How Vaultie works
Vaultie is an overcollateralized lending service for bonded Pump.fun tokens on Solana. You pledge tokens, draw SOL against them, and reclaim them by repaying with interest — without ever selling. The sections below cover the full mechanics and, just as importantly, where the trust sits.
Overview
Lock your tokens at a dedicated address and a SOL credit is sent straight back to the wallet you sent from. Repay credit plus 5% interest to unlock your tokens. If the price falls far enough, the position is liquidated and you walk away owing nothing. There is no app to install and no connection to approve — the deposit itself is the action.
Loan lifecycle
A position moves through a handful of stages:
- Look up. Paste a bonded token address; Vaultie reads its live price and pool depth and shows what you can draw.
- Quote. Enter an amount and see the credit, interest, repay total and liquidation price up front — fixed at issue.
- Deposit. A one-time lock address is generated. Send your tokens to it from your own wallet (not an exchange).
- Disbursement. Once the deposit lands, the spot price is read again and the matching SOL is paid back to the sending wallet.
- Settlement. Repay credit × 1.05 any time to release your tokens, or let the position liquidate if the price halves.
Pricing & oracle
Collateral is valued from aggregated Solana DEX liquidity (Dexscreener / Jupiter). Because price is read across pooled venues, moving it enough to game a quote would mean moving the whole market — which the Smart Cap already makes uneconomical. Prices feed three things: the borrow quote, the live health of open positions, and the liquidation trigger.
Loan-to-value (LTV)
Standard 10%: you receive 10% of the locked token value as a SOL credit.
Boosted 15%: with ≥ 10,000,000 staked $VAULTIE your LTV rises to 15% — the core utility of the token.
Example: $400 locked → $40 credit standard, or $60 boosted.
Interest
The credit carries a single flat 5% (a starting value). Repayment is credit × 1.05 at any time — no compounding and no variable rate. Interest is the protocol's revenue, and a share is routed to the SOL liquidity providers who funded the loan.
Smart Cap
Across everyone, no more than 10% of a token's pool liquidity can be locked. At 10% LTV that caps total credit per token near ~1% of pool depth (1.5% with the boost). The effect: manipulation isn't worth it, and a forced sale barely dents the price. This is the core solvency mechanism.
Liquidation (50/50)
If spot falls 50% below the entry price, the position is liquidated automatically. The collateral is sold and the proceeds are split in half:
- Protocol half: clears the outstanding credit and interest first; anything left is profit.
- Borrower half: paid back to you. If the protocol half falls short, the borrower half is tapped — the credit is always covered first.
Staking
Supply SOL: provide liquidity to the credit pool and earn from loan interest. The APR is dynamic and rises with utilization.
Stake $VAULTIE: ≥ 10M staked $VAULTIE activates the 15% LTV boost on positions opened from that wallet.
Custody & trust
In this MVP, Vaultie is custodial / off-chain: a backend manages the lock addresses and the treasury, with no smart contract of its own. The frontend holds no keys; you simply send tokens and receive credit back. That means you are trusting the operator, not on-chain code. We don't dress this up — it's the single most important thing to understand before depositing.
Supported tokens
Currently bonded Pump.fun tokens only — those already migrated off the bonding curve to an AMM, where price and depth are reliable. Support for tokens still on the curve is planned once their pricing is robust enough to lend against safely.
