SCCP-251: Update Atomic Exchange Parameters - 1inch Integration

Simple Summary

Lower the atomic exchange fee on trades into sETH, with respect to the 1inch integration addresses specified in SIP-288, to 15 bp from 20 bp. Increase the atomicMaxVolumePerBlock to 5m sUSD from 3m sUSD on sETH and sUSD.

Abstract

The parameters being changed are as follows:

• The atomicExchangeFee is the fee applied on trades into a certain synth.
• The atomicMaxVolumePerBlock check is done on the source currency key.

Below are the DirectIntegration parameters of the 1inch addresses, specified in SIP-288:

{'currencyKey': 'sETH',
 'dexPriceAggregator': '0x9645C7de2DBe8AAda01868cAa393cB7e5253268c' (uses 30 bp uni pool),
 'atomicMaxVolumePerBlock': 5m$,
 'atomicVolatilityUpdateThreshold': 10,
 'atomicExchangeFeeRate': 15 bp}

{'currencyKey': 'sUSD',
 'dexPriceAggregator': '0x9645C7de2DBe8AAda01868cAa393cB7e5253268c' (uses 30 bp uni pool),
 'atomicMaxVolumePerBlock': 5m$,
 'atomicExchangeFeeRate': 0 bp}

Motivation

The primary motivation is to boost the atomic exchange volume, taking into account protection against latency attacks via the curve slippage.
