Fireblocks now supports the newly forked EtheureumPow (ETHW) blockchain, deriving from the existent Ethereum Proof of Stake network. This new blockchain has not yet gained significant attention and we are uncertain of its market reception, so we may therefore decide to deprecate it shortly. In such a case, we will update you in advance.
The base asset is ETHW, and in order to obtain it, simply add a new asset wallet to your vault. Bear in mind that ETHW funds will only be available to you if you owned ETH tokens prior to the merge.
Note: We have not listed ERC-20 tokens since we did not identify such tokens which gained any traction. However, if you want, you can add such ERC-20 tokens on your own while linking to the Listing ERC-20 tokens article.
