Electrum compatibility

CategoryCompatibilityStatusReviewed / Observed partialLast reviewed2026-09-12

Summary

MoreBC2 has current dated read-only Electrum observations for BitcoinII infrastructure.

Successful Electrum protocol calls establish server reachability and limited protocol behavior. They do not prove compatibility with Electrum wallet software or other third-party wallets.

Canonical evidence:

• Public infrastructure smoke test — 2026-09-11
• API Electrum page
• Infrastructure service directory

Current tested endpoints

Endpoint	2026-09-11 result
tcp://infra1.bitcoin-ii.org:50008	Connected; server.version returned ElectrumX 1.18.0, protocol 1.4.
ssl://infra1.bitcoin-ii.org:50009	Connected over TLS 1.3; hostname certificate validation succeeded; server.version returned ElectrumX 1.18.0, protocol 1.4.
tcp://explorer.bitcoin-ii.org:5008	Timed out.

The TLS certificate observed for infra1.bitcoin-ii.org was valid for that hostname and reported an expiry date of 2026-11-20 in the client environment.

Historical protocol observations

The earlier July smoke test exercised additional read-only methods including:

• server.version
• server.features
• blockchain.headers.subscribe

That record observed protocol maximum 1.4.3 and the BitcoinII genesis hash:

0000000028f062b221c1a8a5cf0244b1627315f7aa5b775b931cfec46dc17ceb

Those July details remain historical evidence. The September recheck establishes current endpoint reachability and server identity, not a complete repeat of every July method.

Compatibility boundaries

Current evidence does not establish:

• Electrum wallet software compatibility;
• address/scripthash history correctness across wallet workflows;
• fee-estimate behavior in wallets;
• transaction construction or signing behavior;
• transaction broadcast through Electrum;
• long-running subscriptions;
• reconnect/load behavior;
• hardware-wallet integration;
• replay-protection-aware signing by third-party wallet stacks.

The older explorer.bitcoin-ii.org:5008 candidate should not be presented as a working current endpoint because it timed out again in the September check.

Safe wording

BitcoinII currently has a reachable ElectrumX service at infra1.bitcoin-ii.org over TCP and TLS, with current read-only protocol reachability observed on 2026-09-11. Third-party Electrum-wallet compatibility remains unverified.

Verification

Status: Reviewed / Observed partial
Primary sources checked: 2026-09-11 public-infrastructure smoke test plus preserved July Electrum record
Notes: Current evidence establishes read-only server reachability only; wallet and broadcast compatibility remain outside the tested scope.
