A major security incident hit Step Finance, a portfolio-tracking protocol on the Solana blockchain, when several of its treasury wallets were accessed by an attacker during Asia-Pacific hours. On-chain traces show approximately 261,854 SOL—valued at about $27.2 million at the time—was unstaked and moved out of addresses controlled by the project, and subsequent activity appears to have driven heavy market sell pressure. The project's native token, STEP, suffered an immediate and extreme market reaction, plunging more than 90% within a day to trade near $0.0016, indicating near-total loss of market confidence. Step Finance has announced remediation actions but has not provided a technical root-cause assessment, leaving open whether the compromise originated from private key theft, an operational lapse, or a smart-contract vulnerability. Blockchain security firm analysis was used to attribute the on-chain transfers, but no definitive public attribution of the attacker or recovery of funds has been reported. The episode compounds a well-documented pattern in which many DeFi protocols fail to regain footing after large treasury or bridge exploits, primarily because of cascading liquidity exits and trust erosion. Operationally, the incident exposes the concentration risks associated with protocol-owned treasuries on public chains and underscores the need for stronger multi-party custody, time-locked governance, and active monitoring. Market participants are likely to reassess exposure to projects whose treasuries hold operational responsibilities that directly affect tokenomics. For Step Finance, the immediate regulatory and partnership fallout could be substantial: counterparties and institutions tend to limit interaction with projects under active compromise. Longer term, the project will face an uphill battle restoring economic utility to STEP and re-establishing secure governance processes if it aims to retain any meaningful role in Solana’s DeFi ecosystem. The case also serves as a reminder that rapid, clear, and technically detailed incident response is critical; silence or vagueness in the hours after a breach accelerates price collapse. Security firms advising projects argue that decisive containment, transparent forensic updates, and concrete remediation steps are the only realistic tools to slow contagion in token markets. Investors and on-chain services should treat protocol treasuries as high-risk operational attack surfaces and demand verifiable custody assurances and audit trails. Ultimately, the breach will be judged not just by the dollar value moved but by how Step Finance manages recovery, communicates evidence, and reforms controls to prevent recurrence.

Bybit Converts Solana Volatility into Yield and Market Share During Token Rally
Bybit credits an integrated set of discovery, trading and staking products with capturing a disproportionate share of a recent Solana-led market surge, citing a 10x peak on SKR and large single-day volumes. The exchange argues that combining early token listings, deep spot liquidity and liquid-staking wrappers lets users translate short-term price moves into yield opportunities, though sustainability and regulatory risk remain material.
