Features

Staking System for Fee Distribution

Users can stake meme tokens to earn trading fees from a DAMM v1 pool. Only the top stakers (configurable number) receive fee distributions. The program maintains a top staker list and a full balance list to track all participants.

Vault Initialization

Creates a vault associated with a specific AMM pool (Dynamic AMM) with configurable parameters:
  • top_list_length: Number of top holders who receive fees (min: 10, max: 300)
  • seconds_to_full_unlock: Time for locked fees to be fully distributed (min: 60s, max: 30 days)
  • unstake_lock_duration: Lock period for unstaking (min: 1 hour, max: 30 days)
  • start_fee_distribute_timestamp: When fee distribution begins

Staking Operations

  • Stake: Users deposit meme tokens to participate in fee sharing
  • Initialize Stake Escrow: Creates an escrow account for each staker
  • Automatic tracking of stake amounts and positions in the top holder list

Fee Claiming Mechanism

Claims fees from the associated DAMM v1 pool with:
  • Dual token fees: Supports both base (meme) and quote (SOL/USDC) tokens
  • Auto-restaking: Claimed meme tokens are automatically restaked
  • Quote token withdrawal: Only quote tokens (SOL/USDC) are sent to users
  • Fees distributed proportionally based on stake amount among top holders
  • Time-locked fee release mechanism for gradual distribution

Unstaking Process

  • Request Unstake: Initiates unstaking with a lock period
  • Cancel Unstake: Allows cancellation before the lock period ends
  • Withdraw: Complete withdrawal after the lock period expires
  • Maintains ongoing_total_partial_unstake_amount to track pending unstakes

Dynamic Top Holder Management

  • Automatically updates the top staker list when stakes change
  • Tracks whether a staker is in the top list (in_top_list flag)
  • Adjusts fee distribution checkpoints when users enter/exit the top list

Fee Distribution Algorithm

  • Uses a checkpoint system with cumulative fee per liquidity
  • Calculates pending fees based on stake amount and time in the top list
  • Supports gradual fee release over seconds_to_full_unlock period

Permissionless

  • Claim Fee Crank: Anyone can trigger fee claims from the AMM pool
  • Helps ensure regular fee collection even if users don’t claim
