Double Or Never

Paste transaction
Paste the encoded transaction copied from your wallet.
How it works
Double Or Never reads the transaction before you sign it, finds eligible outgoing token transfers, then lets you choose one to wager. If the reveal hits, the transfer is refunded. If it misses, the wager settles at double the selected transfer. Your connected wallet must be the only required signer.
From your wallet
Start the transaction in Phantom or Solflare.Open the transaction details icon on the wallet prompt.Copy the encoded transaction data, then paste it here.
Replay from Explorer
You can also open an existing transaction in Solana Explorer, download or copy its encoded transaction data, and replay it here with a wager attached. It still only works when your wallet is the sole signer.
