Function signFusionQuote

Signs a fusion quote by automatically selecting between permit and on-chain signing based on the payment token's capabilities. If the token supports ERC20Permit, it will use permit signing; otherwise, it will fall back to on-chain signing.

Example

const signedQuote = await signFusionQuote(meeClient, {
  fusionQuote: {
    quote: quotePayload,
    trigger: {
      tokenAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48", // USDC
      chainId: 1,
      amount: "1000000" // 1 USDC
    }
  },
  account: smartAccount // Optional
});

Throws

Will throw an error if:

The quote format is invalid
The signing process fails
The token information cannot be retrieved
