Required methods

Retrieves the EGLD call value from the VM. Will return 0 in case of an ESDT transfer (cannot have both EGLD and ESDT transfer simultaneously).

Retrieves the ESDT call value from the VM. Will return 0 in case of an EGLD transfer (cannot have both EGLD and ESDT transfer simultaneously).

Returns the call value token identifier of the current call. The identifier is wrapped in a TokenIdentifier object, to hide underlying logic.

A note on implementation: even though the underlying api returns an empty name for EGLD, but the EGLD TokenIdentifier is serialized as EGLD.

Returns the nonce of the received ESDT token. Will return 0 in case of EGLD or fungible ESDT transfer.

Returns the ESDT token type. Will return “Fungible” for EGLD.

Provided methods

Will return the EGLD call value, but also fail with an error if ESDT is sent. Especially used in the auto-generated call value processing.

Will return the ESDT call value, but also fail with an error if EGLD or the wrong ESDT token is sent. Especially used in the auto-generated call value processing.

Returns both the call value (either EGLD or ESDT) and the token identifier. Especially used in the `#[payable(“*”)] auto-generated snippets. The method might seem redundant, but there is such a hook in Arwen that might be used in this scenario in the future.
