Type declaration

quoteSwap()
quoteSwap: (options: AccountQuoteSwapOptions) => Promise<AccountQuoteSwapResult>;

options
AccountQuoteSwapOptions Configuration options for creating the swap quote.
Returns
Promise<AccountQuoteSwapResult> A promise that resolves to the swap quote or a response indicating that liquidity is unavailable.
Example
const swapQuote = await account.quoteSwap({
  network: "base",
  fromToken: "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2", // WETH
  toToken: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC
  fromAmount: BigInt("1000000000000000000"), // 1 WETH in wei
});

if (swapQuote.liquidityAvailable) {

}
sendTransaction()
sendTransaction: (options: Omit<SendTransactionOptions, "address">) => Promise<TransactionResult>;
