Major cryptocurrency investment firm Grayscale has finally decided to relinquish all rights to its post-merger proof-of-work (PoW) Ethereum token (ETHPoW).

Grayscale announced this news on September 18 explain The company has “irrevocably waived” all rights to the ETHPoW tokens on behalf of each offering’s record date shareholders.

After a thorough review, Grayscale determined that the ETHPoW token has not yet developed meaningful liquidity and that the product custodian does not support such tokens. The company wrote:

“Accordingly, it is not possible to exercise its rights to acquire and sell ETHPoW tokens, and on behalf of record date shareholders, Grayscale waives its rights to these assets.”

Grayscale’s decision to relinquish rights to the ETHPoW token comes more than a year after the Ethereum merger, an event that marked Ethereum’s full transition from PoW to Proof of Stake (PoS). The merger took place on September 15, 2022, forking the Ethereum blockchain into Ethereum, which is primarily PoS-based, and Ethereum, which is secondary PoW-based.

Following the merger, Grayscale is considering whether the company should acquire EthereumPoW and sell ETHW on behalf of record-date shareholders. 180 days after the merger, the company took another six months to decide whether to acquire these PoW tokens, citing uncertainty about support for ETHW tokens from digital asset custodians and trading venues.
