# Ecosystem Balance ## Introducing the off-chain $DENSITY balance Each wallet has an off-chain ecosystem balance, denominated in $DENSITY, to facilitate gasless transactions within the broader Old Rock ecosystem. The use of an off-chain balance enables us to provide a swift, cost-effective, and seamless experience, especially for competitive gaming. Your Old Rock ecosystem balance is visible in the header of all Old Rock applications and reflects the amount of off-chain $DENSITY you currently have available to use or spend. Earnings from Old Rock apps, such as Amplify or the Airdrop, can add to your balance, while spending $DENSITY can deplete it. ## Deposits and Withdrawals $DENSITY is transferred from your on-chain wallet to your off-chain ecosystem balance through Deposits, which are facilitated by a secure smart contract. The same smart contract also facilitates Withdrawals, i.e., transferring $DENSITY from your off-chain ecosystem balance to your on-chain wallet. * Deposit - Add $DENSITY to your ecosystem balance by depositing from your on-chain wallet that holds the on-chain $DENSITY token. * Withdraw - Move $DENSITY from your ecosystem balance to your on-chain wallet by withdrawing. Once the $DENSITY balance is on-chain, you can swap the token on a DEX for Ethereum and other tokens. Deposit and Withdrawal transactions are on-chain (BASE) transactions and require a signature and a nominal gas fee. ## Platform Fees A 1% platform fee will be collected on every withdrawal. This fee applies to all withdrawn amounts, whether earned or previously deposited. * For example, let’s say you have 1000 $DENSITY in your ecosystem balance. * You had earned 500 $DENSITY in Amplify * You had earned 100 $DENSITY in Shattered World. * You had previously deposited 400 $DENSITY from your wallet. * If you withdraw all 1000 $DENSITY from your ecosystem balance, you will incur a platform fee of 10 $DENSITY (1% of 1000 $DENSITY) and will receive 990 $DENSITY on-chain. Platform fees help defray the costs of operations and fund future ecosystem developments. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
