+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+contributor@scroll.io.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

+<a href="https://scroll.io">Scroll</a> is a zkRollup Layer 2 dedicated to enhance Ethereum scalability through a bytecode-equivalent [zkEVM](https://github.com/scroll-tech/zkevm-circuits) circuit. This monorepo encompasses essential infrastructure components of the Scroll protocol. It contains the L1 and L2 contracts, the rollup node, the prover client, and the prover coordinator.

+
+## Contributing
+
+We welcome community contributions to this repository. Before you submit any issues or PRs, please read the [Code of Conduct](CODE_OF_CONDUCT.md) and the [Contribution Guideline](CONTRIBUTING.md).
+
+## Prerequisites
++ Go 1.19
++ Rust (for version, see [rust-toolchain](./common/libzkp/impl/rust-toolchain))
++ Hardhat / Foundry
++ Docker
+
+To run the tests, it is essential to first pull or build the required Docker images. Execute the following commands in the root directory of the repository to do this:
+
+```bash
+docker pull postgres
+make dev_docker
+```
+
+## Testing Rollup & Coordinator
+
+### For Non-Apple Silicon (M1/M2) Macs
+
+Run the tests using the following commands:
+
+```bash
+go test -v -race -covermode=atomic scroll-tech/rollup/...
+go test -tags="mock_verifier" -v -race -covermode=atomic scroll-tech/coordinator/...
+go test -v -race -covermode=atomic scroll-tech/database/...
+go test -v -race -covermode=atomic scroll-tech/common/...
+```
+
+### For Apple Silicon (M1/M2) Macs
+
+To run tests on Apple Silicon Macs, build and execute the Docker image as outlined below:
+
+#### Build a Docker Image for Testing
+
+Use the following command to build a Docker image:
+
+```bash
+make build_test_docker
+```
+
+This command builds a Docker image named `scroll_test_image` using the Dockerfile found at `./build/dockerfiles/local_test.Dockerfile`.
+
+#### Run Docker Image
+
+After the image is built, run a Docker container from it:
+
+```bash
+make run_test_docker
+```
+
+This command runs a Docker container named `scroll_test_container` from the `scroll_test_image` image. The container uses the host network and has access to the Docker socket and the current directory.
+
+Once the Docker container is running, execute the tests using the following commands:
+
+```bash
+go test -v -race -covermode=atomic scroll-tech/rollup/...
+go test -tags="mock_verifier" -v -race -covermode=atomic scroll-tech/coordinator/...
+go test -v -race -covermode=atomic scroll-tech/database/...
+go test -v -race -covermode=atomic scroll-tech/common/...
+```
+
+## Testing Contracts
+
+You can find the unit tests in [`contracts/src/test/`](/contracts/src/test/), and integration tests in [`contracts/integration-test/`](/contracts/integration-test/).
+
+See [`contracts`](/contracts) for more details on the contracts.

+# bridge-history-api
+
+This directory contains the `bridge-history-api` service that provides REST APIs to query txs interact with Scroll official bridge contracts
+
+## Instructions
+The bridge-history-api contains three distinct components
+
+### bridgehistoryapi-db-cli
+
+Provide init, show version, rollback, check status services of DB
+```
+    cd ./bridge-history-api
+    make bridgehistoryapi-db-cli
+    ./build/bin/bridgehistoryapi-db-cli [command]
+```
+
+### bridgehistoryapi-cross-msg-fetcher
+
+Fetch the transactions from both l1 and l2
+```
+    cd ./bridge-history-api
+    make bridgehistoryapi-cross-msg-fetcher
+    ./build/bin/bridgehistoryapi-cross-msg-fetcher
+```
+
+### bridgehistoryapi-server
+
+provides REST APIs. Please refer to the API details below.
+```
+    cd ./bridge-history-api
+    make bridgehistoryapi-server

-# Bridge
-
-This repo contains the Scroll bridge.
-
-In addition, launching the bridge will launch a separate instance of l2geth, and sets up a communication channel
-between the two, over JSON-RPC sockets.
-
-Something we should pay attention is that all private keys inside sender instance cannot be duplicated.
