Top stock broker Interactive Brokers (IBKR) officially announces a major move — the platform now supports direct deposits with stablecoin USDC.

Here's the key point: supports cross-chain deposits from mainstream blockchains such as Ethereum, Solana, and Base, with a 0.3% conversion fee per transaction. In terms of limits, a maximum of $25,000 can be deposited daily, with a monthly cap of $250,000.

However, there is a lock-up period restriction. Funds deposited via stablecoins need to be frozen for 30 business days before they can be withdrawn — this design is likely a risk control measure.

This is an official recognition of the stablecoin ecosystem by traditional finance and marks a breakthrough in digital assets breaking the traditional deposit channels of brokers. For users already holding USDC or other stablecoins, this adds another way to allocate to the stock market.
