Interactive Brokers Launches 24/7 Stablecoin Funding via USDC and Zerohash

Interactive Brokers has launched round-the-clock account funding using Circle’s USDC stablecoin, marking a notable shift in how clients can move money into the markets.

Specifically, the Nasdaq-listed brokerage stated that the update allows traders to fund accounts at any time and begin trading immediately, without being constrained by traditional bank operating hours.

• Interactive Brokers announced USDC-based account funding on Thursday.
• The feature allows 24/7 funding and trading, unlike bank wire transfers.
• The integration uses infrastructure from Zerohash, a crypto services provider.
• The firm plans to add RLUSD and PYUSD as early as next week.

Under the new system, clients can send USDC from their personal crypto wallets to a wallet created by Zerohash. At launch, the service supports transfers on Ethereum, Solana, and Coinbase’s Base network, according to the company.

Once the stablecoin is received, the system automatically converts the USDC into U.S. dollars. Then, the converted funds are credited directly to the client’s brokerage account, thereby eliminating the waiting periods typically associated with bank-based funding methods.

Interactive Brokers said stablecoins provide a faster and more accessible alternative to traditional payment rails. In contrast, bank wire transfers are constrained by local business hours and may result in delays to trading activity, particularly for international clients.

By comparison, stablecoin transactions run continuously and can be initiated from most regions worldwide. The firm said this always-on structure enables clients to access global markets without timing constraints.

Chief Executive Officer Milan Galik said the move addresses longstanding concerns around speed and cost for global investors. In a company statement, he noted that clients can fund accounts and begin trading more quickly while reducing transaction expenses.

Overall, the brokerage framed the update as a response to evolving client expectations and rising demand for flexible, real-time funding options.

The stablecoin integration relies on Zerohash, a business-focused crypto infrastructure provider backed by Interactive Brokers. Specifically, Zerohash manages wallet generation, asset conversion, and settlement.

For each deposit, Zerohash charges a 0.30% conversion fee, with a minimum fee of $1. Additionally, standard blockchain transaction fees apply, depending on the network used.

Interactive Brokers first enabled USDC funding for individual retail accounts in December. The latest update expands that capability to full, 24/7 availability.

Looking ahead, the firm plans to support additional stablecoins, including Ripple’s RLUSD and PayPal’s PYUSD. Reuters reported last year that Interactive Brokers had also explored the possibility of issuing its own stablecoin.

Founded in 1978, Interactive Brokers is an electronic brokerage best known for its low-cost trading services. Notably, the company entered crypto trading in late 2021 through a partnership with Paxos, initially supporting BTC, ETH, BCH, and LTC.

Later, in 2025, it expanded its digital asset offerings to include ADA, SOL, DOGE, and XRP, underscoring its broader push into crypto-related services.
