Other Components

Fee Policy

Controls initial fee suggestion and replacement fee bumping.

Config Key	Meaning
fees.base_multiplier	Multiplier applied to base fee suggestion
fees.priority_tip	Initial maxPriorityFeePerGas value
tx.max_replacements	Limit of fee bump attempts

Implement custom policy by binding a new class to FeePolicy.

$this->app->singleton(FeePolicy::class, fn() => new MyAdaptivePolicy());

Nonce Management

Local nonce memory prevents collision during sequential sends. Ensure only one worker per signing address. For horizontal scaling add a distributed (Redis/DB) manager.

Signer

Encapsulates private key usage; current driver: private_key. Future extensions could allow hardware wallets or vault integration.

Health Snapshot

Quick connectivity check:

$status = \Farbcode\LaravelEvm\Facades\EvmRpc::health();

Gives chain id & latest block number.

Encoding Helpers

Use Encoding::stringToBytes32('text') for static bytes32 arguments.

Security Considerations

Concern	Recommendation
Private key exposure	Keep in env, never log
Nonce race	Single worker per address
RPC reliability	Configure multiple endpoints
Fee underpricing	Monitor TxReplaced frequency
