Programmable Transaction Blocks

Programmable transaction blocks (PTBs) let you compose multiple commands into a single atomic transaction on Sui. Commands can transfer objects, call Move functions, split and merge coins, and more, with results from one command flowing into the next.

What is a PTB?

Programmable transaction blocks are a group of commands that complete a transaction on Sui.
