-YUL and EVM assembly recompiler to LLVM, targetting RISC-V on [PolkaVM](https://github.com/koute/polkavm).
+YUL and EVM bytecode recompiler to LLVM, targetting RISC-V on PolkaVM.

-[Frontend](https://github.com/matter-labs/era-compiler-solidity) and [code generator](https://github.com/matter-labs/era-compiler-llvm-context) are based of ZKSync `zksolc`.
+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
+# Status

-This is experimental software in active development and not ready just yet for production usage.
+Currently, primary goal of this codebase is to allow for benchmarks comparing performance against ink! and solang artifacts as well as EVM interpreters.

-Discussion around the development is hosted on the [Polkadot Forum](https://forum.polkadot.network/t/contracts-update-solidity-on-polkavm/6949#a-new-solidity-compiler-1).
+# TODO

-## Installation
+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.

-`resolc` depends on the [solc](https://github.com/ethereum/solidity) binary installed on your system.
-
-To install the `resolc` Solidity frontend executable:
-
-```bash
-bash build-llvm.sh
-export PATH=${PWD}/llvm18.0/bin:$PATH
-make install-bin
-resolc --version
-```
-
-### LLVM
-
-`revive` requires a build of LLVM 18.1.4 or later including `compiler-rt`. Use the provided [build-llvm.sh](build-llvm.sh) build script to compile a compatible LLVM build locally in `$PWD/llvm18.0` (don't forget to add that to `$PATH` afterwards). 
-
-### Development
-
-Please consult the [Makefile](Makefile) targets to learn how to run tests and benchmarks. 
-Ensure that your branch passes `make test` locally when submitting a pull request.
-
-## Design overview
-`revive` uses [solc](https://github.com/ethereum/solidity/), the Ethereum Solidity compiler, as the [Solidity frontend](crates/solidity/src/lib.rs) to process smart contracts written in Solidity. The YUL IR code (or legacy EVM assembly as a fallback for older `solc` versions) emitted by `solc` is then translated to LLVM IR, targetting [Polkadots `revive` pallet](https://docs.rs/pallet-revive/latest/pallet_revive/trait.SyscallDoc.html).
+- [ ] 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
+- [ ] Rebranding

-# Release checklist
-
-Prior to the first stable release we neither have formal release processes nor do we follow a fixed release schedule.
-
-To create a new pre-release:
-
-1. Merge a release PR which updates the `-dev.X` versions in the workspace `Cargo.toml` and updates the `CHANGELOG.md` accordingly
-2. Push a release tag to `main`
-3. Manually trigger the `Build revive-debian` action
-4. Create a __pre-release__ from the tag and manually upload the build artifact generated by the action
-5. Update the [contract-docs](https://github.com/paritytech/contract-docs/) accordingly

+
+[![Logo](eraLogo.svg)](https://zksync.io/)
+
+zkSync Era is a layer 2 rollup that uses zero-knowledge proofs to scale Ethereum without compromising on security
+or decentralization. As it's EVM-compatible (with Solidity/Vyper), 99% of Ethereum projects can redeploy without
+needing to refactor or re-audit any code. zkSync Era also uses an LLVM-based compiler that will eventually enable
+developers to write smart contracts in popular languages such as C++ and Rust.
+
+This repository contains the common compiler constants.
