SOL

Gasless Transactions on Solana

This section of the whitepaper outlines our approach to facilitating seamless and cost-effective transactions on the Solana blockchain without requiring users to expend SOL for transaction fees. Utilizing a subsidy model, our wallet covers the transaction fees on behalf of the user, ensuring a smooth and accessible user experience.

Implementation Overview:

  • User Transaction Initiation: Users initiate transactions by simply entering the recipient’s address. There is no need for the user to possess SOL specifically for covering gas fees, as the transaction fee is subsidized by the wallet.

  • Subsidy Mechanism: When a transaction is initiated, the required SOL for the transaction fee is temporarily fronted by the wallet. This subsidy is drawn from a pool of SOL specifically allocated for this purpose, ensuring that transactions are processed quickly and efficiently on the Solana network.

  • Anti-Sybil Firewall: To safeguard against exploitation of the subsidy mechanism by malicious actors, Sharks Wallet employs a sophisticated Anti-Sybil Firewall. This system effectively prevents dishonest users from draining the subsidized resources through fraudulent activities or manipulation. The firewall monitors transaction patterns and flags unusual behaviors, ensuring that only legitimate transactions are subsidized.

  • Step-by-Step Subsidization: The process of subsidizing transaction fees is conducted in a controlled, step-by-step manner. Each transaction is individually assessed, and the necessary SOL is allocated to cover the transaction fee. This methodical approach ensures optimal use of resources and maintains the integrity of the subsidy pool.

  • Final Transaction Execution: After the transaction is confirmed and the SOL fee is subsidized, the smart contract processes the transaction and forwards the funds to the recipient’s address. The transaction completes without any SOL expenditure from the user’s side, enhancing the user-friendly nature of the platform.

This gasless transaction framework on Solana represents a pivotal advancement in making blockchain technology more accessible and cost-effective. By subsidizing the transaction fees, Sharks Wallet encourages broader adoption of Solana-based applications and services, while ensuring the sustainability and security of the subsidy mechanism through robust anti-fraud measures.
