Practical overview

When it fits

Use it when a PHP application needs to construct Ethereum transaction objects and sign them. The documented examples cover transaction preparation and signing, not network submission.

Who it is for

  • PHP developers adding Ethereum transaction construction and signing to an application.
  • Developers preparing EIP-1559 or EIP-2930 transaction objects in PHP.

Documented uses

  • Create a standard transaction object from fields including nonce, sender, recipient, gas, value and data.
  • Prepare EIP-1559 transactions with priority-fee and maximum-fee fields.
  • Create EIP-2930 transaction objects with access-list fields.
  • Sign a transaction object using a private key.
Before you choose

Requirements & limits

The repository is public, identifies the package as open source, and specifies the MIT license. Installation is documented through Composer.

  • The package is a PHP library, not a hosted transaction service.
  • EIP-1559 and EIP-2930 examples require a chain ID and include access-list fields.
  • The signing example supplies a private key directly to the transaction object's sign method.
  • The README does not document network submission or retrieval of transaction parameters.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Construct and sign a standard Ethereum transaction

Create a standard transaction object and sign it with a private key.

Before you start

  • The web3p/ethereum-tx package is installed.
  • Transaction parameters and a private key are available.

Steps

  1. Import Web3p\EthereumTx\Transaction.

  2. Create a Transaction with parameters such as nonce, sender (from), recipient (to), gas, gas price, value, and data; chainId is shown as optional.

  3. Call $transaction->sign('your private key') and assign the result to $signedTransaction.

Expected outcome

The example assigns the result of signing the transaction to `$signedTransaction`.

Guide limitations

  • The example does not document broadcasting the signed transaction or verifying it.
  • The private key is supplied directly to the signing method in the example; key storage practices are not described.
