How It Works
Paste TX Hash
Copy the pending transaction hash from your wallet or block explorer and paste it here.
- Select the coin and network the transaction was sent on
- Works with any valid hash from that network
- Choose Accelerate to speed it up, or Cancel to stop it
Pay Small Fee
Pick a speed. The fee is shown before you sign, so there are no surprises.
TX Processed
Your transaction is accelerated or cancelled, and the result is shown on screen.
- Accelerate: the same transaction is re-sent with a higher gas price
- Cancel: the pending transaction is replaced so it never completes
- Works across every supported chain
Your keys never leave your wallet. Bitslow only asks you to approve.

Pick the outcome you need
Accelerate
Move a pending transaction forward without starting over.
- Re-submits with a higher fee
- Keeps the same transaction intent
- Works across supported networks
Cancel TX
Void a transaction you no longer want to go through.
- Sends a replacement back to your address
- Replaces the original transaction
- Only the public hash is needed
No keys required
Your wallet stays yours from start to finish.
- No private key or seed phrase
- Only the public transaction hash
- Non-custodial by design
Use Accelerate when a transaction is pending because the fee is too low for current network conditions.
Use Cancel TX when you no longer want the original transaction to confirm. A replacement sends the funds back to your address.
Bitslow never asks for your private key or seed phrase. Only the public transaction hash is needed to find your transaction.
Frequently Asked Questions
Why is my transaction pending?
Transactions stay pending when the fee you set is too low for current network conditions. Miners and validators prioritize higher-fee transactions, leaving low-fee ones waiting in the mempool.
What's the difference between accelerate and cancel?
Accelerate re-submits your transaction with a higher fee so it gets confirmed faster. Cancel submits a replacement transaction that sends the funds back to you, effectively voiding the original transaction.
Which networks do you support?
We support Ethereum, Bitcoin, BNB Chain, Solana, Polygon, Avalanche, Arbitrum, Optimism, Base, and Tron. Both acceleration and cancellation are available on all supported chains.
Is this safe? Do you need my private key?
Completely safe. We never ask for your private keys or seed phrase. We only need your transaction hash, which is public information already visible on the blockchain.
