Interoperability

• From EthHub (27-7-2021):

"Celer cBridge v1.0 is now live on mainnet! Users are now able to use cBridge to instantly transfer tokens across Ethereum, Arbitrum and Polygon with many more side chain and layer-2 chain integrations planned for in the near future."

• From their blog (3-8-2021):

"Within the first week of launch, Celer’s cBridge helped 600+ users bridging 1000+ cross-chain assets transfer with a $2.5M in total volume, while saving users more than $90K in total gas costs."

Sidechain L2

• From their announcement of their Hybrid Rollup (20-7-2020):

"The Celer Sidechain adopts a hybrid architecture offering sidechain security via a Delegated Proof of Stake (DPoS) consensus for general dApps and mainchain security via optimistic rollup for specific usages such as token transfers. As a part of the Celer Coherent Layer-2 Platform, the rollup sidechain shares the same validator set with the state guardian network. The rollup sidechain validators and SGN validators will be elected and governed by the same layer-1 DPoS contract for staking, rewarding, and slashing."

Layer2.finance

• From EthHub (27-4-2021):

"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”."

• From the Celer blog (22-4-2021):

"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. Enabled by a unified strategy abstraction, Layer2.finance’s community-built and community-hosted “turn-key” UI provides a simple one-stop-shop experience for users to navigate the increasingly complex DeFi landscape."
