BURST support for ERC20 tokens
|BURST support for ERC20 tokens|
Table Of Contents
ERC20 is a popular Ethereum standard for token management, explained here https://github.com/ethereum/EIPs/issues/20
The BURST asset exchange already supports most of the ERC20 operations out of the box without the need to issue a smart contract.
This document explains how to implement the ERC20 APIs using the equivalent BURST APIs.
Each ERC20 token is represented as a BURST asset.
Issue the asset using the issueAsset API.
Each asset is identified by a unique asset id set to the transaction id of the issueAsset transaction.
Implementing the ERC20 APIs
To get the total token supply invoke the getAsset API and supply the asset id. The total supply is provided by the
initialQuantityQNT attribute, the existing supply, after possible share deletes, is specified by the
quantityQNT attribute. Quantity values are always provided as integer values, the number of decimal positions to apply to these quantities is specified by the "decimals" attribute.
To get the account balance of another account with a given address, invoke the getAssetAccounts API and provide the BURST address as the
account parameter and the asset id as the
Here is an example.
unconfirmedQuantityQNT attribute in the response represents the current account balance. The
quantityQNT attribute represents the quantity available for use at the moment after taking into account balance locked by open asset orders.
To send tokens from your address to another address use the transferAsset API, specify the recipient address, the asset id and the quantity to transfer as well as your account passphrase, the transaction fee and transaction deadline.
