There has been two attempts at bridging CryptoNote coins and Ethereum blockchain before.
Talleo Project has launched own bridge on Rinkeby testnet of Ethereum and at the same time is working on equivalent Tron bridge on Nile testnet.
The bridge uses payment ID field of CryptoNote transactions to transcode destination Ethereum address and transcodes Talleo address in contract parameters when converting from wrapped TLO back to TLO.
Main purpose of Ethereum bridge is to allow trading CryptoNote coins on decentralized exchanges and implement payments on smart contract based games.
The Ethereum network is constantly updated, which tends to improve its performance and increase its long-term functionality. Without a doubt Talleo and Ethereum are great pairs
Performance on Ethereum network depends on used transaction fee (gas)... Bridge is configured to use about twice the amount of gas that is required to get the transactions accepted to blockchain. Using more than twice defeats the purpose of Talleo Project as it's supposed to be fast and low fee...
