Know exactly what you are signing with Pier Two's transaction analysis upgrade
Our Stake creation and transaction crafting endpoints have been extended in a backwards compatible way to include a pre-prepared transaction payload and associated simulation and analysis. This update reduces the steps required by developers integrating our API as well as offering increased security and transparency.
