Как работают токены WBTC?
В некоторых кошельках WBTC можно "обернуть" (и "развернуть"), например на CoinList.
Каковы преимущества "обёрнутых" токенов?
Самое главное: они дают владельцам цифровых активов свободу исследовать другие блокчейны.
Почему бы не просто пользоваться Ethereum?
Объем BTC, который был преобразован в обернутые токены, также растет. По данным DeFi Pulse, общая стоимость WBTC выросла на 943% с середины мая до середины августа 2020 года.
Как купить WBTC?
Процесс чеканки WBTC также относительно прост.

What is a DEX?
A decentralized exchange (DEX) is a type of exchange that specializes in peer-to-peer transactions of cryptocurrencies and digital assets. Unlike centralized exchanges (CEXs), DEXs do not require a trusted third party, or intermediary, to facilitate the exchange of cryptoassets.

Bridging Bitcoin (BTC) onto Polygon (Matic Network) via WBTC
Bitcoin (BTC) is a productive capital asset that can be used for yield farming opportunities on many blockchains.
If you have Bitcoin on the Bitcoin network, here’s your chance to participate in DeFi yield farming opportunities on Polygon.
One way to do it is to bridge native Bitcoin (BTC) into Wrapped Bitcoin (WBTC):
What is WBTC?
WBTC is the first ERC20 token backed 1:1 with Bitcoin. It brings greater liquidity to the Ethereum ecosystem including decentralized exchanges (DEXs) and financial applications.
WBTC standardizes Bitcoin to the ERC20 format, creating smart contracts for Bitcoin. This makes iteasier to write smart contracts that integrate Bitcoin transfers.
Trade BTC for WBTC on Binance
Deposit your BTC to Binance.
Then look for the WBTC/BTC trading pair.
Buy WBTC using BTC and then withdraw it as an ERC-20 token on the Ethereum network to an external wallet.
Once you have it in your Ethereum address, head over to Zapper — we will use the Zapper Bridge to bridge them over from Ethereum to Polygon.
Zapper Bridge
Approve the WBTC for spending by clicking on the Approve button.
Wait for WBTC to be approved by the Ethereum blockchain — this will take several minutes depending on network congestion and the amount of gas you paid.
Once it is approved, click on Confirm.
The modal will now update to bridge WBTC onto Polygon.
Give it several more minutes (between 10 to 15 minutes) for the bridge to now transfer the WBTC into your Polygon address.
Once you’ve successfully bridged the assets, you can find them in your wallet on Polygon.
Once your WBTC assets are on Polygon, you can use them across DeFi on Polygon such as lending them on Aave or provide liquidity on Sushiswap.
