- Stablecoin funding starts as Interactive Brokers now accepts USDC deposits.
- Clients can move USDC anytime through Ethereum, Solana, or Base networks.
- More stablecoins like RLUSD and PYUSD will be added for account funding.
Interactive Brokers has started allowing clients to fund brokerage accounts using stablecoins. The US-based electronic brokerage confirmed the rollout for USDC deposits. The move strengthens its payment options while linking traditional trading access with blockchain transfer rails.
The firm said customers can now send USD Coin (USDC) to fund their accounts. The deposit is automatically converted into US dollars after arrival. After that, the converted sum is immediately added to the client’s trading balance.
Interactive Brokers clarified that clients will not hold USDC inside the brokerage platform. The stablecoin does not remain in the account as a digital asset. Instead, it functions only as a funding rail for moving dollar value.
Stablecoin Transfers Enabled Through Zerohash Partnership
The broker is offering the stablecoin service through a partnership with zerohash, a crypto infrastructure firm. Clients can send USDC using Ethereum, Solana, or Base networks. Deposits can be made at any time, including weekends and holidays.
That round-the-clock access removes reliance on traditional wire transfers. Banking rails often operate only during business hours. Transfers may also involve multiple intermediaries in cross-border flows.
Interactive Brokers stated that the feature targets international clients. These users often face delays in standard bank transfers. They may also deal with higher fees and additional processing steps.
The company also confirmed plans to support more stablecoins in the future. It listed Ripple’s RLUSD and PayPal’s PYUSD as upcoming options. The additions would expand account funding methods beyond USDC.

The stablecoin rollout follows earlier signals from the brokerage. In mid-2025, Founder and Chairman Thomas Peterffy said the firm was studying stablecoin integration. He discussed whether dollar-backed tokens could support 24/7 funding while the company remained cautious on crypto risk.
Stablecoin Growth Aligns With Broker’s Compliance Focus
Interactive Brokers also widened its crypto trading lineup in 2025. In April 2025, it added Chainlink, Avalanche, and Sui for client trading. Those tokens joined existing offerings such as Bitcoin, Ethereum, Solana, XRP, and Dogecoin.
The broker did not create its own stablecoin but instead selected existing issuers. The emphasis was put on settlement and compliance. The strategy also minimized the interest in regulating stablecoin reserves or token operations.
The move occurs amidst buoyant stablecoin growth within finance. The use of stablecoins as digital versions of the US dollar becomes more prevalent. They are high speed on blockchain networks and are able to accommodate faster settlement.
According to DeFiLlama data, the stablecoin market surpassed $300 billion in total value in October 2025. The report attributed the large scale of growth to Tether USDT, Circle USDC, and USDe in Ethena Labs. The market had surged beyond $310 billion towards the close of 2025.
Interactive Brokers is not replacing banking with stablecoins, they use it as a payment rail. The model enables users to access brokerage accounts at a quicker rate using blockchain routes of transfers. Still, it finishes in US dollars within the trading platform.
