Check Your ETHs/ERC20s/NFTs Balance

View smart contract details on layer 1

After you have your smart contract address, you can view your contract detail through etherscan.io.

If you are deploying to Sepolia Network, you can view your contract at https://sepolia.etherscan.io/address/{your_smart_contract_address}

If you are deploying to Görli Network(deprecated), you can view your contract at https://goerli.etherscan.io/address/{your_smart_contract_address} .

If you are deploying to mainnet, you can view your contract at https://etherscan.io/address/{your_smart_contract_address}.

For example, if your smart contract address is 0x4240e8xxxxxxxxxxxxxxxxx1 and you are using sepolia network.

A valid URL would be https://sepolia.etherscan.io/address/0x4240e8xxxxxxxxxxxxxxxxx1.

View ETH/ERC20 balance on layer 2

You can query the ETH/ERC20 balance with RedSonic’s API through https://api-dev.reddio.com/v1/balances?stark_key={your_starkkey}.

Carefully replace {your_starkkey} with your own stark_key. Suppose your stark_key is 0x761f170xxxxxxxxxxxxxxxxxxxxxxxxxxxfbd39accda.

A valid URL would be https://api-dev.reddio.com/v1/balances?stark_key=0x761f170xxxxxxxxxxxxxxxxxxxxxxxxxxxfbd39accda.

You will see your ETH/ERC20 balance with type “ETH” and “ERC20“, a sample response will be looked like this:
