[E2E Test] Cross-Chain Token Transfer Validation

[omarsy]

Description

Implement an end-to-end (E2E) test to validate the cross-chain token transfer functionality. This test ensures that token balances update correctly after transferring tokens between two accounts across chains.

Steps to Reproduce

1. Check Initial Balances:

   • Retrieve and verify the initial balance of Account 1 on Chain 1.
   • Retrieve and verify the initial balance of Account 2 on Chain 1.

2. Execute Token Transfer:

   • Initiate a transfer of x tokens from Account 1 on Chain 1 to Account 2 on Chain 1 via Account 1 on Chain 2.

3. Validate Post-Transfer Balances:

   • Verify the balance of Account 1 on Chain 1 is updated correctly to original_balance - x.
   • Verify the balance of Account 2 on Chain 1 is updated correctly to original_balance + x.

Expected Outcome

• Account 1 on Chain 1 has a balance reduced by the transferred x tokens.
• Account 2 on Chain 1 has a balance increased by the received x tokens.
• No errors are encountered during the cross-chain token transfer process.
