This newsletter is made possible thanks to Celer!

Celer recently launched Layer2.finance on Ethereum mainnet.

Layer2.finance tackles the two biggest challenges preventing DeFi from reaching mass adoption: the extraordinarily high transaction fees and being very difficult to navigate and use. Layer2.finance is a novel solution that allows people to access all existing DeFi protocols at a fraction of the cost by acting like a “DeFi Public Transportation System”. With Celer’s advanced layer-2 rollup technology, multiple people split the cost of individual layer1DeFi transactions in a completely trust-free and non-custodial way.

Users can use Aave, Compound and Curve now completely for free via layer2.finance.

Follow Celer on twitter, blog, discord and telegram.
