The popular DeFi protocol Uniswap v3 has been deployed on Arbitrum mainnet. Arbitrum is one of the leading open-source platforms developing Optimistic Rollups.
The implementation was announced on Twitter by the official Uniswap account yesterday:
In a very convincing governance poll, UNI token holders decided to deploy Uniswap v3 on Arbitrum mainnet.
At first, v3 was supposed to launch on Optimism – another Optimistic Rollups protocol. However, Optimism’s mainnet launch was postponed to July. Uniswap seems to take a multi-chain path, launching on various different second layer solutions to increase transactions per second and lower transaction fees.
Today, Arbitrum is in whitelist mode only. Uniswap commented the following:
“Arbitrum is currently in whitelist only mode. Once it opens to all users, Uniswap v3 will work out of the gate with no additional work required. Developers who are currently whitelisted can use this deployment immediately!”Uniswap
That means only whitelisted developers can access the protocol as of now. According to Arbitrum, this could change in the near future!
