mina_sendTransaction

This method is used for sign and broadcast zkApp transaction.

You need to create zk commond in zkApp first, then call Auro Wallet to sign and broadcast.

Params

interface SendTransactionArgs  {
    // only sign with auro wallet, auro-extension-wallet support from V2.2.16. 
    readonly onlySign?: boolean; 
    // custom nonce with auro wallet, auro-extension-wallet support from V2.3.0. 
    readonly nonce?: number; 
    // transaction is zk commond that create by contract.
    readonly transaction: string | object;
    // option. 
    readonly feePayer?: {
        // option. Auro Wallet also provide advance option to change fee.
        readonly fee?: number;
        // option.
        readonly memo?: string;
    };
}

Result

type SendTransactionHash = {
    // broadcast hash, you can query tx info by this hash.
    hash: string;
};

type SignedZkappCommand = {
    // results of JSON.stringify( signZkappCommand().data )
    signedData: string; 
};

type SendZkTransactionResult = SendTransactionResult | SignedZkappCommand

interface ProviderError extends Error {
    message: string; // error message.
    code: number; // error code.
    data?: unknown; // error body. 
}

Promise<SendTransactionResult | ProviderError>
