Examples › Lending and borrowing

Lending and borrowing, explained before you sign

A deposit into a lending market and a transfer to a stranger look the same in a balance preview: tokens leave your wallet. SignLens names the market, what the tokens become (collateral, a loan, a repayment) and which account they reach.

Deposit USDC into Kamino Lend

A balance preview shows 4,635.28675 USDC leaving. SignLens says where it goes, Kamino Lend, and what it becomes: collateral credited to the obligation, the account that records what you have deposited and borrowed. The reserve refreshes are named as what they are, housekeeping that moves nothing.

Open a leveraged position with a Jupiter Lend flash loan

Four steps in one transaction: borrow USDC for the length of the transaction, swap it for sUSDai, deposit the sUSDai as collateral and borrow USDC against it, then repay the flash loan. A balance preview nets this out to almost nothing; SignLens lists every step, and every transfer in and out of your accounts.

OK
