Crypto Garage unveiled a regulated yen-token settlement trial in Japan

Crypto Garage on January 21, 2019 disclosed a one-year Japanese regulatory-sandbox trial for SETTLENET, a platform designed to exchange a yen-backed token and a bitcoin-linked asset on Blockstream’s Liquid sidechain. The announcement put a narrowly controlled institutional settlement experiment—not a public stablecoin launch—inside Japan’s formal framework for testing new financial technology.

Japan’s Financial Services Agency record shows that the government authorization was granted on January 18, 2019, three days before Crypto Garage announced it. The approved plan called for three to five registered Japanese virtual-currency exchange operators to conduct real transactions through a dedicated platform. Access would be limited to participants given special software and credentials, transaction limits would apply, and platform use would be free during the trial.

What SETTLENET was meant to test

Crypto Garage said participating exchanges would be able to issue a Japanese-yen-pegged token, called JPY-Token, on Liquid and trade it against L-BTC, the representation of bitcoin used on that sidechain. The planned settlement method used atomic swaps: the two assets would be exchanged as one coordinated operation, reducing the risk that one party delivered while the other failed to perform.

The official plan described the objective more precisely. It was intended to test whether bitcoin and a token backed by fiat currency could be exchanged promptly between licensed exchanges, and whether sidechain and company transaction records could support reviews of security, participant controls, price-formation transparency and the possibility of a stable, fair inter-exchange market.

Those were test objectives, not verified outcomes. The January 21 materials did not report completed transaction volumes, named participating exchanges, a public redemption mechanism for JPY-Token, reserve attestations, fees, realized settlement times or evidence that counterparty risk had been eliminated in practice. The FSA document also specified that no special regulatory exemption applied to the experiment.

Why the regulatory perimeter mattered

The important development was the combination of blockchain settlement technology with explicit institutional boundaries. Japan’s sandbox record limited the test to three to five domestically registered exchange operators and a one-year period running from January 2019 to January 2020. That scope made the project materially different from an unrestricted token issuance to retail users.

The structure also exposed a central tradeoff. Liquid was presented as a faster, confidential inter-exchange settlement network, but it was operated by a federation rather than Bitcoin’s open network. SETTLENET added controlled access and monitoring functions for regulatory authorities. In practical terms, the trial was testing whether some properties associated with crypto settlement—programmable assets and coordinated delivery—could be combined with identifiable operators, permissions and oversight.

That was institutionally relevant in early 2019 because exchanges still had to bridge fiat balances and crypto assets across separate operational systems. A delivery-versus-payment design could, if it worked as proposed, reduce principal risk between trading counterparties. The contemporaneous records establish the design and authorized testing conditions; they do not establish commercial adoption, systemic liquidity improvements or legal approval for a broader product.

The companies behind the trial

Crypto Garage was described as a financial-technology joint venture involving Digital Garage and Tokyo Tanshi. On January 21, Blockstream separately said it had taken an equity stake in Crypto Garage, would provide technical expertise, and had received an additional $10 million strategic investment from Digital Garage. Blockstream framed SETTLENET as the first application of the expanded relationship.

That funding figure came from Blockstream’s own announcement and was not independently detailed in the Japanese sandbox record. It should therefore be read as an attributable company disclosure, not as a regulator-verified amount.

What remained open on January 21

The trial’s evidentiary threshold was still ahead of it. The January 21 record supported authorization, design, duration and participant limits, but not performance. The next questions were which licensed exchanges joined, how yen backing and redemption would work, what transaction caps were imposed, whether atomic settlement operated reliably at meaningful volume, and what conclusions regulators drew after the test. Until those answers existed, SETTLENET was best understood as a bounded proof of concept rather than a functioning new layer of Japan’s crypto market infrastructure.
