Side by side measurements
Cheapest perp venue to hold a position, live funding normalized
Trading| Provider | Funding cost to hold a long 24h | Annualized (ETH) | Per-hour rate (ETH) | BTC hold 24h | SOL hold 24h |
|---|---|---|---|---|---|
| Aster | 0.71 bps | - | - | 0.85 bps | 2.09 bps |
| Polymarket | 0.43 bps | 10.6% | 0.12 bps | - | 0.89 bps |
Funding is signed. Positive means longs pay shorts, negative means longs get paid to hold. Venues settle on different native periods (1h for Hyperliquid and dYdX, 4h or 8h elsewhere); every figure is normalized from the venue's own quoted rate and interval before ranking. Funding is only the holding cost. Opening costs (taker fee, spread, impact) are the companion bench perp-fees.

Stability is not directionality. A venue with persistently positive but tight-banded funding ranks better here than one that flips between positive and negative every settlement, even if the second venue offers better average carry. Read alongside perp-funding for direction and average level.

How this pair was selected
Auto-generated pairs require: both providers in the same benchmark for seven consecutive days, at least 1000 samples per provider, observable third-party search demand, and a public /products/[slug] page on OCB. Editorially curated pairs (like this one) may publish early when search demand is high and data is accruing — panels with fewer than 100 samples are shown as provisional. The full pair ledger is versioned in the public repo.
