Lesson 5 - Burn Tokens

The FT4 session object provides a method to burn tokens. The burn method is used to burn 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;
}

In the code snippet above, the burn method is called on the session object's account property to burn the specified amount of tokens.
