Colossus
Colossus
Colossus is a stablecoin credit card network built as an Ethereum Layer 2, designed to settle transactions on-chain by reusing existing infrastructure (acquirers, EMV standards, POS terminals). The EMV terminal signs an Ethereum ERC-4337 transaction and, when its own rails are unavailable, the card falls back to legacy networks. The project — founded in 2025 by Joseph Delong (former CTO of SushiSwap) — aims to operate without traditional KYC/AML requirements based on its interpretation of the GENIUS Act, an approach still to be validated from a regulatory standpoint.

FAQ
Can an individual use Colossus?
Not yet in any meaningful way: it is an early-stage network/infrastructure aimed at issuers and acquirers rather than a mature end-consumer product.
Is Colossus regulated?
No established licenses are on record: the project states it operates without traditional KYC/AML requirements based on its interpretation of the GENIUS Act, which carries regulatory risk.
