Interactive Brokers Group, Inc., IBKR

The Nasdaq-listed broker partnered with digital asset infrastructure provider ZeroHash to enable the new funding method. Clients can send USDC from their crypto wallets to a secure wallet provided through the partnership.

The company plans to expand stablecoin support next week. Ripple’s RLUSD and PayPal’s PYUSD will join USDC as accepted deposit options.

Deposits work across three major blockchains. The service supports Ethereum, Solana, and Base networks for stablecoin transfers.

Once received, stablecoins automatically convert to U.S. dollars. The funds then credit to the client’s brokerage account for trading across Interactive Brokers’ markets.

Fee Structure for Stablecoin Deposits

Interactive Brokers does not charge fees for stablecoin deposits. However, users must pay blockchain network fees for their transactions.

ZeroHash applies a 0.30% conversion fee on each deposit. The minimum fee is $1 per transaction.

Trading Platform Expansion

The move builds on Interactive Brokers’ recent crypto service expansion. The firm began offering stablecoin account funding for U.S. retail clients in December.

Interactive Brokers has invested in ZeroHash as part of its digital asset strategy. ZeroHash previously raised $104 million at a $1 billion valuation.

The company first added crypto trading to its platform in 2021. Bitcoin and Ether were the initial offerings for clients.

Additional cryptocurrencies joined the platform in 2025. Solana and XRP became available for trading this year.

USDC ranks as the world’s second-largest stablecoin by market cap. At press time, USDC held a market capitalization of $75.68 billion.

Tether remains the largest stablecoin with $186.90 billion in market cap. The total stablecoin market now exceeds $310 billion according to DefiLlama.

Interactive Brokers shares climbed over 3% on Thursday following the announcement. The stock hit a lifetime high of $75 during trading.
