onestop runs on your own machine — the client starts it, so there is no endpoint to ping. 386 installs a week from npm. Last commit 3 Nov 2026.
Gasless Solana swaps, market-cap limit, trailing and TWAP orders, and plans. Your key stays local.
Nothing serious here today
Today is the operative word: we check onestop every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

<ONESTOP_PRIVATE_KEY> (The private key of the wallet that trades, as your wallet exports it. Use a wallet you keep for trading).
The author’s registry entry marks it as required.
Optional settings from the registry entry, left out of the block above:
ONESTOP_KEYPAIR_PATH (Or the path to a keypair file, instead of the private key), SOLANA_RPC_URL (Your RPC, used to simulate every transaction before signing (default: public mainnet)), ONESTOP_DRY_RUN (true to trade nothing: order tools answer without calling onestop and swaps stop after the guard).
