You can launch command-line tools from your Octane server directory. You can learn how to set it up in SETUP.
yarn run cli generate-config-with-popular-tokens
Generates JSON to put in config.json
as token fees for a specific endpoint. It loads popular tokens from Jupiter aggregator, calculates fees according to arguments and selects accounts to receive fees.
Config should be generated for each endpoint separately — in most cases, with different arguments.
Endpoints like transfer
and buildWhirlpoolSwap
require less SOL, so margins could be higher. Endpoint createAssociatedTokenAccount
, that charges fee payer for a rent exemption payment on a new token account, must include --include-account-fees
and may use lower margins, since the original price would be much higher.

Argument | Description | Default value |
---|---|---|
-t, --tokens-from-top | Tokens from the top of Jupiter aggregator to include | 10 |
-m, --margin | Part of total user-paid fee that fee payers take as a surplus to transaction costs. From 0 to 1. For example, 0.5 would mean that user pays 2x the SOL signature fee. | 0.9 |
-a, --include-account-fees | Includes cost creating an associated token account in each fee pre-margin. Use this flag when filling out the endpoints.createAssociatedAccount part of config. |
yarn run cli generate-config-entry
Generates a config entry for a single provided token. All rules of generate-config-with-popular-tokens
apply here as well.
Argument | Description | Default value |
---|---|---|
-m, --margin | Part of total user-paid fee that fee payers take as a surplus to transaction costs. From 0 to 1. For example, 0.5 would mean that user pays 2x the SOL signature fee. | 0.9 |
-a, --include-account-fees | Includes cost creating an associated token account in each fee pre-margin. Use this flag when filling out the endpoints.createAssociatedAccount part of config. |
yarn run cli swap-tokens-to-sol
Swaps tokens on accounts in config.json
to SOL using Jupiter aggregator HTTP API.
It's recommended to run this command automatically every few hours to make sure fee payer always has enough SOL.
Argument | Description | Default value |
---|---|---|
-d, --dry-run | Do not execute swaps, just calculate routes | |
-t, --threshold | Minimum value of tokens to exchange, in SOL lamports | 100000000 |
yarn run cli create-accounts
Creates associated token accounts for tokens specified in config.json
. Octane will need these accounts to receive fee payments
from users.
Argument | Description | Default value |
---|---|---|
-d, --dry-run | Do not create accounts, just output what should be created |
