Proposal Summary

This XIP proposes the upgrade of the Infinex Account to the next version, with the ability to send assets to a specified address and allowing users to update their recovery address.

Specification

Overview

We propose the following changes to the Infinex account:

• The ability to send assets to a specified address, as long as the Infinex platform co-signs the transactions
• Allow users to update their recovery address, also requires Infinex platform co-signing.

These two changes supercedes Send V1, and previous related security updates. They will be implemented as Account Upgrade V4 (EVM) and V3 (Solana).In addition, the EVM account upgrade will also include:

• EIP1271 smart contract signing support for Main Accounts
• Functions to support ERC721A and Cryptopunks/Etherrocks
• The Curve Stable Swap App to include support for legacy ERC-20 tokens.

Rationale

Sending assets to any specified address

This feature was proposed in the XIP-39: Send V1, however has been superseded by this XIP. The new proposed implementation of Send V2 will provide greater flexibility, as well as solving challenges with cross-chain address book syncing.

Updating the Recovery Address

One of the biggest quality of life improvements Infinex can make is allowing users to update their recovery address - this will allow users to continue to use funds recovery functionality if they lose access to their existing funds recovery address.

EIP1271

As support for smart contract signing improves, this allows users to validate that they are the owner of an Infinex account when integrating with third parties that require EOA signatures for things such as claims.

ERC721A & Other NFT Support

This extends both support for legacy NFTs that do not conform to the NFT standard, as well as adding batch transfer functionality (ERC721A, such as the Patron NFT), which will see significant gas savings when transferring multiple NFTs.

Curve Stable Swap Updates

The update will allow Curve Stableswap pools that include legacy ERC20 tokens that do not conform to the ERC20 standard
