Navigate to the Wagerr Block Explorer and connect your wallet.
You will need to sign transactions to approve the contract to spend coins in your wallet.
Create a bet slip by clicking on the odds of the event you wish to bet on.
Please note that Cross-chain betting includes fees of the chain in which you are betting in. The bet slip will automatically calculate those fees in WGR for you. The fee is a fixed amount and therefore for larger bets this fee becomes trivial.
Once the bet is placed, it will process and metamask (or whatever wallet you are using) will ask you to confirm the transaction.
You will also be able to see the WGR bet replicated on the Wagerr block explorer using the WGR Transaction ID.
