Coinbase DEX has rolled out decentralized exchange (DEX) trading directly inside its app, giving users access to millions of onchain assets without leaving the platform. The launch is live for U.S. users outside New York State and runs on Coinbase’s Ethereum Layer 2 network, Base.

The feature introduces an integrated self-custody wallet, letting traders buy, sell, and manage tokens from the same interface they already use. Moreover, Coinbase is covering all network fees at launch, removing one of the main barriers to decentralized trading.

Faster Access to Onchain Markets

With the new Coinbase DEX integration, users can trade tokens within moments of their creation on Base. The initial rollout includes Base-native assets from projects like Virtuals AI Agents, Reserve Protocol DTFs, SoSo Value Indices, Auki Labs, and Super Champs. Support for new assets will be added in batches to maintain stable performance.

Trades are routed through Coinbase DEX aggregators that scan platforms like Aerodrome and Uniswap to secure the best available prices. Market data and risk insights are pulled directly from onchain sources, with Coinbase blocking access to tokens flagged as malicious by third-party security partners.

“A new era of access, going from just 300 assets yesterday to millions before long.” -Coinbase

Expansion Beyond Base

Coinbase plans to expand DEX trading to more networks, starting with Solana, and eventually to more countries. This move combines centralized convenience with decentralized freedom, offering portfolio management, fiat integration, and instant access to emerging tokens.

The company is positioning the update as part of its “everything exchange” vision, aiming to merge traditional listings with rapid onchain access. For traders and builders, this could mean faster entry to markets and a larger audience from day one.

USDC issuer Circle has announced plans to launch its own open Layer-1 blockchain, Arc, later this year. The network is designed specifically for stablecoin payments, foreign exchange, and capital markets, a move the company calls “the next era of stablecoin-native applications.” The announcement was made on August 12 through Circle’s official blog and X post: 

Arc will be EVM-compatible and use USDC as its native gas token. This allows users to pay predictable, dollar-denominated transaction fees without holding volatile crypto assets. Other features include a built-in FX engine, deterministic sub-second settlement finality, and opt-in privacy controls.

Circle says Arc will be fully integrated across its platform and remain interoperable with the 24 blockchains already supporting USDC. The blockchain will run on Malachite, a high-performance consensus engine acquired from Informal Systems, and its core software will be released under an open-source license.

Based on their announcement, use cases for Arc range from cross-border payments and stablecoin FX markets to tokenized assets and on-chain credit systems. Circle aims to give developers and institutions a unified foundation to build stablecoin-powered applications at scale.

Arc will enter private testnet in the coming weeks, with a public testnet expected this fall and mainnet beta in 2026. As Circle put it, Arc is intended to be “the home for all forms of digital money and tokenized value,” bridging enterprise needs with the openness of public blockchain infrastructure.

Stripe is taking a major step into crypto infrastructure. The $92 billion fintech giant is developing a new payments-focused blockchain, Tempo, in partnership with crypto venture firm Paradigm, according to a now-removed job posting spotted by Fortune on August 3. The posting was taken down shortly after Fortune reached out to Stripe and Paradigm for comment, highlighting the stealth nature of the project.

The listing, posted on the Blockchain Association’s website, described Tempo as a “high-performance, payments-focused” layer 1 blockchain. It said the project is in stealth mode, run by a five-person team, and compatible with Ethereum’s coding language. Applicants were expected to have experience marketing to a Fortune 500 audience, hinting at the scale of Stripe’s ambitions.

Tempo follows a string of strategic acquisitions that give Stripe the building blocks for a full stablecoin payments stack. Last October, Stripe CEO Patrick Collison confirmed the acquisition of stablecoin infrastructure provider Bridge for $1.1 billion. In June, he announced on X that Stripe had acquired crypto wallet developer Privy.

Together, these moves position Stripe to control payment integration, wallet software, and now potentially its own blockchain infrastructure.

The push comes as the $270 billion stablecoin sector gains momentum. Specifically, the interest surged after President Donald Trump signed the GENIUS Act into law in July, providing U.S. regulatory clarity for stablecoins. Big Tech players like Meta, Apple, and Airbnb are exploring similar integrations, but Stripe’s rapid moves may put it ahead of the pack.

Stripe and Paradigm have not commented publicly on Tempo, and it’s unclear whether the blockchain will have its own native token. However, Paradigm cofounder Matt Huang sits on Stripe’s board, suggesting close alignment between the two companies.

If launched, Tempo could give Stripe control over another critical layer of the stablecoin ecosystem, the infrastructure that processes transactions, solidifying its position as a leader in next-generation payments technology.
