 ## Multichain Considerations
 
-Developers addressing multichain use-cases incorporating non-Solana networks are RECOMMENDED to use distinct [CAIP-217] authorization objects per chain type, in cases where those [CAIP-25] capabilities and configurations can be deterministically mapped to [Wallet Standard Multichain Extensions] variables by a [CAIP-25] provider.

 Also, consumers of the [Wallet Standard][] interface assume the `WalletAdapterNetwork` enum variable to be set to exactly one network at a time, so implementers are recommended to map only one `chains` member at a time to this standard interface, whether by ordering it by preference or by never allowing it to have more than one member at a time.
 
-## Session Properties
+## Setting Environmental Variables to pass via Wallet Standard
 
-Wallet capabilities in the [Wallet Standard] model are declared upfront at time of connection and persisted as read-only constants, so wallets are recommended to declare them explicitly in the `sessionProperties` object in a [CAIP-25] interaction for maximum interoperability and stability.
-Note that the `sessionProperties` object is shared across any and all namespaces in a given wallet<>application session, which may span multiple types of networks all declaring `sessionProperties`, so to avoid collisions the following properties names are recommended for easily mapping to the **case-sensitive** properties names in the [Wallet Standard]:
+Wallet capabilities in the [Wallet Standard] model are declared upfront at time of connection and persisted as read-only constants.
+For maximum interoperability and stability, wallets are recommended to declare these variables explicitly in the `scopedProperties` object corresponding to each Solana scope they authorize when accepting a [CAIP-25] connection.
+Note that the `scopedProperties` object is partitioned to parallel the `sessionScopes`, so duplicate entries need to be made for each Solana scope.

-As these properties are mandatory and required for stability in [Wallet Standard] connections, [CAIP-25] providers MAY inject defaults if any of the above are not set explicitly by a wallet.
-For this reason, wallets are RECOMMENDED to set them explicitly even if not requested by their counterparty to avoid inaccurate values being injected.
