Interactive Brokers (Nasdaq: IBKR) has launched 24/7 account funding using USDC, allowing clients to fund their brokerage accounts and begin trading within minutes, effectively enabling round-the-clock trading.

The new feature is powered by Zerohash, a B2B crypto and stablecoin infrastructure provider backed by Interactive Brokers. Clients can transfer USDC from their personal wallets on Ethereum, Solana, or Base, with the stablecoin automatically converted into U.S. dollars and credited to their brokerage accounts.

CEO Milan Galik said stablecoin funding offers faster settlement, lower costs, and greater flexibility for international investors compared with traditional methods such as wire transfers, which are limited by local banking hours.

Zerohash charges a 0.30% conversion fee per deposit, with a minimum fee of $1, in addition to standard blockchain transaction fees. Interactive Brokers plans to expand support to additional stablecoins, including Ripple’s RLUSD and PayPal’s PYUSD, as early as next week.

Founded in 1978, Interactive Brokers is a major electronic brokerage known for its low-cost trading model. The firm entered crypto trading and custody in 2021 and has since expanded its digital asset offerings.
