Author:

@Tshaw from Sperax / $USDs

Summary

Deploy arbUSDv3 pool consisting of $USDs, $USDC and $USDT, redirect $SPA and $SDL incentives from $USDs-arbUSDV2Metapool to arbUSDv3 pool. Only applies to Arbitrum network.

Abstract

$USDs metapool has grown to be the largest Arbitrum pool, surpassing all primary pools but at least 2x. The pool now holds over $28M of stablecoin liquidity.

Specification

• Launch new pool consisting of $USDs, $USDC, $USDT
• Redirect the remainder of the SDL and SPA rewards from $USDs-metapool to primary pool

Motivation

• Sperax has removed significant risk: proved ability to attract liquidity to the pool and maintain $USDs peg stability
• Half of the Metapool pool is contributing to the peg stability and liquidity to competitors like FRAX.
• Largest stablecoin pool on Arbitrum should be a primary pool not a metapool.

For:

Redirect the remaining $SDL and $SPA from $USDs Metapool to arbUSDv3 pool.

Against:

Keep $SDL and $SPA distribution on the $USDs Metapool.
