Bitrefill said a cyberattack on March 1, 2026 led to unauthorized hot-wallet transfers and disruption to parts of its internal infrastructure. The company reported that database logs indicate roughly 18,500 purchase records were accessed, with about 1,000 including encrypted customer names that it is treating as potentially exposed.

Peaster outlined a hypothetical onchain funding design for an independent zine called "Combinatoria," aimed at paying writers without relying on subscriptions or one-way donations. The concept adapts Bread Cooperative's vault approach: supporters deposit stablecoins that remain withdrawable while only the vault's yield is routed to a treasury, then streamed and split to writers using tools like Sablier and Splits. Peaster argues the framework's purpose is less about exact payouts and more about showing how existing primitives (vaults, streams, mints, multisigs) could support cultural projects that need financial sustainability.
