XDC Liquid Staking V3
What changed in V3?
V3 is a non-custodial ERC-4626 vault. Rewards auto-compound into the exchange rate (no claim), and withdrawals are self-service via a queue you control directly. There is no admin in your withdrawal path.
What is psXDC V3?
psXDC V3 is your share of the vault. The number of shares you hold stays constant; what each share converts to in XDC grows over time as validators earn. Standard ERC-20, transferable, usable in DeFi.
Where can I use psXDC V3?
- Trade on DEXs (paired with XDC).
- Deposit into XDC NFTs to boost APY.
- Hold passively. The exchange rate increases on its own.
How It Works
Stake flow
- Deposit XDC into the V3 vault.
- Receive psXDC shares minted at the live exchange rate.
- Your shares accrue value automatically. No further actions required.
Withdraw flow (self-service)
- Choose how much psXDC to redeem.
- If the vault holds enough liquid XDC, you receive it in the same transaction (instant).
- Otherwise, your request is queued while XDC is unstaked from validator nodes. Watch its position from the queue list.
- Once processed, hit “Claim All Ready XDC”. A single tx pays out everything that's ready.
- You can cancel a queued (not yet processed) request at any time and get your shares back.
Rewards flow
Validators send rewards to the vault (the XDC network usually pays them around the first day of each month). The vault's total assets grow while the number of psXDC shares stays constant, so each share is worth more XDC. That's it. No claim flow. The team's target is about 5.5% APY - an estimate, not a guaranteed rate.
Migration from V2
- Approve the migration bridge to spend your V2 psXDC.
- Migrate: the bridge burns your V2 tokens and mints V3 shares to your wallet at the live quote.
- Slippage tolerance default is 0.5%. The UI shows a quote so you can compare.

Basics
5Anyone holding XDC. There is no minimum on the user side; only the protocol-level masternode minimum applies when funds are deployed to validators.
The team's current target is about 5.5% APY. This is an estimate based on XDC network validator rewards, not a guaranteed rate - actual returns depend on how much the network pays out and when. Rewards land in the vault (usually monthly) and show up as a rising psXDC exchange rate rather than separate payments.
No. V3 is an ERC-4626 vault. Rewards collected from validators are added to the vault's total assets, which raises the exchange rate of psXDC against XDC. Your psXDC balance stays constant; what each share is worth grows over time.
V2 was custodial: an admin had to approve withdrawals and rewards were paid out as separate XDC transfers you had to claim. V3 is non-custodial: withdrawals are self-service (instant when buffer covers them, otherwise queued and self-claimed once processed), and rewards are baked into the share price, so there is no claim button.
Yes. psXDC V3 is a standard ERC-20. Transferring it transfers the entire underlying claim on the vault, and the recipient inherits the auto-compounding rewards.
Withdrawals
2If the vault holds enough liquid XDC to cover your request, the withdrawal is instant in the same transaction. Otherwise, your request enters a queue while XDC is unstaked from validator nodes (the network's unbonding period is roughly 30-38 days). Once processed, you call "Claim All Ready XDC" to receive your funds. The queue page shows your position and the team's estimated completion date.
Yes. As long as your request hasn't been processed yet, you can cancel it from the Withdrawal Queue list, and your shares are returned to your wallet immediately.
Migration & V2
1You can convert it at the migration bridge at close to 1:1 - the exact amount follows the live quote, with a configurable slippage tolerance (default 0.5%). The bridge burns your V2 tokens and mints V3 shares to your wallet. The UI shows a banner and an auto-popup modal whenever a V2 balance is detected. The bridge remains open for late migrators, so there is no deadline to beat - but rewards only accrue on the V3 side.
Security & Contracts
2Yes. The vault has explicit roles: Operations Manager (pause/unpause, buffer), Risk Manager (loss reporting + ceilings), Migration Manager (migration toggle), Proposer (masternode proposals). All sensitive role rotations and threshold changes are time-locked behind the governance delay.
Two: the V3 vault itself (PrimeStakedXDC_V3_2, ERC-4626 - this contract is also the psXDC token) and the migration bridge (PrimeStakedXDC_V3MigrationBridge). The vault address is linked from the Vault Overview card on the home page; the bridge address is shown on the Migration page.
