+# Hash Solidity Compatible
+
+This contract demonstrates Keccak hashing in Cairo to match Solidity's keccak256. While both use Keccak, their endianness differs: Cairo is little-endian, Solidity big-endian. The contract achieves compatibility by hashing in big-endian using `keccak_u256s_be_inputs`, and reversing the bytes of the result with `u128_byte_reverse`.
+
+For example:
+
+```rust
+{{#include ../../listings/ch02-advanced-concepts/hash_solidity_compatible/src/contract.cairo}}
+```
+
+Play with the contract in [Remix](https://remix.ethereum.org/?#activate=Starknet&url=https://github.com/NethermindEth/StarknetByExample/blob/main/listings/ch02-advanced-concepts/hash_solidity_compatible/src/contract.cairo).
