Class: HypercertClient
The HypercertClient
is a core class in the hypercerts SDK, providing a high-level interface to interact with the hypercerts system.
It encapsulates the logic for storage, evaluation, indexing, and wallet interactions, abstracting the complexity and providing a simple API for users. The client is read-only if no walletClient was found.
Example
const config: Partial<HypercertClientConfig> = {
chain: {id: 11155111 },
};
const client = new HypercertClient(config);
Param
The configuration options for the client.
Implements
Constructors
constructor
• new HypercertClient(config
): HypercertClient
Creates a new instance of the HypercertClient
class.
This constructor takes a config
parameter that is used to configure the client. The config
parameter should be a HypercertClientConfig
object. If the public client cannot be connected, it throws a ClientError
.
Parameters

readContract | <abi, functionName, args>(args : ReadContractParameters <abi , functionName , args >) => Promise <ReadContractReturnType <abi , functionName , args >> | Calls a read-only function on a contract, and returns the response. - Docs: https://viem.sh/docs/contract/readContract - Examples: https://stackblitz.com/github/wevm/viem/tree/main/examples/contracts/reading-contracts Remarks A "read-only" function (constant function) on a Solidity contract is denoted by a view or pure keyword. They can only read the state of the contract, and cannot make any changes to it. Since read-only methods do not change the state of the contract, they do not require any gas to be executed, and can be called by any user without the need to pay for gas. Internally, uses a Public Client to call the call action with ABI-encoded data .

waitForTransactionReceipt | (args : WaitForTransactionReceiptParameters <undefined | Chain >) => Promise <TransactionReceipt > | Waits for the Transaction to be included on a Block (one confirmation), and then returns the Transaction Receipt. If the Transaction reverts, then the action will throw an error. - Docs: https://viem.sh/docs/actions/public/waitForTransactionReceipt - Example: https://stackblitz.com/github/wevm/viem/tree/main/examples/transactions/sending-transactions - JSON-RPC Methods: - Polls eth_getTransactionReceipt on each block until it has been processed. - If a Transaction has been replaced: - Calls eth_getBlockByNumber and extracts the transactions - Checks if one of the Transactions is a replacement - If so, calls eth_getTransactionReceipt . Remarks The waitForTransactionReceipt action additionally supports Replacement detection (e.g. sped up Transactions). Transactions can be replaced when a user modifies their transaction in their wallet (to speed up or cancel). Transactions are replaced when they are sent from the same nonce. There are 3 types of Transaction Replacement reasons: - repriced : The gas price has been modified (e.g. different maxFeePerGas ) - cancelled : The Transaction has been cancelled (e.g. value === 0n ) - replaced : The Transaction has been replaced (e.g. different value or data ) Example ts import { createPublicClient, http } from 'viem' import { mainnet } from 'viem/chains' const client = createPublicClient({ chain: mainnet, transport: http(), }) const transactionReceipt = await client.waitForTransactionReceipt({ hash: '0x4ca7ee652d57678f26e887c149ab0735f41de37bcad58c9f6d3ed5824f15b74d', }) |

writeContract | <abi, functionName, args, TChainOverride>(args : WriteContractParameters <abi , functionName , args , undefined | Chain , undefined | Account , TChainOverride >) => Promise <`0x${string}`> | Executes a write function on a contract. - Docs: https://viem.sh/docs/contract/writeContract - Examples: https://stackblitz.com/github/wevm/viem/tree/main/examples/contracts/writing-to-contracts A "write" function on a Solidity contract modifies the state of the blockchain. These types of functions require gas to be executed, and hence a Transaction is needed to be broadcast in order to change the state. Internally, uses a Wallet Client to call the sendTransaction action with ABI-encoded data . Warning: The write internally sends a transaction – it does not validate if the contract write will succeed (the contract may throw an error). It is highly recommended to simulate the contract write with contract.simulate before you execute it. Example ts import { createWalletClient, custom, parseAbi } from 'viem' import { mainnet } from 'viem/chains' const client = createWalletClient({ chain: mainnet, transport: custom(window.ethereum), }) const hash = await client.writeContract({ address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2', abi: parseAbi(['function mint(uint32 tokenId) nonpayable']), functionName: 'mint', args: [69420], }) Example ts // With Validation import { createWalletClient, custom, parseAbi } from 'viem' import { mainnet } from 'viem/chains' const client = createWalletClient({ chain: mainnet, transport: custom(window.ethereum), }) const { request } = await client.simulateContract({ address: '0xFBA3912Ca04dd458c843e2EE08967fC04f3579c2', abi: parseAbi(['function mint(uint32 tokenId) nonpayable']), functionName: 'mint', args: [69420], } const hash = await client.writeContract(request) |

Methods
batchMintClaimFractionsFromAllowlists
▸ batchMintClaimFractionsFromAllowlists(claimIds
, units
, proofs
, roots?
, overrides?
): Promise
<undefined
| `0x${string}`>
Mints multiple claim fractions from allowlists in a batch.
This method first retrieves the wallet client and account using the getWallet
method. If the roots are provided, it verifies each proof using the verifyMerkleProofs
function. If any of the proofs are invalid, it throws an InvalidOrMissingError
.
It then simulates a contract call to the batchMintClaimsFromAllowlists
function with the provided parameters and the account, and submits the request using the submitRequest
method.
Parameters
Name | Type | Description |
---|---|---|
claimIds | bigint [] | The IDs of the claims to mint. |
units | bigint [] | The units of each claim to mint. |
proofs | (`0x${string}` | Uint8Array )[][] | The proofs for each claim. |
roots? | (`0x${string}` | Uint8Array )[] | The roots of each proof. If provided, they are used to verify the proofs. |
overrides? | SupportedOverrides | Optional overrides for the contract call. |
