Part 5: Burning tokens

You can burn tokens through the FT4 session object, which exposes a burn method that removes tokens from the account.

asset_management/src/hooks/token-hooks.ts

import { useFtSession } from "@chromia/react";import { publicClientConfig as clientConfig } from "@/utils/generate-client-config";interface BurnTokenParams {  ticker: string;  name: string;  amount: number;}function useBurnTokens() {  const { data: ftAccounts } = useFtAccounts({ clientConfig });  const { data: session } = useFtSession(    ftAccounts?.length ? { clientConfig, account: ftAccounts[0] } : null,  );  const burnTokens = useCallback(    async (token: BurnTokenParams) => {      if (!session) return;      try {        await session.account.burn(token.ticker, createAmount(token.amount));        onSuccess?.(token);      } catch (error) {        console.error(error);        onError?.(token);      }    },    [session],  );  return burnTokens;}

The snippet calls burn on the session's account property, passing the number of tokens to burn.
