- Paste addresses to check balances (confirmed and pending shown apart)
- Convert between BTC and sats
FAQ
- Why no sending?
- The reference site is read-only on BTC too. Bitcoin is UTXO-based, so batch sends need full coin selection and PSBT signing, quite unlike the other chains here.
- Which address formats work?
- Lookups accept every common format (1 / 3 / bc1). The generator produces bc1 segwit addresses by default and can switch to legacy.
