+# Branch Strategy for MEV Bot Project
+
+This document outlines the branching strategy for the MEV Bot project.
+
+## Branch Types
+
+### 1. Main Branches
+
+#### `main`
+- Contains production-ready code
+- Only accepts merges from `release/*` branches
+- Always stable and deployable
+- Protected branch - requires pull requests and code review
+
+#### `develop`
+- Main development branch
+- Contains latest delivered development changes
+- All feature branches merge here
+- Automated CI/CD pipeline runs on this branch
+
+### 2. Supporting Branches
+
+#### `feature/*`
+- Used for developing new features
+- Branch from: `develop`
+- Merge back to: `develop`
+- Branch naming: `feature/<descriptive-name>`
+- Examples:
+  - `feature/add-market-scanner`
+  - `feature/improve-uniswap-pricing`
+  - `feature/add-logging`
+
+#### `fix/*`
+- Used for bug fixes in development
+- Branch from: `develop`
+- Merge back to: `develop`
+- Branch naming: `fix/<descriptive-name>`
+- Examples:
+  - `fix/resolve-memory-leak`
+  - `fix/correct-pricing-calculation`
+
+#### `release/*`
+- Used for release preparation
+- Branch from: `develop`
+- Merge back to: `main` and `develop`
+- Branch naming: `release/<version>`
+- Examples:
+  - `release/v1.2.0`
+  - `release/v2.0.0`
+
+#### `hotfix/*`
+- Used for critical production fixes
+- Branch from: `main`
+- Merge back to: `main` and `develop`
+- Branch naming: `hotfix/<descriptive-name>`
+- Examples:
+  - `hotfix/security-patch`
+  - `hotfix/critical-bug-fix`
+
+## Workflow Examples
+
+### Feature Development Workflow
+```bash
+# 1. Create feature branch from develop
+git checkout develop
+git pull origin develop
+git checkout -b feature/add-market-scanner
+
+# 2. Develop feature
+# ... make changes ...
+git add .
+git commit -m "feat(market): implement basic market scanner"
+
+# 3. Keep feature branch up to date
+git checkout develop
+git pull origin develop
+git checkout feature/add-market-scanner
+git rebase develop
+
+# 4. Push feature branch
+git push -u origin feature/add-market-scanner
+
+# 5. Create Pull Request on GitHub/GitLab
+# 6. After PR approval and merge, delete branch
+git checkout develop
+git pull origin develop
+git branch -d feature/add-market-scanner
+git push origin --delete feature/add-market-scanner
+```
+
+### Release Workflow
+```bash
+# 1. Create release branch from develop
+git checkout develop
+git pull origin develop
+git checkout -b release/v1.2.0
+
+# 2. Prepare release
+# ... bump version numbers, update docs ...
+git add .
+git commit -m "chore(release): prepare v1.2.0"
+
+# 3. Merge to main
+git checkout main
+git pull origin main
+git merge release/v1.2.0
+git tag -a v1.2.0 -m "Release v1.2.0"
+git push origin main --tags
+
+# 4. Merge to develop
+git checkout develop
+git pull origin develop
+git merge release/v1.2.0
+git push origin develop
+
+# 5. Delete release branch
+git branch -d release/v1.2.0
+git push origin --delete release/v1.2.0
+```
+
+### Hotfix Workflow
+```bash
+# 1. Create hotfix branch from main
+git checkout main
+git pull origin main
+git checkout -b hotfix/critical-security-issue
+
+# 2. Fix issue
+# ... make changes ...
+git add .
+git commit -m "fix(security): resolve critical vulnerability"
+
+# 3. Merge to main
+git checkout main
+git pull origin main
+git merge hotfix/critical-security-issue
+git tag -a v1.1.1 -m "Hotfix v1.1.1"
+git push origin main --tags
+
+# 4. Merge to develop
+git checkout develop
+git pull origin develop
+git merge hotfix/critical-security-issue
+git push origin develop
+
+# 5. Delete hotfix branch
+git branch -d hotfix/critical-security-issue
+git push origin --delete hotfix/critical-security-issue
+```
+
+## Branch Protection Rules
+
+### `main` Branch
+- Require pull request reviews before merging
+- Require status checks to pass before merging
+- Require branches to be up to date before merging
+- Include administrators in restrictions
+- Allow force pushes: No
+- Allow deletions: No
+
+### `develop` Branch
+- Require pull request reviews before merging
+- Require status checks to pass before merging
+- Include administrators in restrictions
+- Allow force pushes: No
+- Allow deletions: No
+
+## Naming Conventions
+
+### Good Examples
+- `feature/add-uniswap-v3-support`
+- `fix/resolve-arbitrum-parser-bug`
+- `release/v2.1.0`
+- `hotfix/security-patch`
+
+### Avoid These
+- `feature/fix` (unclear)
+- `bugfix` (use `fix/` instead)
+- `new-stuff` (not descriptive)
+- `feature1` (not descriptive)
+
+## Best Practices
+
+1. **Keep branches short-lived** - Max 1-2 weeks
+2. **Use descriptive names** - Clearly indicate purpose
+3. **Keep features small** - One branch per logical feature
+4. **Regularly sync with develop** - Prevent large merge conflicts
+5. **Delete branches after merging** - Keep repository clean
+6. **Use pull requests** - Enable code review and discussion
+7. **Write meaningful commit messages** - Help with code review
+8. **Tag releases** - Enable easy rollback and version tracking
+
+This branching strategy ensures a clean, organized Git history while enabling parallel development and maintaining code quality.
