+
+# Celo Core Contracts Release
+
+Deploy and test Celo core contract releases using Foundry-based tooling.
+
+## Quick Reference
+
+| Step | Command | Output |
+|------|---------|--------|
+| 1. Generate libraries.json | `verify-deployed:foundry -b <PREVIOUS_TAG>` | `libraries.json` |
+| 2. Generate report | `check-versions:foundry -a <PREVIOUS_TAG> -b <NEW_BRANCH>` | `releaseData/versionReports/releaseN-report.json` |
+| 3. Deploy & create proposal | `make-release:foundry -b <NEW_BRANCH>` | `proposal.json` + deployed contracts |
+
+## Networks
+
+| Network | Chain ID | RPC URL | Use Case |
+|---------|----------|---------|----------|
+| Celo Mainnet | 42220 | https://forno.celo.org | Production releases |
+| Celo Sepolia | 11142220 | https://forno.celo-sepolia.celo-testnet.org | Testnet releases |
+| Local Fork | varies | http://127.0.0.1:8545 | Testing releases |
+
+## Deployer Keys
+
+Deployer keys are stored in encrypted mnemonic files in the repo root:
+
+| Network | Mnemonic File | Encrypted File |
+|---------|--------------|----------------|
+| Celo Sepolia | `.env.mnemonic.celosepolia` | N/A (manual) |
+| Mainnet | `.env.mnemonic.mainnet` | `.env.mnemonic.mainnet.enc` |
+
+### Decrypting Keys (cLabs employees)
+
+```bash
+# Decrypt all mnemonic files using GCP KMS
+yarn keys:decrypt
+```
+
+### Using Keys
+
+Each mnemonic file exports `DEPLOYER_PRIVATE_KEY`. Source it before running release commands:
+
+```bash
+# For Celo Sepolia
+source .env.mnemonic.celosepolia
+
+# For Mainnet
+source .env.mnemonic.mainnet
+```
+
+Then use `$DEPLOYER_PRIVATE_KEY` in release commands.
+
+## Release Workflow
+
+### Step 0: Confirm Release Parameters with User
+
+**IMPORTANT**: Before executing any release commands, you MUST:
+
+1. Query available tags and branches:
+   ```bash
+   git tag -l 'core-contracts.*' | sort -V | tail -15
+   git branch -a | grep 'release/core-contracts'
+   ```
+
+2. Determine the release source using this priority order:
+
+   **Tag priority (check in order, use first match):**
+   1. Post-audit tag (if exists): `core-contracts.vN.post-audit` or `core-contracts.vN.post_audit`
+   2. Base tag: `core-contracts.vN`
+   3. Release branch: `release/core-contracts/N` (only if no tags exist)
+
+   **Note**: Not all releases have post-audit tags. If one exists, use it; otherwise use the base tag.
+
+   **For the NEW release**: Check for post-audit tag first, then base tag, then branch.
+   **For the PREVIOUS release**: Same logic - use post-audit tag if available, otherwise base tag.
+
+3. Present a confirmation to the user with:
+   - **Previous release tag** (for libraries.json): e.g., `core-contracts.v14` or `core-contracts.v14.post-audit`
+   - **New release source**: Following the priority above
+   - **Target network**: e.g., `celo-sepolia` or `celo`
+
+4. Use the AskQuestion tool to get explicit confirmation:
+   - Option to confirm the proposed tags/branches
+   - Option to specify different tag/branch
+
+5. Only proceed with the release after user confirmation.
+
+Example confirmation prompt (when post-audit tag exists):
+```
+I plan to release with the following parameters:
+- Previous release tag: core-contracts.v14.post-audit
+- New release tag: core-contracts.v15.post-audit
+- Target network: celo-sepolia
+
+Please confirm or specify different values.
+```
+
+Example confirmation prompt (when only base tag exists):
+```
+I plan to release with the following parameters:
+- Previous release tag: core-contracts.v14
+- New release tag: core-contracts.v15
+- Target network: celo-sepolia
+
+Please confirm or specify different values.
+```
+
+Example confirmation prompt (when only branch exists):
+```
+I plan to release with the following parameters:
+- Previous release tag: core-contracts.v14
+- New release branch: release/core-contracts/15 (no tag found)
+- Target network: celo-sepolia
+
+Please confirm or specify different values.
+```
+
+### Step 1: Generate libraries.json
+
+Verify the **currently deployed** release to get library addresses:
+
+```bash
+cd packages/protocol
+
+# For Celo Sepolia
+yarn release:verify-deployed:foundry -b core-contracts.v${PREVIOUS} -n celo-sepolia
+
+# For Mainnet
+yarn release:verify-deployed:foundry -b core-contracts.v${PREVIOUS} -n celo
+```
+
+**Output**: `libraries.json` in `packages/protocol/`
+
+### Step 2: Generate Compatibility Report
+
+Compare previous release to new release branch:
+
+```bash
+yarn release:check-versions:foundry \
+  -a core-contracts.v${PREVIOUS} \
+  -b release/core-contracts/${NEW} \
+  -r ./releaseData/versionReports/release${NEW}-report.json
+```
+
+**Output**: `releaseData/versionReports/release${NEW}-report.json`
+
+### Step 3: Prepare Initialization Data
+
+Create or verify initialization data exists:
+
+```bash
+# Check if file exists
+cat ./releaseData/initializationData/release${NEW}.json
+
+# If missing, create empty (valid if no new contracts)
+echo "{}" > ./releaseData/initializationData/release${NEW}.json
+```
+
+### Step 4: Deploy Release
+
+#### On Local Fork (Testing)
+
+```bash
+yarn release:make:foundry \
+  -b release/core-contracts/${NEW} \
+  -k $DEPLOYER_PRIVATE_KEY \
+  -i ./releaseData/initializationData/release${NEW}.json \
+  -l ./libraries.json \
+  -n celo-sepolia \
+  -p ./proposal-fork.json \
+  -r ./releaseData/versionReports/release${NEW}-report.json \
+  -u http://127.0.0.1:8545
+```
+
+#### On Celo Sepolia
+
+```bash
+yarn release:make:foundry \
+  -b release/core-contracts/${NEW} \
+  -k $CELO_SEPOLIA_DEPLOYER_KEY \
+  -i ./releaseData/initializationData/release${NEW}.json \
+  -l ./libraries.json \
+  -n celo-sepolia \
+  -p ./proposal-celo-sepolia.json \
+  -r ./releaseData/versionReports/release${NEW}-report.json
+```
+
+#### On Mainnet
+
+```bash
+# First regenerate libraries.json for mainnet!
+yarn release:verify-deployed:foundry -b core-contracts.v${PREVIOUS} -n celo
+
+yarn release:make:foundry \
+  -b release/core-contracts/${NEW} \
+  -k $MAINNET_DEPLOYER_KEY \
+  -i ./releaseData/initializationData/release${NEW}.json \
+  -l ./libraries.json \
+  -n celo \
+  -p ./proposal-mainnet.json \
+  -r ./releaseData/versionReports/release${NEW}-report.json
+```
+
+## Release Artifacts
+
+| Artifact | Location | Purpose |
+|----------|----------|---------|
+| `libraries.json` | `packages/protocol/` | Library addresses (network-specific!) |
+| Version report | `releaseData/versionReports/releaseN-report.json` | Contract changes & version deltas |
+| Init data | `releaseData/initializationData/releaseN.json` | Constructor args for new contracts |
+| Proposal | `proposal-*.json` | Governance transactions |
+
+**Important**: `libraries.json` is network-specific. Regenerate when switching between Celo Sepolia and Mainnet.
+
+## Determining Release Numbers
+
+**Priority**: Always prefer git tags over branches. Post-audit tags are preferred over base tags.
+
+```bash
+# List existing tags (check these FIRST)
+git tag -l 'core-contracts.*' | sort -V | tail -15
+
+# List release branches (fallback if no tag exists)
+git branch -a | grep 'release/core-contracts'
+```
+
+**Tag priority (check in order, use first match):**
+1. `core-contracts.vN.post-audit` or `core-contracts.vN.post_audit` - Post-audit (if exists)
+2. `core-contracts.vN` - Base tag
+3. `release/core-contracts/N` - Branch (fallback only)
+
+**Note**: Not all releases have post-audit tags. Use it if available, otherwise use the base tag.
+
+**Selection logic:**
+1. For NEW release: Check for post-audit tag first, then base tag, then branch
+2. For PREVIOUS release: Same logic - use post-audit tag if available, otherwise base tag
+
+## Starting a Local Fork
+
+Before testing on a local fork, start Anvil with the required parameters:
+
+```bash
+# Fork Celo Sepolia
+anvil --fork-url https://forno.celo-sepolia.celo-testnet.org \
+  --code-size-limit 500000 \
+  --gas-limit 100000000
+
+# Fork Mainnet
+anvil --fork-url https://forno.celo.org \
+  --code-size-limit 500000 \
+  --gas-limit 100000000
+```
+
+**Important**: The `--code-size-limit` and `--gas-limit` flags are required for Celo contract deployments due to large contract sizes.
+
+## Contract Verification
+
+The release script automatically verifies deployed contracts on:
+- **Blockscout** (https://celo-sepolia.blockscout.com or https://celo.blockscout.com) - No API key required
+- **Celoscan** via Etherscan V2 API (https://celoscan.io) - **API key required** for production networks
+
+### Verification Features
+
+The script handles verification automatically with:
+- **Linked libraries**: Contracts using libraries (e.g., Governance with Proposals library) are verified with the `--libraries` flag
+- **Foundry profiles**: Sets `FOUNDRY_PROFILE` environment variable (`truffle-compat` for 0.5.x, `truffle-compat8` for 0.8.x) to ensure bytecode matches
+- **Full compiler version**: Uses full version with commit hash (e.g., `0.5.14+commit.01f1aaa4`)
+
+### Celoscan API Key (Required for celo-sepolia and mainnet)
+
+The API key is **required by default** for production networks. Get your key from https://etherscan.io/myapikey
+
+**Setup options (in order of precedence):**
+
+1. **CLI flag**: `-a YOUR_API_KEY`
+2. **Environment variable**: `export CELOSCAN_API_KEY=YOUR_API_KEY`
+3. **Config file**: `packages/protocol/.env.json`
+   ```json
+   {
+     "celoScanApiKey": "YOUR_API_KEY"
+   }
+   ```
+
+**Note**: The Etherscan V2 API uses a unified endpoint (`api.etherscan.io`) that works with a single API key for all supported chains including Celo.
+
+### Skip Verification
+
+To skip verification (e.g., for testing or if you don't have an API key):
+```bash
+yarn release:make:foundry ... -s
+```
+
+Verification is automatically skipped when using a custom RPC URL (local forks).
+
+### Verification Troubleshooting
+
+- **"Address is not a smart-contract"**: Block explorer hasn't indexed the contract yet. The script waits 30s initially, then automatically retries up to 6 times with logarithmic delays (5s, 10s, 20s, 40s, 60s max).
+- **"Bytecode mismatch"**: Usually caused by wrong foundry profile. The script now automatically sets `FOUNDRY_PROFILE` based on contract source path.
+- **Linked library errors**: The script automatically detects and passes library addresses via `--libraries` flag for contracts that use linked libraries.
+
+## Common Issues
+
+### "libraries.json not found"
+Run `verify-deployed:foundry` first with the previous release tag.
+
+### "Version mismatch detected"
+Update `getVersionNumber()` in the contract to match expected version from the report.
+
+### "Deployment reverted" or "Out of gas" on Local Fork
+Ensure Anvil is started with `--code-size-limit 500000 --gas-limit 100000000`.
+
+### Testing on Local Fork
+Use anvil's default test key for local forks:
+```
+0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
+```
