About APR arbitrage

How do I read the APR spread?

The spread is how many percent higher APR trades on one exchange than on the other. We measure it at tradeable prices (ask/bid) net of fees; “net” is closer to what you actually keep.

Is this arbitrage worth taking?

Look past the spread: check volume, order-book depth and the deposit/withdrawal status on Kraken and Astar DEX. If deposits or withdrawals are shut, or the book is thin, the spread exists on paper but you cannot trade into it.
