What Mellow does
Mellow operates modular onchain vault infrastructure for institutional asset management, anchored by its Core Vaults architecture and verifier model. The platform encodes strategy constraints onchain with 60+ granular permissions, subvault isolation, oracle guardrails, emergency safeguards, and role-based access control, enabling new allocation strategies to be deployed in hours without custom smart contract engineering. The product portfolio spans Core Vaults, DVstETH (a DVT-incentivized wrapper around Lido wstETH integrated with Obol and SSV), the stRATEGY vault, a suite of restaking vaults (MultiVault, Interoperable Vaults via LayerZero, Simple LRT), the Mellow ALM active liquidity management system, a public REST API, an agent-ready CLI, and a Points loyalty program.
Mellow sells to crypto-native and TradFi fintechs, neobanks, exchanges, wallets, custodians, and asset issuers under an API-first B2B enterprise model. Partners integrate via REST endpoints and ship branded yield, treasury, and managed-yield products under their own UX, with Mellow infrastructure underneath. The go-to-market combines API-first integration for fintech partners with direct enterprise field sales supported by a self-serve app for depositors and curators. Named partners include Lido, Symbiotic, Ethena, Flow Traders, Keyrock, Obol, Chorus One, SSV Network, and Zircuit, with 50+ partners and 60+ active vaults reported and peak Total Value Locked reaching $1B. The revenue stream is vault infrastructure fees earned from partner deployments under multi-year enterprise contracts; pricing is not publicly disclosed.
The company is headquartered in the United States (Virgin) and was founded in 2022. Security posture is reinforced by independent audits from OpenZeppelin, ChainSecurity, Decurity, Statemind, Nethermind, Sherlock, MixBytes, and Locklogo. Headcount is 11-50 and the company has raised a single disclosed seed round of $2.75M in 2021 led by Arrington Capital, ParaFi Capital, and Robot Ventures, with no subsequent priced round identified in the source data.

Mellow product offering
Product offeringCore offering
Mellow provides modular onchain vault infrastructure for deploying curated yield products with explicit risk boundaries and predictable execution surfaces. Its Core Vaults architecture enables fintechs, exchanges, and asset issuers to launch Earn, treasury, and managed yield programs via API-first integration, without requiring DeFi or smart contract expertise. The platform supports liquid staking, restaking, and active liquidity management through a portfolio of vault products including DVstETH, stRATEGY, MultiVault, and Mellow ALM.
Product overview

Products and services
- Core Vaults Mellow's primary vault architecture for deploying curated onchain structured products with explicit risk boundaries, predictable execution surfaces, and stable interfaces. Encodes strategy constraints onchain including which integrations can be used, permitted actions, and capital movement rules.
- DVstETH (Decentralized Validator Vault) Wrapped liquid staking token powered by Lido wstETH with DVT (Distributed Validator Technology) incentive layer. Integrates with Obol and SSV for validator incentives. Users deposit wstETH and receive DVstETH tokens.
- stRATEGY Vault Strategy vault accepting ETH, WETH, and wstETH deposits with withdrawals to wstETH. Features fee structure and strETH token mechanics for yield strategy management.
- MultiVault Restaking vault that aggregates multiple isolated subvaults into a single user-facing vault with ERC4626 extension, configurable limits, whitelists, and locks.
- Interoperable Vaults Cross-chain vault model where users deposit on EVM L2s and receive shares, with restaking executed on Ethereum mainnet via LayerZero OFT messaging.
- Simple LRT ERC4626-modified vault with queued withdrawals via SymbioticWithdrawalQueue. Built around MellowSymbioticVault or MellowVaultCompat for liquid restaking token flows.
- Mellow ALM (Active Liquidity Management) Permissionless multi-ERC20 vaults with three actor roles (liquidity provider, strategist, governance) for DeFi liquidity management across protocols and chains. Includes Fearless Gearbox strategy, Pulse strategy, Tamper strategy, and Uni V3 Boosted strategy.

Mellow competitors and assessment
Company assessmentDirect peers
- Morpho: Morpho is a DeFi lending and yield infrastructure protocol enabling optimized lending markets. Both Morpho and Mellow operate as B2B yield infrastructure for fintechs and protocols, providing curated onchain strategies with programmable risk constraints.
- EigenLayer: EigenLayer is the leading restaking protocol that Mellow's products integrate with and rely on. Both operate in the same restaking/yield ecosystem, with EigenLayer building similar restaking primitives natively that could compete with Mellow's vaults.
- Symbiotic: Symbiotic is a restaking middleware protocol and one of Mellow's core integration partners. Both offer modular restaking and yield infrastructure, and Mellow's Simple LRT vault is built directly on Symbiotic withdrawal queues.
- Pendle: Pendle is a yield tokenization protocol that Mellow's ALM integrates with for principal and yield token trading. Both operate yield-strategy infrastructure for DeFi, with overlapping user bases seeking structured yield exposure.
- Enzyme (formerly Melon): Enzyme is on-chain asset management infrastructure enabling anyone to deploy and manage crypto investment vehicles. Both Mellow and Enzyme provide modular infrastructure for onchain structured products with explicit risk boundaries.
Broad incumbents
- Convex Finance: Convex is an established yield-optimization and infrastructure layer originally built on Curve. Both Convex and Mellow provide vault infrastructure that abstracts complex DeFi strategies behind a simpler interface for users and partners.
- Yearn Finance: Yearn is one of the original DeFi yield aggregators, automating yield strategies across protocols. Both Mellow and Yearn offer automated yield strategies housed in vault contracts, though Mellow focuses more on B2B/enterprise distribution.
- Beefy Finance: Beefy is a multi-chain yield optimizer with auto-compounding vaults across many protocols. Both operate strategy vaults that automate yield generation, though Beefy is primarily retail-focused while Mellow is enterprise-focused.
Emerging players
- Karak Network: Karak is a restaking platform competing in the same modular restaking space as Mellow's MultiVault and Simple LRT. Both target similar use cases around secure restaking infrastructure with risk controls.
- Babylon Labs: Babylon is building Bitcoin staking infrastructure extending yield opportunities into the BTC ecosystem. Both operate staking/restaking infrastructure targeting institutional and partner integrations with similar security-focused design philosophies.
