You can fund Sorare with Trust Wallet via WalletConnect, which allows you to use a decentralized application (dapp) from a mobile wallet. It works on both mobile and desktop and is becoming one of the main standards for accessing an Ethereum dapp. Through WalletConnect, you will be able to connect your Trust Wallet to Sorare. Once your Trust Wallet is funded with ETH, connect your wallet in Sorare and transfer the funds from your wallet to Sorare.
Trust Wallet has some fundamental differences with MetaMask - e.g. Trust Wallet is available only on mobile, and MetaMask is available for mobile and browser. Sorare recommends MetaMask.
