Crash the price.Watch the layers work.

Your Health Factor is the height of your collateral (counted at its liquidation threshold) divided by your debt. Point at anything in the scene to see what it is. Then drag the ETH price or run a 3 a.m. crash, and switch layers off to see what happens without them.

The number that matters

Health Factor

Counted collateral divided by debt. Above 1.00 your loan is open; at 1.00 anyone can liquidate it and keep a penalty.

Tahansoe acts at your trigger (1.30), well before 1.00, and repays just enough to bring HF back to your target (1.60).

Health Factor: 1.66
Trigger / target: 1.30 / 1.60

HF 1.66

Not liquidated yet

Nothing has happened yet. Layers only act when HF drops below your trigger (1.30).

Illustrative numbers: 2 ETH collateral, $3,200 USDC debt, liquidation threshold 0.83, trigger 1.3, target 1.6. Real outcomes depend on gas, oracle updates, and market liquidity. Tahansoe lowers the odds of liquidation; it does not guarantee against it.

Collateral

The ETH you locked on Aave. Its value moves with the market, so when ETH falls, the cushion under your loan shrinks.

The problem

Liquidationhappens whileyou sleep

Health Factor: Collateral × liquidation threshold ÷ debt. Above 1 you're safe; below 1 you can be liquidated.
Liquidation: Bots repay up to half your debt and take your collateral plus a ~5–10% penalty.
The catch: Prices move at 3 a.m. too. Most liquidations happen when nobody is watching.

Three layers, checked in order

Three wallsbetween your loanand liquidation

Each layer is a permission you grant yourself, with its own cap. Tahansoe always tries the cheapest one first and only moves to the next if it can't restore your Health Factor.

L1 · Wallet reserve L2 · Position reserve L3 · Flash deleverage

Your position

Your Aave loan. When its Health Factor falls below your trigger, Tahansoe tries the walls in order, cheapest first.

Your wallet

USDC you keep in your own wallet. You approve a capped amount; it stays yours and untouched until HF hits your trigger.

Layer 1 · Wallet reserve

Repay from theUSDC in your wallet

The first and cheapest line of defence. You set aside a capped amount of the token you borrowed, and Tahansoe uses it to pay down your debt the moment your Health Factor hits your trigger.

You approve: USDC (your debt token), up to a cap you choose
Runs when: HF < trigger and your wallet holds USDC
Cost: Gas only
You keep control: Funds stay in your wallet until needed. Revoke anytime.

Vault shares

Another DeFi position you already hold, like a Morpho vault or an Aave aToken. It keeps earning yield until it is needed.

Layer 2 · Position reserve

Then draw fromanother position

If your wallet runs dry, Tahansoe redeems shares from another DeFi position you already hold, like a Morpho Vault or an Aave aToken, and uses the proceeds to repay.

You approve: Vault shares (ERC-4626) or aTokens, up to a cap
Runs when: HF < trigger and Layer 1 can't cover it
Cost: Gas, plus any vault exit fee
You keep control: Your position keeps earning until it's used. Revoke anytime.

① Flash loan

USDC is borrowed for the length of a single transaction. No reserve of your own is needed.

Layer 3 · Flash deleverage

Last resort:deleverage in one step

When there's no reserve left and HF keeps falling, a flash loan repays part of your debt and just enough collateral is swapped to close it. Everything happens in a single transaction, or nothing does.

You approve: Your collateral aToken (e.g. aWETH), up to a cap
Runs when: HF < trigger and Layers 1 & 2 are empty
Cost: ~0.05% flash fee + swap slippage (max you set)
You keep control: Opt-in only. Atomic: if any step fails, nothing moves.

Why Tahansoe

Tahansoe vs typical automation

An honest comparison: Tahansoe vs typical automation (e.g. DeFi Saver).

Parameter	Typical automation (e.g. DeFi Saver)	Tahansoe3-Layer Defense
How a position is saved	DeFi Saver repays by selling collateral via a swap.	Uses 3 layers: wallet stablecoins (L1) → vault reserve (L2) → sell collateral only if needed (L3), keeping ETH exposure.
Fee	0.05% automation fee + 0.25% swap fee (ETH→USDC) + gas charged to the position.	0.15% only when we actually save you (HF below your own trigger), free otherwise; early actions by the risk agent are free; L1/L2 need no swap.
Minimum debt	$500 on Arbitrum ($30k on mainnet).	None.
Trigger	Static thresholds.	Can be raised early by the risk agent, only within your band.

Two agents

Two agentskeeping watch

Research run

Every 1–2 hours the agent reads prices, lending rates, liquidity, macro data and news, then writes one short risk brief.

Agent 1 · Market Pulse

One research run,every subscriber

What it does: Reads market data (prices, lending rates, liquidity) and writes one short brief.
How often: Once per cycle. The same brief goes out to everyone who turned it on in Telegram.
Never: Makes up numbers or touches your position. Figures come from data, not the AI.

HF Sentinel

Watches the Health Factor of every protected position around the clock, so you don't have to.

Agent 2 · HF Sentinel

Watches your HF,rules pull the trigger

What it does: Checks your Health Factor around the clock and tells you which zone you're in.
When it acts: Below your trigger, a fixed rule runs Layer 1 → 2 → 3. The AI explains why HF dropped.
Never: Signs transactions or changes your settings. AI explains, rules execute.

AI explains · Rules execute · AI never signs

How it works

Set up in four steps

Step 1 · Connect

Sign-In with Ethereum: one signature, no password, no email, and no transaction.
Tahansoe reads your public Aave position (collateral, debt, Health Factor). Nothing is moved.

FAQ

Questions

Does Tahansoe hold my funds?

No. You approve capped allowances to the contract, and it can only use them to repay your own Aave debt. You can revoke them at any time.

When does a layer run?

When your Health Factor falls below the trigger you set (for example 1.30). Layer 1 runs first, then Layer 2, and Layer 3 only if the first two are not enough.

Can the AI move my money?

No. Execution follows fixed rules. The agents only explain what is happening and send you briefs on Telegram.

Is liquidation impossible then?

No. A sudden crash, oracle lag or congestion can move faster than any keeper. Tahansoe lowers the risk; it does not remove it. Not financial advice.
