+The BDK core library maintains a MSRV of 1.63.0. This includes `bdk_core`, `bdk_chain`, and `bdk_wallet`.
 
-The MSRV of `bdk_electrum` and `bdk_esplora` is 1.75.0

-Our policy regarding MSRV is:
-
-1. We guarantee that a crate or library builds on a particular version of Rust
-2. We do not guarantee that the MSRV will stay consistent between minor versions
-3. We make no guarantees with respect to the MSRV of example crates, crates designed for testing and development, or deprecated or experimental projects.
+The MSRV of `bdk_electrum` is 1.75.0.
+
+To build with the MSRV you will need to pin dependencies as follows:

+cargo update -p time --precise "0.3.20"
