Overview
- SegWit Addresses (P2SH): Reduce transaction data size, speeding up transactions, improving scalability, and lowering fees.
- Native SegWit (Bech32): Further optimizes efficiency, offering even lower fees and enhanced error detection.
- Compatibility: Not all exchanges/wallets support sending Bitcoin to Native SegWit addresses (
bc1), so Ledger Live provides both options. - Interoperability: Transactions between Legacy (
1), SegWit (3), and Native SegWit (bc1) addresses are fully compatible.
Understanding SegWit Addresses
Introduced in August 2017 via a soft fork, Segregated Witness (SegWit) addresses revolutionized Bitcoin transactions by:
- Reducing Data Size: Separating signature data from transaction details to shrink each transaction’s footprint.
- Boosting Scalability: Enabling more transactions per block, faster processing, and lower fees.
- Enabling Lightning Network: Paving the way for Layer 2 solutions like Bitcoin’s Lightning Network.

Native SegWit (Bech32): The Next Evolution
Native SegWit (bc1 prefixes) builds on SegWit’s advantages with:
- Higher Efficiency: Smaller transactions than SegWit, further reducing fees.
- Robust Error Detection: Bech32’s checksum minimizes typos and lost funds.
- Readability: Lowercase letters simplify address sharing.
Limitation: Some platforms still don’t support sending BTC to bc1 addresses.
Choosing Between SegWit and Native SegWit
| Factor | SegWit (3) | Native SegWit (bc1) |
|----------------------|-------------|-----------------------|
| Transaction Fees | Lower | Lowest |
| Adoption | Widespread | Growing (check compatibility) |
| Error Handling | Standard | Advanced |
Opt for Native SegWit where supported, or use SegWit for broader compatibility.
FAQs
1. Can I send Bitcoin from a Legacy address to a Native SegWit address?
Yes! All address types (Legacy, SegWit, Native SegWit) are interoperable.
2. Why doesn’t every platform support Native SegWit?
Bech32 adoption requires backend updates; some services prioritize older formats.
3. Which address type is cheapest for transactions?
Native SegWit (bc1) offers the lowest fees due to maximal data compression.
