There’s been a ton of chatter about wrapped tokens like Wrapped Bitcoin (WBTC) and Wrapped Ethereum (WETH) this week—a few of it respectable, a few of it top-tier shitposting.
Earlier this week, a number of notable crypto Twitter accounts started peddling the concept WETH was on the snapping point.
“ATTENTION: WETH is about to be bancrupt,” tweeted crypto influencer Cygaar. “I’ll begrudgingly bail out anybody holding WETH at a price of 0.5 ETH per WETH so as to save this house. You possibly can thank me as soon as the disaster has been averted.”
“We’d see a financial institution run on redeeming WETH quickly,” tweeted Gnosis co-founder Martin Köppelmann.
None of this was true.
Not like the bank-run tweets that swirled round Twitter amid the FTX collapse, WETH doesn’t have the identical counterparty danger. There isn’t any centralized group custodying the underlying Ethereum. There are not any over-leveraged funds within the Bahamas taking an enormous danger with consumer funds.
As an alternative, the important thing danger right here is wise contract danger.
To mint WETH, customers deposit Ethereum into a wise contract fairly than giving it to an alternate or a crypto lender to carry on to it. The explanation individuals use WETH as a substitute of ETH (in spite of everything, they’re principally the identical factor, proper?) is that it, not like Ethereum, can also be an ERC-20 token. This makes it a lot simpler to combine into numerous decentralized functions.
Thus, there was by no means a danger of insolvency or a financial institution run on this asset. It’s merely one other instance of the fairly obnoxious humorousness that exists within the trade. Positive, the sensible contract may by some means break down, but it surely has existed and operated easily for therefore lengthy that one thing like that will’ve already occurred by now if there was some type of bug.
WBTC, nevertheless, is way completely different.
“BitGo is the custodian for the BTC backing for wBTC,” wrote Rugdoc.io, a community-driven undertaking that opinions sensible contracts. “Bitgo froze FTX belongings, making a 4k surplus of BTC and the wBTC depeg. It is not your Bitcoin for those who maintain wBTC.”
This asset principally enables you to create an Ethereum-compatible model of Bitcoin in order that it may be utilized in completely different DeFi functions. Much more merely, it’s an ERC-20 token pegged to the worth of Bitcoin.
It’s additionally backed by actual Bitcoin, which, as talked about above, is custodied by a agency known as BitGo. For each 1 WBTC in circulation, BitGo has 1 actual Bitcoin.
At any time when a consumer needs to “unwrap” their WBTC and redeem it for the true deal, they have to undergo a service provider (this could possibly be an alternate, for instance). Doing this implies destroying (or burning) that WBTC and withdrawing one of many Bitcoin from custody.
Critically, it’s also possible to see this minting and burning exercise occurring on-chain due to a handy dashboard.
Final week WBTC depegged in worth from the underlying Bitcoin, which—given its design—was truly a bit extra worrisome (and never essentially a mean-spirited Twitter joke).
Usually, when a reduction like this emerges, market makers will swoop in and arbitrage the distinction for revenue by shopping for the cheaper WBTC and redeeming it for the true Bitcoin.
And that’s just about what they’ve been doing right here, too. However as a result of Alameda (the sister buying and selling agency to the collapse FTX) was an enormous WBTC consumer, their absence left plenty of arbitrage to do.
Thus, the market is doing a little bit of catch-up in addition to battling some severe FUD alongside the best way.
Proper now, WBTC is buying and selling at roughly a $15 low cost to the true deal. That’s peanuts. And it’s probably made some market makers all of the richer alongside the best way.
