Functions

func AddressStoreKey 

func AddressStoreKey(addr crypto.Address) []byte

AddressStoreKey turn an address to key used to get it from the account store

func DeductFees 

func DeductFees(bank BankKeeperI, ctx sdk.Context, acc std.Account, fees std.Coins) sdk.Result

DeductFees deducts fees from the given account.

NOTE: We could use the CoinKeeper (in addition to the AccountKeeper, because the CoinKeeper doesn't give us accounts), but it seems easier to do this.

func DefaultSigVerificationGasConsumer 

func DefaultSigVerificationGasConsumer(
	meter store.GasMeter, sig []byte, pubkey crypto.PubKey, params Params,
) sdk.Result

DefaultSigVerificationGasConsumer is the default implementation of SignatureVerificationGasConsumer. It consumes gas for signature verification based upon the public key type. The cost is fetched from the given params and is matched by the concrete type.

func EnsureSufficientMempoolFees 

func EnsureSufficientMempoolFees(ctx sdk.Context, fee std.Fee) sdk.Result

EnsureSufficientMempoolFees verifies that the given transaction has supplied enough fees to cover a proposer's minimum fees. A result object is returned indicating success or failure.

Contract: This should only be called during CheckTx as it cannot be part of consensus.

func FeeCollectorAddress 

func FeeCollectorAddress() crypto.Address

func GetSignBytes 

func GetSignBytes(chainID string, tx std.Tx, acc std.Account, genesis bool) ([]byte, error)

GetSignBytes returns a slice of bytes to sign over for a given transaction and an account.

func GetSignerAcc 

func GetSignerAcc(ctx sdk.Context, ak AccountKeeper, addr crypto.Address) (std.Account, sdk.Result)

GetSignerAcc returns an account for a given address that is expected to sign a transaction.

func NewAnteHandler 

func NewAnteHandler(ak AccountKeeper, bank BankKeeperI, sigGasConsumer SignatureVerificationGasConsumer, opts AnteOptions) sdk.AnteHandler

NewAnteHandler returns an AnteHandler that checks and increments sequence numbers, checks signatures & account numbers, and deducts fees from the first signer.

func NewHandler 

func NewHandler(acck AccountKeeper) authHandler

NewHandler returns a handler for "auth" type messages.

func ProcessPubKey 

func ProcessPubKey(acc std.Account, sig std.Signature, simulate bool) (crypto.PubKey, sdk.Result)

ProcessPubKey verifies that the given account address matches that of the std.Signature. In addition, it will set the public key of the account if it has not been set.

func SetGasMeter 

func SetGasMeter(simulate bool, ctx sdk.Context, gasLimit int64) sdk.Context

SetGasMeter returns a new context with a gas meter set from a given context.

func ValidateMemo 

func ValidateMemo(tx std.Tx, params Params) sdk.Result

ValidateMemo validates the memo size.

func ValidateSigCount 

func ValidateSigCount(tx std.Tx, params Params) sdk.Result

ValidateSigCount validates that the transaction has a valid cumulative total amount of signatures.

Types

type AccountKeeper 

type AccountKeeper struct {
	// contains filtered or unexported fields
}

Concrete implementation of AccountKeeper.

func NewAccountKeeper 

func NewAccountKeeper(
	key store.StoreKey, proto func() std.Account,
) AccountKeeper

NewAccountKeeper returns a new AccountKeeper that uses go-amino to (binary) encode and decode concrete std.Accounts.

func (AccountKeeper) GetAccount 

func (ak AccountKeeper) GetAccount(ctx sdk.Context, addr crypto.Address) std.Account

GetAccount implements AccountKeeper.

func (AccountKeeper) GetAllAccounts 

func (ak AccountKeeper) GetAllAccounts(ctx sdk.Context) []std.Account

GetAllAccounts returns all accounts in the AccountKeeper.

func (AccountKeeper) GetNextAccountNumber 

func (ak AccountKeeper) GetNextAccountNumber(ctx sdk.Context) uint64

GetNextAccountNumber Returns and increments the global account number counter

func (AccountKeeper) GetPubKey 

func (ak AccountKeeper) GetPubKey(ctx sdk.Context, addr crypto.Address) (crypto.PubKey, error)

GetPubKey Returns the PubKey of the account at address

func (AccountKeeper) GetSequence 

func (ak AccountKeeper) GetSequence(ctx sdk.Context, addr crypto.Address) (uint64, error)

GetSequence Returns the Sequence of the account at address

func (AccountKeeper) IterateAccounts 

func (ak AccountKeeper) IterateAccounts(ctx sdk.Context, process func(std.Account) (stop bool))

IterateAccounts implements AccountKeeper.

func (AccountKeeper) Logger 

func (ak AccountKeeper) Logger(ctx sdk.Context) *slog.Logger

Logger returns a module-specific logger.

func (AccountKeeper) NewAccountWithAddress 

func (ak AccountKeeper) NewAccountWithAddress(ctx sdk.Context, addr crypto.Address) std.Account

NewAccountWithAddress implements AccountKeeper.

func (AccountKeeper) RemoveAccount 

func (ak AccountKeeper) RemoveAccount(ctx sdk.Context, acc std.Account)

RemoveAccount removes an account for the account mapper store. NOTE: this will cause supply invariant violation if called

func (AccountKeeper) SetAccount 

func (ak AccountKeeper) SetAccount(ctx sdk.Context, acc std.Account)

SetAccount implements AccountKeeper.

type AccountKeeperI 

type AccountKeeperI interface {
	NewAccountWithAddress(ctx sdk.Context, addr crypto.Address) std.Account

	IterateAccounts(ctx sdk.Context, process func(std.Account) bool)
}

AccountKeeper manages access to accounts.

type AnteOptions 

type AnteOptions struct {
	// If verifyGenesisSignatures is false, does not check signatures when Height==0.
	// This is useful for development, and maybe production chains.
	// Always check your settings and inspect genesis transactions.
	VerifyGenesisSignatures bool
}

type AuthParamsContextKey 

type AuthParamsContextKey struct{}

type BankKeeperI 

type BankKeeperI interface {
	SendCoins(ctx sdk.Context, fromAddr crypto.Address, toAddr crypto.Address, amt std.Coins) error
