Unconfirmed
Sent the payment? Check whether your wallet supports increasing its fee with RBF. The wallet creates a replacement transaction, so the transaction ID may change.
Receiving the payment? A wallet that supports CPFP may let you spend an output you control with a higher fee. This helps the parent and child together only if miners can include the package.
Compare your fee rate with current mempool fees. Confirmation time depends on demand, miner policy and any unconfirmed parent transactions. Fees →
How it works
Checks Bitcoin mainnet transactions through mempool.space. Only the public transaction ID is needed. Fee rate uses fee ÷ virtual size, rounded up from weight ÷ 4. Results refresh every 30 seconds for up to 15 minutes while this page is open.
