Arka testnet Usage

​

Using Arka

When estmiating a transaction with the SDK on testnets we support we can pass in the testnet api key value as ‘etherspot_public_key’ and set the mode of the transaction to be sponsored like so:

const op = await primeSdk.estimate({ 
    url: "https://rpc.etherspot.io/paymaster?apiKey=etherspot_public_key&chainId=11155111",
    context: { mode: 'sponsor' } 
    });

​

Supported testnets

• Sepolia
• Base Sepolia
• Scroll Sepolia
• Fuse Sparknet
• Ancient8 Testnet
• Flare Coston2
• Rootstock testnet

This will use testnet funds and a paymaster we have specifically setup for devs to test out before trying sponsored transactions on mainnet.
