Chains supported by the Wallet.

A chain is an IdentifierString which identifies a blockchain in a canonical, human-readable format. CAIP-2 chain IDs are compatible with this, but are not required to be used.

Each blockchain should define its own chains by extension of the Wallet Standard, using its own namespace. The standard and experimental namespaces are reserved by the Wallet Standard.

The standard:events feature should be used to notify the app if the value changes.

Features supported by the Wallet.

A feature name is an IdentifierString which identifies a feature in a canonical, human-readable format.

Each blockchain should define its own features by extension of the Wallet Standard.

The standard and experimental namespaces are reserved by the Wallet Standard.

A feature may have any type. It may be a single method or value, or a collection of them.

A conventional feature has the following structure:

 export type ExperimentalEncryptFeature = {
     // Name of the feature.
     'experimental:encrypt': {
         // Version of the feature.
         version: '1.0.0';
         // Properties of the feature.
         ciphers: readonly 'x25519-xsalsa20-poly1305'[];
         // Methods of the feature.
         encrypt (data: Uint8Array): Promise<Uint8Array>;
     };
 };

The standard:events feature should be used to notify the app if the value changes.

Accounts that the app is authorized to use.

This can be set by the Wallet so the app can use authorized accounts on the initial page load.

The standard:connect feature should be used to obtain authorization to the accounts.

The standard:events feature should be used to notify the app if the value changes.
