Polkadot Relay Chain, parachains, and XCM transfers
Polkadot's parachain architecture means every parachain is its own chain settling to the Relay Chain. We track DOT staking, parachain auctions, and XCM cross-parachain flows in one workspace.
Polkadot's NPoS staking model uses nomination — DOT holders nominate validators rather than running their own. Rewards accrue per-era (~24 hours) and pay out automatically. Parachain auctions absorbed DOT through crowdloans (now legacy); the modern equivalent is coretime purchase. XCM is the inter-parachain messaging layer; transferring an asset from one parachain to another is a multi-step on-chain flow that needs reconciliation across all parachains involved. Asset Hub (formerly Statemint) is where native assets live without parachain logic.

Polkadot accounting questions
How does Wag3s handle XCM transfers between parachains?
As a multi-step intra-asset transfer with intermediate states surfaced. The asset is debited on the source parachain and credited on the destination; we follow the message and reconcile end-to-end.
Are DOT nomination rewards taxable on receipt?
Yes — the per-era reward distribution is the income event, valued at the DOT price on the era boundary.
