Frequently Asked Questions

Is OpenSwap safe to use?

OpenSwap is noncustodial and open source (MIT). It never asks for a seed phrase or private key — it mints a deposit address for the route you choose, and you pay from any wallet you already trust.

What does it cost?

$0 upfront — no integration or setup cost. You only pay when a swap executes: 0.10% of the swap (10 basis points), the industry floor. Founding keys drop that to 0.01% for life, and stablecoin-to-stablecoin pairs are 0.01% for everyone.

Which chains and tokens are supported?

30+ blockchains and 20,000+ tokens, including BTC, ETH, SOL, and most major L1s and L2s, aggregated live across THORChain, Chainflip, Maya, NEAR Intents, Relay, Rango, and more.

Do I need an account or API key?

No. npx openswap@latest works immediately on a built-in community key at the standard 0.10% rate. A founding key is a limited-seat optional upgrade — one of only 100 — that drops the fee to 0.01% for life.

Can AI agents and trading bots use it?

Yes — bots and agents are first-class users. Every command can output clean machine-readable data, every swap leaves a saved receipt an agent can pick back up, the package ships with instructions AI agents understand out of the box, and test mode gives bots a full practice exchange before real money is involved. There is also an MCP server at leokit.dev/mcp for conversational AI.
