### Summary
Canton has no flash-liquidity present. Vacuumlabs will deliver a primitive for flash-liquidation, a reference flash liquidation integration, a settlement compatibility kit (that will tell if a particular asset can be flash-borrowed). This will allow for users to not have to hold idle liquidity for arbitrage trading, liquidation bots where transactions can be settled atomically.

Summary
A production-grade flash liquidity primitive for Canton, which would allow for borrow with no collateral, put the funds to work, and repay principal plus fee, all in one atomic transaction submitted by the borrower alone. If repayment falls short, the whole transaction is rejected and the pool is untouched. It runs on Canton Token Standard V2 (CIP-0112) settlement rails.
If this is something you’d be open to championing, or if you can point us to someone who might be a good fit, we’d really appreciate it.
Happy to answer any questions.
Thank you.
