First, please note that when you choose the wBTC (Polygon) withdrawal method, your rewards will be sent on the Polygon network, NOT the Ethereum network. Sending crypto on the incorrect network will result in the permanent loss of funds.
Ethereum-wBTC wallets are common on most centralized exchanges, but Polygon-wBTC wallets are common on most Web 3 Wallets. For clarity, we want to use a Polygon-wBTC wallet.
Here are some Web 3 wallet providers that offer a Polygon-wBTC address:
Coinbase Wallet* (different from just Coinbase)
Metamask*
Trust Wallet (POS wallet)
Binance Web3 Wallet (different from just Binance or Binance US)
OKX
Here are some centralized exchanges that do not offer a Polygon-wBTC address. Please DO NOT use these:
Coinbase
Binance & Binance US
Kraken
