Stake from Copper

Kiln is a non-custodial staking provider. As a customer and owner of your assets, it is YOUR responsibility to check and verify all the transactions you are signing. While Kiln provides tooling to help you interact with your stakes (web applications, APIs), Kiln is not responsible for the transactions that you sign.

The below list includes only protocols that are supported both by Copper and Kiln
