Three chains, one language origin
Sui, Aptos, and Sei all trace engineering lineage back to Meta's Diem initiative, which produced the Move programming language. Move emphasizes resource-oriented programming and formal verification, making it attractive for high-value financial apps.Sui launched in May 2023 with an object-centric data model and parallel execution engine. Aptos launched in October 2022 with a focus on modular consensus and institutional reliability. Sei started as a Cosmos SDK chain with a trading-focused order book, then added EVM compatibility in its v2 upgrade.
The sui vs aptos vs sei 2026 comparison is less about raw Move support and more about how each team has differentiated on ecosystem, token design, and distribution. Our earlier piece on best crypto to buy 2026 flagged all three as cycle candidates.
TVL and ecosystem comparison
Total value locked is the clearest signal of where real capital is flowing. The numbers below are pulled from DeFiLlama dashboards in April 2026.- Sui: 2.1 billion dollars TVL, led by Navi Protocol, Cetus, and Scallop
- Aptos: 1.4 billion dollars TVL, led by Echelon, Thala, and Aries Markets
- Sei: 780 million dollars TVL, mostly on Yaka Finance and DragonSwap
Sui has pulled ahead on consumer applications. Games like Sui8192 and collectible platforms on Sui have driven daily active wallets above 1.4 million, according to CoinGecko data from March 2026.
Aptos has focused on payment rails and institutional tokenization. Mastercard's cross-border stablecoin pilot settled on Aptos in Q4 2025, and Microsoft uses Aptos for a digital identity proof-of-concept.
Performance and developer activity
Throughput claims look similar across all three chains, but live numbers differ significantly. Real-world sustained throughput matters more than theoretical peak TPS.Sui sustains roughly 5,000 transactions per second under normal load with sub-second finality. Aptos averages 3,200 TPS with 700 millisecond finality. Sei's EVM fork clocks in around 2,400 TPS on the execution layer with a two-block finality.
GitHub activity paints a clearer picture of long-term viability. Sui has 340 active monthly core contributors in 2026, Aptos has 280, and Sei has 110. Developer mindshare matters because it predicts the next wave of applications.
- Sui: 5,000 TPS sustained, 340 monthly core contributors, Move-native
- Aptos: 3,200 TPS sustained, 280 monthly core contributors, Move-native
- Sei: 2,400 TPS on EVM, 110 monthly core contributors, EVM + optional CosmWasm
Token economics and unlock pressure
Every sui vs aptos vs sei 2026 analysis needs to address token unlocks. All three launched with significant allocations to insiders and foundation reserves, and those allocations are still vesting.Aptos has the heaviest schedule. Roughly 18 percent of circulating supply is set to unlock between April 2026 and April 2027, which has kept APT trading in a narrow range despite ecosystem wins. Sui unlocks about 13 percent over the same period.
Sei's schedule is lighter at 8 percent, but most of its float is already circulating. That limits supply pressure but also caps the narrative upside from new unlocks creating scarcity stories.

Which one belongs in a 2026 portfolio
Picking one chain over the others depends on your thesis. If you believe consumer apps and on-chain gaming will drive the next wave, Sui has the strongest traction.If institutional adoption and payment rails matter most, Aptos has the partnership momentum and the cleaner regulatory posture. The Mastercard pilot and the Microsoft identity work are harder to replicate than a DEX launch.
Sei is the speculative leg of the trade. Its EVM pivot opens it to Solidity developers but arguably dilutes the Move-native thesis. Self-custody matters for all three, so review our ledger vs trezor 2026 guide before holding meaningful size in any of them.
FAQ
Which chain has the most active users in 2026?
Sui leads with 1.4 million daily active wallets in March 2026, driven by consumer apps and gaming. Aptos follows with roughly 900,000, and Sei sits near 310,000.
Is Sei still a Move-based chain?
Not in the same way. Sei v2 added full EVM compatibility in late 2024 and most new dApps on Sei are now Solidity-based. Move support remains available but is no longer the primary developer path.
Can all three chains coexist long term?
Probably, but not all three will deliver outsized returns. L1 markets tend to consolidate around one or two winners per thesis, which is why the sui vs aptos vs sei 2026 comparison matters for portfolio sizing rather than just narrative allocation.
