ERC-1155: Multi Token Standard
More gas-efficient than deploying separate ERC-20 + ERC-721 contracts. Standard for gaming, semi-fungible assets, and multi-edition NFTs.
What It Defines
Combines fungible and non-fungible tokens in a single contract. Supports batch transfers, reduces gas costs, and allows one contract to manage many token types (e.g., game items, mixed asset portfolios).
Canonical (Normative)
Convenient (Practical)
The Ethereum community's open process for proposing changes to the protocol. EIPs cover core protocol changes; ERCs (Ethereum Request for Comments) cover application-layer standards like token interfaces.
