Interactive Brokers has introduced a new feature allowing 24/7 account funding using USDC, enabling users to deposit and trade at any time. Supported by Zerohash, users can transfer USDC via Ethereum, Solana, or Base networks to a designated wallet. Once received, the funds are automatically converted to USD and credited to the brokerage account, with a conversion fee of 0.30% per transaction (minimum $1), plus network fees. Interactive Brokers plans to expand support to more stablecoins, including Ripple's RLUSD and PayPal's PYUSD, with these options expected to be available as early as next week.
