Arbitrum Shake Shack Takeover at ETHDenver

Fiet has launched on Arbitrum, enabling institutions to make their existing capital programmable without moving it fully onchain. **How it works:** - Institutions prove reserves offchain (banks, custodians, exchanges) - Liquidity commits onchain only when needed - Capital stays in existing custody and treasury systems **Key benefits:** - Reserve-backed liquidity without idle capital - Onchain policy enforcement at execution - Lower-cost, scalable infrastructure This approach addresses a major friction point for institutional adoption by meeting capital where it already exists rather than requiring full migration.
