Provide Liquidity (Lend)
Deposit TON and earn interest income. You have full control over the terms — which collections to accept, at what rate, and for how long.
How to Become a Lender
1. Connect Your Wallet
Connect a TON wallet via TonConnect or Telegram Mini App.
2. Create a Strategy
Go to the Earn page and configure lending terms:
- Collections — which NFTs you're willing to accept as collateral
- Loan amount — how much TON to lend per NFT
- Interest rate — annual rate (your income)
- Duration range — minimum and maximum loan term
Don't want to configure manually? Choose a ready-made preset:
| Preset | LTV | APY | Duration | Description |
|---|---|---|---|---|
| Conservative | 45% | 40% | 7-14 days | Low risk: loan amount well below NFT value |
| Balanced | 60% | 60% | 7-14 days | Balance of risk and yield |
| High Yield | 75% | 80% | 7-14 days | High yield, but higher risk if NFT price drops |
3. Create Your Liquidity Vault
On first use, the protocol creates your personal liquidity vault on the blockchain. This happens once.
4. Fund Your Vault
Transfer TON to your vault. These funds will be available for issuing loans.
5. Publish Your Strategy
After publishing, borrowers will see your offer and can take loans on your terms. The strategy supports multiple loans — as long as there's available liquidity in the vault. Publishing costs ~0.01 TON (network fee).
Liquidity Management
Balances
Your vault has two balance types:
| Type | Description | Withdrawable? |
|---|---|---|
| Free balance | Funds available for new loans | Yes, at any time |
| Reserved balance | Funds tied to active loans | No, until the loan is complete |
Top-up
You can fund your vault at any time. Funds become immediately available for new loans.
Withdrawal
Free balance can be withdrawn fully or partially at any time. What happens to reserved funds depends on the loan outcome:
- Repayment — principal + 90% of interest return to free balance
- Default — the funds are already with the borrower and will not be returned; you get the collateral NFT instead
How Income Is Calculated
You receive 90% of interest on every loan. The remaining 10% is the protocol's service fee.
Example:
| Parameter | Value |
|---|---|
| Loan amount | 100 TON |
| Annual rate | 36.5% |
| Duration | 7 days |
| Interest for 7 days | 100 x 36.5% x 7/365 = 0.70 TON |
| Your income (90%) | 0.63 TON |
| Protocol fee (10%) | 0.07 TON |
If the borrower repays early, interest is calculated proportionally to the actual usage period.

Default: What If the Borrower Doesn't Repay
If the loan term expires and the borrower hasn't repaid:
- Go to the loan management page
- Find the overdue loan (status Overdue)
- Click Claim Default
- Attach TON for gas and service fee (10% of interest)
- The NFT will be transferred to your wallet
What You Receive on Default
- The borrower's collateral NFT — this is your compensation
- The principal is not returned — the TON stays with the borrower; you get the NFT instead
- You don't receive interest
- Default economics: profitable when the NFT is worth more than the principal (typically the case — NFTs are accepted at 45–75% LTV)
Changing Your Strategy
You can update your strategy at any time:
- Add collections — expand the list of accepted NFTs
- Change terms — amount, rate, duration range
- Delete strategy — stop accepting new loans
Changing the strategy doesn't affect already active loans — their terms are fixed.
FAQ
Can I lend to multiple collections at once?
Yes. A single strategy can include terms for different collections with different parameters.
What if I run out of TON?
When the free balance reaches zero, no new loans will be issued. Active loans continue to work. Fund your vault to resume lending.
Can I close my vault?
You can withdraw the entire free balance and delete your strategy. The vault will stop accepting new loans.
How often do I need to check the app?
Active loans don't require your participation — everything is automated. The only action requiring your involvement is claim default for overdue loans.
Is this safe?
Your funds are stored in your personal vault on the blockchain. Only you can withdraw the free balance. Funds are issued to borrowers only according to your strategy terms, verified cryptographically.
