Infrastructure a desk can rely on
Performance
A Rust execution core with live order books streamed from every venue, running next to your own venue connections.
Safety
Non-custodial by design. Execution runs on your servers, and your keys and funds never leave your venue accounts.
Reliability
Books resync on every gap, and orders and fills are reconciled against venue snapshots, so the blotter matches the venue.
Familiarity
Watchlists, depth, a ticket and a blotter laid out like the desks you already trade on, built for event contracts.
Trust
An open-source, MIT-licensed SDK. Read every line of code that touches your orders, and talk to the engineers who wrote it.
Simplicity
One order model for every venue, with access through the terminal, the Python SDK, REST or WebSocket.
One API for every venue.
Everything in the terminal is in the open-source SDK: the same client and order model on every venue.
pip install synpath
