What is Kiln?
Kiln is an institutional digital asset staking and rewards infrastructure platform operating multi-cloud validators across more than 30 Proof-of-Stake blockchains. The platform allows institutions, custodians, and fintechs to offer native staking, liquid staking, and DeFi yield through APIs and dedicated validators.
Team and corporate history
Founded in 2018, Kiln is headquartered in Paris, France. The platform was created by Chief Executive Officer Laszlo Szabo, previously a co-founder of recruitment firm Skill Hunter; Chief Operating Officer Thomas de Phuoc, formerly Country Lead for France at Circle; and Chief Product Officer Ernest Oppetit. The company has raised $35 million in venture capital, including a $5 million round in May 2022 with participation from ConsenSys and Kraken, and a $17 million Series A round in January 2024 led by 1kx to fund international expansion.
Staking architecture and integration
Kiln operates an enterprise architecture designed around a bring-your-own-custodian model, integrating natively with custody providers like Fireblocks, Copper, and Ledger. This setup ensures that institutions retain full custody of private keys while delegating stakes. The platform supports native and dedicated staking on networks such as Ethereum, Solana, Aptos, Avalanche, Cosmos, Cardano, NEAR, and Sui. Kiln also offers pooled staking options, such as single-nominator and pooled contracts on The Open Network (GRAM) with a 10 TON minimum stake. Beyond direct staking, the Kiln Connect API and Kiln Widget allow platforms to embed staking and DeFi lending strategies across more than 12 protocols into existing user wallets.
Security and operating track record
Kiln holds an active SOC 2 Type II compliance certification audited by Insight Assurance, which was renewed with zero exceptions in June 2026. The platform also contributed infrastructure to the Liquid Collective enterprise liquid staking standard, with smart contracts audited by Halborn. The team has expanded support across multiple networks, deploying Canton Network co-validation in September 2026 and introducing HYPE staking via the Fireblocks console in October 2026.
Risks and considerations
Staking through Kiln exposes capital to traditional network-level slashing rules, unbonding delays, and protocol downtime penalties. While institutional users retain private keys, deploying through pooled smart contracts or DeFi lending vaults introduces smart contract and protocol layering risks. Kiln experienced an infrastructure incident requiring a coordinated validator exit, though user funds were kept protected.

- Experienced a past infrastructure issue that prompted an emergency validator exit
Our review
3.8/5
Good
Kiln delivers enterprise-grade multi-chain staking infrastructure and compliance reporting, but its enterprise-focused model offers less utility for retail stakers wanting liquid, highly composable DeFi tokens.
Kiln is an institutional staking and developer infrastructure platform founded in 2018 in Paris, France, by Laszlo Szabo and Thomas de Phuoc. The platform enables custodians, exchanges, asset managers, and retail wallets to deploy validators across more than 30 Proof-of-Stake networks, including Ethereum, Solana, Cosmos, Aptos, Cardano, and Near. Kiln provides dedicated validators and API tooling for partners such as Fireblocks and Ledger.
Security and institutional custody are central to Kiln's architecture. Stakers retain asset custody through integrations with platforms like Fireblocks and Copper. The company renewed its SOC 2 Type II certification with Insight Assurance in June 2026 and underwent smart contract audits with Halborn for its liquid staking developments. Kiln also operates on a multi-cloud, multi-client setup. While Kiln resolved an earlier infrastructure issue by initiating a validator exit to protect user funds, delegating through institutional validators still carries base slashing and client uptime dependencies.
Asset support spans native PoS delegation, Ethereum pooling contracts, and restaking workflows via protocols like EigenLayer and Babylon. On Ethereum, Kiln accommodates dedicated 32 ETH validators alongside pooled fractional staking. Reward rates reflect native network yields, such as 2.6% on Ethereum and 6.5% on Solana as of October 2026. Kiln offers liquid staking through frameworks such as Liquid Collective.
Kiln suits institutions and fintechs seeking non-custodial validator infrastructure with programmatic APIs and audit trails.

Institutions are moving trillions of dollars onchain, but yield infrastructure is still fragmented, manual and hard to scale for regulated players.
Today we are introducing Railnet, an open yield infrastructure that standardizes how capital moves across staking, DeFi, tokenized assets, and real world yield.
Rather than competing for deposits, Railnet acts as neutral infrastructure connecting asset managers, protocols, and platforms on shared rails, with:
• Cross protocol strategy composition
• Compliance controls and address whitelisting
• Asynchronous execution (KYC and delayed settlement)
• Unified reporting across onchain and tokenized markets
