Design Principles

Tychi Wallet is engineered around a small set of non-negotiable principles that guide every architectural and product decision. These principles exist to ensure the wallet remains secure, scalable, an

1. Non-Custodial by Default

Tychi never holds or moves user assets without explicit user-signed authorization. Private keys remain local to the device.

2. Abstracted Complexity

Gas fragmentation, routing, multi-chain differences, and DApp interactions are abstracted behind predictable flows. The system must reduce cognitive load without reducing user control.

3. Modular Feature System

All advanced capabilities (gas abstraction, cold wallet mode, debit card, AI modules) operate as independent modules, so the wallet remains lightweight and maintainable.

4. Assistive Intelligence, Not Automation

AI modules (like PTI or fee insights) provide guidance and risk signals, but never execute, alter, or block user transactions.

5. Cross-Chain Uniformity

Regardless of chain (EVM, Solana, Sui, Tron), transaction review, signing, and confirmation follow a consistent interface to avoid user confusion and reduce error rates.

These principles define how Tychi behaves across the app, backend systems, chain integrations, and future modules.
