Non-SegWit wallets, also known as Legacy wallets, use the original Bitcoin address format, which starts with the number '1'.
These addresses are compatible with all Bitcoin wallets, but they do not utilize the optimizations that SegWit offers.

SegWit wallets utilize a newer address format that starts with '3' for P2SH (Pay-to-Script-Hash) and 'bc1' for native SegWit addresses.
This more advanced format allows for greater efficiency in transaction processing.
SegWit stands for Segregated Witness, a protocol upgrade that separates signature data from transaction data.
This separation allows more transactions to fit into a single block, addressing Bitcoin's scalability issue.
The implementation of SegWit is a soft fork, meaning it is backwards compatible.
This allows users with non-SegWit wallets to still interact with SegWit wallets, facilitating a smooth transition without disrupting the network.
Transactions from a SegWit wallet to a non-SegWit wallet can be conducted seamlessly, but they may incur higher fees due to the larger block size taken up by the traditional format.
SegWit helps reduce the size of Bitcoin transactions, which can lower transaction fees.
This efficiency is particularly beneficial during peak network congestion when fees tend to rise.
The introduction of SegWit has led to the creation of the Bech32 address format.
Bech32 addresses are more user-friendly due to their lower case-only character set, reducing the chance of errors when entering addresses.
SegWit adoption has been a significant factor in increasing the overall capacity of the Bitcoin network, allowing for more transactions per second without increasing block size limits.
Non-SegWit wallets may not support advanced features such as transaction batching or CoinJoin, which are often utilized by SegWit wallets to enhance privacy and reduce fees further.
The average transaction confirmation time in a SegWit wallet can be faster due to the reduced weight of transactions, enabling miners to prioritize them more effectively during periods of high demand.
SegWit also provides a mechanism for future upgrades to the Bitcoin protocol without requiring hard forks, making it easier to implement new features and improvements.
Legacy addresses are still widely used, particularly by users who have not yet migrated to SegWit.
This continued use can lead to fragmented transaction paths, complicating the user experience in some instances.
Users of non-SegWit wallets may face limitations in accessing certain decentralized applications (dApps) or features that are optimized for SegWit usage.
The adoption rate of SegWit continues to grow; as of early 2025, around 80-85% of Bitcoin transactions are processed through SegWit addresses, reflecting a significant shift in user preference.
SegWit transactions can be more complex to analyze on the blockchain due to the separation of witness data, which can impact forensic analysis and tracking of Bitcoin movements.
Wallets that support both SegWit and non-SegWit can provide users with flexibility, allowing them to choose which address type to use based on their needs or preferences.
The introduction of SegWit has paved the way for Layer 2 solutions like the Lightning Network, which relies on SegWit’s features to facilitate instant transactions and micropayments.
While SegWit addresses are more efficient in terms of block space usage, not all wallets provide full support for all SegWit features, leading to potential compatibility issues.
Certain exchanges may only provide non-SegWit addresses for withdrawals, limiting users who want to take advantage of SegWit benefits when moving their funds.
Understanding the differences between SegWit and non-SegWit wallets is crucial for anyone involved in Bitcoin transactions, as it can significantly affect transaction costs, speed, and overall user experience.
