Tamper-evident
SHA-256 hash chain — any tampering is instantly detectable. Eloquent logs are write-protected.
SHA-256 cryptographic hash chain on your Eloquent models. Know who changed what, when — and prove it.
use GrayMatter\AuditChain\Concerns\HasAuditTrail;
use GrayMatter\AuditChain\Contracts\Auditable;
class Order extends Model implements Auditable
{
use HasAuditTrail;

$order = Order::create(['status' => 'pending']);
$order->update(['status' => 'shipped']);Install in seconds
Add a tamper-evident cryptographic chain to your existing Eloquent models.

Add the trait
use HasAuditTrail;
Built for security
If someone modifies, deletes or inserts an entry, the chain breaks and the audit:verify command catches it immediately.
SHA-256 hash chain — any tampering is instantly detectable. Eloquent logs are write-protected.
Every change, every user, every timestamp — searchable and exportable.
Artisan command + programmatic API. Automated alerts via email and webhooks.
Use cases
Someone deleted a record. Who? When? Can you prove it?
Every change is chained. Run audit:verify.
The regulator requests a full audit log.
Export the complete chain — verifiable and tamper-evident.
A developer bypassed Eloquent to modify data directly.
The chain breaks. audit:verify catches it instantly.
