“Shib Owes You” (abbreviated as SOU) is a compensation mechanism launched by the Shiba Inu ecosystem at the end of 2025 to address losses from a previous hack on the Plasma Bridge. It carries a vibe of “IOU + blockchain + meme culture”—serious (because it's actually repaying money) yet infused with self-deprecating humor and community memes (“SHIB owes you, and we're keeping track”).
