# Milestones and releases

> How crowdfunding milestones release funds on Boundless, and how each release amount is calculated.

Campaign milestones define what the creator will deliver, and funds are released from escrow one milestone at a time. This reduces risk for backers and keeps creators accountable.

## How it works

1. **Creator defines milestones** When [creating a campaign](/backers/create-a-campaign), the creator breaks the work into milestones (e.g., "Alpha release," "Documentation," "Mainnet launch").
2. **Backers fund the campaign** Contributions go into escrow. See [Back a project](/backers/back-a-project).
3. **Creator delivers** For each milestone, the creator submits evidence (e.g., a link, demo, or report).
4. **Reviewer approves** A [delegated reviewer](/backers/vote-on-campaigns) checks the evidence and approves the milestone.
5. **Release** The creator claims the milestone and that share of the funds is released.

## How each release is calculated

Crowdfunding uses **dynamic** release amounts. Each time a milestone is claimed, the amount released is the **funds remaining in escrow divided by the milestones remaining**. The last milestone takes whatever is left, so nothing is stranded.

For example, with 4,200 USDC raised across 3 milestones, the first claim releases 4,200 ÷ 3 = 1,400 USDC.

## For creators

* Define clear, verifiable milestones so backers and validators can approve releases without ambiguity.
* Deliver on time to maintain trust and unlock funds.

## For backers

* Review the milestone structure before backing so you know when and how funds are released.
