Router Functions

Core Functions

ccipSend()

Sends a CCIP message to a destination chain.

Parameters:

• destinationChainSelector: uint64 - Destination chain selector
• receiver: address - Receiver address on destination chain
• data: bytes - Message data
• feeToken: address - Token to pay fees with (LINK or native ETH)
• extraArgs: bytes - Additional arguments

getFee()

Gets the fee for sending a CCIP message.

Parameters:

• destinationChainSelector: uint64 - Destination chain selector
• data: bytes - Message data

Returns: uint256 - Fee amount in fee token

getOnRamp()

Gets the OnRamp address for a destination chain.

Parameters:

• destinationChainSelector: uint64 - Destination chain selector

Returns: address - OnRamp contract address

Integration with Other Contracts

CCIP Sender

• Address: 0x105F8A15b819948a89153505762444Ee9f324684
• Relationship: Sender contract interacts with Router to send messages

Bridge Contracts

• CCIPWETH9Bridge: 0x89dd12025bfCD38A168455A44B400e913ED33BE2
• CCIPWETH10Bridge: 0xe0E93247376aa097dB308B92e6Ba36bA015535D0
• Relationship: Bridge contracts call Router to send cross-chain messages

Verification

Verify Router Deployment

./scripts/verify-ccip-router.sh

Check Router Status

cast code 0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e --rpc-url http://192.168.11.250:8545

Get Fee Token

cast call 0x8078A09637e47Fa5Ed34F626046Ea2094a5CDE5e "getFeeToken()" --rpc-url http://192.168.11.250:8545

Configuration Status

Component	Status	Notes
Router Deployment	✅ Complete	Contract deployed and verified
Fee Configuration	✅ Complete	LINK token configured
OnRamp Mapping	⚠️ Unknown	Cannot verify without admin access
Destination Allowlist	⚠️ Unknown	Cannot verify without admin access

Troubleshooting

Router Not Responding

1. Check RPC endpoint connectivity
2. Verify Router contract address
3. Check network status

Fee Calculation Failing

1. Verify LINK token balance
2. Check fee token configuration
3. Verify destination chain selector

Message Not Routing

1. Verify destination chain selector
2. Check OnRamp configuration
3. Verify destination allowlist
