What Is the Polygon Blockchain and Why Does Add2Coin Use It?
When people hear "blockchain" they often think of Bitcoin or Ethereum, with their high transaction fees and slow processing times. Polygon is different. It was designed specifically to solve these problems while remaining fully compatible with the Ethereum ecosystem. This article explains what Polygon is, why Add2Coin uses it, and what this means practically for users of the platform.
What Is a Blockchain?
A blockchain is a database that stores records in a chain of linked groups (called blocks). Once a record is added to the chain, it cannot be altered or deleted without changing every subsequent block — which would require more computing power than the entire network combined. This makes blockchains an extremely reliable way to permanently record transactions, ownership, and any other information that needs to be tamper-proof.
In the context of Add2Coin, the blockchain is used to permanently record who owns how many A2C tokens, and every transfer of tokens between wallets. When the platform mints tokens to reward an ad impression, that minting is recorded on the Polygon blockchain permanently. Anyone can verify how many tokens have been minted, to whom, and when — without needing to trust Add2Coin or any other company.
What Is Polygon?
Polygon is a blockchain network that runs alongside Ethereum but processes transactions much faster and at a fraction of the cost. It uses its own network of validators to confirm transactions, then periodically records summaries of these transactions on the main Ethereum blockchain, inheriting Ethereum's security while achieving far greater efficiency.
The native currency of Polygon is POL (previously called MATIC). Small amounts of POL are used to pay the transaction fees (called gas) on the Polygon network. These fees are typically a fraction of a penny per transaction, compared to fees of several pounds or more on the main Ethereum network.
Why Add2Coin Uses Polygon
The choice of Polygon for Add2Coin was driven by three requirements: cost, speed, and ecosystem compatibility.
Cost is the most important factor. Add2Coin mints tokens to potentially thousands of recipients each day in a single batch transaction. On the main Ethereum network, this transaction might cost tens or hundreds of pounds in gas fees. On Polygon, the same transaction costs pennies. This makes it economically viable to settle small token amounts to many recipients daily, which is essential for the reward system to work at scale.
Speed matters because users expect to see their confirmed token balances update promptly. Polygon processes transactions in seconds rather than the minutes that Ethereum blocks sometimes take. The settlement cron runs at midnight and all pending allocations are confirmed on-chain within minutes.
Ecosystem compatibility means that A2C tokens are standard ERC-20 tokens — the same token standard used by thousands of other cryptocurrency projects. They work with any Ethereum-compatible wallet (MetaMask, Coinbase Wallet, Trust Wallet, and many others), can be traded on decentralised exchanges, and can potentially be bridged to the main Ethereum network in the future as the project grows.
The A2C Smart Contracts on Polygon
The Add2Coin platform uses four smart contracts, all deployed on Polygon Mainnet (Chain ID 137). Smart contracts are self-executing programmes stored on the blockchain that run exactly as written, without the possibility of interference or modification by any party after deployment.
The A2CToken contract at address 0x999ca1479AF9d38933F8EbF7Bb1d2470aFcc337C is the token itself. It enforces the hard supply cap of one billion A2C, manages who has permission to mint new tokens, and handles the batch minting that settles daily reward allocations. The RevenueRouter contract automatically handles the buyback of A2C tokens from the open market using platform advertising revenue. The TreasuryWallet and OperationsKeeper contracts manage long-term reserves and operational expenses respectively.
All four contracts are verified and publicly readable on Polygonscan at polygonscan.com. This means anyone can inspect the contract code, see all transactions, and verify that the platform operates exactly as described in this documentation — without needing to trust anyone at Add2Coin.
How to Set Up a Polygon Wallet
To receive A2C tokens when you withdraw, you need a Polygon-compatible wallet. MetaMask is the most widely used option and works in any web browser as an extension, as well as on iOS and Android as a mobile app.
To use MetaMask with Polygon: install MetaMask from metamask.io, create a new wallet and save your recovery phrase securely (never share this with anyone), then add the Polygon network to MetaMask by visiting chainlist.org and connecting your wallet, then searching for "Polygon" and clicking Add to MetaMask. Once added, your MetaMask wallet can hold POL and any ERC-20 tokens on Polygon, including A2C.
Your Polygon wallet address is a 42-character string starting with 0x. This is what you enter in your Add2Coin account settings as your withdrawal address. Never send A2C to an address on another blockchain — always ensure you are using a Polygon address.
The Uniswap V3 Pool
A2C is tradeable on the open market via a Uniswap V3 liquidity pool on Polygon. Uniswap is a decentralised exchange — a trading platform that operates entirely via smart contracts, with no company or intermediary controlling it. Any person with a Polygon wallet can buy or sell A2C at any time through the Uniswap interface at app.uniswap.org.
The pool was seeded with 136.5 POL and 10,000 A2C, establishing the opening trading price. As the platform grows and more advertising revenue flows through the RevenueRouter to buy A2C from this pool, the pool deepens and trading becomes more liquid. This is how platform growth creates value in the A2C token.
