## @metamask/chain-agnostic-permission ## [1.6.0] ### Added - Add `Eip1193Compatible` property in `KnownSessionProperties` enum to support EIP-1193-style connections established through `connect-evm` ([#8731](#8731)) - Set `sessionProperties: { 'eip1193-compatible': true }` in `getCaip25PermissionFromLegacyPermissions` so that legacy EIP-1193 permission requests are tagged as EIP-1193-compatible ([#8731](#8731)) ### Changed - Bump `@metamask/permission-controller` from `^12.2.1` to `^13.1.0` ([#8317](#8317), [#8661](#8661), [#8722](#8722)) - Bump `@metamask/controller-utils` from `^11.19.0` to `^11.20.0` ([#8344](#8344)) ## @metamask/multichain-api-middleware ## [3.1.0] ### Changed - Bump `@metamask/chain-agnostic-permission` from `^1.5.0` to `^1.6.0` ([#8290](#8749)) - Bump `@metamask/multichain-transactions-controller` from `^7.0.4` to `^7.1.0` ([#8665](#8665)) - Bump `@metamask/accounts-controller` from `^37.2.0` to `^38.0.0` ([#8665](#8665)) - Bump `@metamask/permission-controller` from `^13.0.0` to `^13.1.0` ([#8722](#8722)) - Bump `@metamask/json-rpc-engine` from `^10.3.0` to `^10.4.0` ([#8746](#8746)) <!-- CURSOR_SUMMARY --> --- > [!NOTE] > **Low Risk** > Primarily version/changelog updates and dependency range bumps; no functional source changes are included in this diff, so runtime risk is low aside from typical release packaging/versioning issues. > > **Overview** > Bumps the monorepo release version to `971.0.0` and publishes new package versions for `@metamask/chain-agnostic-permission` (`1.6.0`) and `@metamask/multichain-api-middleware` (`3.1.0`). > > Updates changelogs and lockfile, and bumps downstream dependencies (`@metamask/eip1193-permission-middleware` and `@metamask/multichain-api-middleware`) to consume `@metamask/chain-agnostic-permission@^1.6.0`. > > <sup>Reviewed by [Cursor Bugbot](https://cursor.com/bugbot) for commit 90d6560.

Explanation
The
@metamask/connect-evmpackage is adding support for sendingsessionProperties: { 'eip1193-compatible': true }on everywallet_createSessionrequest (MetaMask/connect-monorepo#285). This lets the wallet distinguish EIP-1193-style connections established throughconnect-evmfrom pure Multichain API connections and other provider types like Solana Wallet Standard.However, the
chain-agnostic-permissionpackage validates session properties against a known set (KnownSessionPropertiesenum), and any unrecognized property causes the CAIP-25 caveat validator to throw. Without this change, the neweip1193-compatiblesession property would be rejected.This PR adds
Eip1193Compatible = 'eip1193-compatible'to theKnownSessionPropertiesenum so the wallet accepts it as a valid session property.References

Note
Low Risk
Low risk: adds a new allowed CAIP-25
sessionPropertieskey and tags legacy permission conversions with it, with no changes to scope/account validation logic beyond accepting this new flag.Overview
Adds support for the
eip1193-compatibleCAIP-25 session property by extendingKnownSessionPropertiesand related validation/tests sowallet_createSessionrequests carrying this flag are no longer rejected.Updates
getCaip25PermissionFromLegacyPermissionsto always setsessionProperties: { 'eip1193-compatible': true }, and adjusts unit tests plus the package changelog accordingly.Reviewed by Cursor Bugbot for commit fb7fa99. Bugbot is set up for automated code reviews on this repo. Configure here.
