Interactive Brokers just made a quiet but important move that pulls crypto and traditional markets closer together.
The global brokerage giant now lets some clients fund their trading accounts directly with USDT and USDC. Using money that sits in a crypto wallet instead of a bank account.
How the New Funding Option Works
According to Bloomberg, Interactive Brokers is rolling out the ability to top up balances with stablecoins. In simple terms, a stablecoin is a digital token that tracks the value of one U.S. dollar and is backed by reserves. Its price stays close to a dollar most of the time. Instead of wiring cash through a bank, eligible users can move those tokens from a personal wallet to the brokerage. Here, they are converted into fiat buying power.

The process relies on Zero Hash, a crypto infrastructure provider that handles stablecoin transfers and operates around the clock. Because Zero Hash runs 24/7, deposits are not limited by banking hours or cut off times. For an active trader, that can mean topping up an account on Sunday night to catch a Monday opening move, rather than waiting for a wire to clear. It also reduces friction for investors who already hold part of their wealth in stablecoins and want to rotate into stocks. Also, for options or futures without a slow trip through the banking system.
More About Altcoins
Cardano founder Charles Hoskinson has hinted that major stablecoins could be on the way to the network, noting that the current roadmap includes options such as USDC and USDT alongside bridges, oracles, analytics tools, and custodial services. Framing it as “the first menu of the 12 days of Christmas,” he suggested that this is only the opening set of possible integrations, with more to come.

For Cardano users and investors, the signal is clear: the ecosystem is actively exploring deeper links with leading stablecoins and core infrastructure providers, which could improve liquidity, attract new developers, and make it easier for institutions to build on the chain.
