Snowflake Safe SDK

Snowflake Safe SDK provides an easy way to interact with the Snowflake Safe app and onchain programs

Installation

Install with npm

npm i @snowflake-so/safe-sdk

Install with yarn

yarn add @snowflake-so/safe-sdk

Quick start guide

Initialize Snowflake

To create a new Snowflake service, we would need to initialize with the Provider.

// if your Anchor version is older than 0.24.2,
// please use Snowflake SDK version 1.0.11 and initialize the provider as below
let provider: Provider = Provider.local(API_URL);

// if your Anchor version is 0.24.2 or later,
// please use the latest version of Snowflake SDK and initialize the provider as below
let provider: Provider = AnchorProvider.local(API_URL);

The API_URL is the endpoint to the Solana cluster. Empty API_URL is pointed to the local testnet

• Mainnet Beta: https://api.mainnet-beta.solana.com
• Testnet: https://api.testnet.solana.com
• Devnet: https://api.devnet.solana.com

let snowflakeSafe: SnowflakeSafe = new SnowflakeSafe(provider);

---

Fetch safe

Fetch safe onchain information by safe address

await snowflakeSafe.fetchSafe(safeAddress);

Fetch proposals of safe

Fetch all onchain proposals of the safe

await snowflakeSafe.fetchAllProposals(safeAddress);

Fetch proposal

Fetch onchain proposal information

await snowflakeSafe.fetchProposal(proposalAddress);

Fetch owned safes

Fetch all safes that the provided wallet owned

await snowflakeSafe.fetchOwnedSafes(ownerAddress);

---

Create a new safe

Create a new safe with one owner and approvals required as one

const input = {
  approvalsRequired: 1,
  owners: [owner],
};
const [newSafeAddress, txId] = await snowflakeSafe.createSafe(
  input.owners,
  input.approvalsRequired
);

Create a new proposal

Create a new proposal that can be executed by any safe owners

const response = await snowflakeSafe.createProposal(safeAddress, 'hello world', instructions);

Create a new recurring proposal

Create a new recurring proposal that can be executed automatically by Snowflake node operators

const proposal = new MultisigJobBuilder()
  .jobName('hello world')
  .jobInstructions(instructions)
  .scheduleCron('0 0 * * *')
  .build();

const [newProposalAddress, txId] = await snowflakeSafe.createRecurringProposal(
  safeAddress,
  proposal
);

Create a proposal with large payload

In production, there is proposal created with multiple actions which has bunches of accounts. This method is used to solve the issue

const [newProposalAddress] = await snowflakeSafe.createProposal(
  safeAddress,
  'hello world',
  instructions,
  [],
  DEFAULT_FLOW_SIZE,
  true,
  true // Set separatedActions parameter to true
);

Update an existing safe

Add owner proposal

The method will create a new instruction to propose adding new owner to the safe

const ix = await snowflakeSafe.createAddOwnerProposalInstruction(safeAddress, newOwner);

Remove owner proposal

The method will create a new instruction to propose removing an existing owner from the safe

const ix = await snowflakeSafe.createRemoveOwnerProposalInstruction(safeAddress, newOwner);

Change threshold proposal

The method will create a new instruction to propose changing threshold of the safe

const ix = await snowflakeSafe.createChangeThresholdProposalInstruction(safeAddress, newThreshold);

Approve a proposal

await snowflakeSafe.approveProposal(flowAddress);

Reject a proposal

await snowflakeSafe.rejectProposal(flowAddress);

Execute a proposal

await snowflakeSafe.executeProposal(flowAddress);

Abort a recurring proposal

await snowflakeSafe.abortRecurringProposal(flowAddress);

Build an once-off scheduled job

With Snowflake SDK, you can create a job with two line of code.

const job = new MultisigJobBuilder()
  .jobName('hello world')
  .jobInstructions(instructions)
  .scheduleOnce(tomorrow())
  .build();

Build a recurring scheduled job

Schedule a job that runs every minute for 10 times.

const job = new MultisigJobBuilder()
  .jobName('hello world')
  .jobInstructions(instructions)
  .scheduleCron('* * * * *', 10)
  .build();

Schedule a job that runs at 10:00 AM on the first day of every month .

const job = new MultisigJobBuilder()
  .jobName('hello world')
  .jobInstructions(instructions)
  .scheduleCron('0 10 1 * *')
  .build();

Build a program condition triggered job

Schedule a job that is triggered based on an arbitrary condition defined within the user program.

const job = new MultisigJobBuilder()
  .jobName('hello world')
  .jobInstructions(instructions)
  .scheduleConditional(1)
  .build();
