Cardano's next protocol upgrade may be getting closer to reality, according to a recent update from Intersect, a member-based organization for the Cardano ecosystem.
The incident underscores the critical need for rigorous security audits in crypto wallet software to prevent similar vulnerabilities and losses. SecondFi targets two-week recovery after Cardano wallet exploit drained $2.4M in ADA.
SecondFi says it has completed forensic investigations, taken a final balance snapshot and is preparing to return assets.
Cardano (ADA) has descended to price levels not witnessed since 2020 following a decisive breach of the $0.19–$0.20 support threshold. This technical breakdown has shifted momentum decisively toward sellers, while buying interest remains notably subdued at present valuations.
The number of daily active addresses on the Cardano network increased to 29,025 over the course of June 2026. ADA's social dominance reached 0.33% of all cryptocurrency-related discussions in the market. A security breach in the SecondFi web wallet protocol compromised nearly 129 million ADA tokens, with an estimated value of $20 million.
Cardano trades at multi-month lows as whales accumulate and bullish Futures positioning grows.
