Functions ¶
func ParseError ¶
ParseError parses raw contract errors into human-readable error messages for ERC20 operations.
Types ¶
type BaseERC20Signature ¶
type BaseERC20Signature string
BaseERC20Signature represents function signatures for basic ERC20 token operations
const ( // Name represents the name function signature Name BaseERC20Signature = "name()" // Symbol represents the symbol function signature Symbol BaseERC20Signature = "symbol()" // Decimals represents the decimals function signature Decimals BaseERC20Signature = "decimals()" // BalanceOf represents the balanceOf function signature BalanceOf BaseERC20Signature = "balanceOf(address)" // TotalSupply represents the totalSupply function signature TotalSupply BaseERC20Signature = "totalSupply()" // TokenURI represents the tokenURI function signature TokenURI BaseERC20Signature = "tokenURI(uint256)" // #nosec G101 // Approve represents the approve function signature Approve BaseERC20Signature = "approve(address,uint256)" // TransferFrom represents the transferFrom function signature TransferFrom BaseERC20Signature = "transferFrom(address,address,uint256)" // SafeTransferFrom represents the safeTransferFrom function signature SafeTransferFrom BaseERC20Signature = "safeTransferFrom(address,address,uint256)" )
func (BaseERC20Signature) GetHex ¶
func (s BaseERC20Signature) GetHex() string
GetHex returns the hex representation of the function signature
func (BaseERC20Signature) GetSelector ¶
func (s BaseERC20Signature) GetSelector() []byte
GetSelector returns the hex representation of the function signature
func (BaseERC20Signature) String ¶
func (s BaseERC20Signature) String() string
type Interactions ¶
type Interactions struct {
*base.Interactions
// contains filtered or unexported fields
}
Interactions provides methods for interacting with ERC20 token contracts.
func NewIERC20Interactions ¶
func NewIERC20Interactions( baseInteractions *base.Interactions, address common.Address, signatures []BaseERC20Signature, transactOps ...*bind.TransactOpts, ) (*Interactions, error)
NewIERC20Interactions creates a new instance of IERC20AInteractions from a base interaction interface and an NFT contract address.
func (*Interactions) Allowance ¶
Allowance returns the amount of tokens that spender is allowed to spend on behalf of owner
func (*Interactions) Approve ¶
func (d *Interactions) Approve(to common.Address, allowance *big.Int) (*types.Transaction, error)
Approve approves an address to transfer a specific token.
func (*Interactions) Decimals ¶
func (d *Interactions) Decimals() (uint8, error)
Decimals returns the number of decimals used to get its user representation.
func (*Interactions) GetAddress ¶
func (d *Interactions) GetAddress() common.Address
GetAddress returns the ERC20 contract address.
func (*Interactions) GetBalance ¶
func (d *Interactions) GetBalance() (*big.Int, error)
GetBalance retrieves the balance of NFTs for the associated address.
func (*Interactions) GetSession ¶
func (d *Interactions) GetSession() transaction.Session
GetSession returns the current session used for NFT interactions.
func (Interactions) Instance ¶
func (s Interactions) Instance() *bind.BoundContract
func (*Interactions) Name ¶
func (d *Interactions) Name() (string, error)
Name returns the name of the NFT.
func (*Interactions) Symbol ¶
func (d *Interactions) Symbol() (string, error)
Symbol returns the symbol of the NFT.
func (*Interactions) TokenMetaInfos ¶
func (d *Interactions) TokenMetaInfos() (*models.TokenMeta, error)
TokenMetaInfos retrieves metadata about the specified token such as name, symbol, and URI.
func (*Interactions) TotalSupply ¶
func (d *Interactions) TotalSupply() (*big.Int, error)
TotalSupply returns the total number of NFTs minted.
func (*Interactions) TransferTo ¶
func (d *Interactions) TransferTo(to common.Address, amount *big.Int) (*types.Transaction, error)
TransferTo transfers a specific token to another address after verifying ownership.
