Eligible clients can now send USDC from personal wallets to secure accounts managed by ZeroHash. The system automatically converts incoming stablecoins to U.S. dollars for immediate trading access.
The Nasdaq-listed brokerage plans to add Ripple’s RLUSD and PayPal’s PYUSD next week. This expansion will give clients three stablecoin options for account funding.
The service operates across Ethereum, Solana, and Base blockchains. This multi-chain approach removes dependence on traditional banking hours and wire transfers.
Fast Funding Cuts Transaction Costs
CEO Milan Galik explained the competitive advantage in the company’s release. “Stablecoin funding provides international investors with the speed and flexibility required in today’s markets.”
Clients can move from deposit to active trading in minutes. This speed represents a major upgrade over conventional cross-border wire transfers.
Interactive Brokers waives deposit fees for stablecoin funding. Users only pay standard blockchain network fees for their transfers.
ZeroHash applies a 0.30% conversion fee when changing stablecoins to dollars. The company sets a $1 minimum fee per transaction.
Building on December Launch
The announcement extends Interactive Brokers’ December rollout of stablecoin funding for U.S. retail accounts. The firm continues pushing into crypto-adjacent services as competition heats up.
