# Transactions

There are 4 types of transactions in DEMOS.

1. Native
2. Crosschain
3. Web2
4. DemosWork

Using the demos sdk, you can create, sign and broadcast transactions as discussed in following chapters.

<Tip>
  Want one call per transaction instead of the build → sign → confirm → broadcast steps? See [Programmatic Transactions (`demos.run`)](/sdk/websdk/transactions/programmatic-transactions) — an additive `demos.run.*` facade with an automatic fee ceiling. The step-by-step API below stays fully supported.
</Tip>

<Info>
  Before sending native transactions, read [Amounts & Denominations](/sdk/websdk/transactions/denominations) to understand how DEM and OS amounts are passed (`bigint` is preferred), how the SDK detects the active wire format via `getNetworkInfo`, and the `SubDemPrecisionError` guard for sub-DEM amounts on pre-fork nodes.
