Legacy 02: ExtraArgsV2 Token Transfer (CLI `allowOutOfOrderExecution`)

This example sends a token transfer using ExtraArgsV2 from an EOA.

Script path: script/examples/Legacy02.s.sol

You can toggle allowOutOfOrderExecution via CLI arg to cover both scenarios in one script.

What You Will Do

Mint test token(s) to your EOA on the source chain.
Send token(s) using ExtraArgsV2.
Toggle out-of-order execution with a boolean CLI value.
Observe the message on CCIP Explorer.

Before You Start

Important: Keystore first

Use a local keystore account for script execution:
cast wallet import myAccount --interactive
Enter private key:
Enter password:
`myAccount` keystore was saved successfully. Address: <YOUR_EOA_ADDRESS_SHOULD_APPEAR_HERE>
This chapter assumes --account myAccount.

You do not need to deploy a receiver contract for this token-only example. Use a destination EOA as the receiver and pass GAS_LIMIT = 0.

Step 1: Get 1 CCIP-BnM Token on Source Chain

forge script script/Faucet.s.sol:Faucet \
  --rpc-url avalancheFuji \
  --account myAccount \
  --broadcast \
  --sig "run(address)" \
  <CCIP_BNM_SOURCE_TOKEN_ADDRESS>

Step 2: Send Token With ExtraArgsV2

forge script script/examples/Legacy02.s.sol:Legacy02 \
  --rpc-url avalancheFuji \
  --account myAccount \
  --broadcast \
  --sig "run(address,uint64,address,address,uint256,uint256,bool,address)" \
  <SOURCE_ROUTER> \
  <DESTINATION_CHAIN_SELECTOR> \
  <DESTINATION_EOA_ADDRESS> \
  <CCIP_BNM_SOURCE_TOKEN_ADDRESS> \
  <AMOUNT> \
  <GAS_LIMIT> \
  <ALLOW_OUT_OF_ORDER_EXECUTION> \
  <FEE_TOKEN_ADDRESS>

Parameter notes:

<AMOUNT>: token amount in token decimals (for 18 decimals, 1e18 is 1 token).
<GAS_LIMIT>: set 0 for token-only transfer to an EOA receiver. Use > 0 for contract callback.
<ALLOW_OUT_OF_ORDER_EXECUTION>: true or false.
<FEE_TOKEN_ADDRESS>: Pass the LINK token address on the source chain here. If you want to pay for CCIP fees in native coin instead, pass 0x0000000000000000000000000000000000000000
