Two more adapters under Settings › Names & Certificates:
Namecoin — .bit names resolve by calling name_show "d/<name>" on the
configured JSON-RPC endpoint and following `translate` or `alias` records
to a clearnet host. Pure IP records aren't followed yet (that needs
in-browser DNS override + TLS pinning, which comes later). Namecoin has
no free public RPC, so the toggle is off by default and the row carries a
"Needs an RPC URL" note instead of a "Not wired yet" one; set yours in
Advanced.
Handshake — non-ICANN hostnames resolve through the public hns.to web
gateway (user-overridable in Advanced). hns.to proxies the request to a
Handshake node and serves the on-chain content. A bundled list of common
ICANN TLDs (original gTLDs + popular new gTLDs + every ccTLD) keeps the
default collision policy ("icann-wins") from hijacking clearnet names.
Setting the policy to "hns-wins" removes that gate.
Both adapters follow the ENS adapter's shape — tryExtraResolvers in main.js
calls each in turn after the BNS lookup; the first one that returns a URL
loads it. Settings copy on both rows updated.

// Handshake resolver — routes non-ICANN TLDs through a public HNS web
|
|
// gateway (hns.to by default). hns.to receives `foo.<tld>.hns.to`, looks up
|
|
// the Handshake TLD, fetches the on-chain site, and serves it back. From
|
|
// Theseus's side the adapter is a one-liner URL rewrite + a collision check
|
|
// to decide whether to touch the hostname at all.
|
|
//
|
|
// The collision check matters: Handshake auctioned on-chain TLDs that
|
|
// collide with real DNS names (e.g. ".app", ".dev"). We don't want to
|
|
// hijack those by default. With collision_policy = "icann-wins" (default),
|
|
// the adapter returns null for any TLD in a bundled "common ICANN" list so
|
|
// clearnet takes over. With "hns-wins", we always try HNS first.
|
|
//
|
|
// The list isn't the full IANA root zone (~1600 entries). It's the few
|
|
// hundred TLDs real users actually see: original gTLDs, popular new gTLDs,
|
|
// every ccTLD. If a TLD escapes the list and happens to collide with an
|
|
// HNS registration, the user can switch to "icann-wins" and whitelist via
|
|
// per-host overrides (future). Nothing breaks silently — the collision is
|
|
// opt-in by the user turning HNS on.
