Coinbase Wallet supports assets on Ethereum, Solana, Base, Polygon, Avalanche, Bitcoin, and other blockchain networks. A Coinbase Wallet integration that limits the merchant to accepting payments on only one chain excludes customers whose assets sit on other networks within the same wallet. 27 Blockchain configures the integration to route transactions across all supported chains so the merchant's checkout is not restricted to a single network.
The multi-chain routing is handled within 27 Blockchain's payment infrastructure layer. The checkout detects which network the customer's Coinbase Wallet is connected to and processes the transaction on that chain. The merchant receives consolidated settlement reporting across all supported networks, so multi-chain complexity does not create additional reconciliation work.
