Struct CustodyServiceClient

Source 
pub struct CustodyServiceClient<T> { /* private fields */ }
Available on crate feature rpc only.
Expand description

The custody protocol is used by a wallet client to request authorization for a transaction they’ve constructed.

Modeling transaction authorization as an asynchronous RPC call encourages software to be written in a way that has a compatible data flow with a “soft HSM”, threshold signing, a hardware wallet, etc.

The custody protocol does not trust the client to authorize spends, so custody requests must contain sufficient information for the custodian to understand the transaction and determine whether or not it should be authorized.

Implementations§

Source

pub fn send_compressed(self, encoding: CompressionEncoding) -> Self

Default: usize::MAX

Source

pub async fn authorize( &mut self, request: impl IntoRequest<AuthorizeRequest>, ) -> Result<Response<AuthorizeResponse>, Status>

Requests authorization of the transaction with the given description.

Source

pub async fn authorize_validator_definition( &mut self, request: impl IntoRequest<AuthorizeValidatorDefinitionRequest>, ) -> Result<Response<AuthorizeValidatorDefinitionResponse>, Status>

Requests authorization of the given validator definition update.

Source

pub async fn authorize_validator_vote( &mut self, request: impl IntoRequest<AuthorizeValidatorVoteRequest>, ) -> Result<Response<AuthorizeValidatorVoteResponse>, Status>

Source

pub async fn export_full_viewing_key( &mut self, request: impl IntoRequest<ExportFullViewingKeyRequest>, ) -> Result<Response<ExportFullViewingKeyResponse>, Status>

Requests the full viewing key from the custodian.

Custody backends should decide whether to honor this request, and how to control access to it.

Source

pub async fn confirm_address( &mut self, request: impl IntoRequest<ConfirmAddressRequest>, ) -> Result<Response<ConfirmAddressResponse>, Status>

Displays an address to a user for confirmation.

Custody backends with user interaction should present the address to the user and wait for explicit confirmation before returning.

Non-interactive custody backends may return immediately.
