Sei Labs published the first concrete piece of its rebuild roadmap on Friday. The post names two components, Ares and Eidos, and puts both in the 6.6 release. Sei Giga is the project those two belong to, and its whitepaper set the targets in May 2025 at 5 gigagas of throughput, roughly 200,000 transactions per second, and finality under 400 milliseconds.
The chain those numbers are written for settled 11,299 transactions in the 24 hours to August 2.
Ares takes over execution, Eidos pulls the history out
Ares is a rebuilt execution client running an EVMC backend with evmone as its interpreter. Sei says in the 6.6 announcement that it becomes the default execution path on mainnet, with the older v2 engine held in reserve for transactions Ares cannot process cleanly. Every upgraded node runs it unless the operator opts out.
Eidos handles the storage half. Today EVM history and Cosmos state share one database, so a node answering a query about an old block competes with whatever is arriving that second. Eidos gives EVM history a database of its own. Consensus, the third part of Sei Giga, comes later and has no date attached.
Version 6.6 is still a governance proposal, not an activated upgrade.
What the network actually processes
DefiLlama counted 2,317 active addresses on Sei across the same day, 1,101 of them new. Those 11,299 transactions work out to about 0.13 a second. The Sei Giga target sits roughly 1.5 million times above the volume the chain moves now.
| Measure | Sei on August 2, 2026 |
|---|---|
| Transactions, 24h | 11,299 |
| Active addresses, 24h | 2,317 |
| DEX volume, 24h | $4.53 million |
| DeFi TVL | $47.1 million |
| Chain fees, 30 days | $442,408 |
| Giga throughput target | 200,000 per second |
Fees carry the same shape. Sei collected $442,408 across 30 days, near $14,700 a day, against a token worth $290.7 million. Applications sitting on the chain pulled $38,774 in fees in a single day, several thousand times what the base layer earned over that window. Aave ran a version of this arithmetic on other chains last week, cutting Sonic while keeping Celo, and the comparison Coinliva drew on Manta in June used the same measure.
Ondo holds most of the money on Sei
Stablecoins on Sei total $309.06 million. That beats the SEI token's own market value. It also runs to about six times the DeFi capital locked on the chain, and 82.98% of the float sits in one asset, USDY, the tokenized Treasury note from Ondo, worth close to $256 million. Paper parked in a wallet to earn yield barely transacts, whatever the client underneath it can do.
SEI traded at $0.04317 on Sunday. That is 8.6% up over seven days and 13.2% over thirty, according to CoinGecko. Its all-time low of $0.04162 was printed on July 28, five days before the 6.6 proposal went up. It has clawed back 3.7% since. The marker worth watching next is the consensus component, which Sei has not scheduled.
