Types

type AccountRoles

type AccountRoles struct {
	Proposer    accounts.Account
	Authorizers []accounts.Account
	Payer       accounts.Account

func (AccountRoles) Signers

func (t AccountRoles) Signers() []*accounts.Account

Signers for signing the transaction, detect if all accounts are same so only return the one account.

type AddressesRoles

type AddressesRoles struct {
	Proposer    flow.Address
