Amir Chetrit is a developer who became involved in the blockchain industry prior to the creation of Ethereum. He was working on a project called Colored Coins, which aimed to manage real-world assets as tokens on the Bitcoin network. In 2013, he met Vitalik Buterin at a Bitcoin conference in Amsterdam and invited him to join the project. However, due to a lack of involvement in Ethereum, Chetrit agreed to step down as a co-founder during a meeting with the Ethereum developers in June 2014. Despite supporting various blockchain projects, Chetrit prefers to keep a low profile and avoid public attention.
