Status	Deployed

Transfers the EVM call value to the Substrate account supplied as a 32-byte public key.

Functions

Function	Mutability
`transfer(bytes32)`	`payable`

Added operations

Function	Source extrinsic
`transferKeepAlive`	`Balances.transfer_keep_alive`
`transferAll`	`Balances.transfer_all`

The existing transfer(bytes32) semantically covers Balances.transfer_allow_death by taking the amount from attached EVM value. The added functions use explicit typed arguments where attached value does not express the complete source operation. They dispatch the highest-level Balances call as the mapped signer. force_transfer requires Root and the feature-gated development faucet is not part of the production interface.
