🫶 ARGUMENTS 🫶

• tx_ring — the tx ring you're setting up. this is the thing getting the glow-up, bestie 💖

🔥 DESCRIPTION 🔥

so what does it actually return? literally just this:

• returns 0 on success (slay ✨)
• returns a negative value on error (and that's the whole error report, don't come for me, that's what the page says 😭)
