XP Staking (Union Vault)

XP Union Vault is a non-custodial staking vault that turns the real earnings of the Foundation's Union validator node into staker rewards and permanent XP burn at the same time.

Stake, claim, and unstake at stake.x-phere.com. Live protocol state: /status.html · Burn record: /burn.html

What Makes It Different​

PillarWhat it means
① Real yieldRewards are not newly minted. They come from validator rewards the Union node actually earned.
② DeflationaryMore than 40% of every day's rewards are permanently burned to 0x…dEaD.
③ Non-custodialYour principal is never re-deployed or re-staked. It stays yours and is withdrawable in full.

How the Split Works, in One Line​

Each day, the rewards that flowed into the vault are split by how full the cap is:

staker allocation = inflow × 60% × (staked ÷ cap)
everything else   = burned

Every staker is paid for their own seat only, so your APR does not depend on how many others join. The yield attached to empty seats is burned. See How It Works.

caution

APR varies with the node's earnings and is not guaranteed, and staking a smart contract carries risk. All example figures in these pages are illustrative. Read Fees & Risks before staking.
