Buy

Spend SOL, USDC or USDT on any Solana coin.

Post

@xfillcash buy 0.5 sol of $BONKPost
@xfillcash buy $20 of <contract>Post
@xfillcash ape 0.1 into $WIFPost
@xfillcash buy 25 usdc of $JUPPost
(as a reply) @xfillcash buy 0.2

Name the coin by $ticker or contract address. Without a coin, a reply buys the coin in the post it answers: its contract, its pump.fun link or its $ticker. A dollar amount is spent in SOL unless you say usdc or usdt.

Sell

Sell a share or all of a coin back to SOL.

Post

@xfillcash sell 50% $WIFPost
@xfillcash sell all <contract>Post
@xfillcash sell half $BONK for usdcPost
(as a reply) @xfillcash dump it

Sell by percentage, "half", "all", a token amount or a dollar amount. Proceeds land in SOL unless you say "for usdc" or "for usdt". A reply can leave the coin out.

Swap

Move between any two tokens.

Post

@xfillcash swap 2 sol to usdcPost
@xfillcash swap 50 usdc into solPost
@xfillcash swap 100% $WIF to solPost

An amount and two tokens, the one you give first. Same route and limits as a buy.

Pay

Send any token to an X handle.

Post

@xfillcash pay @alice 5 usdcPost
@xfillcash tip @bob $3Post
@xfillcash send 0.1 sol to @carolPost

The person gets it in their XFILL wallet and claims it by signing in with X. A dollar amount is paid in USDC. Replying to someone pays them.

Balance

Ask what the wallet holds.

Post
