zeroterm docs
A Solana trading terminal that runs on your own machine and takes no fee. These pages cover installing it, making a first trade, and every setting it has.
zeroterm is a trading terminal you run yourself, in your own terminal or in a browser tab on 127.0.0.1. There is no zeroterm server, no account and no fee account, so nothing in the path of your trade can take a cut.
What it does
- Trades any Solana coin. Coins on pump.fun, Raydium LaunchLab (bonk.fun and others), Meteora DBC (bags.fm and others) and the pools they graduate to trade directly. Every other coin goes through Jupiter's router, which takes no fee either. See Supported coins.
- Keeps your keys at home. Wallet keys sit in an encrypted file on your computer and are unlocked only in the running process. See Keys and security.
- Sends one trade down several routes. The same signed transaction goes to your RPC and to the landing services you turn on, at the same moment. Whichever gets it into a block first wins; the copies cannot fill twice. See Speed and routes.
- Proves every trade. Each trade comes back as a receipt read from the chain: the slot it landed in, how long each route took, and every lamport it cost. See Receipts and positions.
What a trade costs
Take a 0.5 SOL buy of a pump.fun coin at the default speed, fast:
| Cost | SOL | Paid to |
|---|---|---|
| Network fee, one signature | 0.000005 | Solana validators |
| Priority fee | 0.000022 | the validator that includes the trade |
| Landing tip | 0.001 | Helius Sender, which lands it |
| Venue fee | shown on the quote | pump.fun, as on any terminal |
| zeroterm | 0 | nobody |
A hosted terminal charging its 0.95% base fee would take another 0.00475 SOL on the same trade, on top of the same network fees. The priority fee and the tip are yours to set: the eco speed costs 0.0000155 SOL a trade in total.

Not built, on purpose
zeroterm does not do bundled buys across many wallets, launch sniping with wallet farms, or volume bots, and it never holds anyone else's keys.
