What is the Transaction Crafting API?

The Kiln Transaction Crafting API enables you to craft staking and unstaking transactions from all major PoS protocols using a single, unified API which supports all validator providers. This enables you to speed up the delivery of your staking product across several chains. 

The API also includes a bridge to your custodian, so that you can continue to sign transactions where your assets are secured.  

The API is RESTful enabling you to query it from the language of your choice, we also provide JS and Python SDKs for convenience.

Why should you implement it?

Speed up your staking offering

Save valuable time and resources by using Kiln’s API to integrate staking on all major chains, without having to develop custom integrations with each.

Sign transactions through your custodian

Transactions crafted through the API can be sent to your custodian for signing, so you maintain your existing custodian for securing your assets.

Provide multi-protocol coverage

Users expect to be able to stake all assets from the same interface. The API supports all major PoS assets, enabling you to build confidently on top of it.

Compatible with all major PoS blockchains

How does it work?

1

Crafting a staking tx manually requires interfacing with each protocol’s transaction formats.

2

Crafting the tx using the Transaction Crafting API can be done in a single call, which is unified across all chains.

3

If using Kiln validators, validators are programmatically deployed and start earning rewards.

4

The validators accumulate rewards, the Reporting API logs the rewards/commission data for partner & end-users.

5

Staking rewards data is collected for each user. Rewards and commissions flows to the users.

REMINDER

Kiln Reporting API

Kiln Connect is not limited to just a Transaction Crafting API; it also includes the most advanced Reporting API in the market. The Reporting API empowers exchanges, custodians and market makers by providing standardized data for their users' stakes across major protocols and multiple staking operators in an unified way.

FAQ

What is the main difference between on and off-chain?

"OnChain" operations are executed directly within a blockchain network, ensuring transparency and verifiability, whilst eliminating the dependence on centralized entities. In contrast, "off-chain" operations refer to processes conducted outside the blockchain network and involve the participation of third parties that lack the same level of open transparency.

What protocols are supported through Kiln On-Chain?

Ethereum is the first protocol to be supported.

How many Kiln products are on chain?

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:

For institutions:

Dedicated Validators: Native ETH protocol staking in batches of 32 ETH, providing a dedicated and secure staking solution.
Validator NFT: Same as ‘Dedicated Validators’, but with the ability to generate an NFT that represents ownership and withdrawal credentials of the validator.

For exchanges and wallets:

Kiln Pooling: Enables integrators to offer services that allow staking any amount of ETH in exchange for an individualized part of the staking pool.
Kiln Liquid Staking Pool: Same as ‘Kiln Pooling’, but with the ability to generate a transferrable token that represents the withdrawal credentials and the ownership of the individualized part.

What are the main advantages of Kiln On-Chain?

Kiln On-Chain empowers integrators to establish Ethereum staking solutions, for holdings of 32 ETH or less, while also providing optional transferability capabilities.

Integrators gain the advantage of earning recurring revenue through automated rewards dispatch. Furthermore, the user experience is seamless with a deposit transaction that allows users to easily engage in staking.
