psXDC is native to the XDC Network, but you can bridge it to Base, Arbitrum, BNB Chain, and HyperEVM to put it to work in DeFi there — lending it on PrimeFi, providing liquidity, or simply holding it on the chain where the rest of your portfolio lives. Bridging uses LayerZero V2, not a third-party custodian.
See Multichain psXDC: DeFi Opportunities for what you can do with psXDC once it is bridged.
Your stake keeps earning while it is bridged. psXDC is non-rebasing: your balance stays the same number, but each psXDC is redeemable for more XDC over time as validator rewards compound into the vault share price. Bridging does not pause or forfeit that yield — you capture it when you bridge back.
How to bridge (step by step)
The Bridge page is at stakexdc.com/xdc-liquid-staking/bridge.
- Connect your wallet. The page works from any of the five supported networks; it will ask your wallet to switch when needed.
- Pick the route. Choose the source chain under From and the destination under To (routes always run through XDC: XDC ↔ Base/Arbitrum/BNB/HyperEVM). The circular arrow button flips the direction. Clicking a chain card in the balance strip below also selects it as the source.
- Enter the amount (or press Max). The LayerZero fee quotes itself automatically and is shown in the route details, along with the estimated delivery time.
- Press Bridge.
- Bridging out of XDC for the first time asks for one extra approval transaction (the lockbox needs permission to hold your psXDC).
- The bridge transaction itself carries the LayerZero fee as native gas (XDC when leaving XDC; ETH/BNB/HYPE when coming back).
- Track delivery. A tracker card appears with a progress bar and a LayerZero Scan link. Delivery normally takes 2–5 minutes (four independent verifiers must each confirm 20 source-chain blocks). The page detects arrival automatically and refreshes your balances.
Fees
| What | Who charges it | Rough size |
|---|---|---|
| LayerZero message fee | LayerZero (DVNs + executor) | a few XDC leaving XDC; small ETH/BNB/HYPE returning |
| Bridge fee / spread | None — StakeXDC takes nothing | 0 |
| Amount received | 1:1 | what you send is what arrives |
How it works (lockbox)
psXDC has a single, canonical supply. When you bridge out, your real psXDC is
locked in the PsxdcOFTAdapter on XDC and an equal amount of psXDC is
minted on the destination chain. Bridging back burns the destination
psXDC and unlocks the original on XDC. Total psXDC across all chains never
changes.

What you can and cannot do with bridged psXDC
| On XDC | On Base / Arbitrum / BSC / HyperEVM |
|---|---|
| Stake / unstake through the vault | No — bridge back to XDC to unstake |
| Count toward the referral program | No — referral reads balances on XDC |
| Hold, transfer, DEX-LP | Hold, transfer, DEX-LP, use as collateral on PrimeFi (Base & HyperEVM) |
Seeing your yield on other chains
A wallet on Base/Arbitrum/BSC/HyperEVM shows a fixed psXDC balance — the growth is in the redemption rate, not the count. StakeXDC publishes that rate to each chain through the psXDC rate oracle; the app's Bridge page shows the current XDC value of your bridged balance.
Security
- Every pathway is verified by four independent DVNs (Canary, LayerZero Labs, Horizen, and Nethermind) — a single compromised verifier cannot forge a bridge message.
- The adapter meters the unlock path with a per-source-chain rate limit. Because the lockbox only ever releases funds when psXDC is bridged back, the limit is applied there (keyed by the origin chain): even if one destination chain were fully compromised, it could unlock at most the configured burst immediately and a fixed rate thereafter, giving operators time to pause — while the other chains' pathways are unaffected.
- Total bridged psXDC across all chains always equals psXDC locked in the adapter — verified by an on-chain conservation test across multi-hop routes (XDC to Base to Arbitrum and back), including sub-1e12 dust round trips.
- Contracts use two-step ownership transfer (nominate + accept), so ownership cannot be fat-fingered to an address that cannot operate the lockbox.
Troubleshooting
- Transfer not arrived after 10+ minutes? Open the LayerZero Scan link from the tracker card (or paste your transaction hash at layerzeroscan.com). Messages are never lost — delivery is retried automatically once verification completes.
- "Insufficient balance" on the fee? The LayerZero fee is paid in the source chain's gas token, on top of gas. Leaving XDC needs a few extra XDC; returning needs a small amount of ETH (Base/Arbitrum), BNB, or HYPE.
- Wrong network in the wallet? The page requests the switch automatically when you press Bridge; approve the prompt in your wallet.
