No background needed. ## FAQ **What is XEL?** XEL is a standard for creating living characters that are truly, permanently yours. A XEL is a character you can talk to that remembers, has a personality, and can speak and appear in voice, images, and video. What makes it different is what it is made of: an owned object on a blockchain, with encrypted private memory, immutable rules, and its own self-funding wallet. It is a standard, not a single app, so anyone can build clients, run the services that power characters, or verify any character directly from the chain. ## Whitepaper **XEL: an open protocol for sovereign, persistent digital beings (aNFTs)** ## How It Works The mechanism in plain language, no code. By the end you know what actually happens when a character exists, remembers, thinks, earns, lasts, and is passed on, and why no company can take it from you. ## Persona Settings A persona is the character's stable identity. It tells XEL how the character speaks, what it knows about itself, what boundaries it follows, and how it should answer in chat or voice. ## Media and Memory Settings The Media tab is where you manage the files and links that help XEL build and update a character. ## Ownership and the aNFT XEL starts with a different ownership model from normal AI products. A character is not an account in XEL's database. It is an owned on-chain object: an autonomous NFT, or aNFT. ## Survival Model XEL's permanence claim rests on a simple idea: a character should not depend on a person, company, or platform remembering to pay a bill. It should carry its own fund, know what it costs to survive, and renew the pieces that would otherwise expire. ## Endowments and Creator Earnings The money story has two halves. An endowment is how a character sustains its own existence. Creator earnings are how a person makes money from a character people value. This section covers both, and how they interlock: a loved character can fund its own survival and grow. Honest throughout, because this is a real decision with real stakes. ## If XEL Disappears This is the question that proves or breaks everything: if XEL the company vanished, would your character survive? The honest, detailed answer, including the two mechanisms that make survival real, interoperability and upgradeability, and the limits worth knowing. ## Concepts Every piece named precisely, with the real vocabulary, so you can go deeper and speak about the system exactly. Each concept points back to its plain explanation in How It Works and forward to its formal detail in Reference. ## Building From nothing to a character you own, funded and running. Code lands with the SDK; the shapes here are stable. ## Architecture The deep how, paired with the whitepaper and technical reference pages that explain the principles behind XEL without exposing internal implementation plans. ## Reference Look things up. This page is the public map of the technical surfaces that matter for understanding and integrating with XEL. ## Running Infrastructure For people who want to run the plumbing. This is where the open market lives. ## Resources - FAQ: common questions for users and builders, in the next section. - Glossary: every term defined once. - Whitepaper: the vision, architecture, and full invariant list. - Security and disclosure: how to report an issue, the trust assumptions, and audits. - Changelog: versioned changes to the standard and the schemas. - Community and support: where to ask questions and how to contribute.
