Self-Custody DeFi

Swap Without KYC. Earn Without Lockups.

Every exchange forces the same trade-off: to swap or earn, you give them your ID, your data, and control of your funds. Tangem changes that. Swap directly from your wallet using 8 integrated providers. Earn real yield on Aave without lockups. No KYC. No black box. No middleman. Just self-custody that actually works.

The Exchange Problem: KYC, Fees, and Hidden Risk

What Happens When You Swap on an Exchange

Step 1: Create account. Upload ID. Passport selfie. Proof of address. Hours of verification.

Step 2: They hold your funds in their wallet. You have an IOU.

Step 3: Swap. They take a cut from the spread (often hidden in the price).

Step 4: Withdraw. Subject to limits, withdrawal queues, and "maintenance windows."

Step 5: Your data is theirs. Today it's regulatory compliance. Tomorrow it's a data breach.

The real cost: Privacy gone. Data sold. Control surrendered. Risk concentrated in one company.

The Yield Trap

Exchanges promise 5-15% APY. How? They lend your funds to borrowers and pocket the difference. FTX promised yield. Celsius promised yield. BlockFi promised yield. All three went bankrupt.

You have no visibility into where your funds go. You're trusting their risk management. That trust has been wrong, repeatedly.

How It Actually Works

Swapping (3 Steps)

2. Compare rates. Tangem shows available providers for your route. You pick the best one.

3. Confirm. One tap. Done. Funds stay in your wallet the entire time.

Earning (Set and Forget)

1. Enable Yield Mode. Toggle it on. Funds auto-supply to Aave.

2. See your APY. Real rate from Aave borrowers. No platform markup.

3. Withdraw anytime. Tap withdraw. Funds back in your wallet. Instant.

Why Tangem's Approach Actually Matters

This isn't just "another wallet with swaps."

Multiple swap providers: Competition drives better rates. You win.
Hardware security option: Your Tangem card signs swaps. Keys are designed to remain on your device during signing workflows.
On-chain verification: See the Aave contract. Verify the rates. Trust math, not marketing.
Audited contracts: Tangem's smart contracts reviewed by security auditors. Aave TVL changes over time; verify current metrics before allocating funds.
Auto-compounding: Yield reinvests automatically. Passive income on autopilot.
No platform fees: You get the real Aave rate. Tangem takes nothing.

Who Should Use This

Privacy-conscious traders. Swap without giving up your ID.
Yield farmers paranoid about FTX-style collapses. Aave > centralized "earn" programs.
People tired of KYC friction. Swap, earn, and withdraw on your terms.
Hardware wallet users wanting DeFi. Sign swaps and yield deposits with your Tangem card.
Anyone who actually reads terms of service. "Withdrawals may be paused." Not on Aave.

The Bottom Line

Self-custody doesn't mean giving up trading or yield. Tangem proves you can have both.

Swap without KYC. Earn without lockups. Control your keys the entire time. This is what DeFi was supposed to be.

Swap and Earn on Your Terms

Multiple swap providers. Real Aave yield mechanics. KYC requirements vary by route and region. Verify current terms before use.
