The best all-in-one SDK for staking
on all PoS chains

Request a demo

Today, integrating new protocols for staking requires building custom staking / unstaking transactions for each individual protocol format, running data rewards collection infrastructure, and integrating custom custodian APIs. All these tasks take precious engineering time and involve expenses which are better spent on more strategic initiatives.

How does Kiln Connect solve these issues?

Transaction crafting API

One simple universal interface for staking/unstaking transactions on all PoS chains.

Rewards API

A unified rewards API used on all PoS chains.

Custodian API

One common interface to sign staking transactions on every protocol for all supported custodians.

Admin Dashboard

View, track and pilot all stakes in real-time.

How does it work?


This is what a custom staking transaction looks like to stake ATOM without Kiln Connect


Going through Kiln Connect the staking transaction is standardized for all protocols, becoming a single line of code


Validators are programmatically deployed and start earning rewards


The validators accumulate rewards, Kiln Connect logs the rewards/commission data for partner & end-users


Staking rewards data is collected for each user. Rewards and commissions flow to the users and Kiln partner custody solutions

Integrate protocols faster to offer staking on all PoS networks
