+          notices within Derivative Works that You distribute, alongside

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# revive
+
+YUL and EVM bytecode recompiler to LLVM, targetting RISC-V on PolkaVM.
+
+Code bases of [frontend](https://github.com/matter-labs/era-compiler-solidity) and [code generator](https://github.com/matter-labs/era-compiler-llvm-context) are forked and adapted from ZKSync `zksolc`.
+
+# Status
+
+Currently, primary goal of this codebase is to allow for benchmarks comparing performance against ink! and solang artifacts as well as EVM interpreters.
+
+# TODO
+
+The project is in a very early PoC phase. Don't yet expect the produced code to be working nor to be correct for anything more than a basic flipper contract at the current stage.
+
+- [ ] Efficient implementations of byte swaps, memset, memmove, mulmod and the like
+- [ ] Use `drink` for integration tests once we have 64bit support in PolkaVM
+- [x] Use PolkaVM allocator for heap space
+- [ ] Exercice `schlau` and possibly `smart-bench` benchmark cases
+- [x] Tests currently rely on the binary being in $PATH, which is very annoying and requires `cargo install` all the times
+- [ ] Define how to do deployments
+- [ ] Calling conventions for calling other contracts
+- [ ] Runtime environment isn't fully figured out; implement all EVM builtins
+- [ ] Iron out many leftovers from the ZKVM target
+    - [ ] Use of exceptions
+    - [ ] Change long calls (contract calls)
+    - [ ] Check all alignments, attributes etc. if they still make sense with our target
+    - [x] Custom extensions related to zk VM
+    - [ ] `Active Pointer`: Redundant to calldata forwarding in pallet contracts. [Mainly used here](https://github.com/matter-labs/era-contracts/blob/4aa7006153ad571643342dff22c16eaf4a70fdc1/system-contracts/contracts/libraries/EfficientCall.sol) however we could offer a similar optimization.
+    - []
+- [ ] Add a lot more test cases
+- [ ] Debug information
+- [ ] Look for and implement further optimizations
+- [ ] Differential testing against EVM
+- [x] Switch to LLVM 18 which has `RV{32,64}E` targets upstream
+- [ ] Minimize scope of "stdlib"
+- [ ] Document differences from EVM
+- [ ] Audit for bugs and correctness
+- [x] Rebranding
