Coinbase’s Base to Enable Private Stablecoin Transactions

Coinbase is actively working to enhance the privacy of cryptocurrency transactions through its Ethereum layer-2 network, Base. CEO Brian Armstrong announced that the team is introducing private stablecoin transactions, a significant step aimed at bolstering the security of users' financial information. Armstrong shared on X that this initiative has been under development since Coinbase acquired the Iron Fish team in March 2025.

This development has the potential to redefine privacy in the cryptocurrency space, enabling users to conduct secure transactions while retaining the option for transparency when necessary. The demand for such privacy features stems from users seeking to protect their assets from hackers and scammers. However, it is anticipated that regulatory bodies will closely monitor these tools due to concerns about their potential misuse for illicit activities.

Iron Fish Integration Enables Controlled Privacy

Base's new privacy feature is expected to integrate Iron Fish's established technology, which includes zero-knowledge proofs and "view keys." These components are designed to maintain transaction privacy while allowing users to selectively share limited information with authorities if required. Iron Fish has stated that these view keys can grant "read-only" access, which can be provided to tax or law enforcement agencies upon request.

Furthermore, Iron Fish utilizes the cross-chain bridge ChainPort, which incorporates real-time threat detection to ensure that "only clean funds" enter its network. This project currently offers privacy solutions across more than 20 blockchains, including Base. Through ChainPort, users can access a privacy-enhanced version of wrapped USDC, a stablecoin pegged to the U.S. dollar.

Despite these advancements, Brian Armstrong did not provide a response to community inquiries regarding the potential application of Know Your Client (KYC) checks to these private transactions. He indicated that additional details would be disclosed in the near future.

Coinbase Expands Operations with Echo Acquisition

In parallel with its privacy initiatives, Coinbase has announced the acquisition of Echo, an on-chain fundraising platform, for approximately $375 million. The exchange stated that this acquisition aims to enhance the transparency and accessibility of early-stage cryptocurrency funding.

Echo, founded by crypto influencer Cobie, facilitates fundraising directly from communities through private and public token sales. Its Sonar product has supported over 300 token sales, enabling projects to raise more than $200 million.

According to Yahoo Finance, Coinbase shares concluded the trading day at $338.62, marking a 1.50% decrease, and subsequently declined further to $332.50 in after-hours trading.

Coinbase is progressively moving towards a diversified cryptocurrency model that integrates robust privacy protections with transparent fundraising mechanisms. This strategy is intended to improve the security of blockchain transactions while ensuring broader financial access for a wider user base.
