🔷 What is ERC1155?

ERC1155 is a multi-token standard. It allows a single smart contract to manage multiple types of tokens — both fungible (like ERC20) and non-fungible (like ERC721) — in a single contract.

🔸 Key Concepts:

Feature ERC20 ERC721 ERC1155
Token Type Fungible Non-Fungible Both
Separate Contract per Token ✅ Yes ✅ Yes ❌ No (one contract for all)
Batch Transfer ❌ No ❌ No ✅ Yes
Gas Efficiency Medium Low ✅ High

🔷 Why is ERC1155 Useful?

  1. Unified Token Management: One contract can hold many token types (like coins, weapons, skins).
  2. Batch Transfers: Send multiple token types to multiple recipients in a single transaction.
  3. Gas Efficiency: Reduces deployment and execution cost.
  4. Better Game/Metaverse Support: Good for managing items like swords (fungible), shields (fungible), or unique NFTs (non-fungible).
  5. Simplifies Smart Contract Logic: Avoids writing new contracts for each item or token.
