Coinbase is taking a major step to improve privacy in crypto transactions. The exchange’s Ethereum layer-2 network, Base, will soon support private stablecoin transactions, according to CEO Brian Armstrong. He confirmed that this initiative has been in development since Coinbase acquired the Iron Fish team in March 2025.

The feature aims to allow users to shield their financial data while retaining transparency when necessary. This move addresses growing concerns over hackers, scammers, and unwanted exposure, providing a more secure way to transact in crypto.

Iron Fish Technology Brings Controlled Privacy

The privacy tools stem from Iron Fish’s expertise, which includes zero-knowledge proofs and “view keys.” These technologies enable private transactions while allowing selective sharing with authorities for tax or legal compliance. Through cross-chain bridge ChainPort, which features real-time threat detection, only verified funds enter the network. Users can access privacy-enabled versions of stablecoins like USDC across more than 20 blockchains, including Base.

Despite community questions about Know Your Client (KYC) checks, Armstrong has not provided specifics, stating only that further updates are coming soon.

Coinbase Expands With Echo Acquisition

Alongside privacy initiatives, Coinbase announced the $375 million acquisition of Echo, an on-chain fundraising platform. Founded by crypto influencer Cobie, Echo enables projects to raise funds directly from communities through public and private token sales. Its Sonar product has facilitated over 300 token sales, totaling more than $200 million.

This acquisition aligns with Coinbase’s broader strategy to balance privacy and transparency. By blending secure transactions with accessible fundraising, the platform aims to make blockchain interactions safer while keeping crypto projects open to a wider audience.

Toward a Safer, Transparent Crypto Ecosystem

Coinbase is positioning itself at the forefront of crypto privacy and accessibility. With Base’s private transaction capabilities and Echo’s fundraising tools, the exchange demonstrates a commitment to protecting user data while promoting transparency—a delicate balance that could redefine standards in the crypto world.
