+Config possède également l'adapter du document `std.transport` vers le contrat runtime de `ksp-onchain-transport-lib` :
+
+```rust
+let transport = match engine.load_resolved_transport_config(std::option::Option::None, &environment) {

+    std::result::Result::Err(error) => return std::result::Result::Err(error),

+
+Les scalaires `*_ms` restent des valeurs Config et sont convertis en `std::time::Duration` par l'adapter. Les URLs peuvent provenir de `KSP_PUBLIC_*` ou de `KSP_SECRET_*`; dans ce dernier cas la valeur réelle reste disponible au runtime Transport, mais `ResolvedTransportConfig::effective().safe_value()` et les représentations `Debug` sont redacted.
