.
Configurable Values (Via SCCP)
For both instances of
ShortingRewards.sol, the following variables are configurable.
rewardthe amount of SNX paid out by the contract.
rewardsDurationthe duration over which the reward is paid out.
Proposed Initial Values
The following values are proposed as the initial configuration.
