About Transaction Fees
Bitcoin transaction fees are calculated based on the transaction size in virtual bytes (vBytes) and the current network fee rate in satoshis per vByte (sat/vB).
- Native SegWit (bc1...): Most efficient, lowest fees (~68 vB per input)
- SegWit (3...): Wrapped SegWit, moderate fees (~91 vB per input)
- Legacy (1...): Oldest format, highest fees (~148 vB per input)
Fee estimates are based on current network conditions and may vary. Always verify fees before broadcasting a transaction.
