What is Ethersweep?


Ethersweep provides an online service for cryptocurrency enthusiasts (specifically Ethereum wallet holders) who are looking to convert their ERC-20 tokens into Ethereum.

You see, many Ethereum holders are unaware that their Ethereum wallets contain what are referred to as ERC-20 tokens.

Sometimes ERC20 tokens, depending upon the type of ERC-20 tokens and volume, can amount to hundreds up to thousands of dollars in value.

Usually extracting and exchanging ERC-20 tokens is a tedious, technical process that results in disproportionate service fees for low value conversions.

In other words, traditionally speaking the conversion of ERC-20 tokens is not worth the hassle due to the complexity and time consumption usually exhibited by the conversion process.

However, according to Ethersweep, they have overcome this problem with their modern and easy to use solution.

What Are ERC-20 Tokens?

It is important to understand that Ethereum is a cryptocurrency and blockchain system that is based on the use of tokens which can be bought, traded, or sold.

These tokens can be used to represent a vast variety of digital assets such as IOUs, vouchers, or tangible goods.

In other words, these tokens can be considered as smart contracts that are then utilized in the Ethereum blockchain.

According to Investopedia, ERC-20 tokens are among the most significant token variants and the ERC-20 format is considered by many as the Gold Standard for asset tokenisation on the Ethereum blockchain. For that reason most Ethereum based IPO coin issuance has used the ERC-20 standard.

As of April 16th, 2019, there is said to be more than 181,000 ERC-20 compatible token types in existence on the main Ethereum network.

One of the characteristics making ERC-20 tokens such a powerhouse in the blockchain space comes from developers’ ability to accurately predict how new ERC-20 tokens will function within the Ethereum ecosystem prior to use.

Not only does this advantage drastically cut down project development time but also greatly improves efficiency later down the road.

As for the future of ERC-20 tokens, most experts agree ERC20 tokens will remain a leading smart token format and powerful mechanic for blockchain based transactable asset representation as the ecosystem continues to mature.
