How Do Sui and Aptos Compare in Speed, Fees, and User Experience? Sui and Aptos share a parent. Both grew out of the Diem project at Meta, and both write smart contracts in the same language.
Sui and Aptos share a parent. Both grew out of the Diem project at Meta, and both write smart contracts in the same language.
Yet the Sui vs Aptos debate keeps dividing developers, because each network answered the same design questions differently.
That split reaches ordinary users too. It shapes how fast a transfer settles, what a swap costs, and how easily a newcomer opens a wallet.
Sui and Aptos are layer-1 blockchains, meaning each runs its own validators and native coin. SUI pays fees and secures Sui through staking. APT does the same job on Aptos.
The Diem stablecoin project produced the Move programming language, built to treat digital assets as scarce items. The Sui vs Aptos split begins there. After Diem closed, former team members founded Aptos Labs and Mysten Labs, the company behind Sui.
Sui treats every asset as an object with an owner. Simple transfers of owned objects can skip full consensus. Sui's docs cover the object-centric model.
Aptos stores state in accounts and runs transactions with Block-STM. That engine assumes transactions can run in parallel, then re-runs the few that collide.

Both settle in well under a second, so fees are the closer call. The foundation behind Aptos estimates a stablecoin transfer at about $0.00014, even after governance raised fees tenfold.
A transaction shown in Sui's docs carried a computation cost of 0.001 SUI, under a tenth of a cent. Cost rarely settles the Sui vs Aptos question.
Sign-in shows the Sui vs Aptos user experience best. Sui's zkLogin opens an address with a Google-style login, and apps can sponsor gas so newcomers need no SUI first. Aptos offers keyless accounts with Google or Apple sign-in. Its docs warn that a compromised Google account puts the linked account at risk.
Sui currently holds more value locked in DeFi, while Aptos pulls ahead on stablecoins and tokenized assets. These figures come from on-chain trackers as of mid-November 2026.

Total value locked, or TVL, counts assets deposited in DeFi apps. It moves with token prices as well as deposits. Sui holds about three times the Aptos figure, yet it sits far below its earlier peak near $2.6 billion.
Lending markets Suilend and NAVI Protocol lead Sui with roughly $134 million and $127 million. On Aptos, the perpetuals exchange Decibel holds about $43 million. Tokenized real-world assets reach about $811 million on Aptos against $31 million on Sui.
Wallet choice has narrowed on Sui. Phantom dropped Sui support in September, and the Sui-only wallet Suiet is shutting down. OKX Wallet and Trust Wallet still cover both chains.
Only about 41% of the 10 billion maximum SUI token supply circulates by market cap against fully diluted value (FDV). FDV prices every token at today's rate, locked ones included.
The rest arrives through a multi-year token unlock schedule, with a tranche released each month. One recent tranche was 13.15 million SUI, about 0.32% of released supply.
Aptos tightened its rules instead. In March, governance approved a hard supply cap of 2.1 billion APT, cut staking rewards from 5.19% to 2.6%, and raised fees tenfold. In October, early investor and contributor vesting ended, and monthly releases fell from about 11.31 million to 4.54 million APT.
The cap is not a promise of scarcity. In a recent 30-day window, fee burns of about 175,000 APT trailed staking emissions near 1.5 million. A future vote could also change the cap.
Competition is the second risk in any Sui vs Aptos review. Both chains fight larger networks for developers. The Sui TVL drop and wallet exits show how fast momentum can fade, and bridged assets add smart contract risk on both.
Neither chain wins on every measure, so the Sui vs Aptos choice depends on the use.
Sui may suit:
Apps built around owned digital items, such as games
Users who want deeper lending markets today
Aptos may suit:
Stablecoin payments and tokenized real-world assets
Fast on-chain trading, including perpetuals
For a casual user, the Sui vs Aptos decision is simpler. Check which apps and wallets are actually needed, then pick the chain that supports them.
The Sui vs Aptos data points in two directions. Sui leads in DeFi depth. Aptos leads in stablecoin supply and tokenized assets, and its direction is clearer: payments, trading, and institutions.
Neither lead looks safe. Sui's TVL has fallen sharply, while Aptos has a small market cap and needs burns to outrun staking rewards.
A fair reading of the Sui vs Aptos contest is that Sui has depth to defend, and Aptos has traction to prove. This is analyst interpretation, not a prediction.
Sui has the deeper DeFi markets, while Aptos holds more stablecoins and comes with a capped token supply. Both chains keep transactions fast and cheap, and both let new users get started through social login.
In Sui vs Aptos, Indian buyers face the same rules on either token: a flat 30% tax on gains, plus cess, and 1% TDS on transfers. Tax does not separate the two.
Before choosing between Sui and Aptos, it’s worth checking a few things: upcoming token unlocks, the trend in Sui’s TVL, and which wallets support each chain.
