While your personal Vaulta account is used to send, receive, and stake tokens, a smart contract account can **automate actions**, **manage assets**, or **power an entire app** — all without needing a person to manually approve every action. ## The differences between a user account and smart contract account | Feature | User Account | Smart Contract Account | | ------------------ | ----------------------------------------- | ---------------------------------------------------------------- | | **Purpose** | For individuals to hold and manage tokens | For apps, services, or protocols to run automated actions | | **Controlled By** | A person with private keys | Code (smart contract logic) | | **Actions** | Sending tokens, staking, voting | Runs app functions, swapping tokens, issuing NFTs, holding logic | | **Code Attached?** | No | Yes; executes smart contract functions | ## Who Creates Smart Contract Accounts? Developers or projects deploy smart contracts to a Vaulta account when they want to: * Launch a decentralized application (dApp) * Automate certain blockchain functions * Build tools that others can interact with directly on-chain These accounts are typically **registered with a custom name** (like `vtokenvault`) and appear on block explorers just like any other account. ## Are Smart Contract Accounts Secure? Smart contracts are secure only as long as the **code inside the contract is secure**. That’s why: * Developers test and audit their contracts before launching * Vaulta users should only interact with trusted, verified apps * Transactions on smart contract accounts are **transparent** and viewable by anyone Unlike regular accounts, smart contract accounts don’t need private keys — they respond to **coded instructions** and external triggers. ## How Do I Interact with a Smart Contract Account? Most users interact with smart contract accounts through **dApps or wallets** — you don't need to send a command manually. For example: * When you swap tokens in a Vaulta dApp, you’re sending a transaction to a smart contract account that handles the trade. * When you mint an NFT, a smart contract account creates and stores that digital asset. ## Takeaway A smart contract account is like an app that lives on the blockchain. It holds rules, follows instructions, and runs without needing a person to push buttons. You use them every time you use a dApp — even if you don’t see them. ## Resources # EVM Accounts # Spring # System Contracts Vaulta system contracts are a collection of contracts specifically designed for the Vaulta blockchain. # Vaulta EVM Framework # Trustless Bridge # Block Producers Block Producers (BPs) are the core infrastructure providers of the Vaulta blockchain. They are responsible for validating transactions, producing blocks, maintaining network performance, and participating in on-chain governance. Vaulta uses a Delegated Proof-of-Stake (DPoS) consensus mechanism, which means block production and governance are delegated to elected entities—known as Block Producers—by Vaulta token holders. ## Key Responsibilities of Block Producers * **Produce Blocks**:\ BPs take turns generating blocks every 0.5 seconds in a round-robin fashion. There are 21 active BPs at any given time. * **Validate Transactions**:\ BPs confirm and record transactions into the blockchain, ensuring accuracy and finality. * **Maintain Infrastructure**:\ Each BP must run high-performance servers and maintain uptime and reliability standards to keep the network running smoothly. * **Participate in Governance**:\ BPs vote on system contract changes, network upgrades, funding proposals, and other governance activities. * **Support the Ecosystem**:\ Many BPs contribute to the Vaulta ecosystem by developing tools, educating users, funding community initiatives, or maintaining public services like block explorers or APIs.| Term | Definition |

| Smart contract | Smart contracts are programs designed and stored on a blockchain that run when predetermined conditions are met. Smart contracts are used to automate the execution of an agreement between buyer and seller. They can also automate a workflow, triggering the next action when conditions are met. A smart contract enables the code to run independently, with no third-party operators. For example, when placing an order on a decentralized exchange, the crypto you intend to buy/sell goes into a smart contract. The party on the other side of the trade also puts their crypto in the smart contract. When the prices match, the smart contract sends the funds to the appropriate parties based on their order. |
| Staking | Staking is when a token holder locks up portion of their token for a period of time. A token holder contributes to a network by staking their tokens and in exchange earns rewards. Typically token holders earns rewards in a form of tokens after they stake their tokens. DAPPs use the concept of staking to give rewards and other non-financial benefits such as voting to their users. When you unstake, you lose voting power, but your tokens become liquid. |
