Interactive Brokers partners with Zero Hash to accept USDC stablecoin deposits on Ethereum, Solana and Base

Interactive Brokers has expanded its digital asset services by enabling clients to fund brokerage accounts with USDC stablecoins on Ethereum, Solana and Base, with deposits automatically converted into U.S. dollars. The firm plans to add support for RLUSD and PYUSD next week and says stablecoin funding can ease cross-border capital access by cutting costs and settlement times. The move follows its earlier rollout of USDC funding for retail brokerage accounts in December and comes amid a stablecoin market cap that recently exceeded $310 billion.
