# Blockchains, Tokens & Wallets

## Blockchains & Tokens Supported

We are currently active on below set of EVM-compatible blockchains. There is fundamentally no difference in the Sportsbook operations across these chains i.e. same set of smart contracts, powering our operations, have been deployed.

Each chain has a respective token which can be used to place trades. e.g. if you have to wager on any market / event via the Polygon blockchain, then you need to have USDT in your wallet. You will also require the native currency of that blockchain to pay the gas fees.

## Wallets Supported

We believe in user control and privacy. To ensure a secure and decentralized experience, we allow you to use any **self-custodial wallet** to interact with our platform. A self-custodial wallet (also known as a non-custodial wallet) is a type of wallet where you control your private keys. This means you are the only one with access to your funds, unlike exchange or custodial wallets, where a third party holds your private keys. Hence, self-custodial wallets give you complete ownership and responsibility over your assets.

**Self-custodial wallets typically used by our users:**

* [MetaMask](https://metamask.io/)
* [Trust Wallet](https://trustwallet.com/)
* [Coinbase Wallet](https://www.coinbase.com/wallet)
* All wallets supporting [WalletConnect](https://www.coingecko.com/learn/what-is-walletconnect-how-to-use-walletconnect) protocol such as: [Rainbow](https://rainbow.me/en/), [Gnosis Safe](https://safe.global/), [Argent](https://www.argent.xyz/), [BitPay](https://www.bitpay.com/) etc.
* Hardware wallets such as: [Ledger](https://www.ledger.com/), [Trezor](https://trezor.io/), etc.
