Kiln

Kiln is a Paris-based enterprise staking and onchain asset management platform that operates institutional-grade validator infrastructure across more than 30 proof-of-stake blockchains. Founded in 2018, the company functions as the infrastructure layer enabling custodians, asset managers, exchanges, and fintech applications to offer staking yield to their clients without building or managing the underlying validator operations themselves.

The platform has accumulated more than $18 billion in total delegated assets since launch and has generated over $800 million in staking yield for clients. Kiln holds SOC 2 Type II certification—renewed in June 2026—and runs on a multi-cloud, multi-region architecture designed to satisfy the compliance and uptime requirements of regulated financial institutions.

Enterprise-First Architecture

Kiln's product suite is built around programmatic access to staking rather than retail-facing applications. The Connect SDK provides a unified API layer that abstracts away validator operations, rewards tracking, and protocol-specific complexity across all supported networks. A Reporting API and Transaction Crafting API add enterprise tooling for automated accounting, tax reporting, and transaction construction.

For organizations that want to embed staking directly inside their existing products, Kiln offers a no-code Widget and white-labeled staking pool infrastructure. An Enterprise Dashboard gives institutions a consolidated view of delegated assets, pending rewards, and validator performance across every network from a single interface.

Notable institutional clients include Fireblocks, Ledger Enterprise, BitGo, Binance US, Bitpanda, VanEck, Lido, Trust Wallet, Komainu, CoinShares, Crypto.com, MetaMask Institutional, and Uphold. Ledger Live, Crypto.com, and Coinbase have specifically relied on Kiln's pooled staking infrastructure to enable ETH staking for their own users, embedding Kiln's technology behind their branded interfaces rather than building validator operations independently.

Solana Infrastructure

On Solana, Kiln operates validator infrastructure with approximately $617 million in delegated SOL as of August 2026, representing roughly 1.6% of all staked Solana. Its validators maintain a stake-weighted skip rate of 0.13% compared to a 0.24% network average, and a voting effectiveness of 99.6% against the 99.5% network standard. The platform supports a minimum stake of 0.01 SOL and a current gross reward rate in the 6–7% range, with rewards compounding automatically each epoch.

Kiln offers Solana staking through its Connect API and through white-label arrangements where institutional partners embed SOL staking into their own platforms. The architecture is non-custodial: client assets are delegated to Kiln's validators rather than transferred, with unstaking subject to standard protocol cooldown periods.

In August 2026, Abra selected Kiln to power Solana staking for its institutional and private client base, integrating Kiln's validator infrastructure and position-level reporting directly into Abra's wealth management platform. The partnership reflects Kiln's consistent strategy of embedding its infrastructure behind financial platforms rather than competing directly for end-user relationships.

Recent Developments

Kiln joined Lido's v3 upgrade as a sanctioned node operator in February 2026, integrating into one of Ethereum's largest liquid staking protocols and expanding the addressable use cases for its validator fleet beyond direct delegations.

In June 2026, Kiln added AI-agent integration to its Connect platform by publishing an MCP Server and llms.txt file that allow autonomous agents to query staking positions, request rewards data, and initiate transactions through the API without per-call human configuration—an infrastructure capability aimed at institutional treasury and yield management workflows increasingly being automated by AI agents.

Kiln is also building Railnet, an open yield layer announced at Vault Summit in November 2025. Railnet enables institutions to compose DeFi yield strategies across Kiln's supported protocols—including lending protocols such as Aave, Morpho, Compound, and Spark—using the same API surface as its staking infrastructure. In July 2026, Uphold added Kiln to power staking rewards for its users, beginning with the XDC network.

Beyond Ethereum and Solana, Kiln has built out Bitcoin staking support as institutions have sought yield on BTC holdings, alongside continued coverage of Cosmos, Cardano, Avalanche, Near, Tezos, Tron, Aptos, and more than 20 additional networks.

Funding

Kiln has raised approximately $35 million across two institutional rounds. A $17.6 million raise in late 2022 was followed by a $17 million Series A in January 2024 led by 1kx, with participation from Crypto.com, IOSG Ventures, Wintermute Ventures, KXVC, and LBank, alongside returning investors Kraken Ventures, GSR, and Avon Ventures. The company is co-founded by Laszlo Szabo and Ernest Oppetit and maintains open-source validator monitoring tooling for Ethereum, Cosmos, Near, and Cardano as part of its ecosystem contributions.
