Why Selecting the Correct Wallet Type Matters When Sending or Receiving Funds Through CMPFX
🔹 What Are SegWit and Legacy Wallets?
When sending or receiving Bitcoin payments through CMPFX, you may notice two common wallet address types: SegWit and Legacy.
Each type has different formats, fees, and compatibility levels — which makes it very important to choose the correct one before transferring funds.
Legacy Wallet (P2PKH)
Address Format: Starts with the number “1” (e.g.,
1Lx9…).Network Type: Original Bitcoin address format.
Compatibility: Supported by all exchanges and wallets.
Fees: Typically higher due to older transaction structure.
Speed: Slightly slower, as transactions take up more data in each block.
SegWit Wallet (P2SH or Bech32)
Address Format:
P2SH (Compatible SegWit): Starts with “3” (e.g.,
3J98…).Native SegWit (Bech32): Starts with “bc1” (e.g.,
bc1q…).
Network Type: Upgraded Bitcoin format designed to reduce transaction size.
Compatibility: Supported by most modern exchanges and wallets.
Fees: Lower, since SegWit transactions are more data-efficient.
Speed: Slightly faster confirmation times and improved scalability.
🔹 Why the Correct Wallet Type Matters
When funding your CMPFX account, it’s crucial that the sending wallet type matches or supports the wallet type you select in CMPFX.
Using the wrong type can cause:
Failed or missing deposits if your sending wallet doesn’t support the address type.
Delays in confirming transactions on the blockchain.
Higher network fees than necessary if you select a legacy wallet unnecessarily.
🔹 CMPFX Wallet Selection Best Practices
When you go to deposit funds into your CMPFX account:
Check your sending wallet type.
Open your crypto wallet or exchange and identify whether it uses a Legacy (1...), P2SH (3...), or Bech32 (bc1...) format.
Match the type in CMPFX.
If your sending wallet starts with 1, choose a Legacy wallet option.
If it starts with 3 or bc1, choose a SegWit wallet option.
Confirm before sending.
Always double-check that the address you copied from CMPFX matches the correct format before confirming the transaction.
If you are unsure which type your current sending wallet or exchange uses, reach out to their support team.
🔹 Key Takeaways
Legacy = older, universally compatible, but higher fees.
SegWit = modern, faster, cheaper transactions.
Always match address types between your CMPFX wallet and your sending wallet to ensure smooth and secure transfers.
⚠️ Important Reminder
CMPFX cannot recover funds sent to incorrect wallet types or incompatible addresses. Always verify the wallet format and network before confirming any deposit.
