How to Build a Crypto Wallet with Python, Web3 & CoinGecko api
I wanted to share a detailed article written based on CoinGecko API and Python to build a Crypto Wallet.
A crypto wallet is a software program that allows you to store, send, and receive digital currencies, such as Bitcoin, Ethereum, or Dogecoin. A crypto wallet also lets you interact with the underlying blockchain network, which is a distributed ledger that records all the transactions in the system.
Blockchain network
A blockchain network is a distributed ledger that records all the transactions in the system and is maintained by a network of nodes that follow a consensus protocol. A digital currency is a unit of value that is created and transferred using cryptographic techniques, such as hashing, digital signatures, and encryption.
Python
Python is a popular and versatile programming language that has many libraries and frameworks for developing crypto applications. Web3 is a collection of libraries that enable you to interact with the Ethereum network using smart contracts and decentralized applications. A smart contract is a self-executing program that runs on the blockchain and defines the rules and logic of a transaction. A decentralized application is a user interface that connects to the blockchain and allows users to interact with smart contracts. Coingecko api is a platform that provides various tools and services for crypto enthusiasts, such as market data, exchange rates, and blockchain explorers.
CoinGecko Api
I have used the CoinGecko API to fetch the market chart data for cryptocurrencies. The CoinGecko API has a free Demo plan accessible to all users with a 30 calls/min rate limit and a monthly cap of 10,000 calls. Sign up for a CoinGecko account and apply for the Demo plan to generate your complimentary API key.
Blog
In this blog post, I also have explained how to use Python, web3, and coingecko api to build a crypto wallet app that can perform the following functions:
- Connect to the Ethereum network using a provider, such as Infura.
- Generate a pair of public and private keys using the Elliptic Curve Digital Signature Algorithm (ECDSA).
- Create a transaction object that specifies the sender, receiver, amount, and gas fee of the transaction.
- Sign the transaction using your private key and the transaction data.
- The application can fetch and display the market chart data for a specific contract in USD. It uses CoinGecko API to get the market chart data..
