Fraxtal LayerZero <> Curve AMO

Introduction

Frax AMO to manage LayerZero-bridged Frax assets to Fraxtal. When bridging via LayerZero, the token received on Fraxtal is not the same as the chain-native token (ie. LZ-branded sFRAX != Fraxtal-native sFRAX). This AMO manages a Curve pool of LZ-asset <> Native-asset to automatically swap the LZ asset into native asset upon bridging. Therefore, a bridger is able to atomically receive Fraxtal-native sFRAX while using the LayerZero bridge, maintaining the low gas fees and high speed offered by LayerZero.

TODO (non-exhaustive)

• Deploy Curve pools
• Execute immediate curve swap upon bridge
• Determine action if amount received upon swap < amount desired
• AMO
  • Determine threshold to trigger rebalance
  • Manage liquidity when LZ sFRAX > native sFRAX
  • Manage liquidity when LZ sFRAX < native sFRAX
• FE
