Simple Summary

Redirect 20% of daily emissions from the USDs - SPA farm to a new APR USDs - USDC farm.

Abstract

To ensure adequate liquidity for peg stability, the Sperax team is proposing to launch a new incentive for users to park liquidity into the USDs - USDC Uniswap pair on Arbitrum. Instead of adding to the daily emissions, we propose to redirect emissions from the existing USDs - SPA pool to this new one.

Motivation

To ensure USDs keep it’s peg, there must be adequate liquidity on DEX’s to ensure arbitrage is profitable. We could launch a new farm which would require additional SPA emissions, and potentially SPA sell pressure, or we could redirect from the existing USDs - SPA farm. We propose to redirect instead of adding to emissions.

Overview

Currently the Reward Rate for the SPA-USDs farm is

1. For all users (lockup+no lockup) = 466.663K SPA/Week
2. Additional reward rate for lockup users = 233.331K SPA/Week

20% of this pool will be redirected to the new farm to incentivize USDs - USDC liquidity.

So reward rate for the new USDC-USDs farm will be

1. For all users (lockup+no lockup) = 0.2 * 466.663K SPA/Week
2. Additional reward rate for lockup users = 0.2* 233.331K SPA/Week

New reward rate for the existing SPA-USDs farm will be

1. For all users (lockup+no lockup) = 0.8 * 466.663K SPA/Week
2. Additional reward rate for lockup users = 0.8* 233.331K SPA/Week

Technical Specification

Sperax team will use the Multisig to redirect rewards from the USDs - SPA pool to the USDs - USDC pool. To fund this pool 20% of the daily emissions will be redirected from the existing pool to the new pool. There will be 93,332 SPA/Week going to all users and an additional 46,662 going to lockup users as a bonus. This number was calculated by taking the weekly reward of the current farm for all users 466,663 *0.2 and the weekly lockup bonus of 233,331 *0.2.
