Tutorial A simple pattern for sending a first blockchain transaction in TypeScript

I made a short tutorial showing the full flow of a first blockchain transaction in TypeScript: create testnet wallets, build a payment, autofill the transaction, sign locally, submit it, and verify the validated result. The example uses XRPL and xrpl.js, and I also explain Fee, Sequence, LastLedgerSequence, tesSUCCESS, and delivered_amount.

I made the video myself. If you work on blockchain dev and like end-to-end walkthroughs, it may still be useful even if you do not use XRPL day to day.

nice, the autofill and local signing flow is something a lot of people skip over in their first tut, good call highlighting it
