How a swap works

POST /api/swap  →  deposit address issued
                      ↓   (you send funds there)
              deposit detected  →  rate locked
                      ↓
              vault lock / gather  →  payout executed

Each swap gets its own deposit address. You send the source asset to that address and the bridge handles everything after — detection, rate locking, gathering into the vault, and the payout on the target chain.

Send only the asset the swap expects

A deposit address belongs to one swap, for one asset, on one chain. Sending something else, or sending after the window expires, is not automatically recoverable.

Components

Component	Responsibility
Routing engine	Chooses the route for a requested pair
Wallet service and key manager	Derives deposit wallets; keys encrypted at rest
Blockchain monitor	Polls deposit addresses for incoming transfers, every 20 seconds
Rate engine	Prices the swap and locks the rate
Vault manager and gather service	Locks source funds and gathers them
Payout executor	Sends the target asset
Webhook dispatcher	Records and delivers lifecycle events

Routes include direct liquidity-pool swaps, vault-backed routes, internal multi-hop routes, and routes that use SimpleSwap as an external leg.

Fees

The bridge fee is returned by the API rather than fixed in documentation:

curl -s https://bridge.testnet.kriptonyx.com/api/swap/config

Observed completed swaps carried a 2.50% fee.
