Introducing Kiln Connect, the all-in-one SDK for staking on all Proof-of-Stake blockchains

Introducing Kiln Connect, the all-in-one SDK for staking on all Proof-of-Stake blockchains

Over the last three years, as we have been primarily offering validator services, we have observed the challenges that our early customers like Ledger, Bitpanda, and Komainu face when incorporating new staking protocols. These challenges aren't trivial: developing custom transactions, establishing a data infrastructure, and creating custodian API integrations from scratch are both costly and time-consuming. The development costs can range between $100k and $200k for each protocol, with the added necessity to maintain and scale these protocols over time.

Understanding these challenges and staying true to Kiln's core value of putting our customers first, we present Kiln Connect: the all-in-one SDK for staking on all Proof-of-Stake blockchains. Developed in collaboration with the product teams of prominent exchanges and custodians, our software team has designed the SDK initially to simplify staking integration.

Kiln Connect offers a unified API for crafting staking and unstaking transactions and a comprehensive reporting API covering all major protocols. This abstracts the complexities in staking integration, making it both seamless and painless.

Key advantages of Kiln Connect for staking integrators

By using Kiln Connect, businesses can efficiently go to market for staking without the need to build products and tools in-house, which saves both time and cost. Additionally, they can benefit from enterprise-grade staking capabilities through simple API calls with continuous integration of new protocols and support.

Moreover, Kiln Connect is validator agnostic, which means it supports not just Kiln-managed validators but any node operator. Institutional companies find this feature invaluable as it allows them to manage several node operators and validators through a single API. This eliminates the problem of asymmetrical and scattered data across different providers.

Reporting API: Unify & automate your reporting across all providers

Kiln Connect Reporting API offers real-time data monitoring, including balances, rewards and validator performance, catering to both platform operators and their end-users. Its robust reporting capability stands out as it doesn’t merely collect and display data; it automates accounting & compliance. By doing so, it significantly reduces the chances of manual errors, ensuring that the data's integrity remains uncompromised.

Top 3 reasons to opt for Kiln Connect Reporting API:

1. Comprehensive data indexing: In the staking ecosystem, diversity is the key. With a multitude of protocols and node operators, having a tool that can seamlessly index staking data across all of them is extremely useful. Kiln Connect Reporting API does that precisely, providing users with all the relevant data at their fingertips.

2. Real-time, investor-grade data: The API provides real-time, investor-grade data that enhances the staking experience in your app. Users can make informed decisions backed by current, accurate and reliable data. The quality of data provided makes it certain that users are always a step ahead, equipped with insights that empower them to make strategic decisions.

3. Production-ready APIs with SLAs: In the fast-paced world of digital assets, waiting weeks or even days for API integrations can be a deal-breaker. Kiln understands this urgency and equips users with production-ready APIs. What's more, with Service Level Agreements (SLAs) in place, users are guaranteed top-tier reporting, ensuring consistent performance and reliability.
