mineracks Spark testbed spark.mineracks.com signet experimental
An independent Spark Entity on Bitcoin signet: three signing operators with a 2-of-3 FROST threshold, running the upstream open-source operator unmodified. Point the Spark SDK at it and test deposits, transfers and unilateral exits without touching mainnet or anyone's production entity.
What this is, and is not
| Is | A complete Spark Entity you do not control, on a chain with no value, so you can exercise the trust model end to end: threshold signing, key tweaking on transfer, timelocked unilateral exit. |
| Is not | Part of the production Spark Entity (Lightspark and Flashnet run that) and not a mainnet service. There is no Spark Service Provider here, so Lightning send/receive, cooperative exit and swaps are unavailable. |
| Chain data | Our own signet node and explorer: https://signet.mineracks.com/api is the electrsUrl to use. |
