Metropolis / liquidity-book-vaults

Maker Vault Code Introduction: Maker Vaults are fully on-chain, non-custodial smart contracts that deploy and manage liquidity into DLMM pools. Managed by wallets, these vaults simplify liquidity provisioning while ensuring transparency.

Core Features:

• Open for All: Create and manage an own vault with a one-time creation fee of 400 $S.
• 1-Click Participation: Users can join existing vaults effortlessly, eliminating the complexity of adjusting positions to market volatility.
• Earnings for Vault Operators: Vault operators set an AUM fee (0.5%–10%) for their services.
• Earnings for Vault Participants: Vault participants earn all the trading fees and farming rewards. Trading Fees are auto-compounded and rewards like Metro need to be claimed.

Vault operators have full control to adjust DLMM positions and use the built-in reserve to strategically park unallocated funds. However, they never have direct access to the funds themselves, which are held by the smart contract.
