Keys, fees & founding keys

What does OpenSwap cost?

The tool itself is free and open source. When a swap actually executes, two kinds of cost apply:

Route fees — network and protocol fees set by whoever executes the

swap (Chainflip, THORChain, Maya, NEAR, Relay, and the rest). Every quote shows these before you commit, and if a provider doesn't price one, the CLI says not priced rather than pretending it's zero.

The platform fee — 0.10% of the swap on the built-in community key.

Stablecoin-to-stablecoin swaps are cheaper for everyone: 0.01%.

There are no subscriptions, no gas markups, and nothing hidden. Every route shows its full cost up front.

The built-in community key

npx openswap@latest works out of the box because a shared, intentionally public community key ships inside the tool. It can fetch quotes and prepare swaps — and nothing else. It can't move funds and can't see anything private. Affiliate fees on community-key volume go to LeoDex, which is what pays for the free tier.

Get your own key (and keep the affiliate fees)

Here's the honest economics: every swap routes an affiliate fee to whoever's API key was used. On the community key, that's LeoDex. **With your own key, it's you.** If you're building a bot, an app, or just routing your own serious volume, that fee belongs in your pocket.

Keys are free at dash.leokit.dev — sign in with Google or GitHub, no sales call. Then store it securely:

openswap auth login

The key goes into your operating system's keychain, not a file. For CI and bots, use the OPENSWAP_API_KEY environment variable instead.

Founding keys: 0.01% for life

The first 100 people to claim a founding key swap at a **0.01% platform fee forever** — one tenth of the standard rate, on everything, permanently.

Claim yours at leokit.dev/cli. It takes an email address; the key appears on screen immediately. One key per email — and if you ever lose it, submit the same email again and your key is shown again. When the hundred are gone, they're gone.

Fork it — seriously

OpenSwap is MIT licensed, and forks are welcomed on purpose: put your own API key in a fork and the affiliate fees on all its volume are yours. That's the deal — the platform fee funds the rails either way, and the affiliate layer rewards whoever brings the users. The repo includes a brand pipeline (one JSON file regenerates every logo and banner), so a rebranded fork is an afternoon's work, not a design project. Two asks: keep the MIT notice, and never commit a raw webhook or key to your fork.
