Introducing bsxUSD

The Base-native money lego for traders

Capital Efficiency, Reimagined

At BSX, we believe capital efficiency isn’t just about how much leverage you can get — it’s about how well your capital works for you. That’s why we’re excited to launch bsxUSD, a yield-generating stablecoin built for traders, powered by real onchain yield, and fully integrated into BSX’s leveraged trading ecosystem.

With bsxUSD, your USDC doesn’t sit idle. It earns passive yield when you’re not trading — and becomes 50x leverage-ready collateral when you are.

💡 Why bsxUSD?

Over $4B USDC sits idle on across Base, most not earning a single dollar in yield. That’s ~$10M if not $100M/year in missed opportunities.

We built bsxUSD to fix that.

bsxUSD turns your USDC into a productive asset:

• Dual-Purpose USD: Put your dollar to work in two ways — earn yield and use it as trading collateral simultaneously. No need to choose between lending markets and trading opportunities.

• Automatically Build Account Equity: Yield earned through bsxUSD is added directly to your account equity, helping you grow your portfolio while providing an extra buffer against liquidation.

• Compounded Earnings: bsxUSD automatically compounds your yield over time, so you can set it and forget it.

• 100% 1:1 Conversion Rate: You can convert bsxUSD 1:1 for USDC at any time.

• Instant Redemption: Redeem bsxUSD for USDC instantly — with no fees and no lockups.

• Boost Your PnL: bsxUSD enhances your profitability regardless of your trading strategy by growing your account equity passively.

• Earn BSX Rewards: Holding bsxUSD earns you additional BSX incentives — with the potential for even more protocol rewards in the future.

🔗 Composability with @MorphoLabs

bsxUSD is composable by design — we partnered with Morpho to optimize USDC yield across top-tier lending protocols on Base.

It rebalances dynamically using predictive onchain data to seek the best returns — no active management required.

Audited by Halborn, bsxUSD is secure, composable money designed for modern DeFi use.

How It Works: Yield earning, Simplified

Earning yield with bsxUSD is easy. You just have to deposit it into the BSX Prime Collateral vault. Below are the steps:

• Deposit USDC: Start by depositing USDC into the BSX platform.

• Convert to bsxUSD: Your USDC is instantly converted to bsxUSD at a 1:1 ratio — no slippage, no fees.

• Earn Yield: Once converted, bsxUSD automatically generates passive, compounding yield through Prime Collateral.

• Redeem Anytime: Need access to your funds? Redeem bsxUSD back to USDC instantly — no waiting, no fees.

bsxUSD Prime Collateral Mechanism

What’s next

Before bsxUSD, we introduced the Liquidation Vault — a vault product with a different mechanism but the same mission: to maximize capital efficiency and deliver long-term value to traders.

With bsxUSD, we’re starting by unlocking passive yield on USDC, but this is just the beginning. We’re building towards a broader, more composable Prime Collateral ecosystem with expanded utility and functionality:

• Cross-Chain Deposits: Seamlessly deposit USDC from other chains directly into bsxUSD.

• On-Ramp Integration: Fund bsxUSD via ACH, credit card, or directly from centralized exchanges.

• Multi-Asset Support: Earn yield on a range of collateral types — not just USDC — while using them to trade on BSX.

• Dynamic Yield Optimization: bsxUSD will continuously rebalance across leading lending protocols to find the best returns.

The future of DeFi collateral is capital-efficient, composable, and always working for you — and bsxUSD is leading the way. bsxUSD is a foundational building block for the next generation of capital-efficient DeFi on Base.
