Functions

func ApplyFuncIfNoError

func ApplyFuncIfNoError(ctx sdk.Context, f func(ctx sdk.Context) error) (err error)

This function lets you run the function f, but if theres an error or panic drop the state machine change and log the error. If there is no error, proceeds as normal (but with some slowdown due to SDK store weirdness) Try to avoid usage of iterators in f.

If its an out of gas panic, this function will also panic like in normal tx execution flow. This is still safe for beginblock / endblock code though, as they do not have out of gas panics.

func CanCreateModuleAccountAtAddr

func CanCreateModuleAccountAtAddr(ctx sdk.Context, ak AccountKeeper, addr sdk.AccAddress) error

CanCreateModuleAccountAtAddr tells us if we can safely make a module account at a given address. By collision resistance of the address (given API safe construction), the only way for an account to be already be at this address is if its claimed by the same pre-image from the correct module, or some SDK command breaks assumptions and creates an account at designated address. This function checks if there is an account at that address, and runs some safety checks to be extra-sure its not a user account (e.g. non-zero sequence, pubkey, of fore-seen account types). If there is no account, or if we believe its not a user-spendable account, we allow module account creation at the address. else, we do not.

func ContainsString

func ContainsString(s []string, e string) bool

check string array inclusion

func ConvertAddressToStrideAddress

func ConvertAddressToStrideAddress(address string) string

Convert any bech32 to stride address

func CreateModuleAccount

func CreateModuleAccount(ctx sdk.Context, ak AccountKeeper, addr sdk.AccAddress) error

CreateModuleAccount creates a module account at the provided address. It overrides an account if it exists at that address, with a non-zero sequence number & pubkey Contract: addr is derived from `address.Module(ModuleName, key)`

func FilterDepositRecords

func FilterDepositRecords(arr []recordstypes.DepositRecord, condition func(recordstypes.DepositRecord) bool) (ret []recordstypes.DepositRecord)

func GetFromBech32

func GetFromBech32(bech32str, prefix string) ([]byte, error)

GetFromBech32 decodes a bytestring from a Bech32 encoded string.

func GetVestedCoinsAt

func GetVestedCoinsAt(vAt int64, vStart int64, vLength int64, vCoins sdk.Coins) sdk.Coins

Compute coin amount for specific period using linear vesting calculation algorithm.

func HostZoneDenomFromStAssetDenom

func HostZoneDenomFromStAssetDenom(stAssetDenom string) string

Returns the native denom from an stDenom by removing the st prefix

func Int32MapKeys

func Int32MapKeys[V any](m map[int32]V) []int32

func Int64ToCoinString

func Int64ToCoinString(amount int64, denom string) string

func IsIBCToken

func IsIBCToken(denom string) bool

isIBCToken checks if the token came from the IBC module Each IBC token starts with an ibc/ denom, the check is rather simple

func IsOutOfGasError

func IsOutOfGasError(err any) (bool, string)

Frustratingly, this has to return the error descriptor, not an actual error itself because the SDK errors here are not actually errors. (They don't implement error interface)

func LogHeader

func LogHeader(s string, a ...any) string

Returns a log header string with a dash padding on either side Ex:

------------------------------ string ------------------------------

func LogICACallbackStatusWithHostZone

func LogICACallbackStatusWithHostZone(chainId string, callbackId string, status icacallbacktypes.AckResponseStatus, packet channeltypes.Packet) string

Returns a log string with a chain Id and icacallback as a prefix, and status of the callback Ex:

| COSMOSHUB-4   |  DELEGATE ICACALLBACK  |  ICA SUCCESS, Packet: ...

func LogICACallbackWithHostZone

func LogICACallbackWithHostZone(chainId string, callbackId string, s string, a ...any) string

Returns a log string with a chain Id and icacallback as a prefix Ex:

| COSMOSHUB-4   |  DELEGATE ICACALLBACK  |  string

func LogICQCallbackWithHostZone

func LogICQCallbackWithHostZone(chainId string, callbackId string, s string, a ...any) string

Returns a log string with a chain Id and icqcallback as a prefix Ex:

| COSMOSHUB-4   |  WITHDRAWALBALANCE ICQCALLBACK  |  string

func LogModuleMigration

func LogModuleMigration(ctx sdk.Context, versionMap module.VersionMap, moduleName string)

Logs a module's migration info

func LogWithHostZone

func LogWithHostZone(chainId string, s string, a ...any) string

Returns a log string with a chainId and tab as the prefix Ex:

| COSMOSHUB-4   |   string

func Max64

func Max64(i, j int64) int64

============================== AIRDROP UTILS ================================ max64 returns the maximum of its inputs.

func Min

func Min(a int, b int) int

func Min64

func Min64(i, j int64) int64

Min64 returns the minimum of its inputs.

func PrintPanicRecoveryError

func PrintPanicRecoveryError(ctx sdk.Context, recoveryError interface{})

PrintPanicRecoveryError error logs the recoveryError, along with the stacktrace, if it can be parsed. If not emits them to stdout.

func StAssetDenomFromHostZoneDenom

func StAssetDenomFromHostZoneDenom(hostZoneDenom string) string

Returns the stDenom from a native denom by appending a st prefix

func StringMapKeys

func StringMapKeys[V any](m map[string]V) []string

func ValidateAdminAddress

func ValidateAdminAddress(address string) error

func VerifyAddressFormat

func VerifyAddressFormat(bz []byte) error

VerifyAddressFormat verifies that the provided bytes form a valid address according to the default address rules or a custom address verifier set by GetConfig().SetAddressVerifier(). TODO make an issue to get rid of global Config ref: https://github.com/cosmos/cosmos-sdk/issues/9690

func VerifyTxHash

func VerifyTxHash(txHash string) (err error)

Verifies a tx hash is valid

Types

type AccAddress

type AccAddress []byte

AccAddress a wrapper around bytes meant to represent an account address. When marshaled to a string or JSON, it uses Bech32.

func AccAddressFromBech32

func AccAddressFromBech32(address string, bech32prefix string) (addr AccAddress, err error)

AccAddressFromBech32 creates an AccAddress from a Bech32 string.

type AccountKeeper

type AccountKeeper interface {
	NewAccount(sdk.Context, authtypes.AccountI) authtypes.AccountI
	GetAccount(ctx sdk.Context, addr sdk.AccAddress) authtypes.AccountI
	SetAccount(ctx sdk.Context, acc authtypes.AccountI)
}
