- This endpoint also is an asynchronous endpoint, which means the initial call does not return the response immediately. Please refer to the Async Endpoint doc for more information about how to use these APIs.
Field | Type | Description |
---|---|---|
burningAddress | string | The ETH address that owns the token to be burned. |
signature | string | Signature that proves that the owning address signed the relevant information to burn the token.
More info on how to generate the signature below. |
Using your Ethereum account’s private key, you are signing that you are trying to burn your token of
tokenId
. You can only do this if you own the token in question.const burnTypes = {
Burn: [
{ name: "tokenId", type: "uint256" },
],
};
// The data to sign
const value = {
tokenId: tokenId, // mandatory
};
// Domain info (if you're using the sandbox environment)
const domainInfo = {
name: 'Kudos',
// Mumbai
chainId: 80001,
verifyingContract: "0xB876baF8F69cD35fb96A17a599b070FBdD18A6a1"
};
// Domain info (if you're using the production environment)
const domainInfo = {
name: 'Kudos',
// Polygon - comment this out if you're on Mumbai
chainId: 137,
verifyingContract: "0x60576A64851C5B42e8c57E3E4A5cF3CF4eEb2ED6"
};
// Get signer
const provider = new ethers.providers.JsonRpcProvider(/* constructor params */);
const signer = provider.getSigner(/* address */);
// Obtain signatures
const burnSignature: string = await adminSigner._signTypedData(domainInfo, burnTypes, value);
