Cryptocurrency exchange Kraken has launched its own tokenized version of Bitcoin representing BTC holdings stored by the company.
On Oct. 17, Kraken officially <a data-ct-non-breakable="null" href="https://blog.kraken.com/news/kbtc" rel="null" target="null" text="null" title="null">introduced</a> Kraken Wrapped Bitcoin (kBTC), a token backed 1:1 by an equivalent amount of Bitcoin (<a data-ct-non-breakable="null" href="https://cointelegraph.com/bitcoin-price" rel="null" target="null" text="null" title="null">BTC</a>) held in Kraken’s custody.
The new ERC-20 token is interoperable with networks, including Ethereum and OP Mainnet (formerly Optimism), and can be used in decentralized applications (DApps), Kraken said.
“With kBTC, we’re bringing the power of Bitcoin to new networks, underpinned by the trust and security expertise Kraken has established over the last decade,” the exchange stated, adding:
<blockquote>
 “We believe kBTC reinforces Bitcoin’s position as the epicenter of crypto, empowers crypto builders to explore new ways to use Bitcoin, and pushes the entire ecosystem forward.”
</blockquote>

Kraken said the Bitcoin backing kBTC is held at Kraken Financial, a Wyoming-chartered special purpose depository institution. 
The firm added that the kBTC ERC-20 smart contract was audited by Trail of Bits, a security firm that has <a data-ct-non-breakable="null" href="https://cointelegraph.com/news/worldcoin-trail-of-bits-audit-no-vulnerability-orb-software" rel="" target="_self" text="null" title="https://cointelegraph.com/news/worldcoin-trail-of-bits-audit-no-vulnerability-orb-software">worked on major projects like Worldcoin</a>. 
“This audit, which kBTC passed, involved a detailed examination of our codebase and client architecture, aimed at identifying and addressing any potential security vulnerabilities,” Kraken stated.
One can verify kBTC’s onchain reserves by checking onchain data with links provided by Kraken, including links to the kBTC OP Mainnet smart contract, kBTC ETH smart contract and the BTC custody address.

<a data-ct-non-breakable="null" href="https://cointelegraph.com/learn/a-beginners-guide-to-understanding-wrapped-tokens-and-wrapped-bitcoin" rel="null" target="null" text="null" title="null">Wrapped crypto assets</a> like Wrapped Bitcoin (<a data-ct-non-breakable="null" href="https://cointelegraph.com/wrapped-bitcoin-price-index" rel="" target="_self" text="null" title="https://cointelegraph.com/wrapped-bitcoin-price-index">WBTC</a>) are tokens backed one-to-one by an underlying asset, usually native to another blockchain network or platform.
In wrapped tokens, the original asset is “wrapped” into a digital vault, while a newly minted token is created to transact on other platforms.
Wrapped tokens allow non-native assets to be used on any blockchain, enabling interoperability between networks.

For example, Bitcoin can be accessed on the Ethereum blockchain by using tokens such as WBTC, which might be useful to users of apps that <a data-ct-non-breakable="null" href="https://cointelegraph.com/news/how-to-store-bitcoin-on-metamask" rel="null" target="null" text="null" title="null">don’t support the original Bitcoin blockchain</a> like MetaMask wallet.
Launched in 2019, Ethereum-based WBTC was one of the first wrapped tokens introduced and is the second-largest wrapped cryptocurrency, with a market cap of nearly $10 billion, <a data-ct-non-breakable="null" href="https://www.coingecko.com/en/categories/wrapped-tokens" rel="nofollow noopener" target="_blank" text="null" title="https://www.coingecko.com/en/categories/wrapped-tokens">according</a> to CoinGecko.
