General Questions

What is XDC Liquid Staking?

XDC Liquid Staking enables you to stake XDC while retaining full liquidity. Instead of locking up your tokens, you receive psXDC (Prime Staked XDC) — an ERC-4626 vault share that can be freely used or traded in DeFi.

• XDC Liquid Staking: A straightforward way to stake XDC and receive psXDC vault shares — no minimum required. Earns ~4.5% APY through share-price appreciation.

• XDC NFTs: Deposit psXDC shares inside XDC NFTs to layer a boost slice on top of the base NAV. Floor stays at the base ~4.5% (always earned, regardless of rarity / lock / boost cadence); when the boost stream is flowing, the combined APY ranges from ~4.75% (unlocked) up to ~6% (locked).

What is psXDC?

psXDC is an ERC-4626 vault share representing your position in the V3 staking vault. You don't claim rewards separately — the share grows in value over time (totalAssets / totalShares increases as validator rewards accrue), so each psXDC is worth more XDC the longer you hold it.

Where can I trade psXDC?

You can trade psXDC on the XSWAP DEX on the XDC Network, paired with XDC. Purchasing psXDC directly also benefits you, since holding it means owning the appreciating share.

What happens when I unstake?

When you decide to unstake, you burn the corresponding psXDC shares. The app calls redeemWithQueue which:

• Settles instantly when the vault's liquid buffer (default 5% of total assets) covers your request — XDC returns to your wallet in the same transaction.

• Enters a permissionless FIFO queue otherwise — your shares are escrowed and a request is created. As soon as the buffer is replenished (new deposits, reward inflows, masternode resignations) the queue settles your request. For very large redemptions the upper bound is the network's candidateWithdrawDelay — approximately ~35 days under typical block times.

You can cancel queued requests any time, and if a payout ever fails the XDC lands in pendingQueuedAssets so you can collect it via claimQueuedAssets.

→ Withdrawals: Instant vs Queued

Can I transfer my staking position?

Yes.

• Liquid Staking: Send psXDC to another address — the recipient inherits the appreciating share. No further action needed.

• XDC NFTs: If your psXDC is staked inside an XDC NFT, you can sell or transfer the NFT via PrimePort.xyz. The new owner inherits the staked shares, pending boost, and any lock status.

How are rewards distributed?

Product	Base reward	How you receive it
XDC Liquid Staking	~4.5% via psXDC share-price growth	Automatic — no claim button. Rewards are realized when you redeem or transfer the share.
XDC NFTs	Base ~4.5% (NAV) + boost slice (up to ~1.5% via Synthetix accumulator)	Base is automatic (same as liquid). Boost is claimed from the NFT detail page in the app, paid in XDC.

→ How Rewards Work → Reward Model: Base NAV + Boost

Is there any risk of slashing?

XDC Network does have a slashing mechanism, but it differs fundamentally from Ethereum's. A masternode that fails to sign any block during one full epoch (900 blocks, ~30 minutes) is excluded from block production for the next 4 epochs (~2 hours) and forfeits rewards during that window. Crucially, principal stake is not burned — staked capital is never destroyed by validator behavior. For psXDC holders this means a slashing event on a protocol masternode would only briefly slow the rate at which the share price grows during the exclusion window; it cannot reduce the value of the shares themselves. This is structurally different from Ethereum-based liquid staking, where slashing can permanently destroy a portion of staked ETH.

XDC NFTs

What are XDC Staking NFTs?

XDC Staking NFTs offer a gamified approach to staking. You deposit psXDC shares into an NFT, and the NFT's rarity, level, and lock status determine its weight in the boost accumulator. Higher weight = larger slice of every boost push.

How do XDC NFTs work?

1. Deposit psXDC shares: acquire psXDC (by staking XDC or buying on a DEX) and deposit it into your NFT.

2. Earn base NAV: the underlying psXDC shares keep appreciating as the vault accrues validator rewards — same ~4.5% you'd get without the NFT.

3. Earn boost: each notifyBoost push from the protocol's harvester credits the Synthetix accumulator; your NFT's pending boost grows proportionally to its weight.

4. Claim boost: from the NFT detail page, in XDC.

5. Merge: combine two NFTs of the same rarity to create a higher-rarity NFT with a bigger weight.

6. Lock (optional): locking adds lockBonus to the weight, which can push the combined APY toward the ~6% top of the band, but disables withdraw / merge / burnAndRedeem until expiry. The base ~4.5% applies whether you lock or not.

What is the Merge System?

If you have two NFTs of the same rarity, you can merge them into one NFT of the next rarity tier. Both originals are burned and a new one is minted. Higher rarity means a bigger rarityMultiplier and a bigger slice of every boost push. Because merging burns NFTs, the collection becomes more scarce over time — making remaining NFTs increasingly valuable.

How do I sell my XDC NFT?

List or auction your XDC NFT on PrimePort.xyz. When purchased, the buyer gains the NFT itself plus the full staking position attached to it — staked psXDC shares, pending boost, weight, and any lock status all travel with the NFT.

I still hold a legacy XDC NFT — what should I do?

You can keep it (the legacy contracts remain operational) or migrate it to V3 in a single transaction via /xdc-nfts/migrate. Migration preserves your rarity and any active lock expiry, and your tokenId for legacy ids below 10000 (ids ≥ 10000 are remapped into the 5558–9999 band because that range is reserved for merged NFTs). It immediately starts earning under the V3 reward model.

XDC Liquid Staking

How does Liquid Staking work?

1. Stake XDC through the V3 vault (stake() payable, or depositNative(assets, receiver)).

2. Receive psXDC shares at the current exchange rate.

3. Watch the share price grow — rewards are embedded in the share. No claim needed.

4. Withdraw by calling redeemWithQueue: instant when the buffer covers it, queued FIFO otherwise. Or swap on XSWAP for an immediate market exit.

Who can participate?

Anyone. There is no minimum XDC required. It's accessible to all XDC holders.

How do I withdraw my staked XDC?

You have two options:

• Protocol redemption (redeemWithQueue): burns the equivalent psXDC shares. Instant when the vault's liquid buffer permits, otherwise enters the on-chain FIFO queue with self-claim via claimQueuedAssets. You can cancel queued requests at any time before settlement.

• Instant DEX exit: swap psXDC for XDC on XSWAP DEX for immediate liquidity at market price.

Can I transfer my Liquid Staking position?

Yes. Send psXDC to another address — whoever holds the share owns the appreciating position. No NFT required.

I still hold V2 psXDC — how do I get V3?

Use the V2 → V3 migration bridge. Approve PrimeStakedXDC_V3MigrationBridge, call migrate(amount, minSharesOut), and your V2 tokens are burned and V3 shares minted in the same transaction with slippage protection.
