Struct SmartSigner 

pub struct SmartSigner<'a> { /* private fields */ }

Smart signer with auto-version tracking (matching Dart SDK SmartSigner)

Implementations

impl<'a> SmartSigner<'a>

pub fn new( client: &'a AccumulateClient, keypair: SigningKey, signer_url: &str, ) -> Self

Create a new SmartSigner

pub async fn refresh_version(&mut self) -> Result<u64, JsonRpcError>

Query and update the cached version

pub fn version(&self) -> u64

Get the current cached version

pub fn sign( &self, principal: &str, body: &Value, memo: Option<&str>, ) -> Result<Value, JsonRpcError>

Sign a transaction and return the envelope

This uses proper binary encoding matching the Go core implementation:

1. Compute signature metadata hash (binary encoded)
2. Use that as the transaction initiator
3. Compute transaction hash using binary encoding
4. Create signing preimage = SHA256(sigMdHash + txHash)
5. Sign the preimage

pub async fn sign_submit_and_wait( &mut self, principal: &str, body: &Value, memo: Option<&str>, max_attempts: u32, ) -> TxResult

Sign, submit, and wait for transaction confirmation

pub async fn add_key(&mut self, public_key: &[u8]) -> TxResult

Add a key to the key page using SmartSigner

pub async fn remove_key(&mut self, public_key_hash: &[u8]) -> TxResult

Remove a key from the key page using SmartSigner

pub async fn set_threshold(&mut self, threshold: u64) -> TxResult

Set the threshold for the key page

Trait Implementations

impl<'a> Debug for SmartSigner<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
