# Origin Burn

{% hint style="info" %}
An Origin Burn is your fastest way to accumulate [ThorFi Keycards](/project-information/thorfi-keycards.md), moving you one step closer to [ThorFi Capsules](/project-information/thorfi-capsules.md). 
{% endhint %}

An Origin Burn is an action able to be taken in the [Marketplace](/project-information/capsule-marketplace.md). This action takes your NFT and turns it directly into either an Odin Keycard NFT or a Thor Keycard NFT, dependent on the NFT type you burn.

Origin Burn keycards may then be paired up, (one Origin Burn Odin keycard, and one Origin Burn Thor keycard) go through [Fusion](/project-information/thorfi-nfts/nft-actions/fusion.md), and become Origin Burn [Capsules](/project-information/thorfi-capsules.md), which have the best perk pool available.
