Unable To Claim Staking Rewards;​

  1. If you can't claim the staking rewards on the portal. Visit HERE.
  2. If the transferrable balance in the wallet is too low, you might not be able to claim the staking rewards. Top up your wallet and then claim the rewards.

After signing the transaction, the portal spins indefinitely;​

  1. If the portal spins indefinitely after you've signed a transaction, your transferable balance in the wallet is too low to pay for the transaction.
  2. Top up your wallet with new ASTR tokens and you'll be able to complete your transaction.

My staking is not displayed on the dApp Staking page of the Astar Portal ;​



  1. Two dApps have been delisted from the dApp Staking and if you were a staker on these dApps, you may not see your staking position on the dApp Staking page.
  2. dApps concerned:
    • Arthswap, contract: 0xE915D2393a08a00c5A463053edD31bAe2199b9e7
    • Sirius Finance, contract: 0x9448610696659de8F72e1831d392214aE1ca4838
    • ADAO, contract: 0x1de7c3A07918fb4BE9159703e73D6e0b0736CaBC
  3. To release these funds, you must claim all your pending ASTR rewards.
  4. Once all your pending rewards have been claimed, your tokens will be unlocked without any unbonding period and will become directly transferable.

"You do not have enough tokens to pay the transaction fee."​

  1. As the sentence indicates, you do not have enough transferable tokens to cover the transaction fees.
  2. Top up your wallet with new ASTR or SDN tokens and you'll be able to complete your transaction.
  3. Bear in mind that tokens locked in dApp Staking, vesting or reserved balances cannot be used to pay gas fees.

"No reponse received from RPC endpoint in 60s."​



  1. If you encounter this problem, it's probably due to a synchronization problem with the RPC endpoint used by the portal.
  2. To solve this problem, you need to reset the connection with the RPC by changing the Portal endpoint.
  3. On the Astar portal, click on the Astar logo in the top right-hand corner.
  4. Under Network, expand the advanced panel by clicking on the 3 dots.
  5. Modify the endpoint and click on the Change Network button to confirm your action.
