DepositBoxERC721

depositERC721 depositERC721(string schainName, address erc721OnMainnet, uint256 tokenId) external

Allows msg.sender to send ERC721 token from mainnet to schain.

Requirements:

  • Receiver contract should be defined.

  • msg.sender should approve their token for DepositBoxERC721 address.

postMessage postMessage(bytes32 schainHash, address sender, bytes data) external

Allows MessageProxyForMainnet contract to execute transferring ERC721 token from schain to mainnet.

Requirements:

  • Schain from which the tokens came should not be killed.

  • Sender contract should be defined and schain name cannot be Mainnet.

  • DepositBoxERC721 contract should own token.

addERC721TokenByOwner addERC721TokenByOwner(string schainName, address erc721OnMainnet) external

Allows Schain owner to add an ERC721 token to DepositBoxERC721.

Emits an ERC721TokenAdded event.

Requirements:

  • Schain should not be killed.

  • Only owner of the schain able to run function.

getFunds getFunds(string schainName, address erc721OnMainnet, address receiver, uint256 tokenId) external

Allows Schain owner to return each user their tokens. The Schain owner decides which tokens to send to which address, since the contract on mainnet does not store information about which tokens belong to whom.

Requirements:

  • DepositBoxERC721 contract should own such token.

  • msg.sender should be an owner of schain

  • IMA transfers Mainnet <→ schain should be killed

gasPayer gasPayer(bytes32 schainHash, address sender, bytes data) → address external

Returns receiver of message.

Requirements:

  • Sender contract should be defined and schain name cannot be Mainnet.

getSchainToAllERC721Length getSchainToAllERC721Length(string schainName) → uint256 external

Should return length of a set of all mapped tokens which were added by Schain owner or added automatically after sending to schain if whitelist was turned off.

getSchainToAllERC721 getSchainToAllERC721(string schainName, uint256 from, uint256 to) → address[] tokensInRange external

Should return an array of range of tokens were added by Schain owner or added automatically after sending to schain if whitelist was turned off.

initialize initialize(contract IContractManager contractManagerOfSkaleManagerValue, contract ILinker linkerValue, contract IMessageProxyForMainnet messageProxyValue) public

Creates a new DepositBoxERC721 contract.

getSchainToERC721 getSchainToERC721(string schainName, address erc721OnMainnet) → bool public

Should return true if token was added by Schain owner or automatically added after sending to schain if whitelist was turned off.

_removeTransferredAmount _removeTransferredAmount(address erc721Token, uint256 tokenId) internal

Removes the ids of tokens that was transferred from schain.

_receiveERC721 _receiveERC721(string schainName, address erc721OnMainnet, address to, uint256 tokenId) → bytes data internal

Allows DepositBoxERC721 to receive ERC721 tokens.

Emits an ERC721TokenReady event.

Requirements:

  • Whitelist should be turned off for auto adding tokens to DepositBoxERC721.

_addERC721ForSchain _addERC721ForSchain(string schainName, address erc721OnMainnet) internal

Adds an ERC721 token to DepositBoxERC721.

Emits an ERC721TokenAdded event.

Requirements:

  • Given address should be contract.

_getTokenInfo _getTokenInfo(contract IERC721MetadataUpgradeable erc721) → struct Messages.Erc721TokenInfo internal

Returns info about ERC721 token such as token name, symbol.

ERC721TokenAdded ERC721TokenAdded(string schainName, address contractOnMainnet) event

Emitted when token is mapped in DepositBoxERC721.

ERC721TokenReady ERC721TokenReady(address contractOnMainnet, uint256 tokenId) event

Emitted when token is received by DepositBox and is ready to be cloned or transferred on SKALE chain.
