ArbLens
Tracks balances, P&L and open arb legs across 21+ exchanges and 9 chains in one dashboard.
ArbLens connects read-only API keys — no trading or withdrawal permissions — to 21+ crypto exchanges and 9 on-chain networks, syncing balances every 15 seconds so you can see which venue has free capital to fund the next trade. It auto-pairs long and short legs opened on different exchanges into one arb position, tracking spread, funding and net P&L per pair, and flags a leg as unhedged the moment its counterpart closes. Accounts that fail to sync are dimmed and marked stale rather than silently showing an old balance.
What holds up
- +Read-only, KMS-encrypted keys — no trading or withdrawal permissions requested
- +Stale or failed syncs are flagged, not silently shown as an up-to-date balance
- +Auto-pairs arb legs across venues and flags unhedged exposure the moment one leg closes
- +Separates free capital from locked-in-orders and margin so the total balance doesn't mislead you
Mind the limits
- −Only 21 exchanges and 9 chains covered — anything else needs to be requested first
- −No pricing shown on the page before you connect an account
