Dear ETHDenver hackers,

After ETHSanFrancisco, ETHSingapore and Devcon4, Celer Network is thrilled to meet everyone at ETHDenver in a few weeks!


Are you looking to build highly interactive Ethereum games, online auctions, prediction markets or micro payment services, but frustrated by the long transaction confirmation and the high transaction fees? If so, we invite you to build millisecond-latency, zero-fee and highly interactive off-chain dApps with Celer SDK! Try out our example applications and see what you can build on Celer here.

What is Celer?

Celer Network is a leading layer 2 scaling platform that enables fast, easy and secure off-chain transactions for not only payment transactions, but also generalized off-chain smart contract. It enables everyone to quickly build, operate, and use highly scalable decentralized applications through innovations in off-chain scaling techniques and incentive-aligned cryptoeconomics.

What can you build on Celer?

Our cWallet application with a connect-five board game and instant payment is entirely built based on Celer SDK and you can also build your game on Celer as well!!
