Guidelines for establishing context before an audit.
Perform a comprehensive on-chain security audit of a deployed MultiversX smart contract. Use when reviewing a contract's security posture, permissions, state, and economic safety without source code.
Read on-chain state in MultiversX smart contracts. Use when accessing caller info, account balances, block timestamps, ESDT token metadata, local roles, code metadata, or any data from self.blockchain().
Gas-optimized cache patterns for MultiversX smart contracts using Drop-based write-back caches. Use when building contracts that read/write multiple storage values per transaction, DeFi protocols, or any gas-sensitive contract.
Identify ambiguous requirements and ask targeted clarifying questions for MultiversX development. Use when user requests are vague, missing technical constraints, or have conflicting requirements.
Comprehensive code analysis toolkit for MultiversX smart contracts. Covers differential review (version comparison, upgrade safety), fix verification (validate patches, regression testing), and variant analysis (find similar bugs across codebase). Use when reviewing PRs, verifying security patches, or hunting for bug variants.

| description | Core data structures and types for MultiversX Go SDK. |
These types define the core objects interacting with the blockchain.
data.Transaction is the main struct for all network interactions.
type Transaction struct {
Nonce uint64 `json:"nonce"`
Value string `json:"value"`
RcvAddr string `json:"receiver"`
SndAddr string `json:"sender"`
GasPrice uint64 `json:"gasPrice,omitempty"`
GasLimit uint64 `json:"gasLimit,omitempty"`
Data []byte `json:"data,omitempty"`
Signature string `json:"signature,omitempty"`
ChainID string `json:"chainID"`
Version uint32 `json:"version"`
Options uint32 `json:"options,omitempty"`
Guardian string `json:"guardian,omitempty"`
GuardianSignature string `json:"guardianSignature,omitempty"`
Relayer string `json:"relayer,omitempty"`
RelayerSignature string `json:"relayerSignature,omitempty"`
}
type AddressWithType struct {
address []byte
hrp string // "erd" usually
}
// Methods
// NewAddressFromBech32String(bech32)
// NewAddressFromBytes(bytes)
// AddressAsBech32String()
type Account struct {
Address string `json:"address"`
Nonce uint64 `json:"nonce"`
Balance string `json:"balance"` // BigInt string
Username string `json:"username"`
CodeHash string `json:"codeHash"`
RootHash string `json:"rootHash"`
DeveloperReward string `json:"developerReward"`
}
type NetworkConfig struct {
ChainID string
MinGasLimit uint64
MinGasPrice uint64
GasPerDataByte uint64
GasPriceModifier float64
AdditionalGasForTxSize uint64
...
}
type VmValueRequest struct {
Address string `json:"scAddress"`
FuncName string `json:"funcName"`
CallValue string `json:"value"`
CallerAddr string `json:"caller"`
Args []string `json:"args"` // Hex encoded arguments
}
type VmValuesResponseData struct {
ReturnData []string `json:"returnData"` // Hex encoded return values
ReturnCode string `json:"returnCode"`
ReturnMessage string `json:"returnMessage"`
GasRemaining uint64 `json:"gasRemaining"`
GasRefund uint64 `json:"gasRefund"`
OutputAccounts map[string]*OutputAccount `json:"outputAccounts"`
}
Value as string: To prevent overflow (Go's int64 is too small for big token amounts).Data field is often hex-encoded when checking explorers, but SDK expects bytes/string.
