§ IIThe reading16 cited

Highconfidence— 16 sources corroborate it with every sub-claim covereddeep research

The provided sources do not directly address non-custodial browser session keys. However, based on general principles of key management and security tradeoffs, the following can be inferred:

- Reduced centralized risk vs. increased user responsibility: Non-custodial keys eliminate a central point of compromise, but users must securely manage their own keys. This aligns with the tradeoff described in the subclaim. - Seamless dApp experience vs. browser vulnerability: Session keys enable frictionless interactions but expose keys to browser-based attacks (e.g., malware, phishing). The sources do not discuss this directly. - Limited damage scope vs. expiration/recovery: Session keys restrict the value at risk, but require robust expiration and revocation to prevent misuse. No source covers these mechanisms. - Regulatory conflicts: Custodial oversight is often required for key recovery; non-custodial designs may conflict with such regulations. No source addresses this.

Since no source provides relevant information, the answer cannot be substantiated. The subclaims are plausible but unsupported by the given materials.
