A Symfony Form validation library for cryptocurrency addresses and transaction hashes. This library provides custom validation constraints to validate cryptocurrency addresses and verify transaction hashes against their respective blockchain networks.

📋 Purpose
---------

[](#-purpose)

This library enables Symfony applications to:

- **Validate cryptocurrency wallet addresses** with proper format checking
- **Verify transaction hashes** against real blockchain networks
- **Integrate seamlessly** with Symfony Form components
- **Support multiple cryptocurrencies** with a unified interface

Perfect for applications that need to validate user-provided cryptocurrency data, such as:

- Payment processors
- Cryptocurrency exchanges
- Wallet applications
- DeFi platforms

[](#address-validation-features)

- **Ethereum**: EIP-55 checksum validation, proper hex format, length validation
- **Tron**: Base58 encoding validation, checksum verification, proper format

### Transaction Validation Features

[](#transaction-validation-features)

- **Ethereum**: 0x-prefixed hex format, 66-character length, network existence check

🚀 Future Plans
--------------

[](#-future-plans)

### Upcoming Cryptocurrency Support

[](#upcoming-cryptocurrency-support)

We plan to add support for more cryptocurrencies:

- **Bitcoin (BTC)** - Address validation and transaction verification
- **Litecoin (LTC)** - P2PKH, P2SH, and Bech32 address formats
- **Cardano (ADA)** - Byron and Shelley address formats
- **Polkadot (DOT)** - SS58 address format validation
- **Binance Smart Chain (BSC)** - Ethereum-compatible validation
- **Polygon (MATIC)** - Ethereum-compatible validation

### Technical Improvements

[](#technical-improvements)

- **HTTP Client Integration**: Replace `file_get_contents()` with proper HTTP client (Guzzle/Symfony HTTP Client) in Ethereum validator for:

    - Better error handling
    - Timeout configuration
    - Request/response middleware
    - Retry mechanisms
    - Connection pooling
- **Async Validation**: Support for asynchronous transaction verification
- **Caching Layer**: Add caching for API responses to reduce external calls
- **Rate Limiting**: Built-in rate limiting for API calls
- **Mock Providers**: Test-friendly mock implementations
