Overview

Non-custodial XDC staking infrastructure. No principal-stake slashing.

PrimeStaking runs on the PrimeStakedXDC_V3_2 vault, a fully non-custodial, ERC-4626 share-based design with self-service withdrawals. In July 2026 the vault was redeployed as V3.2 and every V3.1 holder's balance was mirrored 1:1 via a snapshot airdrop; no user action was needed. The XDC NFT vault was repointed to the V3.2 token in the same operation and gained multiple lock tiers. V2 holders who never migrated can still do so through the migration bridge; legacy NFTs migrate via Migrate XDC NFTs to V3.

Overview

PrimeStaking is a non-custodial staking platform and infrastructure provider on the XDC Network, built in collaboration with Nethermind and the XDC Core team.

The platform is live at primestaking.xyz.

How It Works

XDC Liquid Staking

XDC

~4.5% APY

Stake XDC, receive psXDC vault shares. Share price grows as validator rewards accrue.

XDC NFTs

psXDC

~4.5% base + boost slice → up to ~6% locked

Deposit psXDC shares into NFTs. Earn the underlying NAV plus a rarity- and lock-weighted boost slice.

XDC Liquid Staking

The simplest way to earn on your XDC. No NFT required. No minimum amount.

Stake XDC - Deposit any amount into the V3 vault.
Receive psXDC shares - You receive psXDC at the current vault exchange rate. There is no fixed 1:1 ratio; share price rises as rewards accrue.
Earn rewards - Rewards are embedded directly in the share price (~4.5% APY). There is no claim button; your shares simply become worth more XDC over time. Rewards accrue continuously at any backing level (the V3.2 permanent-ledger model).
Stay liquid - psXDC is a standard ERC-20 on the XDC Network. Hold it, transfer it, use it as DeFi collateral, or deposit it into XDC NFTs.
Withdraw anytime - Burn psXDC shares. If the vault has enough unencumbered liquidity, you receive XDC instantly in the same transaction. Otherwise your request enters an automatic FIFO queue and you claim once masternode payouts return.
Refer friends - Share your invite link; when someone stakes for the first time through it, you earn a share of the protocol fee their staking generates. See Referral Program.

XDC NFTs

A gamified staking layer on top of liquid staking. Deposit psXDC shares into collectible NFTs to earn two stacked yields.

Each NFT has a rarity (Plentiful → Handcrafted) that determines its weight in the boost accumulator.
Base yield comes from the underlying psXDC share price growing over time (~4.5% APY).
Boost yield comes from a Synthetix-style accumulator. The protocol's XdcNftBoostHarvester calls notifyBoost and the resulting slice is distributed pro-rata to NFT weights.
Level up by merging two same-rarity NFTs into a higher tier.
Lock your NFT for a fixed period to add a lock bonus to its weight. Four tiers are available - 30, 90, 180 or 365 days - with progressively larger boosts. The boost applies for the whole lock and ends when the lock expires; you can re-lock afterwards. Floor is the ~4.5% base NAV (always earned, no claim); with the boost stream flowing, combined APY ranges from ~4.75% (unlocked) up to ~6% (365-day lock).
You only claim the boost slice from the app. Base NAV is automatically inside the shares you get back on withdraw.

Partner Staking

Deploy and self-manage your own liquid staking pool, listed in the PrimeStaking app. Flat 15% protocol fee.

Communities, validators, regional platforms

White Label and Powered by Prime are integration tracks where you embed the flagship PrimeStaking vault (see For Partners below). Partner Staking is a distinct, self-service product where you run your own vault (see Partner Staking).

Why Partners Choose PrimeStaking

No principal-stake slashing - XDC's slashing mechanism penalizes downtime via temporary exclusion from block production (~2h) and missed rewards; principal stake is never burned, unlike ETH-based protocols.
ERC-4626 vault - psXDC v3 conforms to the same standard used by major DeFi protocols, making integration straightforward.
Non-custodial - smart contract-based validator custody, no third-party key management, no admin mint or ownerWithdraw.
Audited infrastructure - QuillAudits (98.8%) on the V1 liquid staking contracts; Nethermind Security NM-0843 (published May 08, 2026) on the psXDC V3 vault and V3 Migration Bridge.
Nethermind Security - trusted auditing partner for Lido, EtherFi, Optimism, and Worldcoin.
Battle-tested - live since 2024 with $6M+ TVL.
Revenue sharing - transparent, on-chain fee model.

Security

PrimeStakedXDC_V3_2 is non-upgradeable, deployed with a regular constructor and no proxy. The vault logic cannot be modified after deployment. The referral contracts (ReferralRegistry, ReferralRewards) are likewise non-upgradeable satellites; they never hold user principal.
The XDC NFT staking vault is a TransparentUpgradeableProxy controlled by the protocol multisig, with namespaced ERC-7201 storage. All other NFT-stack contracts (collection, migrator, harvester, bypass facet) are non-upgradeable.
Validator custody is smart contract-based - permissionless and trustless, no third-party custodian.
The protocol is non-custodial - users retain full ownership of their assets at all times.
Infrastructure developed with Nethermind and the XDC Core team.
