Laravel Evm Laravel Package

farbcode/laravel-evm

Simple, reliable Ethereum integration for Laravel with EIP-1559 fees, queued async transactions, nonce tracking, and events for every step from queued to mined. Requires PHP 8.4+ and ext-gmp.

v0.4.0

This release is the result of a full audit of the package. It fixes a group of defects that produced wrong values silently rather than failing — wrong amounts in calldata, wrong balances read back, transactions reported as successful that had reverted — plus the security issue of provider API keys being written to the log.

Several fixes necessarily change behaviour, because keeping the old behaviour means keeping the bug. Read UPGRADING.md before updating.

⚠️ Two changes that can alter what your application computes

Integers are now decimal strings. CallResult::as() and LogFilterBuilder::decodeEvent() used to return a PHP int for small values and the bare hex digits above roughly 1.15 tokens — while event decoding lost precision past 2^53 entirely. Any arithmetic on those results needs bcmath or GMP now.

// before: int(1000000000000000000)  or  string(16) "1bc16d674ec80000"
// after:  string "1000000000000000000"
$balance = $contract->call('balanceOf', [$user])->as('uint256');

at() returns a new handle. It no longer mutates the client it was called on, and the container binding is no longer a singleton. Two contract handles are now independent — previously the second at() silently retargeted the first.

Fixed

Amounts above PHP_INT_MAX were clamped in calldata. transfer($to, '10000000000000000000') encoded 9.223372036854775807 tokens instead of 10. The same cast turned a hex amount, or a forgotten argument, into 0 — which for a minOut or deadline silently removes the guard. (#14)

TxMined fired for reverted transactions. A receipt only proves inclusion; status was never read. Listeners crediting balances did so for transactions that had rolled back. Reverts now emit the new TxReverted. (#25)

Provider API keys were written to the log. All four Log calls in the RPC client, and health(), emitted the full endpoint url — which carries the key in the path. A single provider outage copied every key into laravel.log. (#20)

ltrim($x, '0x') was used as prefix removal in three places. It takes a character list, so roughly 1 in 16 inputs lost leading digits: private keys were rejected, and evm:address:generate printed silently truncated, invalid addresses. (#26)

Log topic filters were silently dropped. Filtering on topic2 alone produced a query with no topic constraint at all, returning every log in the range while looking filtered. Non-indexed string and bytes event parameters decoded to their ABI offset instead of their value. (#21)

A successfully broadcast transaction could be reported as failed. already known and nonce too low mean the node accepted the transaction; they were treated as endpoint failures and ended in TxFailed, with the nonce left unconsumed locally. (#23)

The nonce cache could wedge a worker permanently. A lost response or a dropped transaction left the cache out of step with the chain, with no way to resync short of restarting the process. (#19)

The queue job was not configured for an irreversible action. No $timeout (so the documented workers killed it mid-poll and the replacement path was unreachable), no retry guard, unprotected receipt polling that could orphan a broadcast transaction, and only the newest hash polled after a fee bump — so an original transaction winning the race was reported as failed. (#27)

Fees ignored baseFee and the priority fee, deriving both caps from eth_gasPrice and then letting Polygon-shaped floors dominate, which overpaid several times over on Ethereum. The maxFee >= priority invariant was unenforced. (#28)

The ABI encoder reshaped invalid input instead of rejecting it — uint256[] encoded as the number 1, a short address padded into a different valid address, an over-long one shifting every following word. (#22)

Added

  • Native value transfers — sendAsync($fn, $args, ['value' => '1000000000000000000']) (#29)
  • Optional transaction tracking — an evm_transactions table keyed on the id sendAsync() returns, off by default (#31)
  • One transaction at a time per signing address, enforced by a cache lock rather than by operator discipline (#30)
  • Laravel 13 support, with 11, 12 and 13 all covered in CI (#35)
  • Support\Receipt — isSuccessful() / isReverted() for callers of wait()
  • Configurable RPC transport — evm.rpc.timeout, connect_timeout, tries; plus evm.logs.max_chunk, which chunked() already read but was never shipped

Changed

  • Signer signs. The contract gained sign(), and PrivateKeySigner no longer exposes the key at all — it used to be passed as a function argument, which put it in stack traces. A KMS or HSM signer is now a plain implementation. (#24)
  • RPC errors are typed. RpcErrorException (with rpcCode, rpcData, isRevert()) for a node verdict, RpcTransportException for an unreachable endpoint. Both extend RpcException. (#23)
  • NonceManager::invalidate() and FeePolicy::suggest(FeeSnapshot) — custom implementations need updating. (#19, #28)
  • Fee defaults moved from 50/120 gwei with multiplier 3 to 1/0 with multiplier 2, since the chain now supplies the number. Polygon users should set EVM_MIN_PRIORITY_GWEI=30. (#28)
  • Missing GMP no longer takes down the whole application. The check moved out of the service provider's register() phase to where the maths happens, and ext-gmp is declared in composer.json. (#34, #37)
  • The gas floor is configurable (evm.tx.gas_floor, default 21 000). The hard-coded 150 000 reserved seven times the funds a plain transfer needs. (#34)

Removed

  • GasException — documented but never thrown; a failed estimate raises RpcErrorException
  • TxBuilder / TxBuilderEip1559 — bound in the container, never resolved
  • PrivateKeySigner::privateKey() — see above

Under the hood

The test suite went from 14 tests to 165, with no skips — the one skipped test claimed an "ECC signing overflow" that does not exist and asserted nothing. CI now runs PHP 8.4 against Laravel 11, 12 and 13 in both prefer-lowest and prefer-stable; documentation was corrected against the actual API, including a README quick start that called an undefined class.
