About
Arx HaLo chips are mini hardware signers -- and they're embedded in every ETHGlobal wristband! Using libHaLo you can generate transactions, EIP-191 and EIP-712 signatures easily. You can generate signatures direct from a browser via a tap. That means that you can do things like (1) use the chip as a wallet, (2) generate attestations (3) use the chip to generate entropy. ERS (the "Ethereum Reality Service" ) is a protocol that resolves chips to content. See docs below on how to enroll chips (find someone from Arx Research if you would like a chip that is not enrolled as all ETHGlobal wristbands direct to ETHGlobal content).Prizes

Build the most interesting and creative digi-physical experience. How can a signature tap from a wristband/card/tag spice up Ethereum? Onboard new users? Radically change how things work IRL? What's a L2 that should use chips?
Find us if you need more chips for testing!
Qualification Requirements
You may or may not use ERS for this prize, however, we expect that you will implement libHaLo. At a minimum you should use a signature obtained from a chip (on or offchain!)
