A vault takes your deposit, gives you a share token and runs the strategy for you. JewelSwap runs two USDC vaults on Sui. One lends USDC to the best-paying lender. The other loops Ember's eEARN with borrowed USDC for a higher, riskier yield.
The same deposit coin, two different risk levels. Rates move daily, so the app shows them live instead of this page.
Both vaults follow the same pattern. Only the strategy differs.
The contract mints you a share token. Its value is your slice of the vault's assets.
A JewelSwap bot moves funds or adjusts the loan inside limits the contract enforces. It cannot send vault funds anywhere else.
Burn your share token and get your slice back in USDC, after any exit fee.
Pick the USDC Vault. It earns what Sui lenders pay on USDC, spreads it across three of them and never takes a loan.
Pick Ember Loop. It earns more when eEARN pays well above the borrow rate and loses faster when it doesn't.
A smart contract that pools deposits of one coin, runs a set strategy with them and gives each depositor a share token. The share token is worth a growing amount of the deposit coin as the strategy earns. You don't move funds between protocols or claim rewards yourself.
The USDC Vault. It only lends USDC and never borrows, so it cannot be liquidated. Ember Loop borrows against eEARN to raise the yield, which also raises the loss if eEARN falls or borrowing gets expensive.
In the USDC Vault, from interest that borrowers pay NAVI, Scallop and Suilend. In Ember Loop, from eEARN's yield on the whole position minus the interest on the borrowed USDC.
Yes. They are separate contracts with separate share tokens, jcUSDC and jeLOOP, and both take USDC on Sui.
Not externally yet. Both have had internal reviews. The USDC Vault is capped at 10,000 USDC while it is new. Only deposit what you can afford to lose.
