PRC20: The Standard for PowBlocks Tokens.

PRC20: The Standard for PowBlocks Tokens

As the blockchain space evolved, standards became vital for interoperability, consistency, and ease of integration. Ethereum gave us the ERC20 standard, which quickly became the benchmark for token implementations. PowBlocks, in its pursuit of excellence and compatibility, introduced its own version: the PRC20.

1. What is PRC20?

PRC20 is a token standard on the PowBlocks blockchain. It defines a set of rules that a token contract must implement to ensure consistent interaction across various platforms, DApps, and interfaces. This standard ensures that different tokenized assets on PowBlocks can be handled similarly, eliminating the complexities of dealing with diverse custom token functionalities.

2. Key Features of PRC20 Tokens:

Uniformity: All PRC20 tokens follow the same set of rules. This means they have the same methods and properties, ensuring uniformity across all token contracts on the PowBlocks blockchain.

Interoperability: Due to their standardized nature, PRC20 tokens can be easily integrated with existing applications, wallets, exchanges, and other services with minimal adjustments.

Simplicity: Developers familiar with Ethereum's ERC20 will find it straightforward to work with PRC20. The standards share many similarities, making the transition or parallel development on PowBlocks more accessible.

3. Essential Functions of PRC20:

The PRC20 standard encompasses several functions, including but not limited to:

totalSupply(): Returns the total token supply.

balanceOf(address _owner): Returns the token balance of a specific address.

transfer(address _to, uint256 _value): Transfers a specific token amount to a given address.

transferFrom(address _from, address _to, uint256 _value): Allows for token transfers on behalf of a user, given that they've provided approval.

approve(address _spender, uint256 _value): Approves a third-party, like a DApp, to transfer tokens up to a specified amount.

allowance(address _owner, address _spender): Returns the amount of tokens a spender is allowed to transfer on behalf of an owner.

4. Events in PRC20:

For frontend applications and DApps to interact and react to changes, PRC20 tokens emit events, such as:

Transfer(address indexed _from, address indexed _to, uint256 _value): Emitted when tokens are transferred.

Approval(address indexed _owner, address indexed _spender, uint256 _value): Emitted when approval is granted to spend tokens on behalf of an owner.

5. Compatibility with EVM:

Given that PowBlocks supports the Ethereum Virtual Machine (EVM), the PRC20 standard is designed to be familiar to developers from the Ethereum ecosystem. This ensures that porting applications between the two blockchains remains streamlined.

In essence, the PRC20 standard is a testament to PowBlocks' commitment to a seamless and developer-friendly environment. Whether you're looking to mint a new token, integrate with an existing one, or develop sophisticated DApps, the PRC20 offers a reliable foundation for your endeavors on the PowBlocks blockchain.

How to Deploy Contracts on PowBlocks using Remix IDE

Deploying contracts on PowBlocks is a seamless experience, especially if you're familiar with the Ethereum ecosystem. Given the compatibility of PowBlocks with the Ethereum Virtual Machine (EVM), any Ethereum-based Integrated Development Environment (IDE) can be employed for this purpose. In this guide, we'll focus on using Remix IDE, a popular open-source tool for developing smart contracts.


A PowBlocks wallet with enough balance for deployment fees.

Remix IDE (accessible via browser at )

Steps to Deploy Contracts on PowBlocks:

Access Remix IDE: Navigate to  using your preferred web browser.

Create or Import Your Smart Contract:

Click on the '+' icon to create a new contract.

Alternatively, you can import an existing contract by dragging and dropping the contract file into Remix or using the file explorer in Remix.

Select the Correct Compiler:

On the left sidebar, click on the "Solidity" icon.

Choose an appropriate compiler version that matches your contract's pragma statement.

Click on "Compile .sol" to compile your smart contract.

Switch to PowBlocks Environment:

On the left sidebar, click on the "Deploy & Run" icon.

From the "Environment" dropdown, you'd typically choose "Injected Web3" if using a browser extension like MetaMask. Ensure that your wallet or browser extension is configured to connect to the PowBlocks network.

Deploy Your Contract:

Select the compiled contract from the dropdown list.

If your contract has constructor parameters, fill them in.

Click on the "Deploy" button. A confirmation will pop up from your wallet or browser extension. Confirm the transaction.

Once confirmed, the contract will be deployed to the PowBlocks network, and you'll see your contract address and other details in the "Deployed Contracts" section of Remix.

Interact with Your Contract:

In the "Deployed Contracts" section, you'll find various functions related to your contract. You can now interact with these functions directly from Remix.


Always ensure that your wallet or browser extension is set up correctly to connect to the PowBlocks network. Deploying and interacting with smart contracts incurs transaction fees, so ensure your PowBlocks wallet has a sufficient balance.

By following the steps above, you can efficiently deploy and manage smart contracts on PowBlocks using Remix IDE or any other Ethereum-based IDE of your preference. Happy coding!
