### Summary - **Add** `test/suites/native-token-transfer.test.ts` focused on the HAVE native token lifecycle via Snowbridge v2. - **Validate** registration, DataHaven → Ethereum mints, Ethereum → DataHaven unlocks, event emission, and 1:1 backing invariant. ### Tests added - should register DataHaven native token on Ethereum - should transfer tokens from DataHaven to Ethereum - should maintain 1:1 backing ratio - should emit transfer events - should transfer tokens from Ethereum to DataHaven (Snowbridge v2) ### What the suite covers - **Registration**: Sudo-registers the native token; confirms `ForeignTokenRegistered` on the Gateway; verifies ERC-20 metadata (`HAVE`/`wHAVE`, 18 decimals). - **DataHaven → Ethereum**: Executes `transfer_to_ethereum`; asserts Substrate events (`TokensLocked`, `TokensTransferredToEthereum`); observes Ethereum `Transfer` mint (from zero address); validates sender balance delta, sovereign account increase, and ERC-20 recipient credit. - **Backing invariant**: Ensures sovereign account balance ≥ ERC-20 total supply. - **Event emission**: Confirms key Substrate events without polling delays. - **Ethereum → DataHaven**: Approves and calls `Gateway.sendToken`; if unsupported locally, the test skips; otherwise asserts burn on Ethereum and unlock on DataHaven with corresponding balance deltas. --------- Co-authored-by: Steve Degosserie <723552+stiiifff@users.noreply.github.com>
