Electronic brokerage firm Interactive Brokers has expanded its crypto-related services by allowing clients to fund their trading accounts using stablecoins that are automatically converted into U.S. dollars.
The company said on Thursday that it has partnered with zerohash to enable round-the-clock account funding with USDC across multiple blockchains, including Ethereum, Solana and Base. This move allows clients to bypass traditional bank wires and the limitations of standard banking hours.
According to Interactive Brokers, stablecoin deposits are converted into U.S. dollars upon receipt and credited directly to client accounts. The broker added that support for additional dollar-pegged stablecoins, including Ripple USD and PayPal USD, is expected to be rolled out next week.
Interactive Brokers first introduced USDC funding for retail brokerage accounts in December and had previously explored launching its own stablecoin, according to earlier disclosures.
Stablecoins target funding inefficiencies
The company said the use of stablecoins addresses a major challenge in accessing global capital markets, as cross-border fiat transfers are often slow and expensive. By contrast, stablecoin-based funding offers near-instant settlement, lower costs, and continuous availability.
“Stablecoin funding gives international investors the speed and flexibility today’s markets demand,” said Milan Galik. “Clients can move funds and start trading within minutes, while also cutting transaction expenses.”
Interactive Brokers began offering cryptocurrency trading services in 2021, initially supporting Bitcoin and Ether. Over time, it has expanded its digital asset offering to include additional tokens such as Solana and XRP.
The stablecoin market has grown rapidly in recent years as governments, financial institutions and companies increasingly explore tokenized money. The sector’s total market capitalization surpassed $300 billion in 2025 and has continued to expand, driven largely by major dollar-backed stablecoins.
According to data from DefiLlama, the overall stablecoin market capitalization now exceeds $310 billion.
