Oasis launches Ethereum-compatible privacy blockchain Sapphire

Decentralized applications could tap into improved privacy features as blockchain firm Oasis launches its confidential EVM-compatible blockchain Sapphire.
Sapphire and the Oasis Privacy Layer (OPL) are now live, allowing existing decentralized applications (DApp) on Ethereum Virtual Machine (EVM) networks to make use of the blockchain’s privacy-first features without having to carry out cross-chain swaps for respective tokens.
Cointelegraph reached out to Oasis to unpack the core components of the Sapphire blockchain and how it could help drive cross-chain Web3 development focused on privacy features for smart contracts.
Oasis Foundation director Jernej Kos said that OPL in particular allows developers that have built DApps on any EVM network to integrate a variety of Sapphire’s features without having to migrate to the Oasis blockchain:
“Being fully EVM-compatible means that developers can build private smart contracts in an environment that they are already familiar with, for example Solidity smart contracts running on the EVM as known from Ethereum.”
Kos added that the functionality also improves the ability to deploy DApps across different chains and make them compatible. Another example would be having a core DAO smart contract on Ethereum (ETH) while handling fully private voting on Sapphire, with end-results being sent back to the core DAO contract.
“In this way the privacy capabilities of Sapphire are exposed to any other chain.”
According to the Oasis Foundation director, the majority of DApps being developed on Oasis are privacy-centric and enable users with full control over their on-chain data to control how that gets shared and accessed. This is also evident in a list of different tools and platforms that have been built within the Oasis ecosystem.

Kos highlighted confidential decentralized exchanges, privacy-enabled blockchain gaming, account abstration, confidential NFTs, private voting, sealed-bid auctions, key management and decentralized identification as use cases that have come to the fore from builders on the Oasis chain.

Coinbase Tanks 11% Pre-Market After $1.5B Q2 Revenue Miss

Coinbase shares fell sharply after the company reported second-quarter earnings that missed expectations. Total revenue for the quarter came in at $1.5 billion, representing a 26% decline from the previous quarter.
The shortfall was largely driven by weaker-than-expected transaction revenue, which fell 39% quarter-over-quarter to $764 million.
Missing Expectations
In the official release, Coinbase revealed that its subscription and services revenue also declined 6% to $656 million. Despite efforts to reduce variable costs, operating expenses climbed 15% to $1.5 billion. Coinbase attributed this largely to the $307 million hit related to the data breach disclosed in May.
The crypto exchange recorded a net income of $1.4 billion, but this figure included $1.5 billion in pre-tax unrealized gains from strategic investments, including in Circle, as well as a $362 million pre-tax gain from its crypto investment portfolio. On an adjusted basis, net income stood at just $33 million, with adjusted EBITDA reaching $512 million.
Coinbase’s trading activity also underperformed the broader crypto spot market, as global and US crypto spot volumes declined 31% and 32% respectively. Meanwhile, its total trading volume fell 40% to $237 billion, and the consumer segment witnessed a 45% drop to $43 billion.
Consumer transaction revenue plunged 41% to $650 million, as volume shifted toward Simple trades amid low volatility. Institutional transaction revenue also saw a similar pattern, down 38% in both volume and revenue.
While Base Chain activity grew, other transaction revenue dropped 21% as average revenue per transaction declined.
As of the close on the previous trading day, Coinbase (COIN) shares were priced at $377.76, up slightly by $0.28. However, pre-market trading shows a sharp decline, with the stock down $42.30 (-11.20%) to $335.46. This steep drop suggests a strong negative reaction from investors, likely in response to recent earnings results.
Despite grappling with declining revenues and rising costs, Coinbase is doubling down on product innovation.
“Everything App”
Earlier this month, Coinbase rebranded its Wallet as the Base app, launching a crypto-focused “everything app” that merges trading, social media, USDC payments, mini-apps, and tokenized posts.
Announced at its “A New Day One” conference, the app runs on Coinbase’s Ethereum Layer 2 network and integrates Farcaster for social feeds, Zora for post tokenization, and encrypted XMTP chat. Users can earn from tips, interact with AI agents, and make one-tap payments.
The platform also introduced Base Pay for Shopify merchants and plans 1% USDC cashback in the US. The app is in beta, while a full public release and developer tools are expected soon.

Dogecoin Slides 8% but Long-Term Channel Holds, Can DOGE Rebound?

TL;DR
- Dogecoin dropped to $0.20, moving in a $0.23 to $0.20 range during heavy selling.
- Analysts see support in the long-term channel and a wedge pattern aiming for $0.265.
- Large holders bought 310 million coins, while Bit Origin added 40 million to reserves.
Dogecoin Records Sharp Daily Decline
Dogecoin (DOGE) fell 8% in the past 24 hours, dropping from $0.22 to $0.21. This was one of the steepest daily moves for the token in July. The price action moved within a $0.23 to $0.20 range, facing resistance at the top and heavy selling near the session close.
However, trading volumes spiked, with a midnight surge to 1.25 billion DOGE, which points to large liquidations and cascading sell orders from leveraged positions.
Dogecoin trades at $0.20 as of press time, down 11% over the past week, giving it a market cap of $31 billion.
Long-Term Channel Remains Intact
Trader Tardigrade shared a 1-month chart showing DOGE inside a long-term ascending channel that has held since 2014. DOGE has often bounced from the lower boundary of this channel, shown in pink on the chart.

— Trader Tardigrade (@TATrader_Alan) August 1, 2025
Meanwhile, the current price is near the lower-middle part of the channel, an area that has led to multi-month rallies when the trend held. Dogecoin’s long-term structure stays intact while it trades within this ascending channel, even after the recent decline.
In addition, Trader Tardigrade also noted that Dogecoin’s monthly candle closed as the third consecutive bullish engulfing candle, which he described as a setup for a potential “move to Valhalla.”
Short-Term Wedge and Institutional Activity
Ali Martinez noted that DOGE may be forming a falling wedge on the 1-hour chart, with a projected target of $0.265. A move above $0.229–$0.230 would confirm bullish momentum, while $0.215–$0.210 remains key support if the wedge fails.

Institutional wallets acquired 310 million DOGE during the correction. Bit Origin added 40 million DOGE to its treasury under a $500 million diversification program. Broader crypto markets remain pressured by macroeconomic uncertainty, with inflation and equity risk shaping short-term demand.
