Broadcast to a Node

Pre-Req: You have the body variable with a valid signature (see prior pages).

Simulating

A good practice to have is to simulate the transaction before you actually broadcast and update the fee from the transaction context with up to date values.

To do this, you can use

https://api.bitbadges.io/api/v0/simulate

or

http://URL:1317/cosmos/tx/v1beta1/simulate

This will return the gas used on a dry run of the transaction and any errors if it finds any. You can leave all signature fields empty because simulations do not check any signatures.

Note this tutorial is slightly out of order for clarity, the simulation step should typically be done before the user signs, so they only have to sign the final Msg with the up to date gas.

export interface SimulateTxRouteSuccessResponse<T extends NumberType> {
    gas_info: {
        gas_used: string;
        gas_wanted: string;
    };
    result: {
        data: string;
        log: string;
        events: {
            type: string;
            attributes: {
                key: string;
                value: string;
                index: boolean;
            }[];
        }[];
        msg_responses: any[];
    };
}

Broadcasting

You can replace the URL below with any valid BitBadges blockchain node.

`http://URL:1317${generateEndpointBroadcast()}`

Or, you can use the BitBadges API to broadcast.

https://api.bitbadges.io/api/v0/broadcast

await BitBadgesApi.broadcastTx(body);

export interface BroadcastTxRouteSuccessResponse<T extends NumberType> {
    tx_response: {
        code: number;
        codespace: string;
        data: string;
        events: {
            type: string;
            attributes: {
                key: string;
                value: string;
                index: boolean;
            }[];
        }[];
        gas_wanted: string;
        gas_used: string;
        height: string;
        info: string;
        logs: {
            events: {
                type: string;
                attributes: {
                    key: string;
                    value: string;
                    index: boolean;
                }[];
            }[];
        }[];
        raw_log: string;
        timestamp: string;
        tx: object | null;
        txhash: string;
    };
}
