### Summary - Implement native token transfers from DataHaven to Ethereum using Snowbridge infrastructure - Add comprehensive datahaven-native-transfer pallet with lock-and-mint mechanism for cross-chain token representation ### Key Features **New Pallet: datahaven-native-transfer** - Cross-chain transfers: Transfer DataHaven native tokens to Ethereum addresses via `transfer_to_ethereum extrinsic` - Token locking mechanism: Secure token storage in deterministic Ethereum sovereign account during transfers - Fee management: Required fees for all transfers to compensate relayers and prevent spam - Emergency controls: Pause/unpause functionality - Token registration: Integration with Snowbridge's token registration for native token identification <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Introduced the DataHaven Native Transfer pallet enabling secure cross-chain transfers of DataHaven native tokens to and from Ethereum via Snowbridge. - Added token locking on DataHaven, minting on Ethereum, and mandatory fee collection to cover gas costs and incentivize relayers. - Implemented pause and unpause controls for emergency management of token transfers. - **Configuration** - Integrated the new pallet into mainnet, stagenet, and testnet runtimes with updated network, account, and treasury settings. - Added Ethereum sovereign account constants and native token ID support for optimized cross-chain operations. - **Documentation** - Added comprehensive README and inline documentation detailing pallet features, extrinsics, events, errors, and security considerations. - **Tests** - Added extensive unit and integration tests covering token transfers, native token registration, fee handling, pause functionality, and event validation across all supported networks. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: Steve Degosserie <723552+stiiifff@users.noreply.github.com>
