What project is Alchemy?

In December 2019, Alchemy completed $15 million Series A financing, the owners are Pantera Capital, Stanford University, Coinbase, Samsung, etc.

In April 2021, Alchemy completed its US$80 million Series B round of financing at a valuation of US$505 million, led by Coatue and Addition DFJ Growth, K5 Global, Chainsmokers (smoker combination), actor Jared Leto and the Glazer family participated in the vote.

In October 2021, Alchemy completed $250 million Series C financing at a valuation of $3.5 billion, led by a16z.

In February 2022, Alchemy completed a $200 million financing round at a $10.2 billion valuation, led by Lightspeed and Silver Lake.

Alchemy is a team with a strong background, sufficient funds, practical work, and no currency issuance.

And, Alchemy plans to use the new funds to promote Web3 adoption, some of which include the launch of Web3 University, now Road to Web3 10 weeks, one NFT per week. After looking at the very small number of NFTs, it is estimated that due to the difficulty of the task, many small partners simply gave up. If such a project is airdropped, it is definitely a big deal.
