How does Sui compare with Aptos?

Sui (SUI) and Aptos (APT) are both Move-language Layer 1s built by former Meta/Diem engineers — but they diverge in design, valuation, and current market momentum.

Market Snapshot

How they differ

Architecture. Both use the Move language for safety, but the execution model differs. Sui organizes data into independent objects, enabling parallel execution (its selling point for throughput). Aptos uses a more traditional account-based model with parallelized transactions via Block-STM. Same roots, different approaches to scaling.

Valuation & scale. Sui is far bigger on every metric here — roughly 6.5× Aptos's market cap and 6× the daily volume, with materially higher sentiment and a positive (long-leaning) funding rate on Binance Futures versus Aptos's slightly negative one. Both are mid-cap L1s, but Sui sits comfortably in the top-40 while Aptos sits around #108.

Supply. Sui: ~4.07B circulating of a 10B total/max. Aptos: ~858M circulating of a ~2.1B max. Aptos's supply is fully minted at max; Sui's remaining ~5.9B is still to unlock over time — relevant if you care about future supply pressure.

Where both trade

Both are verified on the same set of our curated exchanges:

• Binance — 0.10%/0.10% maker/taker
• OKX
• Bybit — 0.10%/0.10%
• Bitget — 0.10%/0.10%
• MEXC — 0.00% maker / 0.05% taker (cheapest fees)
• KuCoin — 0.10%/0.10%

Neither project's own news feed returned fresh headlines this turn, so there's no specific catalyst to point to behind today's moves.

Risk factors. As with any mid-cap L1, both carry general volatility and (for Sui especially) a large portion of supply still to be released. Team identity and token unlock schedules aren't verifiable from the data available to me — treat any claim about either as unconfirmed. This is a factual comparison, not a recommendation — the pick depends on whether you value Sui's larger, more liquid market and momentum or Aptos's lower valuation and fully-minted supply ceiling.
