Ethereum: API for converting currency such as Euro/USD to BTC

API Ethereum: EUR conversion to BTC

With the increase in the interest of cryptocurrencies, it is constantly growing, as well as the demand for reliable API interfaces that facilitate transactions between different currencies. In this article, we will examine the API Ethereum and its possibilities to transform EUR into EUR.

What is API Ethereum?

Ethereum API (application programming interface) is a set of tools that allow programmers to interact with blockchain Ethereum and perform various tasks, such as data exchange, intelligent contract and many others. Ethereum API offers access to the Ethereum virtual machine (EVM), which allows programmers to launch the solidity code in blockchain.

Conversion from EUR to BTC through Ethereum API

In this section we will focus on transforming the coin from the euro (EUR) into Bitcoin (BTC) using the Ethereum API.

assumption

To use the Ethereum API for foreign conversion, you will need:

• Important Ethereum wallet that accepts the ERC-20 standard.

• Cryptocurrency exchange account, which accepts EUR and BTC conversions.

• API of the API Ethereum URL (which we will offer later).

API Ethereum end point for foreign conversions

The API Ethereum offers a set of monet conversion end points. In this example we will use “ETH Conwer Conwer Conwer EUR on BTC.

Here is an updated fragment of the code that shows what to call the end point “Eth Conver”:

`Javascript

Const web3 = requires ("web3");

// Set -Ethereum I URL Endpoint API URL.

Const supplement = '

Const web3provider = new web3.providers.htttpprovider (servedurl);

// Get the ETH current balance (it will be used for conversion)

Async Getethetability function () {

In Court = New Web3.Providers.httprovider (Servedurl);

Constabi = requirement ('./ Contract-abo.json');

Constantaddress = '0x ...'; // Replace the Ethereum contract address

Const txhash = wait for instance.eth.sendranstion ({{

From: contract,

Data: contracts,

Gas: "20,000",

GasePrice: "20",

});

Return Instance.eth.getbalance (ContraCTTADDress);

}

// Call the ETO end point to convert EUR to BTC

Async converteur_to_btc () {function

Const Consis Balance = Waiting for Getetthbalance ();

If (balance> 0) {

// Convert EUR to BTC using the final converting point

Const ethprice = I'm waiting for the court .th.GetBalance ("0x ..."); // Replace the Ethereum contract address

Const BTCPrice = ETHPRICE * 2.5; // convert EUR to BTC (assuming a fixed rate 1: 1)

ReturnEUR -> btc: $ {btcprice};

} otherwise {

console.log ("no ETH balance");

return '';

}

}

// Example of use:

Converteur_to_btc (). Then ((result) => {

console.log (result);

}). Catch ((error) => {

console.error (error);

});

Note : This is a simplified example that shows how to call the final point “ETH Conwer. In the application in the real world you must:

• Replace “own_project_idto the Ethereum project identifier.

2

• Make sure you use HTTPS for the URL of the Supplier (for example,https: // mainnet.infura.io/v3/your_project_id`).

future restrictions and work

Although this example ensures a basic demonstration of currency conversion via API Ethereum, there are several restrictions and areas of improvement:

• Restriction of the rate : ETO convert lens has speed limit to prevent abuse.

• Fluctuations of the currency exchange rate : Courses used in this example may not reflect current market prices.
