Shido

Shido is a blockchain‑based organisation that maintains an Ethereum layer‑2 network designed to improve transaction throughput and reduce fees for decentralized applications. The platform enables users to stake Ether (ETH) in order to secure the network and earn rewards, while also supporting the issuance and trading of its native token. Core services include the execution of smart contracts, a contract upgrade mechanism that allows protocol improvements without disrupting existing deployments, and developer tooling for building on the layer‑2 environment. By operating on top of Ethereum, Shido inherits the security of the main chain while offering scalability benefits to its users. The project targets developers, institutional participants, and retail users seeking efficient blockchain infrastructure.

Headquartered in Sweden, Shido distinguishes itself through its focus on layer‑2 scaling solutions that integrate directly with Ethereum’s existing ecosystem. Its contract upgrade framework is a notable competency, intended to let the protocol evolve while preserving backward compatibility and minimizing governance overhead. The organisation emphasizes a modular architecture that separates consensus, execution, and data availability layers, a design choice aimed at enhancing flexibility and performance. Shido’s positioning within the broader blockchain sector is as a specialist infrastructure provider rather than a general‑purpose application layer. This technical emphasis has shaped its community outreach and partnership strategy, which prioritize collaborations with other Ethereum‑compatible projects.

On 29 February 2024, Shido experienced a significant security incident when attackers exploited a vulnerability in the contract upgrade mechanism of its Ethereum layer‑2 blockchain. The exploit allowed the malicious contract to gain unauthorized admin privileges, facilitating the transfer of control and the drainage of staked ETH from the platform. Approximately thirty‑five million dollars worth of assets were lost, leading to a sharp decline in the value of Shido’s native token. In response, the team paused the network, initiated an investigation, and identified the proxy contract flaw that enabled the bypass of admin controls. Despite attempts to negotiate with the perpetrators, the stolen funds were not recovered, and the incident prompted a broader review of the upgrade process.
