With the addition of BNB Chain (BNB) and Avalanche (AVAX), there are now four supported networks, including Ethereum (ETH) and Polygon (POLY) (MATIC). Coinbase's own in-app decentralized exchange (DEX) on four networks is available to wallet users who want to trade on-chain. Bridging with tokens is not yet possible. In contrast to CoinBase's centralized infrastructure, Coinbase Wallet allows customers to self-guard their bitcoin and gives them access to on-chain services. Currently, there are 173 tokens listed on Coinbase’s market. These figures pale in comparison to the thousands of Coinbase Wallet users now have access to across the four networks.
Sending tokens between networks without going via a centralized exchange is known as network bridging (CEX). Multichain and Wormhole are two popular token bridges. Coinbase is rolling out its Web3 wallet and browser for the mobile app, though only to a limited number of users at first. This will provide mobile traders with access to a diverse ecosystem of DEXes on supported networks, in addition to Coinbase's own.
