Kchannels

A payment channel system for Ethereum with great UX and fast finality

Layer2 FOR THE PEOPLE

Kchannels is a new payment channel platform for the Ethereum blockchain. It is non-custodial and trust-minimized, and its primary focus is on great UX and instant off-chain finality. Among other things, it is well suited for commerce use-cases (e.g. merchants and their customers).


Kchannels is available on Mainnet (and testnets) *today* with support for Ether and ERC-20 tokens.

Multi-Channels: A new channel construction

Kchannels utilizes a powerful new channel construction called a multi-channel. A multi-channel enables you to transact with anyone both within Kchannels and on the blockchain, and it also stores multiple assets in one place, so it can act as a lightweight hot wallet. You can also open as many as you want, but most people would really only need one for all their needs.

A channel can hold multiple assets, and it can send and receive multiple assets in a single transaction.

An unattended channel can still receive transactions, and all funds within it are safe. No need to watch the blockchain!

Deposits and withdrawals to/from Layer1 are fast and easy--no additional waiting beyond the time it takes to mine a block.

Most users only need a single channel--ever--for all their needs! A channel is free to create, and it only takes an instant.

FAST FINALITY

Finality on Layer2 is hard; many Layer2 solutions can't guarantee that your transaction is confirmed and final for a long time after it seemingly completes. Others achieve finality by imposing significant requirements on their users, such as the need to monitor the blockchain at all times until the final on-chain settlement. In Kchannels a Layer2 transaction is truly final and confirmed as soon as it completes--instant off-chain finality for a very credit card-like experience--without imposing any additional burdens on the user.

Fast finality is an absolute necessity for many important use-cases that are currently not supported by the Ethereum ecosystem.

DESIGNED from the GROUND UP for great UX

Imagine transacting in Web3 with the UX of Web2. Transact in Layer2 as if you were hitting the Stripe API; you make a simple call and you're done.

minimal infrastructure requirements

No need to install any software, not even Geth.

no special token

There is no special token anywhere in the system.

NO NETWORK

Kchannels avoids all the complexity of routing transactions through a public Layer2 network.

no CHANNEL BALANCING

Transactions are not bottlenecked by the need for funds elsewhere in the system; your transaction is always delivered with no intermediaries.

high scalability

Kchannels can scale horizontally to support any throughput desired simply by adding additional hardware.

CHANNELS ARE FREE

Channels are fast and free to open as they do not require transactions on Layer1. They also do not need to be funded to stay open.

...AND EVERYTHING ELSE YOU EXPECT FROM A PAYMENT CHANNEL SOLUTION

FAST TRANSACTIONS

No more waiting for blocks/confirmations; no more dealing with congestion.

LOW FEES

No more dealing with expensive and ever-changing gas prices.

PRIVACY

In-channel transactions are not visible on-chain.
