What is a crypto wallet?#
A crypto wallet is software or hardware that manages the authority needed to use a blockchain account. It does not hold coins like a physical wallet; your CTN and tokens are recorded on Centurion, while the wallet signs instructions that change those records.
How it works#
A traditional account uses a private key to create digital signatures. The network verifies the signature before accepting a transaction. A recovery phrase may derive one or more private keys, so anyone who obtains it can usually control every related account.
A smart-account wallet uses contract code to define authorization. It may support multiple signers, recovery guardians, spending limits, session permissions, or batched actions. These features can improve safety and usability, but you must still understand what each signer, module, or session key can do.
The wallet also provides an interface for:
- Selecting a blockchain such as Centurion mainnet.
- Displaying native CTN and recognized tokens.
- Connecting an address to CenturionDEX.
- Showing transaction simulations and requested permissions.
- Broadcasting signed transactions to the network.
What happens when you connect#
Connecting normally lets a site see your public address and request signatures. It does not automatically give the site custody of your assets. Risk begins when you approve a token, authorize an NFT operator, sign a message with unintended meaning, or submit a transaction.
Disconnecting removes the site's browser connection but does not cancel onchain approvals or smart-account permissions. Those must be reviewed and removed separately.
Worked example#
When swapping a CRC-20 token for CTN, your wallet may show two actions. The first grants the Centurion Protocol contract permission to spend the selected token amount. The second executes the swap. A smart-account wallet may present both in one batch, but each underlying action still matters.
The wallet also estimates the CTN needed for Newtons. WCTN in a pool cannot pay that network cost; you need native CTN in the account.
Common issues#
- Wrong network: the interface and wallet must both show Centurion.
- Missing token: import the verified token contract for display.
- Insufficient funds for fees: keep native CTN available.
- Pending transaction: check its status before submitting replacements.
- Unexpected signature: cancel and verify the site and requested authority.
Stay safe#
Use separate accounts for long-term holdings and routine application activity when practical. Keep recovery material offline, review permissions, and consider hardware signing for significant value. Never share a recovery phrase, private key, password, or one-time code with support.
