Using LavaSDK

🛡️ The Backend​

☠️ The Problem: Making calls to API providers is computationally expensive. Creating a backend application requires generating a private key locally and maintaining a sufficient balance to make calls on multiple chains.

✅ The Solution: Lava simplifies multi-chain backend development with free subscriptions on all projects through our gateway. Lava allows any user to sign up to the gateway. A default subscription is provided courtesy of Lava and requires no additional configurations. This subscription is rate-limited but should be substantial enough for many use cases.

🚀 Get Started: You can get started right from the Lava Gateway! We recognize that a hosted solution for project/subscription management is not ideal for all users and some may want more granular control of subscriptions or limits. Users who are interested in self-custodial project management should learn more about subscriptions.

Although you can subscribe your private key from the commandline, the easiest way to get started is through Lava's Gateway.

  1. Sign up to the Gateway. 👉🏿Register now if you haven’t already!

  2. Create a Project and Select your APIs!

  3. Go to Settings -> Project Keys

  4. Click Add New Key and decide whether you want to Generate a new Key or Add a public Key

  5. Give a moment for your key to sync!

SynchingKey

  1. Install the SDK into your project -> npm install @lavanet-lava-sdk

  2. Select any of your API accesses (LavaSDK -> Use in BackEnd) & copy & paste your code snippet into your code.


🔑 Manual Key Creation​

A private-key, public-key pair can also be generated using our lavad binary. The installation guide can be very helpful for users looking to use lavad.For more information on how to create a lava address consult the existing documentation.

If you already have lavad installed - you can easily generate a lava address by entering the following command: lavad keys add <keyname>

If you have an address that exists and no longer remember its private key, you can alwasy use lavad keys export <key-name> --unarmored-hex --unsafe to see your privatekey printed as a string. Do not share the output with anyone!

🚀 Your private-key, public-key pair can be used for backend development provided you have a subscription!
