Para Server SDK provides seamless integration with the Sui blockchain. Once you've set up and authenticated your Para Server client, the Sui integration works identically to the client-side implementation.

<Note>
  Before using these integrations, ensure you've completed the server setup by importing a client session or creating a pregenerated wallet. See the <Link label="Server Setup Guide" href="/v3/server/setup" /> for details.
</Note>

## Installation

Install the required dependencies:

<CodeGroup>
  ```bash npm theme={null}
  npm install @getpara/sui-sdk-integration @mysten/sui --save-exact
  ```

  ```bash yarn theme={null}
  yarn add @getpara/sui-sdk-integration @mysten/sui --exact
  ```
</CodeGroup>

## Implementation

`createParaSuiSigner` returns a `@mysten/sui` `Signer` backed by the Para wallet's Ed25519 key. The raw signing is delegated to Para's MPC, while intent wrapping, hashing, and signature serialization come from `@mysten/sui`.

```typescript theme={null}
import { Para as ParaServer } from "@getpara/server-sdk";
import { createParaSuiSigner } from "@getpara/sui-sdk-integration";
import { Transaction } from "@mysten/sui/transactions";
import { SuiGrpcClient } from "@mysten/sui/grpc";

// Para server client (already authenticated)
const paraServer = new ParaServer("YOUR_API_KEY");

// Set up the Sui client
const client = new SuiGrpcClient({ network: "mainnet", baseUrl: "https://fullnode.mainnet.sui.io:443" });

// Create the Sui signer
const signer = createParaSuiSigner({ para: paraServer });
console.log(`Sui address: ${signer.address}`);

// Build a transaction: split 1 MIST off gas and send it back to ourselves.
const tx = new Transaction();
tx.setSender(signer.address);
const [coin] = tx.splitCoins(tx.gas, [1]);
tx.transferObjects([coin], signer.address);

const bytes = await tx.build({ client });

// Sign and submit
const { signature } = await signer.signTransaction(bytes);
const result = await client.executeTransaction({ transaction: bytes, signatures: [signature] });
console.log(`Transaction digest: ${result.Transaction.digest}`);
```

## Multisig

The same server client can act as one member of a native Sui multisig. Build the member list, sign the Para member's share, and combine partials:

```typescript theme={null}
import { createParaSuiSigner, createParaSuiMultiSigSigner } from "@getpara/sui-sdk-integration";
import { Ed25519Keypair } from "@mysten/sui/keypairs/ed25519";

const coSigner = new Ed25519Keypair();

const multiSigSigner = createParaSuiMultiSigSigner({
  para: paraServer,
  otherMembers: [{ publicKey: coSigner.getPublicKey(), weight: 1 }],
  threshold: 2,
});

const { signature: paraPartial } = await multiSigSigner.signTransaction(bytes);
const { signature: coPartial } = await coSigner.signTransaction(bytes);
const combined = multiSigSigner.combine([paraPartial, coPartial]);
```

## Best Practices

* Build transactions against a client connected to the correct network (`mainnet`, `testnet`, or `devnet`).
* Ensure the sending address holds enough SUI for gas before building.
* Verify signatures with the signer's public key (`getPublicKey().verifyTransaction`) when needed.
