Coinbase, a leading U.S. cryptocurrency exchange, announced plans to raise $2 billion through a private offering of convertible senior notes, split evenly between 2029 and 2032 maturities, with an option for an additional $300 million.
The notes, offered to qualified institutional buyers, aim to fund general corporate purposes, including working capital, acquisitions, and capped call transactions to reduce potential dilution. This move follows a Q2 revenue decline and a 15% drop in COIN shares, though some analysts see it as a buying opportunity.
Separately, Coinbase’s Ethereum Layer-2 network, Base, experienced its first major outage since 2023, halting block production for 19 minutes on August 5, 2025, due to a sequencer failure. The issue, reported at 06:15 UTC, was resolved by 06:44 UTC, with no loss of funds. The outage highlights centralization risks in Layer-2 designs, prompting calls for more robust, decentralized solutions.

The outage, even though short, temporarily disrupted deposits, withdrawals, and decentralized application (dApp) functionality, potentially shaking user confidence. Social media platforms like Reddit, X, and Telegram saw heightened activity with user concerns, memes, and speculation, indicating a hit to perceived reliability.
With over $4.2 billion in total value locked (TVL) on Base, including $1.5 billion tied to protocols like Morpho, the halt paused DeFi operations, causing transaction congestion and delays. This could deter users and developers relying on Base for time-sensitive financial activities.
Base’s rapid growth, including surpassing Solana in daily token launches (54,000 on July 27), positions it as a key player in Ethereum’s scaling ecosystem. Outages undermine its reputation as a scalable, reliable solution, which is critical for mainstream adoption.
The outage, caused by an “unsafe head delay” linked to Base’s centralized sequencer, highlights a critical flaw in its architecture. Unlike Ethereum’s mainnet, which is secured by thousands of validators, Base’s reliance on a single Coinbase-operated sequencer means a single point of failure can halt the entire network.
Critics and decentralization advocates are pushing for Base to adopt backup sequencers or a decentralized rollup architecture to mitigate such risks. This incident amplifies long-standing concerns about centralization in Layer-2 designs, which could limit trust from developers and institutions.
The outage coincided with a surge in network activity, driven by features like Basenames and integrations with platforms like Zora and Farcaster. This suggests that rapid scaling may have outpaced infrastructure readiness, exposing technical limitations.
Coinbase has not yet released a detailed post-mortem, leaving questions about whether recent upgrades, like Flashblocks, contributed to the issue. This lack of clarity could fuel skepticism about Base’s operational maturity.
The outage is not isolated, as other blockchains like Sui, TON, Avalanche, and Solana have faced similar disruptions in 2024. However, Base’s role as a Coinbase-backed, high-profile Layer-2 makes its failures more scrutinized, given its 110 million-user ecosystem and partnerships with major brands.
Why Base’s Reliability Is Critical at This Stage
Base leverages Coinbase’s 110 million verified users, making it a gateway for mainstream Web3 adoption. Downtime risks alienating this large audience, particularly retail users and developers building dApps for social media, gaming, and DeFi.
As the second-largest Ethereum Layer-2 by TVL ($13 billion) and a leader in transaction volume, Base competes with Arbitrum, Optimism, and other scaling solutions. Reliability is a key differentiator, as users and developers prioritize networks with consistent uptime for financial and operational stability.
Base is integral to Ethereum’s scaling strategy, handling high transaction volumes at lower costs while maintaining Ethereum’s security. Disruptions undermine its role as a scalable complement to Ethereum’s mainnet, especially as Layer-2s become mission-critical for Ethereum’s ecosystem.
Base hosts a vibrant ecosystem of dApps, including Blackbird, CyberConnect, and Echelon Prime, which rely on its performance for gaming, social media, and DeFi applications. Downtime disrupts developer operations and could deter new projects from building on Base, slowing ecosystem growth.
Coinbase’s $2 billion convertible notes offering signals aggressive expansion plans, likely tied to enhancing Base and other services. Outages could undermine investor confidence in Coinbase’s ability to execute, especially amid a Q2 revenue decline and a 15% drop in COIN shares.
The Base outage, while resolved quickly, underscores the fragility of centralized Layer-2 designs and the high stakes for reliability at this stage of its growth. As a cornerstone of Ethereum’s scaling ecosystem and Coinbase’s Web3 strategy, Base’s uptime is critical to maintaining user trust, developer confidence, and market leadership.
