Stop panicking about Wrapped Bitcoin — There are other coins

If fear is contagious, then Wrapped Bitcoin’s ( wBTC ) custodian, BitGo, has started a pandemic.

In August, BitGo’s planned Bitcoin ( BTC ) custody overhaul sparked panic among wBTC holders. Now, similar fears are enveloping other Bitcoin wrappers. 

They are overblown. Your wBTC is still secure, and safer alternatives are proliferating. Among newly launched Bitcoin wrappers — tokens representing BTC on other blockchains — Coinbase Wrapped BTC (cbBTC) is the best bet. 

Flying too close to (Justin) Sun

On Aug. 9, BitGo tipped plans to grant partial control of wBTC’s Bitcoin backing to BiT Global, a Hong Kong crypto exchange. The partnership wasn’t well received . 

BiT Global has ties to Justin Sun, the controversial founder of the Tron smart contract platform. He’s been the subject of multiple misconduct allegations, including November fraud charges from United States regulators. Sun also reportedly tried to misappropriate customer funds from Poloniex, a crypto exchange he bought in 2021. 

Decentralized finance (DeFi) protocols have scrambled to cut wBTC exposure. On Sept. 19, Sky — previously Maker — voted to completely remove wBTC from its lending platform . 

Now, the contagion is spreading. In September, rumors circulated alleging Coinbase was issuing unbacked Bitcoin IOUs to BlackRock, a crypto exchange-traded fund (ETF) sponsor. That triggered yet another bout of wrapper worries, this time over the safety of Coinbase’s cbBTC.

Overblown anxieties 

The Coinbase rumors are unfounded — and thoroughly debunked — but the concerns about BitGo’s BiT Global partnership are valid. They still don’t justify abandoning wBTC. 

Sun clearly has BiT Global under his thumb. He may even own a controlling interest in the company, according to reports . However, Sun doesn’t manage the crypto exchange, and he won’t be directly administering wBTC. Even if he did, misappropriating wBTC’s Bitcoin backing would be virtually impossible. 

BitGo stores wBTC’s Bitcoin in a multisignature wallet, which requires at least two authorized “signers” to approve every BTC transfer. Only one of those signers will be BiT Global. The other two signatures will stay with BitGo’s United States and Singapore affiliates, respectively.

BitGo publishes the addresses of every wBTC custodial wallet. As of Sept. 30, wBTC is backed 1:1 by approximately $10 billion worth of Bitcoin. 

The panic is finally subsiding. In September, BitGo pledged to notify wBTC holders 60 days in advance of any custody changes, including adding BiT Global as a signer. 

On Sept. 17, Sky halted plans to ditch wBTC after Block Analitica, a risk consultancy, said BitGo’s “additional details and clarity put us in a more comfortable position with the current state of WBTC operations and key management.”

On Sept. 26, wBTC’s total value locked (TVL) on Aave, a DeFi lending protocol, hit record highs of $2 billion, according to Dune Analytics .

Wrapper wars

The biggest threat to wBTC isn’t Sun — it’s competition from Coinbase’s upstart Bitcoin wrapper, cbBTC. 

Launched on Sept. 12, Coinbase’s cbBTC has already topped $250 million in TVL. Initially mintable on Ethereum and Base — Coinbase’s popular layer-2 scaling network — cbBTC will soon launch on Solana, according to a Sept. 20 post on X.

For anyone concerned about safe Bitcoin custody, Coinbase’s cbBTC is a clear winner. Its reserves are held by Coinbase Custody Trust, a New York chartered digital currency custodian . That means cbBTC is subject to the most stringent regulatory oversight in crypto. 

Stored in dedicated cold-storage wallets, cbBTC’s Bitcoin reserves are segregated from the exchange’s other assets and regularly audited by New York’s Department of Financial Services (NYDFS). They are even insured against cybersecurity risks. 

In fact, cbBTC explicitly commits to reimbursing holders for any Bitcoin reserves lost to exploits. It will be adding onchain proof-of-reserves soon . 

Coinbase’s cbBTC isn’t wBTC’s only challenger. In May, 21.co, the parent company of asset manager 21Shares, launched 21.co Wrapped Bitcoin (21BTC).

On Sept. 23, 21BTC added Chainlink proof-of-reserves , Web3’s gold standard for onchain reporting. That’s a good sign, but 21BTC still lacks cbBTC’s investor protections and oversight. 

Meanwhile, Threshold aims to establish tBTC as a decentralized alternative to custodial Bitcoin wrappers. The DeFi protocol — born from a merger of Keep and NuCypher — delegates tBTC mint-and-burn operations to a distributed network of validators. They are secured by Threshold’s native token, T.

It’s a work in progress. As of Sept. 30, tBTC is secured by 136 active nodes and some $84 million in staked collateral . At approximately $250 million, tBTC’s market capitalization is already high for Threshold’s modest economic security. 

Decentralized Bitcoin wrappers — including those on Bitcoin’s emerging layer-2 networks — might eventually dominate. For now, conventional investor protections are indispensable. That’s where Coinbase’s cbBTC shines. 

But, even after the BiT Global setback, it’s still wBTC’s race to lose.
