Exit scam

Abacus was the largest Bitcoin-enabled Western darknet market of the mid-2020s before it collapsed in an apparent exit scam in July 2025.

History

Abacus launched in September 2021 under the name Alphabet Market and rebranded to Abacus in November 2021, at the time positioning itself as a successor to AlphaBay. It grew into the dominant Bitcoin-enabled Western venue, with analyses crediting it with the majority of Western Bitcoin-based darknet commerce in 2024 and estimated lifetime sales in the hundreds of millions of dollars.

Operation

The market accepted Bitcoin and Monero and used a central-deposit wallet model with multisig protection. It was Australian-facing but served international users, and its scale and brand recognition made it the default choice for Bitcoin-denominated buyers.

Downfall

In July 2025 the site went offline without warning and its operator accounts fell silent. Funds held in market wallets were not returned, and trackers classified the event as a probable exit scam. The collapse came weeks after law enforcement seized Archetyp, compounding the upheaval for Western users.

Legacy

Abacus's fall is widely seen as a turning point in the shift of Western darknet commerce away from Bitcoin and toward Monero-only venues, and its users redistributed across TorZon, DrugHub, Nexus and other survivors.
