Phantom Wallet “Unable to Send”: Fixing Transaction Broadcast Failures (2026)

Phantom Wallet users are encountering the “Unable to send” error after confirming cryptocurrency transfers, with the message displaying specific failed amounts and destination addresses. This error appears immediately after the user approves the transaction, indicating that while the wallet successfully constructed and signed the transfer, the broadcast to the blockchain network failed completely. The failure affects Bitcoin, Solana, Ethereum, and all supported networks, leaving funds in the wallet despite the user having initiated the send operation.

The Network Broadcast and Node Submission Failure

The “Unable to send” error originates from critical defects in Phantom’s transaction broadcast layer and network node connectivity. Latest versions of the app and extension contain RPC endpoint rotation failures where the wallet attempts to submit signed transactions to offline or overloaded nodes, resulting in immediate rejection before the transaction reaches the mempool. The network timeout configurations are set too aggressively for current blockchain congestion levels, causing the wallet to abandon valid broadcasts that would succeed with slightly longer wait periods.

Additionally, the transaction retry mechanism fails to properly handle nonce management across multiple submission attempts, creating “nonce too high” errors on subsequent retries even when the original transaction never reached the network. The mobile application’s background network permissions fail to maintain connections during the broadcast phase, interrupting TCP handshakes and leaving transactions signed but unsubmitted. For Bitcoin specifically, the wallet fails to properly serialize witness data for SegWit transactions, causing node rejection with “Unable to send” errors while consuming the UTXOs as if spent.

Solution

Solution 1: Install Phantom Previous Version

Resolution requires deploying the previous Phantom version that maintains stable network broadcasting and proper node connectivity.

Implementation steps:

1. Save your Secret Recovery Phrase from Phantom settings.
2. Remove the current installation to clear failed network configurations.
3. Install the previous functional version:
   • Extension: Download Phantom Extension v24.5.0 here (broadcast stable)
   • Mobile: Download Phantom APK v24.5.0 here (network submission functional)
4. Restore your wallet and attempt a test transaction.
5. Verify that transactions broadcast successfully and receive network confirmation.

Option 2: Contact Support

If you don’t want to solve it yourself, Support can help solve the problem, send a ticket and they will respond within 1 to 3 days.

Transaction Broadcasting Restored

Following deployment of the previous version, transactions broadcast reliably with proper node selection and adequate timeout handling. Users can send cryptocurrency to any destination without encountering “Unable to send” failures after confirmation, ensuring that signed transactions reach the blockchain network and process successfully.
