On Solana · nothing to sign up for

Every X handle already has a cubby.

Drop SOL or tokens into anyone's cubby with nothing but their @. We hold it until they sign in with X and take it. They don't need a wallet yet, just an X account.

Try or your own. Every handle's cubby exists before anyone opens it.

How it works

Drop. Wait. Grab.

  1. Drop

    Every X handle has its own Solana wallet address, ready before anyone opens it. Send from this page, from any wallet, or paste it wherever a payout address goes.

  2. Wait

    We keep the keys. The money only leaves when the handle's owner signs in with X, and every balance is public on chain, so anyone can check what's waiting.

  3. Grab

    The owner signs in with X, names any Solana wallet, and we send everything over. We pay the network fee, so they don't need SOL to claim.

Recent drops

Drops made on this page and every claim show up here. A drop sent from another wallet still lands in the cubby; open the cubby to see it.

Is one of these yours?

Sign in with X to open your cubby.

X tells us your handle and nothing else. We give the X token back right after, and keep a four-hour cookie that says which handle you are.

Questions people ask

Who holds the money?

We do. Cubby is custodial: every cubby is a real Solana wallet whose key only our server can derive. We sign a transfer out only after the handle's owner signs in with X, and every balance is public on chain, so you can always see what's waiting.

What if they never claim it?

It stays in their cubby. There are no refunds: once something is dropped, it belongs to whoever holds that handle.

Can I import the cubby address into a wallet?

No. Its key never leaves our server. The only way out is signing in with X and claiming.

What happens when someone changes their handle?

A cubby belongs to the handle, not the person. Whoever holds the handle when they sign in can claim it. If you rename, claim first.

Which tokens work?

SOL and any SPL or Token-2022 token. The page offers SOL and USDC for dropping and shows every token a cubby holds. Each one can be claimed.

Why is there a minimum on the first drop?

Solana won't let an empty wallet hold less than its rent floor, about 0.00089 SOL. After the first drop, any amount works. The first drop of a token also pays about 0.002 SOL to open the cubby's account for it.

Does claiming cost anything?

No. We pay the network fee. You get everything that's in the cubby.

Does this have anything to do with X?

No. It uses X only for "Sign in with X" and isn't affiliated with or endorsed by X Corp.
