PoolTogether is multi-chain, meaning it lives across multiple blockchains. Before making a deposit in the PoolTogether protocol you need to decide which network you want to deposit on.
Currently, the PoolTogether protocol is live on:
If you want to deposit on Optimism, Avalanche or Polygon, you first have to add the network to your wallet. You can do this in the PoolTogether dApp, by choosing the Network in the top right corner.
PoolTogether allows you to deposit USDC in exchange for tickets (PTaUSDC) on the aforementioned networks.
Depositing, claiming prizes, and withdrawing requires a transaction and will cost a network fee.
To deposit, you need a small amount of the network's native gas token in your wallet to cover the transaction fees.
