Configuration for the Derive execution client.

Debug is implemented manually so that session_key is redacted; the derived Debug would leak the raw secret through any logger or Python __repr__.

Fields

wallet_address: Option<String>

Derive Chain smart-contract wallet address (X-LYRAWALLET). Falls back to DERIVE_WALLET_ADDRESS (or DERIVE_TESTNET_WALLET_ADDRESS on testnet) when unset.

session_key: Option<String>

secp256k1 session-key private key in hex (with or without 0x prefix). Falls back to DERIVE_SESSION_PRIVATE_KEY (or DERIVE_TESTNET_SESSION_PRIVATE_KEY on testnet) when unset.

subaccount_id: Option<u64>

Subaccount identifier. Falls back to DERIVE_SUBACCOUNT_ID (or DERIVE_TESTNET_SUBACCOUNT_ID on testnet) when unset.

base_url_rest: Option<String>

Override for the REST API base URL.

base_url_ws: Option<String>

Override for the WebSocket URL.

proxy_url: Option<String>

Optional proxy URL for HTTP and WebSocket transports.

environment: DeriveEnvironment

The Derive environment to connect to.

http_timeout_secs: u64

HTTP timeout in seconds.

max_retries: u32

Maximum number of retry attempts for HTTP requests.

retry_delay_initial_ms: u64

Initial retry delay in milliseconds.

retry_delay_max_ms: u64

Maximum retry delay in milliseconds.

ws_timeout_secs: Option<u64>

Optional per-operation WebSocket timeout in seconds (login, subscribe, reads, writes). When unset, the low-level WS_REQUEST_TIMEOUT applies.

max_fee_per_contract: Option<Decimal>

Per-contract USDC fee cap signed into every order. Required for execution and must be greater than zero.

transport_backend: TransportBackend

WebSocket transport backend (defaults to Sockudo when that feature is enabled).

domain_separator: Option<String>

Override for the EIP-712 domain separator. Falls back to the constant for the configured environment when unset. The shipped constants are placeholders that must be replaced or overridden before signing.

action_typehash: Option<String>

Override for the EIP-712 action typehash. Falls back to the shipped crate::common::consts::ACTION_TYPEHASH when unset.

trade_module_address: Option<String>

Override for the Trade module contract address. Falls back to the shipped per-environment constant when unset.

signature_expiry_secs: u64

Signature expiry TTL in seconds for normal orders and replaces (added to the wall clock before signing). Must be greater than the venue minimum (crate::common::consts::MIN_SIGNATURE_TTL, 300s).

market_order_slippage_bps: u32

Slippage bound applied to market orders when deriving a worst-acceptable limit price from the cached top-of-book quote. Expressed in basis points (1 bp = 0.01%). Defaults to 50 bp = 0.5%.

max_matching_requests_per_second: Option<u32>

Maximum matching-engine requests per second for order writes sent over the WebSocket (create/cancel/replace). Defaults to the Trader-tier limit of 1 when unset; raise it for Market Maker accounts with higher negotiated limits. See https://docs.derive.xyz/reference/rate-limits.

max_per_instrument_matching_requests_per_second: Option<u32>

Maximum per-instrument matching requests per second for instrument- scoped order writes sent over the WebSocket. Defaults to the Trader-tier limit of 1 when unset; raise it for Market Maker accounts with higher negotiated per-instrument limits. This allowance is independent of max_matching_requests_per_second, which never inflates it. See https://docs.derive.xyz/reference/rate-limits.

Implementations

impl DeriveExecClientConfig

pub fn builder() -> DeriveExecClientConfigBuilder

Create an instance of DeriveExecClientConfig using the builder syntax

impl DeriveExecClientConfig

pub fn new() -> Self

pub fn has_credentials(&self) -> bool

Returns true when wallet, session-key, and subaccount are all populated in this config. Environment-variable fallbacks documented on the individual fields are resolved at factory-construction time, not here; callers that need a “credentials available anywhere” check should inspect both this method and the relevant env vars.

pub fn validate(&self) -> Result<()>

Validates execution configuration invariants.

Errors

Returns an error when max_fee_per_contract is missing or not greater than zero.

pub fn rest_url(&self) -> String

Returns the REST API base URL, respecting environment and overrides.

pub fn ws_url(&self) -> String

Returns the WebSocket URL, respecting environment and overrides.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DeriveExecClientConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DeriveExecClientConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DeriveExecClientConfig

where DeriveExecClientConfig: Default,
