Produces a `0x02`-prefixed raw transaction hex ready for `eth_sendRawTransaction`. Signatures are **deterministic per RFC 6979** and canonical low-S, so the same `(privateKey, transaction)` pair always yields byte-identical output — ideal for reproducible builds, server-side signing, and EVM bridge/withdrawal automation. Features -------- [](#features) - EIP-1559 / EIP-2718 Type-2 transaction assembly (RLP-encoded, `0x02`-prefixed). - RFC 6979 deterministic ECDSA signing over secp256k1, canonical low-S. - Sender address derivation from the private key. - Bigint-safe wei / gas fields via decimal strings (`ext-gmp`). - Empty-key placeholder mode keeps DI containers booting without the real secret. - PHPStan level 9 clean, `strict_types`. Why amashukov/eip1559-tx-signer-php ----------------------------------- [](#why-amashukoveip1559-tx-signer-php) The common PHP path to a signed EVM transaction is `web3p/ethereum-tx` + `kornrunner/ethereum-offline-raw-tx`, which target the legacy transaction shape and pull in their own crypto stack. This package is focused on the modern Type-2 (EIP-1559) envelope with RFC 6979 deterministic signing as a first-class guarantee, composed from small single-purpose dependencies you can audit independently (keccak / RLP / secp256k1). Installation ------------ [](#installation) ``` composer require amashukov/eip1559-tx-signer-php ``` Usage ----- [](#usage) ``` use Amashukov\Eip1559TxSigner\Eip1559Signer; $signer = new Eip1559Signer('0x4f3edf983ac636a65a842ce7c78d9aa706d3b113bce9c46f30d7d21715b23b1d', chainId: 1); // Sender address derived from the private key: echo $signer->address(); // 0x90f8bf6a479f320ead074411a4b0e7944ea8c9c1 $rawTx = $signer->sign( to: '0x000000000000000000000000000000000000dEaD', valueWei: '0', // decimal-string wei (bigint-safe) data: '0xf3fef3a3…', // calldata, 0x-prefixed nonce: 5, gasLimit: 100_000, maxFeePerGas: '30000000000', // 30 gwei maxPriorityFeePerGas: '1500000000', // 1.5 gwei ); // 0x02f8b1… — broadcast via eth_sendRawTransaction ``` ### Empty-key placeholder [](#empty-key-placeholder) Passing an empty private key boots the signer with an all-ones placeholder key. This keeps dependency-injection containers booting in dev/test without the real secret; the resulting transaction is signed by a throwaway key, so any chain that receives it rejects the call — loudly, not silently. ### Interface for DI / test doubles [](#interface-for-di--test-doubles) `Eip1559Signer` implements `Eip1559SignerInterface` (`address()` + `sign()`). Type-hint the interface in your services and the container wires the concrete signer in production; in tests, swap a deterministic, key-free double for the interface so signing output never depends on a real private key. ``` use Amashukov\Eip1559TxSigner\Eip1559SignerInterface; public function __construct(private Eip1559SignerInterface $signer) {} ``` How it works ------------ [](#how-it-works) 1. RLP-encode `[chainId, nonce, maxPriorityFeePerGas, maxFeePerGas, gasLimit, to, value, data, accessList]` and prepend the `0x02` type byte. 2. keccak-256 the payload → signing hash. 3. ECDSA-sign the hash with secp256k1 (RFC 6979 deterministic nonce, canonical low-S). 4. RLP-encode the same fields plus `[yParity, r, s]`, prepend `0x02` → the signed raw transaction. Access lists are emitted empty; the signer targets the common "no access list" Type-2 transaction.
