Why transactions get stuck

A Conflux transaction stalls in "pending" status for one of these reasons:

  • Gas price too low — network congestion priced your transaction out
  • Storage collateral missing — Core Space transactions require enough CFX to cover storage; insufficient collateral causes the network to refuse
  • Nonce conflict — another transaction with the same nonce was sent and is racing yours
  • RPC node failure — your wallet's RPC endpoint went down before the transaction was actually broadcast
  • Insufficient balance for gas — the wallet showed enough CFX but didn't reserve enough for the gas fee

Quick fixes (Conflux Wallet)

If you're using Conflux Wallet:

  1. Open Transaction History.
  2. Find the pending transaction.
  3. Tap Speed Up (replaces with a higher gas price) or Cancel (replaces with a zero-value transaction at the same nonce, which voids the original).
  4. Sign. Wait one block.

That's the entire procedure inside Conflux Wallet.

Manual recovery (Fluent or other wallets)

If you're using Fluent or another wallet that doesn't have a built-in Speed Up / Cancel button, here's the manual procedure:

  1. Find the stuck transaction's nonce. On confluxscan.org (Core Space) or evm.confluxscan.io (eSpace), look up your address. Find the pending transaction. Note its nonce.
  2. Send a replacement transaction with the same nonce. In your wallet, enable advanced send (Fluent: toggle Advanced in the send screen). Set the nonce manually to the same value as the stuck transaction. Set a higher gas price (1.5–2× the original).
  3. Choose what the replacement does. Replace the original action — same recipient and amount, just higher gas — and the original gets dropped. Or cancel by sending to your own address with zero amount at the same nonce; the original gets voided.
  4. Submit and wait. The replacement transaction races the original. Whichever gets mined first wins; the loser is dropped.

When the transaction shouldn't be stuck — but is

If you've tried the above and the transaction is still stuck:

  • Check your RPC endpoint. In Conflux Wallet, Settings → Networks. Switch to a different endpoint and retry.
  • Wait for chain congestion to ease. During major network events, all transactions slow.
  • Check storage collateral. For Core Space transactions, you may need to lock more CFX as collateral.
