# Program addresses

> On-chain program IDs per cluster

| Cluster | Program ID                                    |
| ------- | --------------------------------------------- |
| Mainnet | `pDLMMk3KW3CUSxE1Wgjhx3jSmm2spe6Ry7Mq2HT26rC` |
| Devnet  | `tDLMMKoxBt7UkZapYHsEgLGydmFvSQXh5mGzrRovoeM` |

Both are exported from the SDK for convenience:

```ts theme={null}
import { MAINNET_PROGRAM_ADDRESS, DEVNET_PROGRAM_ADDRESS } from "@picon-finance/dlmm-sdk";
```

Everywhere the SDK takes an optional `programAddress` — `DlmmProgram`'s constructor,
`events.onEvent`'s options — omitting it defaults to mainnet.
