    fn key(&self) -> SigningKey;
}

Expand description

Trait for signing transactions.

A signer knows which account it signs for and provides keys for signing. The key() method returns a SigningKey that bundles together the public key and signing capability, ensuring atomic key claiming.

§Example Implementation

use near_kit::{Signer, SigningKey, AccountId, SecretKey};

struct MyCustomSigner {
    account_id: AccountId,
    secret_key: SecretKey,
}

impl Signer for MyCustomSigner {
    fn account_id(&self) -> &AccountId {
        &self.account_id
    }

    fn key(&self) -> SigningKey {
        SigningKey::new(self.secret_key.clone())
    }
}
