# `PdaSeedNode` (abstract)

The `PdaSeedNode` type helper represents all ways to define a PDA seed. Note that `PdaSeedNode` is a type alias and cannot be used directly as a node. Instead you may use one of the following nodes:

- [`ConstantPdaSeedNode`](./ConstantPdaSeedNode.md)
- [`VariablePdaSeedNode`](./VariablePdaSeedNode.md)
