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
