Solana Devs Address Critical Security Vulnerability with Latest Patch as Binance Labs Boosts Restaking

Binance Labs, Binance’s investment arm, has invested an undisclosed amount in Solayer, a new restaking protocol on Solana.
The protocol allows users to restake SOL and liquid stake tokens across Solana-based dApps, strengthening their security and allowing users to maximise yields.
The news coincides with a critical vulnerability found in the Solana network, successfully patched by developers before ending in another outage.
Despite the quick response, SOL’s price has dropped nearly 8% in the day.

Solana projects are in the crosshairs of Binance Labs, as the exchange’s investment arm recently invested in Solayer—a relatively new restaking protocol in which users can restake SOL and liquid stake tokens (LSTs) across several decentralised applications (dApps).

Solayer was launched in late May of this year. The protocol quickly gained popularity in the Solana community, gaining nearly 60K followers on X in under 60 days. By August 9, the project had achieved US$162 million (AU$246 million) in total value locked (TVL), according to data from DefiLlama.

It could be argued that part of Solayer’s popularity is driven by the restaking narrative, which is one of the hottest sectors in the decentralised finance (DeFi) market. Nevertheless, the protocol has a simple yet efficient restaking strategy; in Solayer, you use already staked tokens to secure other dApps on the Solana network (and accrue yields from multiple sources).

Moving on, Solayer pools validator resources across several operators to provide a thick security framework for Solana-based dApps. Interestingly, the project is looking into general asset restaking from AVS (Actively Validated Services) external to Solana, the press release reveals.

The news coincides with a major vulnerability detected in the Solana network, which could have resulted in a major outage. Thankfully, Solana validators, developers, and client teams worked together to patch it before it ended in another disaster.

Laine, a popular Solana validator, publicly disclosed the vulnerability on August 9 only after 70% of the network had successfully implemented the patch. There’s a clear reason for the confidentiality; the patch makes the vulnerability clear so an attacker could try to exploit it and halt the network, Laine said.

Because the patch itself makes the vulnerability clear so an attacked could try reverse engineer the vulnerability and halt the network before a sufficient amount of stake upgraded.

Moving on, Solana Labs issued a statement on Discord, urging the remaining operators to update their systems immediately.

The urgency was underscored by the message that a patched version, v1.18.21, would be available within 30 minutes. Operators were advised to be prepared to upgrade as soon as the announcement was made.

Unfortunately, it hasn’t been good news for SOL, which is down to US$142.28 (AU$217.13), a decline of 7.93% from yesterday.
