What is decentralized finance?#

Decentralized finance, or DeFi, is financial activity carried out through blockchain accounts and smart contracts rather than a traditional intermediary holding every user's assets. CenturionDEX is a DeFi interface for interacting with the Centurion Protocol on the Centurion blockchain.

How it works#

Smart contracts define rules for actions such as swapping tokens, providing liquidity, borrowing, or issuing assets. Users authorize transactions from their own wallets, and the network executes the code on shared state.

DeFi is often described as permissionless because anyone can deploy a contract or create a token. That openness also means there may be no team screening assets, reversing transactions, or guaranteeing that a contract is safe.

On CenturionDEX:

v2 pools use x · y = k, full-range liquidity, a 0.30% fee, and CRC-20 LP tokens.
v3 pools use concentrated liquidity, ticks, selectable fee tiers, and CRC-721 position NFTs.
CTN pays network costs measured in Newtons.
WCTN represents native CTN inside pools.

Self-custody and authorization#

A self-custodial wallet lets you control transaction authorization. Connecting a wallet exposes your public address to the interface; signing gives specific authority according to the message or transaction.

That authority can be broader than it looks. Token allowances, NFT operator approvals, smart-account modules, and batched calls can remain effective after a site is disconnected. Read the wallet details and periodically review permissions.

Why people use DeFi#

Users may want transparent onchain rules, direct market access, programmable assets, or the ability to provide liquidity. Developers can compose contracts with existing standards on the EVM-compatible CVM.

These benefits do not remove risk. Common risks include:

Smart-contract bugs or privileged administrator controls.
Volatile prices and thin liquidity.
Impermanent loss for liquidity providers.
Malicious or restricted tokens.
Oracle, bridge, wallet, or interface failures.
Phishing and deceptive signatures.
Irreversible sends and transactions.

A practical safety process#

Verify the network, contract addresses, and official interface.
Understand what the contract will do before signing.
Start with a small amount.
Keep native CTN for network costs.
Limit approvals and remove unused permissions.
Use separate accounts or hardware signing for higher-value activity.
Treat promised returns, giveaways, and urgent support messages as warning signs.

Stay safe#

No legitimate DeFi support process requires your recovery phrase, private key, or password. Smart contracts execute exactly according to their code and current state; a professional-looking interface does not guarantee safe contracts or tokens.
