# ERC-1155

## Definition

ERC-1155 is an Ethereum multi-token standard that allows one smart contract to manage multiple fungible, non-fungible or semi-fungible token IDs.

## What it means in practice

The standard can batch transfers and approvals across multiple token IDs.

## How this concept appears in Terenval Wallet

When a supported dApp requests an ERC-1155 action through Terenval, treat it as a smart-contract permission or transfer request.

**Important:** Review operator approvals carefully because one permission can affect multiple token IDs.
