wBTC Chain introduces a native cryptocurrency - wBTC Chain Coin ($BTCN). This community-focused token serves as the primary governance token for the wBTC blockchain and comes with different use cases. Users will have two options for paying transaction fees on wBTC Chain - $BTCN and $wBTC. During the wBTC launch phase, users typically use $wBTC for this purpose. Once the blockchain is stable, $BTCN will become the "token" to drive transactions, smart contracts, and dApps.
