SCCP-135: Open Account Merging Continuously

Simple Summary

Make Account Merging always possible in order to enable transferring escrowed SNX balances to a different account.

Abstract

This SCCP intends to make account merging for any escrowed SNX balance (including partial amounts) possible at any time. This changes in parameters are meant to happen on both L1 and L2.

Motivation

Not being able to merge accounts has caused several problems to stakers, such as:

• Small stakers foregoing rewards due to inability to consolidate large wallets

Less accounts staking as SNX is escrowed in wallets that are not maintained

• Limiting composability impedes using flashloans for debt repayment
• Staking pools cannot operate efficiently
• Overall worsening of UX

Implementation

The merge window on the current escrow contract needs to be extended to a very long amount of time (315360000 seconds - 10 years) making it permanent and can be extended.

• RewardEscrowV2.setMaxAccountMergingWindow(uint(315360000))
• RewardEscrowV2.setAccountMergingDuration(uint(315360000))

The escrow migration service will be able to flash loan sUSD, burn all debt, migrate SNX and optionally sell down some SNX if the ratio is below 400%. By modifying the account merge window to be always on, this functionality can be integrated into staking.synthetix.io.
