Polkadot Parachain Crowdloans · interactive mechanism simulation

DOT holders lend into a parachain's crowdloan fund → contributions bid in a candle auction with a randomized retroactive close → the winning fund locks DOT for a lease → contributors earn reward tokens until refund at lease end. Edit the parameters and watch the auction clear.

Illustrative simulation. Defaults mirror the researched crowdloan mechanism (child-trie contribution accounting, retroactive candle-auction close, up to 96-week leases, off-protocol reward tokens), but contribution sizes, timing, and the "reward collapse" opportunity-cost shock are simplified for visualization — not live onchain data.
