⏳ Not Deployed to Mainnet (But Available in Codebase)

1. MirrorManager (Kaleido Mirror Pattern)

Contract Details:

• File: contracts/mirror/MirrorManager.sol
• Purpose: Registry of mirrored token/contract addresses across chains with replay protection
• Kaleido Pattern: ✅ Implements Kaleido's Mirror pattern for address registry
• Deployment Script: script/DeployMirrorManager.s.sol
• Status: ❌ NOT DEPLOYED to Mainnet
• Required Env Var: MIRROR_ADMIN (not set in .env)

Kaleido Pattern: In Kaleido's architecture, Mirror contracts maintain address mappings across chains for cross-chain contract resolution.

Contract Features:

• Cross-chain address mirroring
• Replay protection
• Pausability
• Admin-controlled

To Deploy:

forge script script/DeployMirrorManager.s.sol \
  --rpc-url $ETH_MAINNET_RPC_URL \
  --private-key $PRIVATE_KEY \
  --broadcast \
  --verify

---

2. TwoWayTokenBridgeL1

Contract Details:

• File: contracts/bridge/TwoWayTokenBridgeL1.sol
• Purpose: L1/Main chain side - locks canonical tokens and triggers CCIP message to mint on L2
• Deployment Script: script/DeployTwoWayBridge.s.sol
• Status: ❌ NOT DEPLOYED to Mainnet
• Required Env Vars:
  • CCIP_ROUTER (set)
  • CCIP_FEE_TOKEN (LINK token address)
  • BRIDGE_L1_TOKEN (canonical token on L1) - NOT SET

Contract Features:

• Token locking on L1
• CCIP message sending
• Destination chain configuration
• Replay protection

---

3. TwoWayTokenBridgeL2

Contract Details:

• File: contracts/bridge/TwoWayTokenBridgeL2.sol
• Purpose: L2/secondary chain side - mints mirrored tokens on inbound and burns on outbound
• Deployment Script: script/DeployTwoWayBridge.s.sol (deploys both L1 and L2)
• Status: ❌ NOT DEPLOYED to Mainnet
• Required Env Vars:
  • CCIP_ROUTER (set)
  • CCIP_FEE_TOKEN (LINK token address)
  • BRIDGE_L2_TOKEN (mintable token on L2) - NOT SET

Contract Features:

• Token minting on L2
• Token burning on outbound
• CCIP message handling
• Destination chain configuration

To Deploy:

# Set required environment variables first:
# BRIDGE_L1_TOKEN=<canonical_token_address>
# BRIDGE_L2_TOKEN=<mintable_token_address>

forge script script/DeployTwoWayBridge.s.sol \
  --rpc-url $ETH_MAINNET_RPC_URL \
  --private-key $PRIVATE_KEY \
  --broadcast \
  --verify

✅ Tether Contract (Kaleido Pattern)

Status: Implemented via TwoWayTokenBridge following Kaleido's Tether pattern.

Kaleido Tether Pattern:

• In Kaleido's architecture, a "Tether" contract anchors private chain state to a public Ethereum network
• Stores signed state proofs from the private chain
• Creates immutable, verifiable records of state

This Implementation:

• TwoWayTokenBridgeL1/L2 implements the Tether-like pattern
• Synchronizes state between Mainnet (L1) and Chain-138 (L2)
• Uses CCIP for secure cross-chain messaging
• Maintains token balance synchronization (lock on L1, mint on L2)

Files:

• contracts/bridge/TwoWayTokenBridgeL1.sol - L1/Mainnet side
• contracts/bridge/TwoWayTokenBridgeL2.sol - L2/Chain-138 side

See: docs/deployment/KALEIDO_TETHER_MIRROR_PATTERN.md for detailed explanation

🚀 Next Steps

To Deploy MirrorManager:

1. Set MIRROR_ADMIN in .env (multisig recommended)
2. Run deployment script
3. Verify contract on Etherscan
4. Update .env with deployed address

To Deploy TwoWayTokenBridge:

1. Set BRIDGE_L1_TOKEN in .env (canonical token address on Mainnet)
2. Set BRIDGE_L2_TOKEN in .env (mintable token address on L2/Chain-138)
3. Ensure CCIP_ROUTER and CCIP_FEE_TOKEN are set
4. Run deployment script (deploys both L1 and L2)
5. Verify contracts on Etherscan
6. Update .env with deployed addresses

📝 Notes

• All deployment scripts are available and ready to use
• Contracts are compiled and tested
• Missing environment variables are blocking deployment
• No evidence found of MirrorManager or TwoWayTokenBridge being deployed to Mainnet
• The Etherscan API query for the deployer address did not return additional contracts beyond the two CCIP bridges
