Hardware wallet · Last reviewed 2026-10-12

Widely used hardware wallet brand. Review recovery model and buy only via official channels.

Nostr client · MIT · Last reviewed 2026-10-12

Polished multi-platform Nostr client with caching. Still: back up your nsec offline.

Risk notes: Caching improves UX; it does not replace offline key backup or multi-relay hygiene.

Decentralized data · Last reviewed 2026-10-12

Primary project site for Autonomi network docs and clients. Field notes on our Autonomi pillar.

Risk notes: Source moved to the WithAutonomi GitHub org in May 2026; the old maidsafe/autonomi repo is archived — don't build from it.

Upstream project resources for Monero-class privacy tech. Research the protocol — we make no price calls.

Risk notes: Educational primary source for Monero-class privacy — not a trading venue. Always verify wallet downloads and signatures from getmonero.org paths.

Bitcoin education · AGPL-3.0 · Last reviewed 2026-10-12

Open-source Bitcoin explorer and mempool visualizer. We use public fee/hashrate APIs on /metrics.

Risk notes: Watch for telemetry / companion features that undo local residency. Verify installers.

Decentralized AI · MIT · Last reviewed 2026-10-12

Reference desktop (GUI) and command-line wallets from the Monero Project, with an option to run your own full node. Current release v0.18.5.3.

Risk notes: Download only from getmonero.org and verify hashes/GPG signatures before running. A remote node sees your IP and timing; running your own node keeps that local.
