+The BDK library maintains a MSRV of 1.63.0. This includes the following crates:
+
+- `bdk_core`
+- `bdk_chain`
+- `bdk_bitcoind_rpc`.
+- `bdk_esplora`.
+- `bdk_wallet`.
+
+The MSRV of `bdk_electrum` is 1.75.0.
+
+To build with the MSRV of 1.63.0 you will need to pin dependencies by running the [`pin-msrv.sh`](./ci/pin-msrv.sh) script.
