About Attestant
Attestant is an institutional-grade Ethereum staking provider offering non-custodial staking services. Its core business allows clients to stake ETH while retaining full control of their assets, as Attestant never holds withdrawal keys. The company addresses the market pain point of institutional investors who require high security, operational reliability, and compliance reporting but lack the technical infrastructure to run validators themselves. Attestant's competitive edge lies in its multi-layered security architecture, including distributed validator technology and redundant client setups, which minimizes downtime and slashing risks.
