TL;DR
Everstake runs a validator on the Sei network, so Sei staking through Everstake is non-custodial delegation.
Full staking details ↓
SEI is the native token of Sei, a parallelized EVM layer-1 that produces a block about every 400-460 ms.
The delegated SEI stays in the holder's own wallet, and Everstake cannot move or spend it. Everstake charges a 5% commission on staking rewards, deducted from rewards so the delegated amount stays intact.
There is no minimum stake. Unstaking takes 21 days, during which the SEI generates no rewards and cannot be transferred.
Sei does not slash delegated SEI, because the on-chain slash fractions for double-signing and downtime are 0%. The current reward rate is 3.99%.

How to stake SEI with Everstake in 4 steps
Delegating SEI to Everstake takes 4 steps in the Sei Dashboard.
- Open the Sei Dashboard staking page and connect an EVM wallet that holds SEI.
- Select Everstake and compare the validator address with seivaloper1ummny4p645xraxc4m7nphf7vxawfzt3p5hn47t.
- Enter the amount of SEI and confirm the delegation transaction in the wallet.
- Claim rewards from the dashboard as they accrue, or undelegate to start the 21-day unbonding period.
Sei staking wallets in 2026: what works after SIP-3
Sei is consolidating to an EVM-only stack under SIP-3, so Sei staking now works with EVM wallets and the Sei Dashboard.
Keplr uses Cosmos-format sei1 addresses, and Sei documentation tells Keplr users had to move assets to an EVM 0x address before the cutover date: Oct 26, 2026. Delegations on associated addresses stay accessible afterward through the Sei Dashboard.
Holders with unassociated addresses must associate them or undelegate, which takes 21 days. Check out the official Sei SIP-03 migration guide for the steps.
How Sei staking rewards work: per-block accrual and 5% commission
Sei distributes staking rewards to delegators in proportion to their delegation, and the validator keeps a commission, which is 5% for Everstake. Sei documentation states that bonded SEI starts earning rewards immediately.
Rewards accrue per block, about every 400-460 ms, as a balance the delegator claims. The commission comes out of rewards, so the delegated SEI stays untouched.
Risks of staking SEI: 21-day unbonding and no slashing
Undelegated SEI cannot be transferred or sold for 21 days and earns no rewards in that time. The holder carries SEI price movement during the wait, while redelegating to another validator is instant.
Sei does not slash delegated SEI, and on-chain governance sets the slashing parameters and can change them. A validator that is jailed, or that ranks outside the 40-validator active set, earns no rewards for its delegators.
Sei network: 400 ms blocks, Sei v2 and the Giga roadmap
Sei was built on the Cosmos SDK and is now a parallelized EVM layer-1 with blocks of about 400-460 ms and an optimized Tendermint consensus called Twin Turbo.
Sei v2, the parallelized EVM upgrade, is live on mainnet.
The Giga upgrade is rolling out in phases: Sei v6.6 brought the first Ares execution and Eidos storage components to mainnet on August 4, 2026, and the Autobahn consensus testnet is next.
Sei Labs tracks progress live at giga.seilabs.io, and Sei Giga upgrade: 50x faster execution for the EVM era covers the design.
SEI tokenomics: how the 10 billion supply is allocated
SEI has a fixed maximum supply of 10,000,000,000 tokens, allocated at the August 2023 mainnet launch.
| Allocation | Share |
|---|---|
| Ecosystem Reserve | 48% |
| Private sale | 20% |
| Team | 20% |
| Foundation Treasury | 9% |
| Launchpool | 3% |
