The Ethereum network underwent a major upgrade in September 2022, moving from a proof-of-work (PoW) to a proof-of-stake (PoS) network in an event called the Merge.
According to on-chain data shared by crypto analytics firm Santiment, the amount of available ETH sitting on exchanges continues to fall. Since the Merge, there is 37% less ETH on exchanges.
There was a total of 19.12 million ETH, worth $31.3 billion, on exchanges in September before the Merge.
