SingleSigner::with_query_nonce

Fetch the next unused nonce from the account and return a SingleSigner with nonce defined.

Signature

impl<S: Secret, I: MaybeDefined<UserIndex>> SingleSigner<S, I, Undefined<Nonce>> {
    pub async fn with_query_nonce<C>(
        self,
        client: &C,
    ) -> anyhow::Result<SingleSigner<S, I, Defined<Nonce>>>
    where
        C: QueryClient,
        anyhow::Error: From<C::Error>;
}

Example

use {
    anyhow::Result,
    dango_sdk::{HttpClient, Secp256k1, SingleSigner},
    grug::Addr,
    std::str::FromStr,
};
 
#[tokio::main]
async fn main() -> Result<()> {
    let http = HttpClient::new("https://api-mainnet.dango.zone")?;
    let signer = SingleSigner::new(
        Addr::from_str("0x0000000000000000000000000000000000000000")?,
        Secp256k1::new_random(),
    )
    .with_query_user_index(&http).await?
    .with_query_nonce(&http).await?;
    let _ = signer;
    Ok(())
}

Parameters

client — &C implementing QueryClient.

Returns

SingleSigner<S, I, Defined<Nonce>> — the same signer with the nonce populated from the chain.

Notes

  • Reads QuerySeenNoncesRequest on the account contract; returns last_seen + 1, or 0 if the account has never signed.
  • Errors propagate from QueryClient::Error via anyhow::Error: From<C::Error>.
