+# Bridge Scripts
+
+Scripts for bridging EigenLayer operator state from L1 to L2.
+
+## bridge-to-l2.sh
+
+Deploys bridge contracts and bridges operator state from an L1 registry coordinator to an L2 mimic contract using mock SP1Helios verification.
+
+### Prerequisites
+
+- [Foundry](https://book.getfoundry.sh/getting-started/installation) installed
+- `cast` and `forge` available in PATH
+- `jq` installed
+
+### Usage
+
+```bash
+# Set required environment variables
+export PRIVATE_KEY="0x..."
+export L1_RPC_URL="https://eth-sepolia.g.alchemy.com/v2/YOUR_KEY"
+export L2_RPC_URL="https://gnosis-mainnet.g.alchemy.com/v2/YOUR_KEY"
+export REGISTRY_COORDINATOR_ADDRESS="0x..."
+
+# Run the bridge script
+./scripts/bridge-to-l2.sh
+```
+
+Or use an env file:
+
+```bash
+cp scripts/bridge.env.example scripts/bridge.env
+# Edit bridge.env with your values
+source scripts/bridge.env && ./scripts/bridge-to-l2.sh
+```
+
+### What it does
+
+1. **Deploy L1 Contracts** - Deploys `MiddlewareShim` pointing to the registry coordinator
+2. **Deploy L2 Contracts** - Deploys `SP1HeliosMock`, `RegistryCoordinatorMimic`, `BLSSignatureChecker`
+3. **Update L1 Shim** - Calls `updateMiddlewareDataHash()` to snapshot operator state
+4. **Generate Mock Proof** - Creates storage/account proofs and sets state root on mock
+5. **Bridge State** - Runs `UpdateMimic.s.sol` to bridge state to L2
+
+### Skip Deployment
+
+To use existing deployed contracts:
+
+```bash
+export SKIP_DEPLOY=true
+export L1_DEPLOY_FILE=/path/to/l1-deploy.json
+export L2_DEPLOY_FILE=/path/to/l2-deploy.json
+./scripts/bridge-to-l2.sh
+```
+
+### Output
+
+The script creates these files in `contracts/artifacts/`:
+- `l1-deploy.json` - L1 contract addresses
+- `l2-deploy.json` - L2 contract addresses
+- `middlewareDataProof.json` - Generated storage proof
