A Wild Rift login is a Riot login, and it may open League, Valorant and Teamfight Tactics on the same account. That raises the stakes of a handover, and most of what goes wrong in private sales is solved structurally here. The rest is on the seller to get right.
Only list accounts you own
Flipping an account a boosting or coaching client handed you access to breaks the terms, and it closes every EB24 track to you at once.
Hand over the whole Riot account
Whether the sale sticks comes down to email control. Unlink your own recovery details before delivery, and remember the buyer receives everything tied to that Riot login, not the mobile client alone.
Keep it on-platform
Take the deal off EB24 and both the payment guarantee and the dispute process disappear, and those two things are why a stranger paid you at all.
Deliver fast
Buyer reviews mostly measure how fast you delivered, and a review trail is what turns the tenth sale into an easier one than the first.
If you also play at a high level, the accounts you sell are not the only thing you can earn from here. The Wild Rift booster track and the Wild Rift coach track pay into the same EB24 balance, and sellers with PC stock list it through the LoL account seller page.
