ERC1155NameAndSymbol
Interface for ERC1155 contracts that provide name() and symbol() functions. These functions may not be part of the official interface but are used by some contracts.
name
function name() external view returns (string)symbol
function symbol() external view returns (string)ERC1155Vault
This vault holds all ERC1155 tokens that users have deposited. It also manages the mapping between canonical tokens and their bridged tokens.
sendToken
function sendToken(struct BaseNFTVault.BridgeTransferOp opt) external payableTransfers ERC1155 tokens to this vault and sends a message to the destination chain so the user can receive the same (bridged) tokens by invoking the message call.
Parameters
| Name | Type | Description |
|---|---|---|
| opt | struct BaseNFTVault.BridgeTransferOp | Option for sending the ERC1155 token. |
receiveToken
function receiveToken(struct BaseNFTVault.CanonicalNFT ctoken, address from, address to, uint256[] tokenIds, uint256[] amounts) external payableThis function can only be called by the bridge contract while invoking a message call. See sendToken, which sets the data to invoke this function.
Parameters
| Name | Type | Description |
|---|---|---|
| ctoken | struct BaseNFTVault.CanonicalNFT | The canonical ERC1155 token which may or may not live on this chain. If not, a BridgedERC1155 contract will be deployed. |
| from | address | The source address. |
| to | address | The destination address. |
| tokenIds | uint256[] | The tokenIds to be sent. |
| amounts | uint256[] | The amounts to be sent. |
onMessageRecalled
function onMessageRecalled(struct IBridge.Message message) external payableReleases deposited ERC1155 token(s) back to the user on the source chain with a proof that the message processing on the destination Bridge has failed.
Parameters
| Name | Type | Description |
|---|---|---|
| message | struct IBridge.Message | The message that corresponds to the ERC1155 deposit on the source chain. |
onERC1155BatchReceived
function onERC1155BatchReceived(address, address, uint256[], uint256[], bytes) external pure returns (bytes4)onERC1155Received
function onERC1155Received(address, address, uint256, uint256, bytes) external pure returns (bytes4)supportsInterface
function supportsInterface(bytes4 interfaceId) public view virtual returns (bool)See {IERC165-supportsInterface}.
