Welcome on ProCrypt !

ProCrypt is a small, simple, and ultrafast library for managing crypto wallets, built on Web Standards for Deno.

✨ Features

• Multi-chain wallet support (UTXO and EVM-based)
• Supports Bitcoin, Litecoin, Ethereum, BSC, Solana, and Tron
• Built-in testnet support for all chains
• Easy transaction signing and broadcasting
• Generates address from existing or new private keys

📦 Installation

deno add jsr:@webtools/procrypt

🧠 Usage Example

ProCrypt provides a unified API to interact with all supported blockchains. Here is a minimal example using Ethereum testnet. All other chain classes follow the same interface.

import * as procrypt from "jsr:@webtools/procrypt";

// Use an existing private key or leave empty to auto-generate one
const wallet = new procrypt.Chains.EthereumSepolia("0xb14e0a4c18767...");

console.log(wallet.getPrivateKey()); // => prints your private key
console.log(wallet.getAddress()); // => prints your wallet address

console.log(wallet.isValidAddress("0xb14e0a4c18767...")); // => boolean

// Sign transactions
const signedTransactions = await wallet.signTransactions([
	{ to: "0xRecipientAddress", amount: 0.001 },
]);

console.log(signedTransactions); // => array of signed raw transactions

// Broadcast transactions
const txIds = await wallet.sendTransactions(signedTransactions);
console.log(txIds); // => array of transaction IDs

🏗️ Available Classes

📚 API Overview

interface Transaction

interface Transaction {
	readonly to: string;
	readonly amount: number;
}

interface Chain

All blockchain classes implement the Chain interface:

interface Chain {
	getPrivateKey(): string;
	getAddress(): string;
	signTransactions(transactions: Transaction[]): Promise<string[]>;
	sendTransactions(transactions: string[]): Promise<string[]>;
	isValidAddress(address: string): boolean;
}
