Project Description

Bunds is a novel DeFi primitive that solves the NFT liquidity crisis by transforming scattered, illiquid NFTs across multiple blockchains into unified, tradable ERC20 tokens. NFT owners lock their assets into Bond contracts and receive BondTokens sold on bonding curves (similar to pump.fun), providing instant ETH liquidity without selling their NFTs.

The protocol creates a sophisticated game theory ecosystem where:

  • Original owners can reclaim NFTs by buying back all BondTokens
  • Traders speculate on NFT value through BondToken trading
  • Fee vaults accumulate trading fees, creating dynamic price floors
  • Cross-chain asset concentration enables unprecedented liquidity density

Every token maintains intrinsic value through locked NFT collateral while accumulating trading fees in dedicated vaults. The system eliminates liquidation risks through permanent asset backing and establishes transparent price discovery through bonding curve mechanics.

"Bunds" addresses a $23B+ NFT market suffering from chronic illiquidity, enabling fractional ownership of collections while preserving cultural significance and eliminating the risks that plague existing solutions.

How it's Made

Built with a hybrid architecture combining Solidity smart contracts for bond creation and ERC20 tokenization, Next.js/TypeScript frontend for user interaction, and sophisticated bonding curve mechanics inspired by pump.fun. The protocol uses a modular design with configurable fee structures (default 2.5% trading fees), dual redemption systems (partial vault redemption and full NFT redemption), and cross-chain NFT locking capabilities.

Key technical innovations include the BondFactory contract for multi-collection bond support, bonding curve implementation with fee vault accumulation, and emergency functionality. The frontend integrates multi-wallet support, while the backend handles bond analytics and market dynamics.

The system creates multiple arbitrage vectors between fractionalized tokens, whole NFTs, and accumulated vault value, enabling sophisticated trading strategies. .
