Ethereum: Making a payment processor like like bitpay
Ethereum, as a leging cryptocurrency platform, offrs a stable development of environment decentralized aplication (DAPP) and pastors. In this article, we will tell the measures needed to crate a similar Payment processor BitPay Useum Blockchain.
Understanding BitPay Architecture
It is an important to understand Howks beefore diving in your unpayment processor. BitPay is an exchange of peer cryptocurrency that allows to send and receive Bitcoin (BTC) directly from ther. The platform uses the Ethereum network to the processes of payments its API.
To repeat this funity for Ethereum Blockcha, you! ereum ecosystem.
Required tools and technology
To the crate a parament of processor BitPay, you will need:
1
Ethereum Developer Tools : Check out the Ethereum development environment uses tools as a truffle set, web3 or remix.
- Solidity : Write smart contractions with define payment procesing logic and interacting With exernal services.
3
Web3.JS : Integrate Web3.You for interacting with Ethereum Blockcha and a web interface for screen.
- Payment Gateway API : Use API provided by payment gateways soach as Stripe, PayPal or Square to handle transactions on your platform.
Step by step guide
Here is a thep by step guide to the crate a payment processor to BitPay:
- Define yourse case : Identify s.
- Select ERC-20 markers : Select ERC-20 markers (eg USDT or Dai) that that will be used as a payment marker on your platform.
3
Create a smart contraction : Write Solidity Smart Agrement to define payment processing logic, including:
* Payment Gateway Integration: Use the Web3.Y API totnect to external services and transactions.
* Token Management: Treat the cration of markers, transfer and exchange between users and payment gates.
- Design the web interface : Create a web interface use HTML5, CSS3 and JavaScript so users can can from the interact.
- Checking and Repeat : Carefully check the implementation, collector reviews and repeat
Example of use: Simple paste processor creation
To illstrate this process, let’s of the create a simple payment processor example that can a handle Bitcoin (BTC) transaction using ERC-20 markers (USDT).
`SOLIDITY
Pragma Solidity ^0.6.0;
the contraction in the parameter processes {
// Mapping of users on their wallet
mapping (address => uint256) Public consumer site;
// Function to create a new dayway gateway connction
Function Createconnction () Internal return (payable address, by memory) {
// Use Stripe API tot to the past
Request (both.Encodeepacked (” “Your_strip_scret_key”)))> = 1;
Address Paygateway = both.Encodepacked (
” +
bys (both.Encodepacked (“Your_strip_secret_key”)) + “.json”,
“Your_strip_secret_key”
);
(Address narrative gateway, by memory metadati) = Web3.Theutil.
