React

React to an NFT using a RARA reaction. This will generate an NFT (“Like Token”) for the Reactor. Add metadata to the reaction by including an IPFS hash.
Parameter Types
ReactionVault
Example
{
    transformId: Uint256, // The ID of the Reaction Transform you want to use
    quantity: Uint256, // The number of Reactions you'd like to send
    referrerAddress: Address, // The Address that should receive referrer cuts
    optionBits: Uint256, // Parameter version of the Reaction you're using
    takerNFTChainId: Uint256, // Chain ID of the NFT receiving the Reaction
    takerNFTAddress: Address, // Contract Address of the NFT receiving the Reaction
    takerNFTId: Uint256, // Token ID of the NFT receiving the Reaction
    curatorVaultOverride: Address, // Override used for alternate Curator Vaults
    ipfsMetadataHash: String // Additional metadata to be saved with Reaction
}

}
Send a Reaction with ethers.js and ipfs-http-client
See ReactionVault tab for contract definitions
​
[Optional] Save Reaction Metadata to IPFS
If you'd like to include a Comment or Tags with your Reaction, you'll need to save that information to IPFS first.  If you just want to send a Reaction you can skip this step.
import { client } from 'ipfs-http-client'
​
interface IReactionMetadata {
    comment?: String;
    tags?: String[];
}
​
// Instantiate a new IPFS Client -- we use an IPFS node hosted by theGraph
const client = create(new URL('https://api.thegraph.com/ipfs/api/v0/'));
​
// Create a metadata blob to store comments and/or tags.
const reactionMetadata: IReactionMetadata = {
    comment: "My first comment using the RARA! Social Curation Protocol",
    tags: ["rara", "social", "curation"]
}
​
// Save reaction metadata on IPFS to generate an ipfsCID.  Keep this ipfsCID handy as we'll use it in the next step.
const { ipfsCID } = await client.add(JSON.stringify(reactionMetadata));
​
Send a Reaction and Reaction Metadata to an NFT
To send a Reaction to an NFT, use the react function of the ReactionVault.  All parameters are required (see the Parameters section for more details).
import { Contract, constants } from 'ethers'
​
// Select an NFT to receive the reaction
const TakerNFT = {
    chainId: 80001,
    contractAddress: 0x2953399124f0cbb46d2cbacd8a89cf0599974963,
    tokenId: 107136376226630408484522358727913128313617592685310283300071728450490266025985
}
​
// Instantiate a Reaction Vault contract and attach a signer 
const ReactionVault = new Contract(
    reactionVault.address, 
    reactionVault.abi,
    signer
);
​
// Call the React function with required parameters 
const transaction = await ReactionVault.react(
    102265098525112739997130475423667270810501597805004267158805479941320194430532, //transformId,
    1, //quantity
    constants.AddressZero, // referrerAddress
    constants.Zero, // optionBits
    TakerNFT.chainId, // takerNFT Chain ID
    TakerNFT.contractAddress, // takerNFT Contract Address
    TakerNFT.tokenId, // takerNFT ID
    constants.AddressZero, // curatorVaultOverride
    ipfsCID // "QmV3wpfESJdZTaY262rZMqGSmH8cV9ThDDxRaKDm1ZmoWs"
);
​
// await completion of React function call
const receipt = await transaction.wait()
Parameters
All parameters are required
transformId
The ID of the reaction to be used. Only registered reactions can be used.
quantity
The number of reactions to be sent. If value is sent, the reaction quantity must equal the value / reactionPrice
referrerAddress
The address of the referring party. If value is sent, the referrer will be rewarded with value * saleReferrerBasisPoints.  Use addressZero if no referrerAddress is set.
optionBits
This parameter can be used to create different versions of the reaction NFT. Use 0 if optionBits are not set.
takerNFTChainId
Chain ID of the NFT receiving reactions
takerNFTContractAddress
Contract Address of the NFT receiving reactions
takerNFTTokenId
Token ID of the NFT receiving reactions
curatorVaultOverride
This parameter allows for multiple Curator Vaults. Use addressZero if curatorVaultOverride is not set.
IPFSMetadataHash
This parameter can be used to embed additional data about the user interaction.  Use maxInt256 if ipfsMetadataHash is not set.
