The problems addressed by Kiln On-Chain

  1. Offering non-custodial ETH staking is hard, as Ethereum lacks an on-chain commission system, platforms adopt two approaches: they either hold staked ETH or rewards to earn commissions, or they charge deposit fees rather than relying on staking rewards as an incentive.

  2. Existing ETH offerings can be opaque as the complete fund flow, including deposit handling, reward management, and commission distribution, isn't solely managed through transparent smart contract logic.

  3. Introducing new use-cases on a validator infrastructure, like solo staking, pooled staking, or validator NFTs, is challenging due to the absence of established standards for operators in these areas.

  4. Create a custom staking offering for your platform, customizing commissions from staking rewards, distributing them to partners, seamlessly integrating multiple operators, and even issuing Liquid Staking Tokens like NFTs or ERC20 tokens to represent users' staked positions.

Kiln On-Chain is an audited suite of smart contracts that eliminates these barriers, enabling integrators to offer fully branded, customisable, non-custodial Ethereum staking to end-users, while earning a revenue share. With Kiln On-Chain, integrators can now prioritise user retention and earning a rewards share from offering seamless Ethereum staking.

Introducing Kiln On-Chain platform

Kiln On-Chain addresses three main actors:

  1. Integrators, such as wallets or exchanges, that want to create a custom staking solutions for their users. This may involve solo staking with one operator or proposing their own Liquid Staking Token with 2 operators.

  2. Operators are Ethereum validator providers who integrate their validator infrastructure via smart contracts, enabling them to offer staking services like pooling or dedicated staking, and accept deposits from multiple Integrators.

  3. Stakers are ETH holders seeking to engage in Ethereum protocol staking, and they can choose between pooled solutions or dedicated staking. Throughout the entire staking process, they retain custody of their assets, ensuring a fully transparent and auditable fund flow.

Kiln On-Chain offers a suite of smart contracts designed to allow integrators to accommodate a wide range of use cases within native and pooled staking. Currently, there are four distinct options available:

  1. Dedicated Validators: Native ETH protocol staking in batches of 32 ETH, providing a dedicated and secure staking solution.

  2. Validator NFT: Same as β€˜Dedicated Validators’, but with the ability to generate an NFT that represents ownership and withdrawal credentials of the validator.

  3. Kiln Staking Pool: Enables integrators to offer services that allow staking any amount of ETH, without the issuance of a transferrable receipt token.

  4. Kiln Liquid Staking Pool: Same as Kiln Staking Pooling but with the ability to issue a custom transferrable receipt token that represents the withdrawal credentials and the ownership of the users stake.


There are multiple ways Integrators can propose staking to their users (Stakers) through the On-Chain platform (pooled, dedicated, ...), but the underlying principles remain the same across all the components of this product:

  1. Transparency: deposits, commissions dispatching or exits, everything happens on-chain and is easy to track via Event emissions and simple view functions everyone can call.

  2. Security: staking through this audited solution is designed to be non-custodial (* some parts will be upgradable for a certain timeframe), and a lot of on-chain and off-chain safety guards are in place to protect users funds and rewards.

  3. Flexibility: integrators have the choice between multiple staking integration types and can create their custom offering with or without liquidity tokens, or with one or multiple operators.
