Layer-2 Blast Ends Partnership With Safe Over Third-Party Risks, Prepares to Launch Own Multi-Signature Solution
Blast, a Layer-2 platform built by Blur founder Pacman and backed by Paradigm, has officially announced the end of its partnership with Safe (formerly Gnosis Safe), one of the leading multi-signature wallet providers in the Ethereum ecosystem.
In a statement posted on X (Twitter) on May 13, the Blast development team said that they “will not renew” their service agreement with Safe, warning of supply chain risks and limited usability from third parties. The decision comes as Blast is in the process of developing a multi-signature solution that integrates directly into its own mobile app, Blast Mobile.
“We want to ensure that users can access their wallets securely and seamlessly – without relying on third parties,” the development team emphasized.
“That’s why we’re integrating multi-sig functionality directly into Blast Mobile – bringing security and convenience to the entire Blast community.”
Users have two options: BrahmaFi or independent hosting
Since ending support for Safe, users who have used Safe’s UI to manage their multi-sig wallets on Blast now have two alternatives:
Switch to BrahmaFi – which supports a multi-sig interface specifically for the Blast ecosystem.
Self-host the UI – a way to mitigate risks from supply chain or third-party software vulnerabilities.
The fallout from Safe’s restructuring and security controversy
The decision to end the partnership comes just weeks after Safe announced a major restructuring, including the layoff of 14 employees. Safe co-founder Lukas Schor said the company was forced to “say goodbye to great teammates” due to growing internal complexity, which was affecting the speed of product development.
Notably, this restructuring phase comes shortly after a serious incident involving a security vulnerability exploited in the development environment related to Safe. The attack cost the Bybit exchange $1.43 billion, allegedly by a North Korean-linked hacker group (TraderTraitor). The group used emulator software to install malware and hijack session tokens from developers’ laptops.
Conclusion
Blast’s discontinuation of Safe integration is a sign of growing awareness of external risks in the blockchain ecosystem, especially as Layer-2 platforms begin to expand into the consumer market. Integrating a native multi-signature solution not only provides better security control, but also affirms the in-house development orientation and reduces third-party dependence of modern Web3 projects.
