Describe the Feature

May you please add BNB Smart Chain (BSC) in AlchemyProvider? And its testnets too.

Hi!
I’d like to work on this issue as my first contribution. Could you please assign it to me?

[mouhamad-almakhour]

Hi Antonio,
I added support for BNB Smart Chain (mainnet + testnet) in AlchemyProvider.
Both networks work locally — tests pass for chainId 56 (mainnet) and 97 (testnet).
Screenshot attached.

Thank you @mouhamad-almakhour ! Do you plan on pulling the PR in the main repo? Maybe @ricmoo can help us out here?

Just to give more context to this issue: alchemy-sdk is going to be deprecated and archived in January 2026 (this January). See announcement:

Warning

The Alchemy SDK JS has been deprecated and will be archived January 2026. The software will only receive minimal support until then.
[...]

So, we are going to migrate to ethers for the alchemy-sdk left-overs. However, we are blocked if the networks supported in alchemy-sdk are not the same of ethers by AlchemyProvider

Hi @AntonioVentilii ,
Yes, I plan to pull the PR into the main repo. I was just waiting for your confirmation or any other comments before doing so, so I’ll wait for @ricmoo as you suggested.
