Casa, a self-custody platform for Bitcoin, has added support for Ethereum storage with multi-signature security. Previously, Casa provided self-custody solutions for Bitcoin only, allowing users to store their cryptocurrency using up to five keys for distributed security. With the addition of Ethereum support, ETH holders can also use up to five keys to secure their holdings. Casa is engaging with users on the potential of adding self-custody support for various ETH-related assets such as non-fungible tokens (NFTs), stablecoins, and ERC-20 tokens. The move comes after increasing calls from Casa’s users and the wider crypto community for a multi-signature ETH self-custody following high profile collapses of major exchanges like FTX. According to Casa CEO Nick Neuman, many users not only lost access to ETH but also their Ethereum-based stablecoins and other ERC tokens due to poor private key management.
