Overview
Dev Bank is a launchpad-bank for Pump.fun memecoins on Solana. It combines two products under one balance sheet:
- Mirror loans — devs deposit N SOL and receive an equal-sized loan, repaid automatically from creator fees.
- Lending pool — anyone can deposit SOL to fund mirror loans and earn boosted SOL rewards.
Both flows feed a shared profit pool, 70% of which is paid to $DEV holders every 2 hours in SOL. The rest goes to buyback, insurance, and protocol treasury.

Underwriting gates
To qualify for a mirror loan, a coin must pass:
- Token age
≥ 6 hours - 24h volume
≥ 5 SOL - Holders
≥ 50 - Top-10 concentration
≤ 60% - DEX liquidity
≥ 2× requested loan - Honeypot check passed (sell simulation succeeds)
Default & liquidation
If the loan is not repaid by the end of the grace period:
- Day 0–N (grace). Fees auto-repay. Nothing else happens.
- Day N+30 (soft default). Loan flagged. Fee-receiver remains on bank until any value is recovered.
- Day N+60 (liquidation). Locked supply is sold via TWAP on Raydium. Proceeds cover remaining debt; surplus → insurance fund.
The dev's deposit and any accrued fees are claimed first; locked supply is sold only if those don't fully cover the remaining debt.
