ERC7412 has been used by Synthetix to allow users to push their own price updates to complete on-chain operations.

The protocol has been difficult to maintain as the number of markets have increased on the perps platform, and it is no longer possible/practical to apply price updates using the reccomended call pattern due to hundreds of necessary simulation calls,

To resolve this problem, ERC7412 errors will now be returned in large batches.

A summary of the interface changes to ERC7412 can be on the reference impl repo.

Explanation of Changes

Findings:

[CRITICAL[ infinite money printing glitch (see below)
- Fixed by fixing bug in AssociateDebt module which allowed for markets which were not in range to assign debt to an account. Tests added. https://github.com/Synthetixio/synthetix-v3/commit/eea624a739090ff5ace028de4ea25ffc1c926e96
[CRITICAL] LegacyMarket.sol does not implement the onERC721Received function. As a result, calling migrate will always revert as minting an account token to itself will fail.
- added onERC721Received function https://github.com/Synthetixio/synthetix-v3/commit/5fe3425b23b3c0c6e21cbab42b25f7832fcfde54
[CRITICAL] Accounts with an unhealthy collateralization ratio cannot be migrated. During migration, the call to associateDebt will validate that the debt association does not put the account into a state that can be liquidated. As a result, an account on v2 that should be liquidated cannot be moved to v3 if the collateralization ratios are the same between the two systems.
