Ark Invest and 21Shares enhance Bitcoin ETF transparency with Chainlink integration
Summary
Ark Invest and 21Shares have integrated Chainlink Proof of Reserve on the Ethereum mainnet to enhance transparency of the ARK 21Shares Bitcoin ETF (ARKB). This allows investors to verify that the ETF’s Bitcoin holdings fully support its value. The mechanism uses off-chain reserves data from Coinbase and Chainlink oracles for on-chain reporting. This move follows Bitwise's transparency initiative, and experts have praised it as setting a new standard. Since the US SEC approved several Bitcoin ETFs for trading in January, these investment vehicles have seen significant adoption and positive performance. ARKB holds over 33,000 units of Bitcoin, valued at around $2 billion, making it one of the top performers among launched spot Bitcoin ETFs.
