FAQPage Schema

How do I fetch wallet balances and token holdings across multiple EVM networks?▼

To fetch wallet balances and token holdings across EVM networks, you can use plain HTTP requests to retrieve ETH, token, and NFT balances for addresses on chains like eth-mainnet, base-mainnet, and polygon-mainnet.

Can I get real-time token prices and gas data without installing an SDK?▼

Yes, you can retrieve real-time token prices and gas data without an SDK by making plain HTTP requests to the price and gas API endpoints using your ALCHEMY_API_KEY.

What EVM networks are supported for checking address balances and asset transfers?▼

Supported EVM networks for checking address balances and asset transfers include eth-mainnet, base-mainnet, polygon-mainnet, arb-mainnet, and opt-mainnet.

How do I simulate a transaction to preview asset changes before sending?▼

You can simulate a transaction to preview asset changes before sending by using the simulate function, which evaluates the transaction impact on wallet balances without broadcasting it.

Do I need an Alchemy API key to retrieve NFT ownership and transfer history?▼

Yes, you need an ALCHEMY_API_KEY to retrieve NFT ownership and transfer history, as this key authorizes the plain HTTP requests to fetch the blockchain data.

Is there a way to inspect full asset transfer history for a specific wallet address?▼

You can inspect full asset transfer history for a specific wallet address by calling the transfers function, which retrieves historical asset movement records across supported EVM networks.
