  We document an ongoing research process towards the implementation and
integration of a digital artefact, executing the lifecycle of a leveraged trade
with permissionless blockchain technology. By employing core functions of the
'Dai Stablecoin system' deployed on the Ethereum blockchain, we produce the
equivalent exposure of a leveraged position while deterministically automating
the monitoring and liquidation processes. We demonstrate the implementation and
early integration of the artefact into a hardened exchange environment through
a microservice utilizing standardized API calls. The early results presented in
this paper were produced in collaboration with a team of stakeholders at a
hosting organization, a multi-national online brokerage and cryptocurrency
exchange. We utilize the design science research methodology (DSR) guiding the
design, development, and evaluation of the artefact. Our findings indicate
that, while it is feasible to implement the lifecycle of a leveraged trade on
the blockchain, the integration of the artefact into a traditional exchange
environment involves multiple compromises and drawback. Generalizing the
tentative findings presented in this paper, we introduce three propositions on
the implementation, integration, and implications of executing key business
processes with permissionless blockchain technologies. By conducting
computational design science research, we contribute to the information systems
discourse on the applied utility of permissionless blockchain technologies in
finance and beyond.
