Anyone can issue a token called ASTEROID on the XRP Ledger, and ASTEROID tokens exist on other networks entirely. The ticker alone identifies nothing.

The pair that matters

ASTEROID XRPL is the currency ASTEROID issued by rS5LWaqWuzmoiNpzgYJbPvD1bsRZTgDG7 on XRPL Mainnet, with the currency hex 41535445524F4944000000000000000000000000. Both values are copyable across this site.

Before you set a trustline

Paste the issuer address into an XRPL explorer and confirm it matches what you see here. Check the token page and the AMM pair. If a link, a bot or a DM gives you a different issuer, it is a different token.

And the obvious

ASTEROID is a highly speculative community token. Nothing here is financial advice and you can lose everything you put in.
