Supporting Institutional-Sized Deposits

Twinstake clients can stake in batches of 100 validators, allowing them to make institutionally sized validator activations in an efficient manner.

Ethereum’s Pectra upgrade introduces new flexibility by allowing validator deposits to range from 1 to1 and 2048 ETH. To ensure institutional clients can seamlessly adapt, Twinstake’s batch deposit contract supports this expanded range and enables multiple batch configurations in a single transaction. Instead of submitting hundreds of uniform deposits, clients can now structure deposits to match treasury and operational needs - for example, 50 deposits of 100 ETH, 150 deposits of 400 ETH, and 50 deposits of 900 ETH - all in one streamlined process.

Built in Collaboration, Audited for Security

This product was developed in close collaboration with Nethermind, leveraging their deep Ethereum expertise, and underwent a comprehensive audit by Quantstamp to ensure robust security and reliability. By building this functionality in-house, Twinstake is no longer reliant on third-party modifications.

Our collaboration with Twinstake addresses real challenges faced by institutional investors by harnessing the new features of Ethereum’s Pectra upgrade. By contributing our protocol expertise, we helped design a batch deposit solution that is both operationally efficient and secure at scale. Twinstake’s decision to open source this contract not only strengthens staking infrastructure but also reinforces Ethereum’s role as the foundational network of the global digital economy.

Open Source Contribution to the Ecosystem

Recognising that batch deposits are a key challenge for institutions entering staking at scale, we are open-sourcing the contract as a contribution to the Ethereum community. By doing so, we aim to lower barriers for institutional adoption, while ensuring transparency and encouraging ecosystem-wide improvements in staking infrastructure.

The batch deposit contract is now live and available via the Twinstake API at the following endpoint:
