nodeError(desc: "transaction underpriced")

I make the transaction from json:

    data = 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;

Hello？

[mloit]

A number of changes have been made around Transactions since this was posted. Unfortunately the fromJSON functions were prematurely removed from the API along the way. (Though I've now restored them in #558)

Can you try testing now using #558 as your base, to see if the issue has been resolved? Barring any issues, the PR should be merged in early next week with the next 2.x release.

If you use SPM you can repoint it to use the PR temporarily for testing:
.package(url: "https://github.com/skywinder/web3swift.git", branch: "pull/558/head")
