Loopring
A blockchain research organization pioneering the future of finance. Loopring is building protocols, infrastructure, and user-facing DeFi products atop Ethereum, envisioning a digital economy that empowers its participants with full and guaranteed self-custody of their assets.
DeFi doesn't have to be a trade-off between security and performance. With this in mind, Loopring's Layer2 solutions work in synergy with Ethereum Layer1, enabling low-fee, high-speed, Ethereum-secured platforms for trustless trading, swapping, liquidity providing, and payment.
Ongoing projects led by Loopring:
-
Loopring Protocol: powered by zkRollups on Layer2, enables Ethereum to scale effectively without sacrificing Ethereum Layer1 guarantees
-
Loopring Layer2 Dex: An orderbook and automated market maker (AMM)-based non-custodial decentralized exchange (DEX) built atop Ethereum using the Loopring Protocol (v3).
-
Loopring Wallet: A mobile app for Android and iOS featuring an Ethereum Layer1 and Layer2 social recovery smart wallet.

Also.. there will be a lot less fees by doing the following
Buy USDC on coinbase -> under ~$2k clears and can send instantly, no purchase fee -> wait until low gas -> send to L1, bridge to L2 for size greater than $2k (also with points it will be free) /or/ layerswap directly to L2 -> buy desired token for less fees on L1 or L2
This can also be done in reverse. People think these on-ramps are great, but to me they are just another third party, and other CEXs have already made it easy enough to do. On-ramps are still CEXs just fyi cause I hear that rebuttle a lot
