Execution Layer

Introduction

The Staco Chain Execution Layer is responsible for processing transactions, executing smart contracts, and maintaining the state of the blockchain. As a fully Staco Virtual Machine (SVM) Layer 1 blockchain, Staco Chain follows the same execution model as Ethereum, ensuring compatibility with existing Ethereum-based tools and applications.

Overview of the Execution Layer

  • The Execution Layer is a crucial component of Staco Chain, responsible for handling:
  • Transaction Processing – Validating and executing user transactions.
  • Smart Contract Execution – Running decentralized applications (dApps) and executing Solidity-based smart contracts.
  • State Management – Updating account balances, contract storage, and network state after transaction execution.
  • EVM Compatibility – Ensuring seamless interaction with Ethereum-based wallets, tools, and protocols.

Core Components of the Execution Layer

  • Staco Virtual Machine (DVM) Executes smart contracts and processes transactions within the Staco Chain network. Fully compatible with Solidity, Vyper, and other Ethereum-based development languages.
  • Transactions & Gas Fees Transactions require gas fees, similar to Ethereum, to prevent spam and allocate network resources efficiently. Gas fees are paid in the native token of Staco Chain.
  • Smart Contract Execution Developers can deploy and interact with smart contracts using Ethereum-standard tools like Remix, Hardhat, Truffle, and Web3.js. Supports ERC-20, ERC-721, and other Ethereum token standards.
  • State Management The Execution Layer updates the blockchain state by processing transactions and storing contract states. Utilizes Merkle Patricia Tries for efficient storage and retrieval of account data.
  • Interoperability Staco Chain’s Execution Layer is designed for seamless integration with existing Ethereum infrastructure. Supports Ethereum’s JSON-RPC API, allowing easy interaction with wallets like Metamask, Trust Wallet, and other.

How the Execution Layer Works

  • Transaction Submission – Users submit transactions through wallets or dApps.
  • Transaction Validation – Transactions are verified by the network’s nodes.
  • Execution in the EVM – The smart contract code is executed within the EVM environment.
  • State Update – The blockchain state is updated based on the execution results.
  • Block Finalization – Valid transactions are added to new blocks and propagated across the network.

Developer Tools & Integration

To build on Staco Chain, developers can use:

  • Solidity & Vyper for smart contract development.
  • Truffle & Hardhat for contract deployment and testing.
  • Web3.js & Ethers.js for blockchain interactions.
  • Metamask & WalletConnect for user authentication and transactions.
