Ethereum (ETH) is a cryptocurrency that supports smart contracting functionality through a turing-complete scripting language called Solidity. The Ethereum network went live on 30 July 2015. Development of Ethereum was funded through an online crowdsale in which 11.9 million coins (ETH) were distributed prior to the launch of the network.
How to use Ethereum with Trezor
Even though Ethereum is currently not integrated in Trezor Wallet (although work is in progress to change that soon), it can be safely used with certain third-party wallets and services, with the seed and private keys fully protected by the Trezor device. These include MyEtherWallet and MyCrypto. For more information about other third-party services, see Apps.
