Modules

curl_transport

Transport that outputs equivalent curl commands instead of making RPC requests.

fee

EIP-1559 fee estimation with configurable presets.

mpp

MPP (Machine Payments Protocol) support for 402-gated RPC endpoints.

runtime_transport

Runtime transport that connects on first request, which can take either of an HTTP, WebSocket, or IPC transport. Retries are handled by a client layer (e.g., RetryBackoffLayer) when used.

Structs

ProviderBuilder

Helper type to construct a RetryProvider

RoundRobinService

A round-robin transport that distributes requests across multiple transports.

Constants

DEFAULT_UNKNOWN_CHAIN_BLOCK_TIME 🔒

The assumed block time for unknown chains. We assume that these are chains have a faster block time.

POLL_INTERVAL_BLOCK_TIME_SCALE_FACTOR 🔒

The factor to scale the block time by to get the poll interval.

Functions

get_http_provider

Constructs a provider using try_get_http_provider.

is_rpc_method_not_found

Returns whether an RPC transport error reports JSON-RPC method-not-found.

redact_url

Returns an RPC URL safe for display by retaining only its scheme, host, and port.

resolve_path 🔒 Non-Windows

rpc_error_code 🔒

rpc_error_code_from_body 🔒

try_get_http_provider

Constructs a provider, retaining Alloy’s default polling interval for local URLs.

Type Aliases

RetryProvider

Helper type alias for a retry provider

RetryProviderWithSigner

Helper type alias for a retry provider with a signer
