A new token backed one-to-one with bitcoin is now live on the ethereum blockchain.
“Wrapped BTC” (WBTC) officially launched its ERC-20 token Wednesday evening. The project was first unveiled in October as a joint initiative between decentralized exchange startups Kyber Network and Republic Protocol, as well as cryptocurrency custody company BitGo.
At the time, BitGo CTO Benedict Chan described WBTC as possessing both “the stability of bitcoin and the flexibility of ethereum,” likening the new crypto asset to traditional bank notes (the kind that were once redeemable for gold). While volatile compared to the U.S. dollar, bitcoin is the most liquid and stable of cryptocurrencies, he noted.
Now listed on cryptocurrency market data site CoinMarketCap, as of early Wednesday evening there was a reported 72.4214 WBTC on the ethereum network, slightly over-collateralized with 72.4216 BTC (roughly $250,000) locked in custody on the bitcoin blockchain.
Leveraging a technology known as “atomic swaps” to facilitate cross-chain cryptocurrency trades, users on ethereum can request WBTC from certified "merchants" after undergoing necessary anti-money-laundering and know-your-customer (AML/KYC) identification procedures.
Playing a key role in the exchange and liquidation of new WBTC tokens, merchants are defined in the technology's white paper as "the institution or party to which wrapped tokens will be minted to and burnt from."
According to the WBTC team, there are presently eight merchants to facilitate conversion between WBTC and BTC. These include: AirSwap, Dharma, ETHfinex, GOPAX, Kyber Network, Prycto, Ren and Set Protocol.
Traded on exchanges
In addition, a number of cryptocurrency exchanges have already procured part of the initial WBTC inventory and will be able to support its live supply directly on their respective platforms, according to a WBTC press release.
As well, several financially-focussed decentralized applications on ethereum, including bZx, Compound and dYdX, will allow “immediate usage” of the new token.
