Recently, friends paying attention to on-chain lending and stablecoin wealth management should have noticed an interesting phenomenon—arbitrage operations through lending protocols and financial products on exchanges via BNB Chain seem to be able to create a relatively stable income chain.

First, let's talk about why this topic is so hot right now. As the main lending protocol on BNB Chain, a leading platform currently has over $4.3 billion in assets locked, making it the largest USD1 ecosystem center on-chain. Their liquidity staking products (such as slisBNB and slisBNBx) have allowed many participants to earn substantial actual returns through activities like Launchpool and Megadrop. This wave has sparked enthusiasm among many to get involved more deeply.

So, how exactly does it work? Let me break down the practical process.

**Step 1: Prepare the underlying assets.** Choosing top assets like BTCB, ETH, and BNB as collateral is the safest approach, as they tend to have relatively low volatility and high liquidity. Suppose you prepare 1 BTCB (currently worth about $60,000), which will serve as the foundation for subsequent operations.

**Step 2: Enter the lending phase.** After connecting your wallet, deposit your BTCB into the protocol's collateral page, then choose to borrow USD1 stablecoins. A key point here—borrowing interest rates are roughly around 1%, but you need to monitor collateralization ratios, generally recommended to stay below 70%, to effectively avoid liquidation risks.

**Step 3: Cross over to the exchange side.** Withdraw the borrowed USD1 from the chain to a leading exchange (remember to choose a compatible chain, BSC is the most convenient), then go to the platform's Earn section. There, high-yield stablecoin wealth management products can sometimes offer annualized returns of 18%-20%. Just select a suitable lock-up period.

**Looking at the actual profit calculation:** Suppose you borrow 10,000 USD1 with a 1% cost. With an annualized return of 20% on the exchange's wealth management, the annual interest on the loan is 100 USD1, and the annual wealth management income is 2,000 USD1. The net annualized profit is 1,900 USD1, which is about a 19% net annualized return.

The reason this chain can work is simple—there's a clear interest spread between borrowing costs and wealth management returns. Of course, in actual operations, factors like liquidation risk, withdrawal fees, and token price volatility need to be considered, but the overall idea is as described. Many people are now deploying such strategies, and the timing is indeed good.
