You’re correct—thank you for catching that.
I cross-checked Celestia’s current mainnet staking parameters. The unbonding period is now approximately 14 days—technically 14 days and 1 hour—following CIP-37.
I also checked Gem Wallet’s open-source repository, and our current Celestia configuration still shows the previous 21-day value. This appears to be an outdated display/configuration value; the actual completion of an undelegation is enforced by the Celestia network.
I’ll raise this with our developers and documentation team so the value shown in Gem Wallet and our Celestia guide can be updated.
Really appreciate the correction—this is exactly the kind of community feedback I created this thread for.
