What “signer” means
A signer is the definitive entity that ratifies contracts, authorizes funds, or cryptographically validates execution. It is an indispensable, high-trust term spanning legal agreements, multi-sig crypto custody, and automated governance.
The SI-era angle
As autonomous systems negotiate deals, they require verified approval to execute agreements and send funds. Super intelligence needs clear human and machine governance. This domain marks the trusted boundary where authority approves action.

Why .si
In September 2026 the US government officially renamed AI “Super Intelligence — SI”. Elon Musk (“No more AI. SI.”) and Nvidia’s Jensen Huang adopted it within days, and .si registrations jumped 2,199%. .si is the only address on the internet that spells SI — and every great word exists only once.
