Stake your assets with Kiln

Deploy Kiln's white-label solutions

Explore Kiln's featured integration use-cases

Kiln is a staking platform you can use to stake directly, or whitelabel staking into your product.

We enable you or your clients to stake crypto assets, manually or programmatically, while maintaining custody of your funds in your existing solution, such Fireblocks, Copper, or Ledger.

In these docs, we will take you through how to do all that.

Happy integration, and don't hesitate to reach out to us if you have any questions!

Protocols

We are shutting down some protocols as part of a broader effort to streamline our focus and deliver more value to our customers. This means simplifying our offering and tightening our listing criteria to prioritize higher-revenue chains, and focusing on those with the strongest customer demand. Due to this we will cease running the supported validators early in 2026.

We will continually update this document with decommission dates as we progress through through the shutdown process.

A new consolidation feature will let you convert skimming validators to compounding validators and merge them into target compounding validators. These consolidation requests are sent from the execution layer to a special smart contract with fee mechanisms to prevent DDoS attacks. To consolidate validators, you must control the withdrawal credentials of the source validators, and only compounding validators can be targets. There is one exception: when converting a single skimming validator to a compounding validator, you can send a consolidation request using the same validator as both source and target.

Rewards earned on DYDX are DYDX-USDC. In this tutorial we will present how to bridge these rewards to Ethereum or to Osmosis using the Kiln SDK. These flows can be done directly from Kiln Dashboard if you are using Fireblocks.

Bridge to Ethereum

The goal of this bridge is to bring your dYdX rewards in USDC on your ETH address so that you can use them for other purposes like depositing them on a centralized exchange to get some dYdX back.

To convert your DYDX-USDC to USDC on Ethereum, we will use the Noble bridge developed by Circle, which is the recommended on-chain approach.

There is 3 steps to this flow:

1) Transfer the USDC from DYDX to the Noble chain

2) Burn the USDC on Noble

3) Mint the USDC on Ethereum

Here is a TypeScript code snippet that you can use:

Bridge to Osmosis

The goal of this bridge is to bring your dYdX rewards in USDC on another cosmos address here on Osmosis so that you can use them for other purposes like depositing them on a centralized exchange or a Swap on Osmosis to get some dYdX back.

This flow follows two steps:

1) Transfer the DYDX-USDC to the Noble chain

2) Transfer the USDC on Noble to Osmosis
