⚡ Ark signet · experimental

An experimental Ark server on Bitcoin signet, run as a non-commercial tech demonstration by mineracks. Ark is an off-chain scaling protocol where you hold VTXOs (virtual UTXOs) that move instantly and cheaply — while always keeping the right to exit unilaterally to the Bitcoin base layer. Point a compatible wallet at the server below and play with it.

⚠ Experimental tech demonstration — not a business. Please read.

This is a non-commercial, not-for-profit experiment on signet (test coins, no real value) — a hobbyist tech demonstration to explore Ark. It is not a service, product, or business, charges no fees, and comes with no warranty of any kind.
It runs at deliberately microscopic scale, may break, and may be reset or taken offline at any time without notice. Don't rely on it for anything.
Ark's safety model is that you can always exit your VTXOs unilaterally to the Bitcoin base layer without the operator's cooperation — but this is experimental software, so treat anything here as disposable.
By connecting you accept it is experimental and entirely at your own risk, and our terms of service.

Two implementations — play with either

Ark has two independent open-source server implementations. This demo lets you try them side by side.

arkd Live

Ark Labs / arkade-os — the implementation that powers the Arkade wallet ecosystem.

Server URL (signet)

https://ark.mineracks.com

Paste this as the Ark server / ASP URL in a compatible wallet, set the network to signet, and create a VTXO. Fund it from any signet faucet.

bark Coming soon

Second / second-tech — an independent Ark implementation with a different design lineage.

Server URL (signet)

coming soon

A second, independent Ark server is being stood up alongside arkd so you can compare the two streams of the protocol. Check back shortly.

Compatible wallets

Ark wallets that can point at a custom server URL on signet. Set the network to signet and enter the server URL above.

Arkade — web wallet (arkd)
Bordalix — mobile wallet (arkd)
bark CLI — Second's reference client (for the bark server, when live)

Wallet support for Ark is young and moving fast — exact connection steps vary by app. If a wallet asks for a network, choose signet.

What is Ark?

Ark lets many users share Bitcoin liquidity off-chain through a server (an Ark Service Provider). You receive VTXOs — virtual outputs that can be sent instantly and for negligible fees — and the server batches everyone's activity into periodic on-chain rounds. The key property: you can always unilaterally exit your VTXOs to the base layer if the server misbehaves or disappears, so it is not pure custody. It's a different point in the scaling design space from Lightning — no channels to manage, easier receiving, at the cost of periodic interactivity with the server.

About this server

Runs arkd v0.9.4 against our own Bitcoin Core (signet) full node — self-contained, no third-party backend.
