## Webapp Environment Variables
| Variable | Default | Set in docker-compose | Purpose |
|---|---|---|---|
| `VITE_ENABLE_LOCAL_SWAP` | `false` (unset) | `true` | Show inline ETH→$KRK swap widget on Get KRK page instead of the Uniswap link. Enable for local dev; leave unset for production builds. |
| `VITE_KRAIKEN_ADDRESS` | from `deployments-local.json` | via `contracts.env` | Override KRK token address. |
| `VITE_STAKE_ADDRESS` | from `deployments-local.json` | via `contracts.env` | Override Stake contract address. |
| `VITE_DEFAULT_CHAIN_ID` | auto-detected (31337 on localhost) | — | Force the default chain. |
## Contract Addresses
After bootstrap, addresses are in `/home/debian/harb/tmp/containers/contracts.env`.
