Overview

What Vaultka actually does.

Vaultka is a leveraged-yield and lending protocol whose Solana deployment (V2) lets users borrow, lend, and run leveraged liquidity-provider strategies, with a primary focus on looping Jupiter's JLP (Jupiter Perpetuals LP) token. Depositors supply USDC to a lending pool to earn yield, while strategy users deposit collateral and the protocol automatically borrows from that pool, swaps into JLP via Jupiter, and loops the position using flash loans to reach up to 6.66x leverage in a single automated flow. JLP earns fees from Jupiter's perpetual DEX, and leverage amplifies that base yield net of USDC borrow costs. Positions are assigned a fixed maturity, and the protocol charges no deposit or withdrawal fees on its core vault. Vaultka originated on Arbitrum (strategies over GMX, GAINS, HMX, LEVEL and others) and governs via the VKA token. The protocol has been audited by Zokyo, Hacken, and Halborn, with bug bounties on Hats Finance and HackenProof.
