Holding mainstream assets like BTCB, ETH, BNB but not knowing how to make them appreciate? Or holding these blue-chip coins but struggling to find a safe and stable yield-generating solution? Actually, many people are facing the same dilemma: assets lying idle in wallets, uncertain market trends, and too many investment options that leave people at a loss.

Recently, I discovered an interesting arbitrage idea—using a lending protocol on-chain to lend out stablecoins at low interest, then investing these stablecoins into financial products to earn returns, achieving appreciation through interest rate differentials. This logic sounds simple, but executing it effectively requires the right tools and timing.

There is a lending platform operating on BNB Chain with long-term stable lending rates around 1%, which is highly competitive in the industry. The platform supports using mainstream assets like BTCB, ETH, BNB as collateral, following an over-collateralization mechanism (usually requiring collateralization ratios ≥150%). Users can borrow an equivalent amount of USD1 stablecoins. This platform’s TVL once reached $4.3 billion, indicating it has gained significant trust.

Comparing the yield data: a leading exchange’s stablecoin financial product offers an annualized return of about 20%. This creates a clear interest spread—lending costs 1%, investment yields 20%, leaving about 18% as net profit. For example, with 1 BTCB, based on current market prices, collateralization allows borrowing an equivalent USD1, with an annual financing cost of just 1%, while the returns can cover costs and generate substantial profit.

From a risk perspective, this operation is much more stable than direct trading. You’re collateralizing mainstream blue-chip assets, lending out stablecoins, and investing in officially recommended financial products—each step is traceable. As long as the collateralization ratio stays above a safe threshold, there’s no risk of forced liquidation.

The actual process is straightforward, generally completed in about three steps. First, log into the lending platform, select BTCB, ETH, or BNB as collateral, deposit the required amount according to the system’s over-collateralization requirements. The platform uses real-time oracle prices to automatically calculate your borrowing limit. Second, choose to borrow USD1, the system will display a 1% interest rate, confirm the terms, and complete the loan; funds are directly transferred to your wallet. Third, transfer the borrowed USD1 to an exchange, find the corresponding yield product in the financial section, select the 20% annualized option, lock in the period, and then sit back and collect the returns.

The entire process from start to locking in the financial product generally takes less than 10 minutes. Liquidity is flexible—if you want to exit early, you can unlock the financial lock at any time, convert back to stablecoins, repay the loan, and redeem the collateral assets. The whole chain is transparent.

The beauty of this arbitrage model is that it activates idle blue-chip assets, allowing them to participate in generating returns while maintaining safety. No frequent trading or constant market monitoring is needed; assets can grow steadily. For users holding blue-chip coins who want to reduce risk, this indeed opens up a new approach.
