 **Note on Internal Transfers**
 
-Internal transfers are currently supported on Ethereum (Mainnet, Sepolia), Polygon (Mainnet, Amoy), Arbitrum (Mainnet, Sepolia), Optimism (Mainnet, Sepolia), Base (Mainnet, Sepolia), BNB Chain (Mainnet, Testnet), Avalanche (Mainnet, Fuji), and Robinhood Chain (Mainnet, Testnet). Support for other networks is a work in progress. Reach out if you need internal transfer support for a chain not listed above.

 Internal Transfers with the call type `delegatecall` are not supported on Alchemy. Although they have a value associated with them, they don't transfer a value. For details read the [Ethereum Yellow Paper](https://ethereum.github.io/yellowpaper/paper.pdf). Internal transfer miner rewards are also unsupported on Alchemy.
