This contract allows creation and management of channels with configurable hooks, where each channel is an NFT

Implements channel management with the following security features:

Functions

constructor(address initialOwner) (public)

Constructor sets the contract owner and initializes ERC721

getChannel(uint256 channelId) → struct Channels.Channel (external)

Get a channel by its ID

_getChannelId(address creator, string name, string description, struct Metadata.MetadataEntry[] metadata) → uint256 (internal)

Calculates a unique hash for a channel

_channelExists(uint256 channelId) → bool (internal)

Internal function to check if a channel exists

_hashMetadataArray(struct Metadata.MetadataEntry[] metadata) → bytes32 (internal)

Internal function to hash metadata array for deterministic channel ID generation

createChannel(string name, string description, struct Metadata.MetadataEntry[] metadata, address hook) → uint256 channelId (external)

Creates a new channel

updateChannel(uint256 channelId, string name, string description, struct Metadata.MetadataEntryOp[] metadataOperations) (external)

Updates an existing channel's configuration

setHook(uint256 channelId, address hook) (external)

Sets the hook for a channel

_setHook(uint256 channelId, address hook) (internal)

Internal function to set the hook for a channel

channelExists(uint256 channelId) → bool (external)

Checks if a channel exists

setBaseURI(string baseURI_) (external)

Sets the base URI for NFT metadata

_baseURI() → string (internal)

Returns the base URI for token metadata

Internal function that overrides ERC721's _baseURI()

_createChannelMetadata(uint256 channelId, struct Metadata.MetadataEntry[] metadata) (internal)

Internal function to create channel metadata

_setChannelMetadata(uint256 channelId, struct Metadata.MetadataEntryOp[] operations) (internal)

Sets metadata for a channel

_deleteChannelMetadataKey(uint256 channelId, bytes32 keyToDelete) (internal)

Internal function to delete a specific channel metadata key

_channelMetadataKeyExists(uint256 channelId, bytes32 targetKey) → bool (internal)

Internal function to check if a channel metadata key exists

getChannelMetadata(uint256 channelId) → struct Metadata.MetadataEntry[] (public)

Get all metadata for a channel

getChannelMetadataValue(uint256 channelId, bytes32 key) → bytes (external)

Get metadata value for a specific key

getChannelMetadataKeys(uint256 channelId) → bytes32[] (external)

Get all metadata keys for a channel
