Time Locked Yield

Time-Locked Yield NFTs

Overview

This project lets users provide liquidity to a Raydium pool and lock their LP tokens into NFTs that can't be withdrawn until a future time.

The longer users lock their tokens, the more swap fees they earn.

This works like a DeFi savings bond.

Features

• Add liquidity to Raydium pools
• Lock LP tokens as NFTs with metadata
• Set a time lock to prevent early withdrawals
• Earn higher fees for longer lock periods
• Withdraw or collect fees only after the lock period ends

Why This Project Stands Out

• Combines DeFi (Raydium) and NFTs (Metaplex-style tokens)
• Uses time-locks for real incentives
• Encourages long-term liquidity

How It Works

1. Create or Select a Pool

• Use Raydium program via Neon EVM precompile.
• Choose an existing pool or create one.

2. Add Liquidity

• Call addLiquidityInstruction using Raydium logic.
• LP tokens are minted to the user.

3. Lock Liquidity as NFT

• Call lockLiquidityInstruction.

• LP tokens are burned and represented as a locked NFT.

• Metadata includes:

  • lock_until: timestamp when it can be unlocked
  • initial_amount: original LP token amount
  • bonus_rate: % of extra fee reward for time commitment

4. Prevent Early Unlock

• NFT metadata is tracked in a Solidity contract.
• If block.timestamp < lock_until, collectFeesInstruction or withdrawLiquidityInstruction fails.

5. Collect Fees

• After the lock period ends, users can:

  • Call collectFeesInstruction to get their fee share
  • Or use withdrawLiquidityInstruction to remove their liquidity
