Final Class Bridges a CrossmintEvmWallet into the checkout payer contract.
This adapter is intentionally EVM-only. The embedded checkout sends raw serialized EVM transactions, and the runtime wallet forwards those through the wallet transaction APIs using the same raw-transaction shape as the JS wallet SDK.

​
Constructors

​
CrossmintEvmWalletCheckoutPayer

Creates an EVM payer backed by wallet.

​
Properties

​
supportedChains

EVM chains the wallet can sign transactions on. Computed from the supportedChains argument (defaulting to [wallet.chain]) and normalized to drop duplicates and blanks.

​
address

EVM address of the backing CrossmintEvmWallet.

​
walletProviderKey

Always null — this adapter wraps an SDK-owned CrossmintEvmWallet rather than a third-party wallet provider, so there is no provider key to report.

​
initialChain

Chain currently selected for outgoing transactions. Starts at the initialChain constructor argument (defaulting to wallet.chain) and updates when the hosted checkout calls switchChain.

​
Methods

​
signAndSendTransaction

Signs and broadcasts a raw serialized EVM transaction received from the hosted checkout via the backing CrossmintEvmWallet. Returns CrossmintCheckoutTransactionSuccess with the transaction id on success. Errors are caught and surfaced as CrossmintCheckoutTransactionFailure — this method never throws so the hosted checkout can render a user-facing message.

​
switchChain

Switches the selected chain used for subsequent transactions. Throws ArgumentError when chain is not in supportedChains. Called by the hosted checkout when the user changes chain in the UI.

​
signMessage

Signs an arbitrary message with the backing EVM wallet’s approval signer. Returns the hex-encoded signature.
