Stablecoin account funding

Interactive Brokers clients can fund their brokerage accounts by sending USDC over Ethereum, Base or Solana to a wallet provided through Zerohash, which converts it to US dollars on receipt. The service opened to retail clients in December 2025 and was extended to round-the-clock funding in January 2026. Support for RLUSD and PYUSD had been announced but was not yet live on 5 October 2026.
