+# Facilitator Instructions: MCM Bridge Unpause
+
+## Overview
+
+As a Facilitator, you are responsible for:
+1. Preparing the bridge unpause configuration
+2. Creating the MCM proposal
+3. Committing and pushing the proposal to the repo
+4. Coordinating with Signers
+5. Collecting signatures
+6. Executing the proposal on-chain
+
+## Prerequisites
+
+```bash
+cd contract-deployments
+git pull
+cd solana/devnet-alpha/2025-10-23-mcm-unpause-bridge
+make deps
+```
+
+Ensure you have:
+- `mcmctl` installed (via `make deps`)
+- `eip712sign` installed (via `make deps`)
+- A funded Solana wallet configured
+
+## Phase 1: Prepare and Generate Proposal
+
+### 1.1. Update .env with bridge unpause configuration
+
+Set the following in `.env`:
+
+```bash
+MCM_PROGRAM_ID=<mcm-program-id>
+MCM_MULTISIG_ID=<multisig-id>
+MCM_VALID_UNTIL=<unix-timestamp>
+MCM_OVERRIDE_PREVIOUS_ROOT=false  # or true if needed
+MCM_PROPOSAL_OUTPUT=proposal.json
+
+# Bridge configuration
+BRIDGE_PROGRAM_ID=<bridge-program-id>
+PAUSED=false  # or true to pause
+```
+
+### 1.2. Generate proposal
+
+```bash
+make step1-create-proposal
+```
+
+This creates the proposal file (default `proposal.json` or whatever is set in `MCM_PROPOSAL_OUTPUT`).
+
+### 1.3. Review proposal
+
+Open and review the generated proposal file to verify:
+- Bridge program ID is correct
+- Pause status is correct (unpausing)
+- Valid until timestamp is appropriate
+
+### 1.4. Commit and push
+
+```bash
+git add .
+git commit -m "Add MCM bridge unpause proposal"
+git push
+```
+
+## Phase 2: Coordinate with Signers and Collect Signatures
+
+Coordinate with Signers to collect their signatures. Each Signer will run `make sign` and provide their signature.
+
+Concatenate all signatures in the format: `0xSIG1,0xSIG2,0xSIG3`
+
+Once you have all required signatures, update `.env`:
+
+```bash
+MCM_SIGNATURES_COUNT=<number-of-signatures>
+MCM_SIGNATURES=0xSIG1,0xSIG2,0xSIG3
+```
+
+## Phase 3: Execute Proposal
+
+```bash
+make step3-execute-proposal
+```
+
+This command executes all the necessary steps:
+- Initialize signatures account
+- Append signatures
+- Finalize signatures
+- Set root
+- Execute proposal
+
+## Phase 4: Verification
+
+### 4.1. View transaction on Solana Explorer
+
+Visit the Solana Explorer for your network:
+- Mainnet: https://explorer.solana.com/
+- Devnet: https://explorer.solana.com/?cluster=devnet
+
+Search for the execution transaction and verify:
+- The transaction was successful
+- The program logs show `Instruction: SetPauseStatus` (Anchor log)
+- The pause status matches the intended action (unpaused)
+
+### 4.2. Update README
+
+Update the Status line in README.md to:
+
+```markdown
+Status: [EXECUTED](https://explorer.solana.com/tx/<transaction-signature>?cluster=<network>)
+```
+
+Replace `<transaction-signature>` with the execution transaction signature and `<network>` with the appropriate cluster (devnet, mainnet-beta, etc.).

+# MCM Bridge Unpause
+
+Status: [EXECUTED](https://solscan.io/tx/2a23mhJfhs9uqrbXf7FvqgL38A5GgTUycqFWxXhiaMY6k8PD5YtSSe2EX9QXfH4cpJtsS8TPvXp9ep1AnBsgt8Qs?cluster=devnet)
+
+## Description
+
+This task unpauses the Bridge program using the MCM program. This is a critical security operation that can be used to halt bridge operations in emergency situations.
+
+## Procedure for Signers
+
+### 1. Update repo
+
+```bash
+cd contract-deployments
+git pull
+cd solana/devnet-alpha/2025-10-23-mcm-unpause-bridge
+make deps
+```
+
+### 2. Setup Ledger
+
+Your Ledger needs to be connected and unlocked. The **Ethereum application** needs to be opened on Ledger with the message "Application is ready".
+
+### 3. Sign the proposal
+
+```bash
+make sign
+```
+
+This command will:
+1. Display the proposal hash
+2. Prompt you to sign on your Ledger
+3. Output your signature
+
+**Verify on your Ledger**: Check that the data you're signing matches the proposal hash displayed in the terminal.
+
+After signing, you will see output like:
+
+```
+Signature: 1234567890abcdef...
+```
+
+### 4. Send signature to Facilitator
+
+Copy the **entire signature** and send it to the Facilitator via your secure communication channel.
+
+**That's it!** The Facilitator will collect all signatures and execute the proposal.
+
+## For Facilitators
+
+See [FACILITATORS.md](./FACILITATORS.md) for complete instructions on preparing, executing, and verifying this task.
