Cactus Custody now supports Lido V3 stVaults, giving institutional investors a way to hold Ethereum staking positions through a regulated custody provider. The integration, announced this week, enhances institutional access to liquid staking on Ethereum — a step that could boost adoption while balancing customization with the risks that come with it.
What the integration does
Lido's V3 stVaults are customizable staking pools that let users tailor their risk exposure. By adding custody support, Cactus Custody allows institutional clients to hold those positions without managing private keys themselves. The move means asset managers, endowments, and other large holders can now include liquid staking in their portfolios through a familiar custody framework.
Why custody matters for staking
For institutions, custody is often the gatekeeper. Without a qualified custodian, many funds and asset managers simply can't touch staking. Cactus Custody's support for Lido V3 stVaults removes that barrier, potentially funneling more capital into Ethereum staking. The firm didn't disclose which clients are using the service, but the timing puts it ahead of some competitors still building out staking custody.
The risk factor
The integration doesn't eliminate risk. Lido's stVaults allow customization of parameters, but that flexibility can introduce complexities — slashing risk, smart contract risk, and market risk. Cactus Custody's role is to secure the asset, not to manage the strategy. Institutions that use the service still need to understand the underlying mechanics of liquid staking, including how rewards and penalties flow through.
The integration is live as of this week. Whether it moves the needle on institutional ETH staking will depend on how many clients take up the option. For now, it's one more bridge between traditional custody and the on-chain staking economy.
