Constant product AMM implementing x*y=k formula
A decentralized exchange protocol allowing users to provide liquidity, swap tokens, and earn fees.
Key Features:
- Liquidity pool initialization with dual tokens
- Add/remove liquidity with LP token minting/burning
- Token swaps with configurable fee structure
- Slippage protection mechanisms
- Authority-controlled pool locking
Smart Contract Highlights:
- Uses
constant-product-curvelibrary for calculations - PDA-based vault accounts for token storage
- LP token minting for liquidity providers
- Fee distribution to liquidity providers
On-chain dice game with provably fair randomness
Implements a betting system where players can place bets on dice rolls with verifiable randomness using Ed25519 signatures.
Key Features:
- Place bets with customizable roll predictions (2-96)
- Provably fair randomness using Ed25519 signatures
- House edge mechanism (1.5%)
- Automatic payout calculation
- Refund system for expired bets
- Timeout protection (1000 slots)
Security:
- Ed25519 signature verification for randomness
- House-signed message validation
- Time-based bet expiry
- Secure vault management
Trustless token swap escrow system
Enables peer-to-peer token swaps without requiring trust between parties, with full refund capabilities.
Key Features:
- Maker initiates escrow with token A deposit
- Taker completes swap by providing token B
- Maker can refund if deal expires
- Supports SPL tokens and Token-2022
- Atomic swap execution
- PDA-based vault security
Use Cases:
- OTC (Over-The-Counter) trades
- NFT-for-token swaps
- P2P trading without centralized exchange
