Answer:Trust wallet's OETH (optimism ETH) is a way to distinguish ETH on mainnet from ETH on the Optimism sidechain. This is because ETH on the Optimism sidechain is a different asset than ETH on the mainnet. As such, it is listed as OETH in Trust Wallet to differentiate it from ETH on the mainnet. OETH is a tokenized version of ETH that is designed to make transactions faster and more secure. OETH is also more cost-effective than ETH on the mainnet, as it is not subject to the same fees and costs associated with ETH on the mainnet. Additionally, OETH can be used to interact with decentralized applications on the Optimism sidechain, such as DeFi applications. As such, it is important to understand the differences between OETH and ETH on the mainnet when using Trust Wallet.
