func GetTransactionExecute added in v0.22.0 

func GetTransactionExecute(builder *CallBuilder[gethcommon.Hash, RpcTransaction], rpc *EncryptionManager) error

func GetTransactionReceiptExecute added in v0.22.0 

func GetTransactionReceiptExecute(builder *CallBuilder[gethcommon.Hash, map[string]interface{}], rpc *EncryptionManager) error

func SubmitTxExecute(builder *CallBuilder[common.L2Tx, gethcommon.Hash], rpc *EncryptionManager) error

func SubmitTxValidate added in v0.22.0 

func SubmitTxValidate(reqParams []any, builder *CallBuilder[common.L2Tx, gethcommon.Hash], _ *EncryptionManager) error

func TenCallExecute added in v0.22.0 

func TenCallExecute(builder *CallBuilder[CallParamsWithBlock, string], rpc *EncryptionManager) error

func TenCallValidate added in v0.22.0 

func TenCallValidate(reqParams []any, builder *CallBuilder[CallParamsWithBlock, string], _ *EncryptionManager) error

func WithVKEncryption added in v0.22.0 

func WithVKEncryption[P any, R any](
	encManager *EncryptionManager,
	encReq []byte,
	validate func([]any, *CallBuilder[P, R], *EncryptionManager) error,
	execute func(*CallBuilder[P, R], *EncryptionManager) error,
) (*responses.EnclaveResponse, common.SystemError)

WithVKEncryption - handles the decryption, VK, and encryption P - the type of the temporary parameter calculated after phase 1 R - the type of the result validate - extract and validate the arguments execute - execute the user call only after authorising. Make sure to return a default value that makes sense in case of NotAuthorised note - authorisation is specific to each call e.g. - "getTransaction" or "getBalance" have to perform authorisation "Ten_call" , "Estimate_Gas" - have to authenticate the "From" - which will be used by the EVM

Types
