SoulLayer's design logic breaks away from the traditional "tool-based AI" paradigm and proposes a new structure with individual evolution, auditable personality trajectory, and provable emotional interaction. Each AI Companion created by each user is based on the three-layer structure of "personality vector + on-chain memory index + state evolution log" to generate a Soul NFT with autonomous behavior deviation capabilities, behavior traceability, and ownership confirmation attributes.

The project is deployed based on a multi-chain architecture and is currently compatible with Ethereum, Polygon, Solana, and Avalanche networks. In the future, it will be expanded to be compatible with Layer 2 Rollup and decentralized AI computing protocols (such as DePIN networks). Its smart contract system includes: personality casting contracts, memory storage contracts, behavior evolution contracts, personality fusion contracts, and comprehensive control modules for market transactions and governance proposals.

SoulLayer's biggest technological breakthrough is that: **All changes in partners do not rely on centralized model records or implicit databases, but form a verifiable individual trajectory on the chain through structured "behavior snapshots + emotional mapping + state fork paths". **This makes each Soul NFT a real and traceable "emotional evolution certificate" rather than a static image or short conversation model.

In terms of openness, SoulLayer provides a complete developer access standard, allowing personality template creators, semantic behavior model designers, memory configuration collaborators and governance participants to jointly promote SoulLayer's personality ecology. The platform plans to launch the Soul Fusion module in the future, allowing two different partners to perform "personality fusion" and "trait inheritance" on the chain, and explore personality property co-creation models and on-chain personality experimental applications.

Currently, SoulLayer is still in the ecological governance stage after the mainnet protocol is deployed, and the application interface and partner creation process are being prepared. The team said that they will give priority to promoting the stability, security and openness of the protocol layer to ensure that the system structure has complete logical transparency and trust boundaries before individual behavior is assetized.
