At 1 a.m., I was staring at the 8,000 USD1 tokens recently credited to my wallet when I suddenly realized one thing: the stable returns in the crypto market have always been a matter of attention to detail, not luck.

The beginning of this was actually not complicated. I had accumulated a bunch of tokens on a certain public chain, which originally only had an annualized yield of a little over 2% on exchanges. Staking and mining faced lock-up risks, and I was always worried about missing out on market movements. It wasn't until I saw discussions in the community about a leading LSDfi protocol's stablecoin lending, mentioning that the borrowing interest rates were ridiculously low, that I was inspired to consider arbitrage — instead of letting assets sit idle, why not put them to work and generate interest?

**Why choose this stablecoin?**

I compared it to the mainstream options in the market at the time:

Borrowing USDT/USDC generally had annualized rates between 5% and 9%, with a narrow interest spread; niche stablecoins had liquidity concerns, and some even carried de-pegging risks, so I didn't dare to move them. But this USD1 was different — at the time, the borrowing annualized rate was only 0.7%, and it also offered considerable returns through a certain leading exchange's financial products. The interest spread was right there, and the opportunity was obvious.

Of course, I didn't act recklessly. I first looked into the background of the issuer: as a leading player in the LSDfi sector, its TVL has always been stable. USD1 itself is pegged to the dollar and is compliant, with no liquidity issues on the public chain. Combining these conditions gave me the confidence to execute this arbitrage plan.
