Phantom Wallet “Transactions Fail”: Resolving Broadcast and Execution Errors (2026)

Phantom Wallet users are encountering persistent “Transactions fail” errors across all blockchain operations, preventing any movement of assets from the wallet. This failure appears immediately upon attempting to confirm sends, swaps, token approvals, or dApp interactions, with the error message providing no specific diagnostic code or failure reason. The issue affects Solana, Ethereum, and Polygon networks uniformly, blocking users from transferring SOL, ETH, USDC, or any SPL/ERC-20 tokens to external addresses or exchanges.

The Transaction Execution Pipeline Failure

The widespread transaction failures stem from critical defects in Phantom’s current transaction assembler and signing module. Recent updates on app and extension introduced validation logic that incorrectly rejects valid transaction parameters as malformed, particularly affecting Solana Versioned Transactions and Ethereum EIP-1559 fee structures. The wallet’s internal transaction builder fails to properly serialize instruction data for Solana programs, causing “Transaction fails” errors before the network ever receives the request.

Additionally, the private key extraction from secure enclaves fails intermittently during high-frequency operations, resulting in signature generation errors that the interface displays as generic transaction failures. The RPC load balancer routes transactions to deprecated endpoints that reject modern transaction formats, creating the false impression that the blockchain is rejecting valid operations. For mobile users, background service limitations interrupt the signing process mid-execution, leaving transactions partially constructed and automatically rejected by validation logic.

Solution

Solution 1: Install Phantom Previous Version

Resolution requires deploying the previous Phantom version that maintains stable transaction construction and signing capabilities.

Implementation workflow:

1. Save your Secret Recovery Phrase from Phantom Settings before modifications.
2. Remove the current installation to purge corrupted transaction builders.
3. Install the previous functional version:
   • Extension: Download Phantom Extension v24.5.0 here (transaction execution stable)
   • Mobile: Download Phantom APK v24.5.0 here (signing functional)
4. Restore your wallet from recovery phrase.
5. Verify that transactions construct and broadcast without execution failures. It won’t fail again!

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 Execution Restored

Following deployment of the previous version, transaction execution proceeds reliably with proper serialization and signing. Users can move assets across all supported networks without encountering the pipeline failures that blocked all outgoing operations. The stable architecture ensures that valid transactions reach the blockchain and confirm successfully.
