Gargantua

Endpoints and example requests for Gargantua, the Hyperbridge test network.

Hyperbridge (short for hyper-scalable bridge) is innovated as a cross-chain solution built as an interoperability coprocessor. Hyperbridge is crafted to scale cryptographically secure, consensus, and state-proof-based interoperability across all blockchains.

How to Connect to Gargantua

Using Private Endpoint

Using API keys on an RPC node provides better tracking and monitoring of API usage.

Secure your data, speed up your queries, and take control of your API usage with our RPC API endpoint and personalized API keys. Sign up now to get your own API key.

To get your API key, create a project using a unique Identifier as the project name and select Gargantua from the network options.

Send requests

All requests are POST requests.

Connect via Command Line

You can connect to the network using websocket or HTTP with your API key in two ways:

• Adding the API key as a query string ?api_key=${APIKEY}
• Or the request header -H 'authorization: APIKEY ${APIKEY}'

Curl

For example, the following CURL command can be used to get header and body of a relay chain block.

curl -H "Content-Type: application/json" -H 'authorization: APIKEY xxxx'  -d '{"id":1, "jsonrpc":"2.0", "method": "chain_getBlock"}' https://gargantua-rpc.blockops.network/rpc

Here is the response you will receive back.

Wscat

If you want to send data requests with WebSockets, you can use several libraries or wscat. You can install and use wscat as follows:

• Download wscat from https://www.npmjs.com/package/wscat
• Install wscat by running the following command: npm install -g wscat

You can connect to the network with wscat using two options by adding the API key as a query string.

wscat -c 'wss://gargantua-rpc.blockops.network/ws?api_key=*********************'

Or the request header.

wscat -c 'wss://gargantua-rpc.blockops.network/ws' --header 'authorization: APIKEY xxxx'

After executing the command, the terminal will display a message indicating that the connection has been enabled successfully.

Connected (press CTRL+C to quit)

Then, you can send the following request:

{"id":1, "jsonrpc":"2.0", "method": "chain_getBlock"}
