According to @muneeb, Bitcoin will likely never add privacy at the base layer, so privacy features like stealth BTC addresses should be built on Layer-2s such as Stacks if the L2 is fully self-custodial (source: @muneeb on X, Nov 17, 2025). According to @muneeb, information can leak both when crossing a bridge and when moving funds from a public address to a stealth address, and he proposes a design with the public address on L1 and the stealth address on L2 (source: @muneeb on X, Nov 17, 2025). According to @muneeb, the hard technical requirement is a fully self-custodial L2 BTC model that guarantees users can always retrieve their BTC even if the L2 fails (source: @muneeb on X, Nov 17, 2025). According to @muneeb, he is actively working on this approach to enable stealth BTC addresses on an L2 like Stacks (source: @muneeb on X, Nov 17, 2025).
