# Common

Below you can find out which methods mean what

### General

**getName**: Name of the relevant asset

**getSymbol**: Symbol of the relevant asset

**getBalance**: Asset balance at the wallet address sent as a parameter

**getDecimals**: The decimal value of the respective asset applies to this Coin and Token. For NFT it is always 0 and does not have to be in every contract.

**transfer**: Initiates a transfer transaction that can be signed by the owner of the relevant asset

### Contracts

The methods here do not have to be in every contract. Only standard asset contracts on blockchain networks have them.

**approve**: Executes a transaction that allows the asset to be managed and spent by another wallet

**transferFrom**: Executes the transaction by which the asset can be transferred to any other wallet by the wallet address authorized by "approve"

### NFT

**getApproved**: Checks whether the relevant NFT is authorized to spend to any other wallet

**getTokenURI**: Returns the URL address where the metadata of the relevant NFT is located

**getOwner**: Returns the wallet address of the owner of the relevant NFT

### Token

**getAllowance**: It is basically the same as getApproved in NFT. However, since tokens are not just one, the total amount authorized to spend is returned.

**getTotalSupply**: Returns the total supply of the respective token
