Building for the future 🔥

Arbitrum everywhere

[A.J. Warner @ajwarner90]

The @arbitrum protocol has probably foregone $3 million in fees this weekend due to the upgraded pricing algorithm despite having record traffic bursts.

Hard to lose out on that revenue but very confident that this is the right move long term. We need to continue building for the long term and allow our builders to have the bandwidth they need to profitably scale their apps.

We are building for 100x the demand of today and we need to keep that focus and mindset.

Arbitrum Everywhere.

[Ben Greenberg @hummusonrails]

Most hackathon projects never ship. Not because the builders aren't good, but because the format is wrong.
