How does Sui compare with Solana?

Both are high-performance Layer 1s built for speed and low fees — here's how they actually line up right now.

Market snapshot

Solanasol#7 is far bigger and more established — a ~20x larger market cap and roughly 10x the daily volume. Sui is the much smaller, earlier-stage challenger.

How they work

• Solana uses Proof-of-Stake + Proof of History (a decentralized clock that timestamps transactions). It keeps a single unified ledger, runs thousands of TPS with sub-second finality, and trades at sub-penny fees. The Sealevel engine runs non-conflicting transactions in parallel.
• Sui (from Mysten Labs, founded by ex-Meta/Meta blockchain engineers) uses the Move programming language and an object-centric data model — data is organized into independent objects rather than one account ledger, which enables parallel execution and horizontal scaling to keep fees stable as the network grows. Backed by a16z, Coinbase Ventures, Circle Ventures, and YZi Labs.

Key differences at a glance

• Maturity: Solana has years of battle-tested uptime (and some famous outages), a deep DeFi/meme-coin ecosystem, and FTX/Alameda ties in its history. Sui is newer with a smaller but growing ecosystem.
• Supply: Solana has ~585M SOL circulating (inflationary, no hard max). Sui has ~4.07B of a 10B total supply in circulation — a large portion still to unlock over time.
• Both are "Made in USA," PoS L1s on the smart-contract-platform track.
• Funding: Both have slightly positive funding rates right now (Solana +0.004%, Sui +0.006% per Binance Futures) — perp markets mildly long on both.

Risk factors

• Sui has ~60% of its 10B max supply still not in circulation — supply schedule matters for an early-stage token, and no tool here can verify the actual unlock/vesting calendar.
• Solana is inflationary with no fixed max supply.
• Neither has a security object returned (both are large, widely-traded L1s — the GoPlus contract checks don't apply the same way as for DEX tokens).
• Neither team identity nor tokenomics schedules are verifiable through available data — standard caveat.

Where to trade both — they're listed on the same major exchanges, so you can hold either (or both) in one place:

Binance — 0.1%/0.1% — futures, beginners, API OKX — futures, beginners, API Bybit — 0.1%/0.1% Bitget — 0.1%/0.1% MEXC — 0%/0.05% maker/taker (cheapest fees here) KuCoin — 0.1%/0.1%

Bottom line: Solana is the proven heavyweight; Sui is the higher-risk, earlier-stage alternative with similar design goals (parallel execution, low fees) but a much smaller footprint and most of its supply still to unlock. Neither is inherently "better" — they're at very different points on the maturity/risk spectrum.
