What Stablecoins Can I Earn Yield On with Sats Terminal?

What Stablecoins Can I Earn Yield On with Sats Terminal?

Stablecoins are one of the most popular assets for yield generation in crypto. Their price stability makes them ideal for earning passive income without the volatility risk associated with Bitcoin or other cryptocurrencies. Sats Terminal's Earn product supports two major stablecoins: USDC and USDT.

This guide covers which stablecoins are supported, how yield is generated, the differences between USDC and USDT vaults, and a strategy for combining Borrow and Earn to maximize your returns.

Supported Stablecoins

USDC (USD Coin)

USDC is issued by Circle and is one of the most widely used stablecoins in DeFi. It is fully backed by cash and short-term U.S. Treasury bonds, with regular third-party attestations verifying its reserves.

Key characteristics:

• Issuer: Circle (in consortium with Coinbase)
• Peg: 1 USDC = 1 USD
• Backing: Cash and U.S. Treasury securities
• Transparency: Monthly reserve attestations by Grant Thornton
• Regulatory stance: Circle is a regulated financial services company

USDC is widely regarded as one of the safest stablecoins due to its transparent reserves and regulatory compliance. It is the most commonly used stablecoin in DeFi lending and yield strategies.

USDT (Tether)

USDT is issued by Tether Limited and is the oldest and largest stablecoin by market capitalization. It is backed by a reserve of cash, cash equivalents, and other assets.

Key characteristics:

• Issuer: Tether Limited
• Peg: 1 USDT = 1 USD
• Backing: Cash, cash equivalents, secured loans, corporate bonds, and other investments
• Transparency: Quarterly reserve reports
• Market position: Largest stablecoin by market cap and trading volume

USDT has the deepest liquidity of any stablecoin, making it widely accepted across both DeFi and CeFi platforms. Its reserve composition has been a subject of scrutiny, but it has consistently maintained its peg.

How Stablecoin Yield Is Generated

Stablecoin yield comes from several sources, depending on the vault strategy:

Lending

The most straightforward source of stablecoin yield. When you deposit USDC or USDT into a lending vault, your assets are made available to borrowers through a lending protocol. Borrowers pay interest on their loans, and that interest is distributed to depositors proportionally.

Stablecoin lending is a core function of DeFi. Borrowers want stablecoins for a variety of reasons:

• Leveraged trading — Borrow stablecoins to buy more crypto, amplifying exposure.
• Operational expenses — Projects and DAOs borrow stablecoins for salaries, expenses, and development.
• Avoiding taxable events — Borrow against crypto holdings instead of selling (and triggering capital gains).
• Arbitrage — Borrow stablecoins to exploit price differences across platforms.

The demand for stablecoin borrowing drives the supply rate — when demand is high, yields increase; when demand is low, yields decrease. This makes stablecoin lending yields inherently variable.

Liquidity Provision

Stablecoins are often paired in stablecoin-to-stablecoin liquidity pools (e.g., USDC/USDT) or in pools pairing a stablecoin with another asset. Depositors earn a share of trading fees generated by the pool.

Stablecoin-to-stablecoin pools have a unique advantage: since both assets are pegged to the same value, impermanent loss is minimal. This makes LP-based stablecoin vaults less risky than LP strategies involving volatile assets.

Aggregated Yield Across Supported Platforms

Earn aggregates stablecoin yield across its supported platforms and automatically routes deposits to the most competitive rate available at deposit time. Specific underlying providers and venue types are not disclosed in the public docs; rate behavior depends on the underlying platform mix at any given moment.

Protocol Incentives

Some vaults benefit from additional yield in the form of governance token rewards from the underlying protocols. These rewards are typically sold and compounded back into the vault, boosting the effective APY.

Stablecoin Yield Rates: What to Expect

Stablecoin yields fluctuate with market conditions. Here is a general framework:

Low-Demand Periods (Bear Market)

During periods of low borrowing demand, stablecoin lending rates tend to compress. Typical yields might range from 2-5% APY. Liquidity provision yields also tend to be lower as trading volumes decline.

High-Demand Periods (Bull Market)

When borrowing demand surges — typically during bull markets when traders want leverage — stablecoin yields can increase significantly, potentially reaching 8-15% APY or higher during peak demand periods.

Comparing USDC vs. USDT Yields

Yields between USDC and USDT vaults are generally similar, since both stablecoins serve comparable roles in lending and liquidity markets. However, slight differences can occur:

• USDT sometimes offers marginally higher yields because some protocols price in a small risk premium for USDT's less transparent reserves.
• USDC may offer slightly lower yields but is preferred by risk-averse depositors due to its regulatory standing and reserve transparency.

Check the Earn dashboard for current rates — the difference between USDC and USDT yields at any given time is usually small.

How Earn Handles Stablecoin Deposits

When you deposit USDC or USDT into Earn, the aggregator compares yield options across supported platforms and routes your deposit to the most competitive rate available at the time. You do not manually pick a vault tier — Earn handles the venue selection, along with any required bridging and wrapping, automatically.

• Risk: Low (smart contract risk only)
• Yield: Moderate, tracks borrowing demand
• Best for: Long-term, passive earning

Optimized Lending Vaults

Similar to conservative lending but with added optimization — the vault may rotate between multiple lending protocols to capture the best available rate, and auto-compounds earned interest.

• Risk: Low to moderate (multi-protocol smart contract risk)
• Yield: Slightly higher than single-protocol lending
• Best for: Users wanting better rates without significantly more risk

Stablecoin Liquidity Vaults

These vaults provide liquidity to stablecoin trading pairs on DEXs. Since both sides of the pair are pegged to USD, impermanent loss is minimal.

• Risk: Low to moderate (smart contract risk, minimal impermanent loss)
• Yield: Moderate, driven by trading volume
• Best for: Users comfortable with LP mechanics

Structured Stablecoin Vaults

More complex strategies that combine lending, liquidity provision, and other instruments. These vaults aim for the highest risk-adjusted returns but involve more moving parts.

• Risk: Moderate (multiple protocol dependencies)
• Yield: Higher potential
• Best for: Experienced users

Risk Comparison: USDC vs. USDT

While both stablecoins are generally stable, they carry different risk profiles:

Depeg Risk

A depeg event occurs when a stablecoin loses its 1:1 peg to USD. Both USDC and USDT have experienced brief depeg events:

• USDC briefly depegged in March 2023 when Silicon Valley Bank (which held a portion of Circle's reserves) collapsed. The peg was restored within days.
• USDT has experienced minor, short-lived deviations from its peg during periods of market stress but has never experienced a sustained depeg.

Depeg risk is generally considered low for both stablecoins but is a factor to be aware of.

Regulatory Risk

• USDC is issued by a U.S.-regulated entity, which provides some assurance but also means it could be affected by U.S. regulatory actions (e.g., address blacklisting).
• USDT operates in a more ambiguous regulatory environment, which creates different risk considerations.

Reserve Transparency

• USDC publishes monthly attestations of its reserves.
• USDT publishes quarterly reports but has faced criticism for the composition and transparency of its reserves.

Smart Contract Risk

The smart contract risk for both stablecoins is primarily associated with the vault contracts, not the stablecoin contracts themselves. This risk is the same regardless of which stablecoin you deposit.

The Borrow-Then-Earn Strategy

One of the most powerful features of the Sats Terminal ecosystem is the ability to combine the Borrow and Earn products. Here is how it works:

Borrow aggregates BTC-backed borrow offers and returns the lowest available rate, while Earn aggregates stablecoin and BTC yield opportunities and auto-routes to the most competitive rate at deposit time. Pairing them lets you keep your BTC exposure (via Borrow) and earn on the resulting stablecoins (via Earn) without actively shopping venues yourself on either side.

The Concept

1. Deposit BTC as collateral using Sats Terminal's [Borrow product](/borrow/faq/what-stablecoins-can-i-borrow-on-sats-terminal).
2. Borrow USDC or USDT against your BTC.
3. Deposit the borrowed stablecoins into an Earn vault.
4. Earn yield on the borrowed stablecoins while maintaining your BTC exposure.

When This Strategy Is Profitable

This strategy is profitable when the yield you earn on your stablecoins exceeds the interest rate you pay on your loan. For example:

• You borrow USDC at 5% APR
• You deposit that USDC into a vault earning 8% APY
• Your net yield is approximately 3% (8% earned minus 5% paid)

Risks to Consider

• Liquidation risk — If BTC's price drops, your loan could be liquidated. Monitor your loan-to-value (LTV) ratio carefully.
• Rate risk — If borrow rates increase or earn rates decrease, your net yield could turn negative.
• Compounding costs — Borrow interest accrues regardless of whether your earn vault is performing well.

This strategy is best for users who understand both products and can actively monitor their positions.

Example Scenario

Let's say you have 1 BTC and want to earn yield without selling it:

1. Deposit 1 BTC as collateral on Borrow.
2. Borrow $30,000 USDC at a conservative LTV (e.g., 50% of your BTC's value).
3. Deposit the $30,000 USDC into a lending vault earning 7% APY.
4. Over one year, you earn approximately $2,100 in yield.
5. Subtract your borrow interest costs for your net profit.

Meanwhile, you still own your 1 BTC and benefit from any price appreciation.

Maximizing Stablecoin Yield

Diversify Between USDC and USDT

Splitting your stablecoin deposits between USDC and USDT vaults reduces your exposure to either stablecoin's specific risks (depeg, regulatory action, etc.).

Take Advantage of Rate Fluctuations

Stablecoin yields fluctuate with market conditions. During high-demand periods, yields spike. Having stablecoins ready to deploy into vaults during these periods can significantly boost your returns.

Use Auto-Compounding Vaults

Auto-compounding vaults reinvest your earned yield automatically. Over time, the compounding effect meaningfully increases your total returns compared to vaults that distribute yield as a separate balance.

Monitor Vault Performance

Even stable strategies can see rate changes. Check your vault's performance periodically and consider switching if a materially better opportunity emerges.
