SingleSigner::new

Construct a bare SingleSigner with both user_index and nonce undefined.

Signature

impl<S: Secret> SingleSigner<S, Undefined<UserIndex>, Undefined<Nonce>> {
    pub fn new(address: Addr, secret: S) -> Self;
}

Example

use {
    anyhow::Result,
    dango_sdk::{Secp256k1, Secret, SingleSigner},
    grug::Addr,
    std::str::FromStr,
};
 
fn build() -> Result<SingleSigner<Secp256k1, _, _>> {
    let address = Addr::from_str("0x0000000000000000000000000000000000000000")?;
    let secret  = Secp256k1::new_random();
    Ok(SingleSigner::new(address, secret))
}

Parameters

address — Addr. The on-chain account address.

secret — S: Secret. The private key.

Returns

SingleSigner<S, Undefined<UserIndex>, Undefined<Nonce>> — fill both slots with with_user_index/with_nonce (or their with_query_* async variants) before signing.

Notes

  • This is the canonical entry point when the caller already knows the address. To discover an address from a key, use new_first_address_available.
  • Sets user_index and nonce to Undefined::new(). The compiler refuses sign_transaction until both are Defined.
