Electronic brokerage giant Interactive Brokers has broadened its crypto services, now allowing clients to fund their accounts using stablecoins.
On Thursday, the firm announced a partnership with stablecoin infrastructure provider ZeroHash, enabling clients to deposit USDC on the Ethereum, Solana, or Base blockchains. Deposited stablecoins are automatically converted into U.S. dollars and credited to the client’s brokerage account. The company plans to add support for Ripple USD and PayPal USD next week.
Interactive Brokers first permitted retail investors to fund individual accounts with USDC in December, and the company reportedly considered launching its own stablecoin earlier in the year.
Stablecoins to solve “critical pain point” for investors
Interactive Brokers said stablecoins will help address a “critical pain point” in accessing global capital markets, where traditional cross-border funding via fiat wire transfers can be slow and costly.
Stablecoin funding, by contrast, offers near-instant settlement, lower fees, and operates around the clock without business-hour constraints.
“Stablecoin funding provides international investors with the speed and flexibility required in today’s markets,” said CEO Milan Galik. “Clients can transfer funds and begin trading within minutes, while also reducing transaction costs.”
Interactive Brokers first launched crypto services on its trading platform in 2021, initially offering Bitcoin and Ether, and expanded to additional tokens such as Solana and XRP in 2025.
The stablecoin sector saw strong growth throughout 2025, as countries and banks explored their use. Market capitalization for stablecoins surpassed $300 billion for the first time in October, growing 46.8% year-to-date, driven primarily by Tether, USDC, and Ethena Labs’ yield-bearing stablecoin USDe. As of Friday, the total stablecoin market cap stands above $310 billion, according to DeFi data aggregator DefiLlama.
