Friends who are recently engaged in stablecoin arbitrage probably share the same concern—which stablecoin should I use? With so many options on the market, like USDT, USDC, and various smaller tokens… it’s overwhelming.

But if you’ve done some in-depth research, you’ll notice that one stablecoin frequently appears in the portfolios of experts—USD1. It’s no coincidence; there’s a reason behind it.

**Cost is always the top priority**

What’s the biggest worry in arbitrage? Cost eating into all profits. The design of USD1 is very clever—it minimizes borrowing costs to the lowest possible level. Its interest rate model isn’t fixed; it adjusts in real-time based on market supply and demand through an algorithm. What does this mean? Your arbitrage window is larger, and the spread is easier to exploit. In the stablecoin arena, this is a clear competitive advantage.

**Liquidity is quite interesting**

Some stablecoins look good but are painfully difficult to use—high fees to deposit into exchanges, poor liquidity, and queues to convert to USDT. Although USD1 was born within specific DeFi protocols, it is a standard ERC-20 token. What does that mean? Basically, most mainstream exchanges recognize it. You can deposit to Binance or other top-tier exchanges without issues. Want to convert to USDT or USDC for investment? One click, instant. This liquidity advantage is especially obvious in practical operations.

**Decentralization and transparency**

Some might think this isn’t important, but it actually is crucial. Unlike certain stablecoins fully backed by a single company, USD1 is supported by over-collateralized assets on-chain. Fully transparent and auditable—you can see the backing assets at any time. This design fundamentally reduces the risk of “issuer collapse.” The level of trust is genuinely different.

**Interaction with the ecosystem**

Using USD1 means directly participating in the ecosystem. Every transaction you make contributes liquidity and activity to the protocol. In the long run, this participation could benefit you through governance rewards or other incentives. It’s somewhat like an indirect ecosystem dividend—uncertain, but the logic holds.

**Future expansion potential**

This is a bit technical but worth considering. As a native on-chain protocol stablecoin, USD1 is easier to integrate into complex structured products compared to those “air-dropped” from outside. Simply put, in the future, this stablecoin will have more and more applications in derivatives and portfolio strategies. Those who get in early will have more opportunities later.

**Why are these points so important?**

In arbitrage, the choice of vehicle can directly impact profit margins. Low costs mean bigger spreads; high liquidity ensures smooth execution; full decentralization reduces risks. When you combine these advantages, it’s clear why experienced traders tend to prefer this option.

Of course, every strategy carries risks. But in the stablecoin arena, USD1 has demonstrated significant overall competitiveness.
