# ERC-721

## Definition

ERC-721 is an Ethereum standard for non-fungible tokens in which individual token IDs represent distinct assets or records.

## What it means in practice

Ownership and transfer rules are maintained by the NFT contract, while metadata may be on-chain or externally referenced.

## How this concept appears in Terenval Wallet

If Terenval interacts with an ERC-721 contract through a supported dApp flow, the wallet signs a contract transaction rather than a native-coin transfer.

**Important:** NFT signature requests can still grant approvals or transfers, so verify the exact contract and action.
