ConfirmTX is designed as a non-custodial BTC accelerator. The only information required by the form is a public Bitcoin TXID.
Check the domain name and HTTPS before using any Bitcoin accelerator. Impersonation sites may try to collect wallet secrets or payment information.
The free accelerator checks public transaction status and submits valid unconfirmed transaction data through the acceleration route where possible. It does not move coins, sign transactions, or change your wallet balance.
