# Runbook: Deploy cW* and Wire Config

**Created:** 2026-02-27  
**Purpose:** Steps to deploy cWUSDT/cWUSDC on a chain, set `CW_BRIDGE_<CHAIN>`, update token-mapping, and verify roles. Covers Phase D and E from [CW_BRIDGE_TASK_LIST.md](../00-meta/CW_BRIDGE_TASK_LIST.md).

---

## Prerequisites

- `smom-dbis-138/.env` has `CW_BRIDGE_<CHAIN>` set (already done from deployed bridge suite for Mainnet, Cronos, BSC, Polygon, Gnosis, Avalanche, Base, Arbitrum, Optimism).
- For **cross-chain mint** to work, the bridge at that address must either be extended to mint cW* in `ccipReceive` or you must deploy a dedicated cW* receiver (e.g. TwoWayTokenBridgeL2) and point `CW_BRIDGE_<CHAIN>` to it; see [CW_BRIDGE_APPROACH.md](CW_BRIDGE_APPROACH.md).
- RPC URL and `PRIVATE_KEY` for the target chain(s).

### Optional hard-peg deployment knobs

`DeployCWTokens.s.sol` now supports:

- `CW_STRICT_MODE=1` — revoke deployer `MINTER_ROLE` / `BURNER_ROLE` after granting the bridge
- `CW_GOVERNANCE_ADMIN=0x...` — grant `DEFAULT_ADMIN_ROLE` to governance; in strict mode the deployer admin role is revoked when this is set
- `CW_FREEZE_OPERATIONAL_ROLES=1` — freeze future `MINTER_ROLE` / `BURNER_ROLE` changes on the token after setup

For production hard-peg rollouts, use at least `CW_STRICT_MODE=1`.

### Strict bridge hard-peg requirements

If you are using [`CWMultiTokenBridgeL1.sol`](../../smom-dbis-138/contracts/bridge/CWMultiTokenBridgeL1.sol) and [`CWMultiTokenBridgeL2.sol`](../../smom-dbis-138/contracts/bridge/CWMultiTokenBridgeL2.sol) for `cWUSDC` / `cWUSDT`, strict mode now also means:

- L1 must explicitly allowlist the canonical token with `configureSupportedCanonicalToken(token, true)`
- L1 should set a per-destination ceiling with `setMaxOutstanding(token, chainSelector, amount)` unless you intentionally want unlimited capacity
- L1 should attach [`CWReserveVerifier.sol`](../../smom-dbis-138/contracts/bridge/integration/CWReserveVerifier.sol) so new outbound wraps are blocked when canonical backing is unsafe
- L2 token pairs and destination peers should be frozen after wiring with `freezeTokenPair(canonicalToken)` and `freezeDestination(chainSelector)`
- Admin withdrawal of supported canonical escrow is blocked while funds are locked, so “rescue” flows must use the bridge or pause process instead of `withdrawToken`

Operational note: the verifier gates new `lockAndSend` mints. Return `ccipReceive` releases on Chain 138 are intentionally left live so users are not trapped in wrapped positions during a reserve incident.

---

## Phase D: Deploy cW* and wire config

**One-command helper (from repo root):**  
`./scripts/deployment/run-cw-remaining-steps.sh` runs a dry-run and `--update-mapping` by default. Use `--deploy` to broadcast, then set CWUSDT_*/CWUSDC_* in .env from output and run again with `--update-mapping` (or run `--update-mapping` after editing .env). Use `--verify` to check MINTER/BURNER roles per chain and `--verify-hard-peg` to inspect the Avalanche hard-peg bridge state (`supportedCanonicalToken`, `maxOutstanding`, verifier attachment/config, and L2 freeze flags).

### D1. Run cW* deploy

**All supported chains:**

```bash
cd smom-dbis-138
./scripts/deployment/deploy-tokens-and-weth-all-chains-skip-canonical.sh --deploy-cw
```

Or from repo root (runs same deploy, then can run update-mapping/verify):

```bash
./scripts/deployment/run-cw-remaining-steps.sh --deploy
```

**Single chain (e.g. BSC 56):**

```bash
cd smom-dbis-138
source .env
# Use the per-chain bridge; script will pick CW_BRIDGE_BSC when running for chain 56
CW_BRIDGE_ADDRESS="$CW_BRIDGE_BSC" forge script script/deploy/DeployCWTokens.s.sol:DeployCWTokens \
  --rpc-url "$BSC_RPC_URL" --chain-id 56 --broadcast --private-key "$PRIVATE_KEY" --legacy
```

**Strict production example:**

```bash
cd smom-dbis-138
source .env
CW_STRICT_MODE=1 \
CW_GOVERNANCE_ADMIN=0xYourMultisig \
CW_BRIDGE_ADDRESS="$CW_BRIDGE_BSC" forge script script/deploy/DeployCWTokens.s.sol:DeployCWTokens \
  --rpc-url "$BSC_RPC_URL" --chain-id 56 --broadcast --private-key "$PRIVATE_KEY" --legacy
```

Or with the wrapper (target one chain only if the script supports `--chain 56`):

```bash
./scripts/deployment/deploy-tokens-and-weth-all-chains-skip-canonical.sh --deploy-cw --chain 56
```

Record the printed addresses for **cWUSDT** and **cWUSDC** per chain.

### D2. Set CWUSDT_<CHAIN> and CWUSDC_<CHAIN> in .env

Append or update in `smom-dbis-138/.env` (replace with actual addresses from D1 output):

```bash
# Example for BSC (56)
CWUSDT_BSC=0x...
CWUSDC_BSC=0x...

# Example for Polygon (137)
CWUSDT_POLYGON=0x...
CWUSDC_POLYGON=0x...
```

Use the chain suffix that matches the deploy script: MAINNET, CRONOS, BSC, POLYGON, GNOSIS, AVALANCHE, BASE, ARBITRUM, OPTIMISM.

### D3. Update token-mapping-multichain.json

**Automated:** After setting `CWUSDT_<CHAIN>` and `CWUSDC_<CHAIN>` in `smom-dbis-138/.env`, run from repo root:

```bash
./scripts/deployment/run-cw-remaining-steps.sh --update-mapping
```

This updates `config/token-mapping-multichain.json` for all chains that have `CWUSDT_*`/`CWUSDC_*` in .env (138→chain pairs; Compliant_USDT_cW, Compliant_USDC_cW, and Compliant_EURC_cW if `CWEURC_*` is set).

**Manual:** For each chain where cW* was deployed, set `addressTo` for the `_cW` entries (replace the `0x0` placeholder) in `config/token-mapping-multichain.json`: Compliant_USDT_cW → CWUSDT_<CHAIN>, Compliant_USDC_cW → CWUSDC_<CHAIN>, Compliant_EURC_cW if cWEURC deployed.

### D3b. Update the active GRU Transport overlay

After the mapping is correct, confirm or update [`config/gru-transport-active.json`](../../config/gru-transport-active.json):

- ensure the destination chain is enabled
- ensure the `transportPairs` entry points at the correct `peerKey`
- ensure `maxOutstanding` policy is set for the pair
- ensure the reserve-verifier reference is correct for hard-peg pairs
- leave public pools inactive until they are actually deployed and recorded in `deployment-status.json`

### D4. Verify on-chain

Confirm the bridge/receiver has MINTER_ROLE and BURNER_ROLE on the cW* token:

```bash
# MINTER_ROLE = keccak256("MINTER_ROLE")
cast keccak "MINTER_ROLE"
# Example: 0x...

# Check cWUSDT on BSC (replace addresses and rpc)
cast call <CWUSDT_BSC> "hasRole(bytes32,address)(bool)" $(cast keccak "MINTER_ROLE") $CW_BRIDGE_BSC --rpc-url $BSC_RPC_URL
cast call <CWUSDT_BSC> "hasRole(bytes32,address)(bool)" $(cast keccak "BURNER_ROLE") $CW_BRIDGE_BSC --rpc-url $BSC_RPC_URL
```

Both should return `true`.

### D5. Configure strict escrow bridge state

For hard-peg deployments using `CWMultiTokenBridgeL1` / `CWMultiTokenBridgeL2`, wire the bridge state after roles are verified.

Example on Chain 138 for `cUSDC -> cWUSDC` on Avalanche:

```bash
cd smom-dbis-138 && source .env

# Allowlist the canonical token on the 138-side escrow bridge
cast send "$CHAIN138_L1_BRIDGE" "configureSupportedCanonicalToken(address,bool)" "$CUSDC_138" true \
  --rpc-url "$RPC_URL_138" --private-key "$PRIVATE_KEY" --legacy

# Optional but recommended: cap how much this destination can keep outstanding
cast send "$CHAIN138_L1_BRIDGE" "setMaxOutstanding(address,uint64,uint256)" "$CUSDC_138" 6433500567565415381 1000000000000 \
  --rpc-url "$RPC_URL_138" --private-key "$PRIVATE_KEY" --legacy
```

Example on the destination chain:

```bash
cd smom-dbis-138 && source .env

# Freeze the token pair once canonical -> wrapped mapping is correct
cast send "$AVAX_CW_BRIDGE" "freezeTokenPair(address)" "$CUSDC_138" \
  --rpc-url "$AVALANCHE_RPC_URL" --private-key "$PRIVATE_KEY" --legacy

# Freeze the Chain 138 peer once the bridge address is confirmed
cast send "$AVAX_CW_BRIDGE" "freezeDestination(uint64)" 138 \
  --rpc-url "$AVALANCHE_RPC_URL" --private-key "$PRIVATE_KEY" --legacy
```

Recommended verification calls:

```bash
cast call "$CHAIN138_L1_BRIDGE" "supportedCanonicalToken(address)(bool)" "$CUSDC_138" --rpc-url "$RPC_URL_138"
cast call "$CHAIN138_L1_BRIDGE" "maxOutstanding(address,uint64)(uint256)" "$CUSDC_138" 6433500567565415381 --rpc-url "$RPC_URL_138"
cast call "$AVAX_CW_BRIDGE" "tokenPairFrozen(address)(bool)" "$CUSDC_138" --rpc-url "$AVALANCHE_RPC_URL"
cast call "$AVAX_CW_BRIDGE" "destinationFrozen(uint64)(bool)" 138 --rpc-url "$AVALANCHE_RPC_URL"
```

For the production Avalanche route, `smom-dbis-138/scripts/deployment/complete-nonprefunded-avax-cutover.sh` now applies these controls directly from env:

- `CW_MAX_OUTSTANDING_USDT_AVALANCHE`
- `CW_MAX_OUTSTANDING_USDC_AVALANCHE`
- `CW_FREEZE_AVAX_L2_CONFIG`

### D6. Deploy and attach the canonical reserve verifier

Use the helper script in `smom-dbis-138/script/DeployCWReserveVerifier.s.sol` to deploy the verifier and optionally attach it to `CWMultiTokenBridgeL1`.

Example:

```bash
cd smom-dbis-138 && source .env

CW_L1_BRIDGE="$CHAIN138_L1_BRIDGE" \
CW_STABLECOIN_RESERVE_VAULT="$STABLECOIN_RESERVE_VAULT" \
CW_RESERVE_SYSTEM="$RESERVE_SYSTEM" \
CW_CANONICAL_USDT="$CUSDT_138" \
CW_CANONICAL_USDC="$CUSDC_138" \
CW_USDT_RESERVE_ASSET=0xOfficialUSDTReserveAsset \
CW_USDC_RESERVE_ASSET=0xOfficialUSDCReserveAsset \
forge script script/DeployCWReserveVerifier.s.sol:DeployCWReserveVerifier \
  --rpc-url "$RPC_URL_138" --broadcast --private-key "$PRIVATE_KEY" --legacy
```

The script defaults to:

- attaching the verifier to the L1 bridge
- requiring vault backing when `CW_STABLECOIN_RESERVE_VAULT` is set
- requiring reserve-system balance checks when `CW_RESERVE_SYSTEM` is set
- requiring canonical token ownership to match the reserve vault when a vault is set

Recommended post-deploy verification:

```bash
cast call "$CHAIN138_L1_BRIDGE" "reserveVerifier()(address)" --rpc-url "$RPC_URL_138"
cast call <CW_RESERVE_VERIFIER> "verifyLock(address,uint64,uint256)(bool)" "$CUSDC_138" 6433500567565415381 1 --rpc-url "$RPC_URL_138"
cast call <CW_RESERVE_VERIFIER> "getVerificationStatus(address,uint64)((bool,bool,bool,bool,bool,bool,bool,bool,uint256,uint256,uint256,uint256,uint256,uint256,uint256,uint256))" "$CUSDC_138" 6433500567565415381 --rpc-url "$RPC_URL_138"
```

For the production Avalanche route, `smom-dbis-138/scripts/deployment/complete-nonprefunded-avax-cutover.sh` now also reads and converges:

- `CW_RESERVE_VERIFIER_CHAIN138`
- `CW_STABLECOIN_RESERVE_VAULT`
- `CW_RESERVE_SYSTEM`
- `CW_ATTACH_VERIFIER_TO_L1`
- `CW_REQUIRE_VAULT_BACKING`
- `CW_REQUIRE_RESERVE_SYSTEM_BALANCE`
- `CW_REQUIRE_TOKEN_OWNER_MATCH_VAULT`
- `CW_CANONICAL_USDT`
- `CW_CANONICAL_USDC`
- `CW_USDT_RESERVE_ASSET`
- `CW_USDC_RESERVE_ASSET`

---

## Phase E: Relay and send path (138 → other chains)

### E1. Relay service (138 → Mainnet)

If using the existing CCIPRelayBridge for cW* on Mainnet, that contract is WETH-only and must be **extended** (or a separate cW* receiver deployed and relay logic updated) so that when the relay sends a cUSDT/cUSDC message, the Mainnet receiver mints cWUSDT/cWUSDC. See [RELAY_BRIDGE_ADD_LINK_SUPPORT_RUNBOOK.md](RELAY_BRIDGE_ADD_LINK_SUPPORT_RUNBOOK.md) for the pattern (token whitelist + transfer or mint in `ccipReceive`). Then:

- Configure relay to send c* messages to the cW* receiver on Mainnet.
- Ensure the receiver has MINTER_ROLE on cWUSDT/cWUSDC and holds or mints as designed.

### E2. Direct CCIP (138 → chain)

If Chain 138 uses UniversalCCIPBridge or a dedicated sender to send c* to a destination chain:

- Add destination config for the c* token with **receiver** = the cW* receiver on the destination (e.g. TwoWayTokenBridgeL2 address).
- Ensure the receiver on the destination has MINTER_ROLE on the cW* token and implements `ccipReceive` → `cW*.mint(recipient, amount)` (see [CW_BRIDGE_APPROACH.md](CW_BRIDGE_APPROACH.md)).

### E3. Test E2E

1. On Chain 138: Lock or transfer cUSDT to the sender/bridge and trigger a send to the target chain (recipient = test address).
2. Wait for CCIP execution on the destination chain.
3. On the destination chain: Verify the recipient’s cWUSDT balance increased (e.g. `cast call <CWUSDT_<CHAIN>> "balanceOf(address)(uint256)" <recipient> --rpc-url <RPC>`).

---

## New chain checklist (summary)

| Step | Action |
|------|--------|
| 1 | Set `CW_BRIDGE_<CHAIN>` in .env (or use existing from bridge suite). |
| 2 | Run DeployCWTokens for that chain (D1). |
| 3 | Set `CWUSDT_<CHAIN>`, `CWUSDC_<CHAIN>` in .env (D2). |
| 4 | Update `config/token-mapping-multichain.json` `addressTo` for _cW entries (D3). |
| 4a | Confirm `config/gru-transport-active.json` activation and policy refs for the new chain (D3b). |
| 5 | Verify MINTER_ROLE and BURNER_ROLE on cW* for the bridge (D4). |
| 6 | In hard-peg mode, allowlist canonical tokens and set `maxOutstanding` on `CWMultiTokenBridgeL1`, then freeze token pair and destination on `CWMultiTokenBridgeL2` (D5). |
| 7 | Deploy and attach `CWReserveVerifier`, then configure canonical `cUSDT` / `cUSDC` backing requirements (D6). |
| 8 | If cross-chain mint is required, ensure the bridge/receiver code mints cW* in ccipReceive (Phase B or C); then wire relay/direct CCIP (E1, E2) and run E2E test (E3). |

## Retry failed cW* deploys (Mainnet, Cronos, Arbitrum)

If the 10 remaining cW* (cWEURC..cWXAUT) failed on **Mainnet** (nonce), **Cronos** (RPC timeout), or **Arbitrum** (gas), use the steps below.

### Mainnet (1) — fix nonce

Deployer nonce on Mainnet must match the RPC (error: `nonce=256 maxNonce=253` means 3 pending txs are ahead of what the RPC has confirmed).

1. **Check nonce and balance:**  
   `./scripts/deployment/check-deployer-nonce-and-balance.sh`

2. **Options:**  
   - **Wait** for pending transactions to confirm, then re-run the deploy.  
   - **Replace/cancel** pending txs: send a 0-value transaction from the deployer to itself with the *next expected nonce* (e.g. 253) and higher gas so it replaces the stuck one; repeat until the queue is cleared.  
   - Use the same wallet in another tool (e.g. MetaMask) and ensure no other process is sending from this account.

3. **Run deploy** once nonce is aligned:

```bash
cd smom-dbis-138 && source .env
DEPLOY_CWUSDT=0 DEPLOY_CWUSDC=0 CW_BRIDGE_ADDRESS="$CW_BRIDGE_MAINNET" forge script script/deploy/DeployCWTokens.s.sol:DeployCWTokens \
  --rpc-url "${ETHEREUM_MAINNET_RPC}" --chain-id 1 --broadcast --private-key "$PRIVATE_KEY" --legacy -vvv
```

Add the printed CWEURC_MAINNET … CWXAUT_MAINNET to `.env`, then run `./scripts/deployment/run-cw-remaining-steps.sh --update-mapping`.

### Cronos (25) — retry when RPC is stable; fix nonce if needed

If you see `invalid nonce; got X, expected Y`, wait for pending txs to confirm or replace/cancel them (same idea as Mainnet). Check: `./scripts/deployment/check-deployer-nonce-and-balance.sh`

```bash
cd smom-dbis-138 && source .env
DEPLOY_CWUSDT=0 DEPLOY_CWUSDC=0 CW_BRIDGE_ADDRESS="$CW_BRIDGE_CRONOS" forge script script/deploy/DeployCWTokens.s.sol:DeployCWTokens \
  --rpc-url "${CRONOS_RPC_URL}" --chain-id 25 --broadcast --private-key "$PRIVATE_KEY" --legacy -vvv
```

Then set CWEURC_CRONOS … CWXAUT_CRONOS in `.env` from the script output and run `--update-mapping`.

### Arbitrum (42161) — use current gas; low gas price is enough

[Arbitrum One gas](https://arbiscan.io/gastracker) is often ~0.02 Gwei; the 10-contract deploy then costs &lt;0.001 ETH. If you see "max fee per gas less than block base fee", set `ARBITRUM_GAS_PRICE` slightly above base (e.g. `25000000` = 0.025 gwei). Only use 35 gwei if the network is congested. Run the deploy:

```bash
cd smom-dbis-138 && source .env
# Only if you see "max fee per gas less than block base fee" (check https://arbiscan.io/gastracker)
export ARBITRUM_GAS_PRICE=25000000
./scripts/deployment/deploy-tokens-and-weth-all-chains-skip-canonical.sh --deploy-cw --chain 42161
```

Or single-run without the script (use 25000000 = 0.025 gwei when gas is ~0.02 Gwei):

```bash
DEPLOY_CWUSDT=0 DEPLOY_CWUSDC=0 CW_BRIDGE_ADDRESS="$CW_BRIDGE_ARBITRUM" forge script script/deploy/DeployCWTokens.s.sol:DeployCWTokens \
  --rpc-url "${ARBITRUM_MAINNET_RPC}" --chain-id 42161 --broadcast --private-key "$PRIVATE_KEY" --legacy --with-gas-price 25000000 -vvv
```

Then set in `.env` (expected addresses from script when it runs):

- CWEURC_ARBITRUM=0xd6969bC19b53f866C64f2148aE271B2Dae0C58E4
- CWEURT_ARBITRUM=0x3CD9ee18db7ad13616FCC1c83bC6098e03968E66
- CWGBPC_ARBITRUM=0xBeF5A0Bcc0E77740c910f197138cdD90F98d2427
- CWGBPT_ARBITRUM=0x948690147D2e50ffe50C5d38C14125aD6a9FA036
- CWAUDC_ARBITRUM=0x58a8D8F78F1B65c06dAd7542eC46b299629A60dd
- CWJPYC_ARBITRUM=0xFb4B6Cc81211F7d886950158294A44C312abCA29
- CWCHFC_ARBITRUM=0xf9f5D0ACD71C76F9476F10B3F3d3E201F0883C68
- CWCADC_ARBITRUM=0xeE17bB0322383fecCA2784fbE2d4CD7d02b1905B
- CWXAUC_ARBITRUM=0xc9750828124D4c10e7a6f4B655cA8487bD3842EB
- CWXAUT_ARBITRUM=0x328Cd365Bb35524297E68ED28c6fF2C9557d1363

Then run `./scripts/deployment/run-cw-remaining-steps.sh --update-mapping`.
