Functions

func CondResetSignature

func CondResetSignature(publicKey *ecdsa.PublicKey, userOps []*model.UserOperation, hashes []common.Hash) error

CondResetSignature resets the signature of UserOperations if the signature is invalid.

func GenXHash

func GenXHash(opHashes []common.Hash) common.Hash

GenXHash computes the hash of multiple UserOperations' hashes. It concatenates the hashes, sorts them, and hashes the result. The result is the xChainHash.

func GenerateSignature

func GenerateSignature(messageHash common.Hash, privateKey *ecdsa.PrivateKey) ([]byte, error)

GenerateSignature signs the prefixed message hash with the private key.

func HasEVMSolution

func HasEVMSolution(op *model.UserOperation) bool

HasEVMSolution checks if the provided bytes likely represent valid EVM calldata through a number of heuristics.

func HasXDataInCallData

func HasXDataInCallData(op *model.UserOperation) bool

func HasXDataInSignature

func HasXDataInSignature(op *model.UserOperation) bool

func IsAggregate

func IsAggregate(op *model.UserOperation) bool

func RecoverSigner

func RecoverSigner(messageHash common.Hash, signature []byte) string

func SignUserOperations

func SignUserOperations(signer *signer.EOA, hashes []common.Hash, userOps []*model.UserOperation) error

SignUserOperations is a helper function to sign one or multiple UserOperations.

func VerifyHashSignature

func VerifyHashSignature(messageHash common.Hash, signature []byte, publicKey *ecdsa.PublicKey) bool

VerifyHashSignature verifies the signature against the message hash and public key.

func VerifySignature

func VerifySignature(publicKey *ecdsa.PublicKey, userOps []*model.UserOperation, hashes []common.Hash) (bool, error)

VerifySignature verifies the signature of one or multiple UserOperations. VerifySignature verifies the signature of one or multiple UserOperations.

Types

type ConsoleStyle

type ConsoleStyle struct {
	Color string
	Reset string
}

ConsoleStyle holds ANSI escape codes for console formatting

type DebugParseResult

type DebugParseResult struct {
	XDataInCallData  bool
	OpType           uint16
	IntentJSONLength int
	IntentJSON       []byte
	LeadingGarbage   []byte // Garbage bytes before IntentJSON
	TrailingGarbage  []byte // Garbage bytes after IntentJSON
	HashListLength   int
	HashList         []model.CrossChainHashListEntry
	Error            error
}

DebugParseResult contains the parsed cross-chain data along with debug information

func DebugParseCrossChainData

func DebugParseCrossChainData(data []byte, xDataInCallData bool) *DebugParseResult

DebugParseCrossChainData performs detailed parsing of cross-chain data with debugging information

func (*DebugParseResult) String

func (r *DebugParseResult) String() string

String implements the Stringer interface for pretty-printing debug results

type DebugParser

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

DebugParser provides methods for parsing and analyzing cross-chain data

func NewDebugParser

func NewDebugParser() *DebugParser

NewDebugParser creates a debug parser that can be used to analyze cross-chain data

func (*DebugParser) ParseAndDebug

func (p *DebugParser) ParseAndDebug(data []byte, xDataInCallData bool) (*model.CrossChainData, *DebugParseResult)

type State

type State int

State represents the state of a UserOperation

const (
	StateUnsigned State = iota
	StateConventional
	StateIntentUnsolved    // Intent JSON in callData, awaiting solution
	StateSolutionLess      // Intent with empty solution
	StateIntentSolved      // Intent with valid EVM solution
	StateXChainUnsolved    // XData in callData, awaiting solution
	StateXChainInSignature // XData appended to signature
	StateXChainSolved      // XData with valid EVM solution
	StateXChainAggregate   // Special case: Aggregate XChain operation
)

func DetermineState
