A new draft proposal for @SeiNetwork would cut the time needed to withdraw staked $SEI from 21 days to 7. Called SIP-7, the proposal remains in draft form and is open for community feedback on GitHub.
What SIP-7 Would Change
According to a draft pull request in the sei-protocol/sips repository, SIP-7 would shorten the pacific-1 unbonding period from 21 to 7 days. It would make the change through a single governance proposal updating the staking/UnbondingTime parameter. No software upgrade is required, so the change depends solely on a successful governance vote.
Unbonding is the waiting period that starts when a holder withdraws staked tokens. Sei's staking documentation says tokens do not earn rewards during this period and cannot be transferred. The proposal describes this as a price risk for stakers, who cannot sell while they wait.
The draft also sets out transition rules. Undelegations and redelegations already underway when the proposal is executed would retain their original 21-day completion period. As a result, withdrawals requested before the change takes effect would not get the shorter waiting period.
Technical and Security Considerations
The unbonding period also serves a security purpose in proof-of-stake networks, and the draft addresses related parameters. It notes that a 7-day unbonding period would remain longer than the 3-day governance voting period and the 48-hour maximum age for evidence.
Node operators using state sync would need to set their trust period at 112 hours or less, equivalent to two-thirds of the new unbonding period. The draft says sei-chain v6.8 fixes the trust period at 112 hours and removes the setting, meaning operators can no longer configure it. The SIP also provides migration notes for contracts, wallets and node operators.
Sei is not the first network to consider this trade-off. A separate governance proposal for XPLA argued that a 21-day wait limits delegators' liquidity, while maintaining that a shorter period could still leave time to detect and penalize validator misbehavior.
SIP-7 is still a draft, and its terms could change before a vote is scheduled. Holders and node operators can review the proposal and provide feedback through the Sei SIPs repository on GitHub.
