# Pre-fund Pre-funding is the simplest way of sponsoring transactions. It works on all chains with every type of address. When sponsoring a transaction, Blink will simply fund the fee paying address with enough native currency so that the transaction can be included. Advantages: * Works on all chains * No setup required. Just send us your eth\_sendRawTransaction (EVM) / sendTransaction (Solana). We'll sponsor the transaction if it's balance is not high enough to land. Disadvantages * Slightly less efficient * Can leave a "dust" balance on the user's wallet --- # 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.
