Currently, that's what we have on main:

File | % Stmts | % Branch | % Funcs | % Lines | Uncovered Line #s
----------------------|---------|----------|---------|---------|------------------------------
All files | 99.04 | 95.09 | 100 | 99.03 |

errors.ts | 100 | 100 | 100 | 100 |
----------------------|---------|----------|---------|---------|------------------------------And the new coverage is like this:
----------------------|---------|----------|---------|---------|------------------------------
File | % Stmts | % Branch | % Funcs | % Lines | Uncovered Line #s
----------------------|---------|----------|---------|---------|------------------------------
All files | 99.12 | 94.91 | 100 | 99.11 |

errors.ts | 100 | 100 | 100 | 100 |
----------------------|---------|----------|---------|---------|------------------------------Same number of lines not covered, so nothing has changed in terms of coverage.

Explanation
Another approach for
withKeyringV2where we actually extend the existing list of keyring instances to have an optionalkeyringV2field.This allow to keep them in memory and have the same lifecycle than v1 keyring instance (and since all v2 implementations are wrappers for now, they are "bound" to v1 instances anyway).
Original PR:

N/A
Checklist
Note
Medium Risk
Introduces new V2 keyring selection/execution paths and caches V2 adapters alongside legacy keyrings, which could affect keyring lifecycle, rollback/persistence behavior, and error handling. Dependency bumps to keyring packages may also subtly change signing/account behavior.
Overview
Adds first-class
KeyringV2support by storing an optional in-memory V2 adapter next to each legacy keyring entry and creating/destroying these adapters during keyring create/restore/clear flows.Introduces
withKeyringV2(locked, persisted/rollback) andwithKeyringV2Unsafe(lock-free, no rollback) APIs plus messenger action types, including a newKeyringSelectorV2(type/address/id/filter) and aKeyringV2NotSupportederror when no V2 builder exists for a selected keyring.Updates tests to cover selector variants, lock/rollback semantics, and messenger callability; bumps
@metamask/eth-hd-keyring/@metamask/eth-simple-keyringversions and adjusts Jest coverage thresholds accordingly.Reviewed by Cursor Bugbot for commit d8bc565. Bugbot is set up for automated code reviews on this repo. Configure here.
