SuiSui API Endpoints

unsafe_paySui

Creates an unsigned transaction that sends SUI to multiple recipients. The transaction uses SUI coins for both transfer and gas without requiring a separate gas object. 1. Debits each input coin to create new coins for recipients. 2. Consolidates residual SUI into the first coin, which becomes the gas coin. 3. Updates the first coin balance to: total_input - total_output - gas_cost. 4. Deletes all other input coins.

⚠ This endpoint is only available with Blast access.
