the slot game i'm making

fourdown.orgcoming soon

ten cats. seven districts. one rift.

fourdown is my one-person slot studio, making games about cats who did not consent to any of this. Kitty Borkin' 4D is the first: every cat in the city is on a leash and you hold the other end. free spins, a 4D rift where a cat the size of a building comes through the glass, and i did all of it: the math, the art, the code and the music.

tech i'm interested in rn

ika

ika does 2PC-MPC signing: a dWallet's private key is never assembled anywhere. you hold one share, the network holds the other, and neither can sign alone. the signature that comes out looks exactly like a normal ECDSA or EdDSA one, so a single dWallet can sign for bitcoin, evm chains, solana, sui, and aptos. it runs on sui today and is launching on solana soon.

how i use it

chromatika is built on it end to end. every vault in the wallet is an ika dWallet on the sui base: DKG to create it, a presign pool so signing is fast, cross-chain signing, and share re-encryption to hand a dWallet to someone else.
