🗳️ Cubik Speedrun Funding Round

In last week’s issue I shared the Solana Speedrun Game Jam, a 5-day gaming hackathon that produced some solid, playable games built on Solana.

Now Cubik is hosting a quadratically funded grants round for projects coming out of the Game Jam. Quadratic funding is a crowdfunding mechanism to ensure that smaller contributors have a greater impact.

So go check out the games, give them a play, and contribute to the ones you like, but hurry because this Cubik funding round only lasts for a few more days.

This episode is about compressed NFTs, but the first half is an absolute master class in finding Product Market Fit (PMF) from the founders of Tensor.

When Tensor launched, Magic Eden was the dominant Solana NFT marketplace by a wide margin. Tensor set itself apart by targeting “prosumer” NFT collectors and taking advantage of the up & coming NftFi space.

_ilmoi and 0xrwu discuss how Tensor is building the #1 NFT marketplace in Solana and why compressed NFTs are Solana's new unlock.

They cover why they chose Solana, the advantages of professional vs retail products, compressed NFTs, Tensor's roadmap, crypto's path to mass adoption and more!
