# Drift Burn

{% hint style="info" %}
Once you have a [Drift N](/project-information/thorfi-nfts/types-of-nfts/drift-nfts.md)[FT](/project-information/thorfi-nfts/types-of-nfts/drift-nfts.md),  a Drift burn is how you accumulate [ThorFi Keycards](/project-information/thorfi-keycards.md), moving you one step closer to [ThorFi Capsules](/project-information/thorfi-capsules.md). 
{% endhint %}

A Drift burn results in your NFT becoming either a Drift burn Odin, or Thor [Keycard](/project-information/thorfi-keycards.md) NFT, dependent on the NFT type you burn. 

A Drift burn occurs in one of two ways;

1. Choosing to burn the Drift NFT before the end of its 90-day lifecycle
2. Linear Decay - occurring after 90 days
