Clients can send USDC on Ethereum, Solana, or Base, Interactive Brokers said. After the transfer, the brokerage converts USDC into U.S. dollars and credits the account.
Interactive Brokers said it will add Ripple USD (RLUSD) and PayPal USD (PYUSD) support next week. The firm also said it first allowed retail investors to fund individual brokerage accounts with USDC in December.
Interactive Brokers zerohash Partnership Adds USDC Deposits on Ethereum, Solana, Base
The Interactive Brokers zerohash partnership supports USDC deposits on three blockchains. Interactive Brokers listed Ethereum, Solana, and Base as the supported networks.
Interactive Brokers said the deposit flow ends with automatic conversion into U.S. dollars. The converted balance then appears as credited funds in the client’s brokerage account.
Earlier in the year, the company reportedly considered launching its own stablecoin. However, the Thursday update focused on stablecoin deposits through USDC, with more stablecoins scheduled next.
Stablecoin Funding Targets Cross Border Transfer Costs and Delays
Interactive Brokers said stablecoin funding addresses a “critical pain point” for access to global capital markets. The firm said traditional cross border funding through fiat wire transfers can be costly and slow.
The brokerage said stablecoin deposits can offer near instant settlement. It also said stablecoin transfers can reduce dependence on business hours.
“Stablecoin funding provides international investors with the speed and flexibility required in today’s markets,”
said Milan Galik, CEO of Interactive Brokers.
“Clients can transfer funds and begin trading within minutes, while also reducing transaction costs.”
Interactive Brokers Crypto Services Expanded From Bitcoin and Ether to SOL and XRP
Interactive Brokers crypto services started in 2021, the firm said. The platform initially supported Bitcoin (BTC) and Ether (ETH) for trading.
Later, Interactive Brokers added more tokens. The firm said it added Solana (SOL) and XRP in 2025.
The stablecoin deposit feature adds another crypto related rail. It focuses on funding brokerage accounts with USDC, then converting it into U.S. dollars.
Stablecoin Market Cap Passed $300 Billion and Now Sits Above $310 Billion
The stablecoin market cap passed $300 billion for the first time in October, according to the report. It said the sector reached that level after year to date growth of 46.8% at that time.
As of Friday, the total stablecoin market cap stood above $310 billion, according to DefiLlama. The report said the growth came mainly from Tether (USDT), USDC, and Ethena Labs’ yield bearing stablecoin USDe (USDE).
The Interactive Brokers update links that stablecoin growth to brokerage funding. It allows USDC deposits and sets a timeline for RLUSD and PYUSD support next week.
