  * {Comparators}: A library that contains comparator functions to use with the {Heap} library.
  * {CAIP2}, {CAIP10}: Libraries for formatting and parsing CAIP-2 and CAIP-10 identifiers.
  * {Blockhash}: A library for accessing historical block hashes beyond the standard 256 block limit utilizing EIP-2935's historical blockhash functionality.
+ * {Time}: A library that provides helpers for manipulating time-related objects, including a `Delay` type.
  * {AbstractSigner}: Abstract contract for internal signature validation in smart contracts.
  * {ERC7739}: An abstract contract to validate signatures following the rehashing scheme from `ERC7739Utils`.
  * {ERC7739Utils}: Utilities library that implements a defensive rehashing mechanism to prevent replayability of smart contract signatures based on ERC-7739.
- * {Time}: A library that provides helpers for manipulating time-related objects, including a `Delay` type.
+ * {SignerECDSA}, {SignerP256}, {SignerRSA}: Implementations of an {AbstractSigner} with specific signature validation algorithms.
+ * {SignerERC7702}: Implementation of {AbstractSigner} that validates signatures using the contract's own address as the signer, useful for delegated accounts following EIP-7702.
