# Class diagram for new explicit session config utilities

Reviewer's Guide

Implements new dapp-client utilities to build explicit session configs (including native token spending controls) and re-exports additional primitives for EOA login flows, extends login methods to support EOA, adjusts Apple OAuth handling to omit the scope parameter, and bumps multiple package versions and changelogs to 3.0.0-beta.9 with associated changesets.

File-Level Changes

Change	Details	Files
Add utilities and exports in dapp-client to construct explicit session configs and expose network/relayer helpers and constants for consumers.	Introduce SessionDuration, NativeTokenSpending, and ExplicitSessionParams types to model explicit session configuration inputs, including optional native token spending constraints.Implement createExplicitSessionConfig to derive ExplicitSessionConfig from human-friendly params, computing a deadline from the current time and duration, enforcing at least one base permission, and merging permission entries for allowed native token recipients and value limits.Update imports to include ExplicitSessionConfig and Permission from wallet-core/wallet-primitives, add Address type from ox, and re-export VALUE_FORWARDER_ADDRESS from constants.Expand dapp-client public API exports to include createExplicitSessionConfig, getNetwork, getRelayerUrl, getRpcUrl, VALUE_FORWARDER_ADDRESS, new session-related types, Network, MessageType, and TransportMessage.	packages/wallet/dapp-client/src/utils/index.tspackages/wallet/dapp-client/src/index.ts
Extend login support to EOA and adjust Apple auth OAuth behavior to be compatible with provider expectations.	Add 'eoa' as a supported LoginMethod option for the dapp client.Modify AuthCodeHandler to omit the OAuth scope parameter when signupKind is 'apple', while preserving existing behavior for other providers.Update Apple-specific authcode test to assert that the generated authorization URL does not contain the scope query parameter.	packages/wallet/dapp-client/src/types/index.tspackages/wallet/wdk/src/sequence/handlers/authcode.tspackages/wallet/wdk/test/authcode.test.ts
Publish 3.0.0-beta.9 patch release across core, dapp-client, primitives, WDK, and various services with Apple auth fixes, EOA login updates, and dependency bumps.	Add 3.0.0-beta.7 to 3.0.0-beta.9 entries to multiple CHANGELOGs describing Apple auth fixes, dapp-client EOA login updates, and dependency updates across guard, identity-instrument, relayer, wallet-core, and wallet-primitives.Bump versions from 3.0.0-beta.6 to 3.0.0-beta.9 in package.json files for services, utils/abi, wallet-core, dapp-client, wallet-primitives, and wallet-wdk packages.Introduce changeset files documenting patch releases for Apple auth fixes and dapp client updates for EOA login across affected packages.Update pre-release changeset configuration to include the new changesets.	packages/wallet/wdk/CHANGELOG.mdpackages/wallet/dapp-client/CHANGELOG.mdpackages/wallet/core/CHANGELOG.mdpackages/services/relayer/CHANGELOG.mdpackages/services/api/CHANGELOG.mdpackages/services/builder/CHANGELOG.mdpackages/services/guard/CHANGELOG.mdpackages/services/identity-instrument/CHANGELOG.mdpackages/services/indexer/CHANGELOG.mdpackages/services/marketplace/CHANGELOG.mdpackages/services/metadata/CHANGELOG.mdpackages/services/userdata/CHANGELOG.mdpackages/utils/abi/CHANGELOG.mdpackages/wallet/primitives/CHANGELOG.mdpackages/services/api/package.jsonpackages/services/builder/package.jsonpackages/services/guard/package.jsonpackages/services/identity-instrument/package.jsonpackages/services/indexer/package.jsonpackages/services/marketplace/package.jsonpackages/services/metadata/package.jsonpackages/services/relayer/package.jsonpackages/services/userdata/package.jsonpackages/utils/abi/package.jsonpackages/wallet/core/package.jsonpackages/wallet/dapp-client/package.jsonpackages/wallet/primitives/package.jsonpackages/wallet/wdk/package.json.changeset/pre.json.changeset/new-turkeys-double.md.changeset/nice-tips-slide.md.changeset/tiny-files-chew.md
