This newsletter is made possible thanks to Celer’s layer2.finance!


Celer is a coherent layer-2 scaling platform on Ethereum powered by Generalized State Channel Network and Rollup technology. 

Celer recently launched Layer2.finance, a layer-2 rollup-based DeFi aggregator that acts as a low-cost and trust-free gateway for the users to explore and benefit from the existing DeFi ecosystem with 100X lower cost. Layer2.finance achieves scalability “in-place” with no protocol migration needed and therefore, does not cause liquidity fragmentation or break composability. You can use the app here: app.l2.finance

Follow Celer on twitter, blog, discord and telegram.
