# Security — non-custodial, atomic swaps on Argyros

> Security model of the Argyros aggregator on Fogo.

## Non-custodial

Argyros never holds or has access to your funds. The API returns unsigned transactions. Your wallet signs and submits them directly to the Fogo network.

## Atomic execution

All swap instructions execute atomically on-chain. If any hop in a multi-hop route fails (insufficient liquidity, slippage exceeded, etc.), the entire transaction reverts. No partial fills.

## Slippage protection

Every swap includes a slippage threshold (`slippageBps`, measured in basis points where 1 bps = 0.01%). The on-chain program enforces this. If the execution price deviates beyond the threshold, the transaction fails.

## Open-source verification

The on-chain program is verifiable. Integrators can inspect the instructions returned by the API to confirm exactly what will execute before signing.
