Institutional crypto treasuries are entering a new phase. In the first wave, treasurers allocated to Bitcoin and Ethereum, focusing on long-term exposure and basic staking yields. But as on-chain infrastructure matures and liquid staking protocols like Lido and EigenLayer gain traction, a new strategy is emerging: yield stacking. By combining liquid staking tokens (LSTs), restaking mechanisms, and DeFi services, treasuries can now layer multiple sources of yield on top of the same principal, without giving up custody, transparency, or compliance controls. Treasuries that can generate 3–5% from vanilla savings and staking, can now see 6–10% using enterprise-grade tools and increasingly permissioned crypto vaults. This is Treasury 3.0: dynamic, composable, and built for capital efficiency.
