Polar integrates Rhino.fi to power seamless cross-chain onboarding and payments

Simplifying global finance through one address and one API

Polar is building modern financial tools for global workers in the U.S., helping them save, invest and send money home faster. By combining traditional banking features like U.S. account numbers and interest on savings with onchain assets, Polar bridges the gap between fintech and crypto.

To make this experience seamless, Polar has integrated our Smart Deposit Addresses (SDA). This enables users to fund their accounts with USDT or USDC from any chain, while Rhino.fi automatically bridges, swaps and settles funds on Base, where Polar operates.

Enabling borderless finance

For millions of people working abroad, managing remittances across borders remains slow and expensive. Sending funds home or accessing savings in another country often involves intermediaries, high fees and long settlement times.

Cross-chain technology provides a real world solution to this problem. By connecting different onchain ecosystems, it enables fast, low-cost transfers of stable value, no matter where users are or which chain they use.

Polar uses Rhino.fi’s Smart Deposit Addresses (SDA) to simplify cross-chain deposits and liquidity management.

Instead of manually bridging, swapping, or worrying about the right network, users can send funds from any supported chain or even a centralized exchange. Rhino.fi’s infrastructure automatically bridges, swaps, and settles the assets on the target chain.

What this means for Polar’s users

Users can:

• Fund their accounts with USDC or USDT from any supported chain

• See their balance update instantly after the transaction

• Invest in assets such as cbBTC and WETH directly within the Polar app

This gives Polar users a truly seamless experience while Rhino.fi ensures instant, error-free settlement with zero slippage across 20+ chains.

Powering the next wave of fintech

Polar’s integration shows how fintech teams can use Rhino.fi’s cross-chain liquidity layer to bring borderless, efficient finance to their users.

By abstracting away chain complexity, companies can onboard users, accept payments and manage liquidity across ecosystems through one API. This is what the next generation of global finance looks like: cross-chain as the foundation for truly cross-border finance.
