This guide helps you migrate from the beta versions of the Swig TypeScript SDK to the completely refactored v1.0 release.

​
Overview of Changes

The v1.0 release represents an overhaul with some breaking changes.

​
Key Changes

  1. Modular Architecture: Core logic moved to @swig-wallet/lib
  2. Instruction-Based API: Functions return TransactionInstruction[] instead of single instructions
  3. Simplified Package Structure: @swig-wallet/classic now acts as a thin wrapper
  4. Updated Dependencies: Moved from @solana/spl-token to @solana-program/token

​
Package Changes

​
Before (Beta)

import {
  Actions,
  createSwig,
  Ed25519Authority,
  addAuthorityInstruction,
  signInstruction,
} from "@swig-wallet/classic";

​
After (v1.0)

​
For Web3.js 1.x applications:

import {
  Actions,
  getCreateSwigInstruction,
  createEd25519AuthorityInfo,
  getAddAuthorityInstructions,
  getSignInstructions,
} from "@swig-wallet/classic";

​
For Web3.js 2.0 applications:

import {
  Actions,
  getCreateSwigInstruction,
  createEd25519AuthorityInfo,
  getAddAuthorityInstructions,
  getSignInstructions,
} from "@swig-wallet/kit";

​
After (v1.0)

import {
  Actions,
  getCreateSwigInstruction,
  createEd25519AuthorityInfo,
  getAddAuthorityInstructions,
  getSignInstructions,
} from "@swig-wallet/classic";

​
Function Migrations

​
Creating a Swig

​
Before (Beta)

const rootAuthority = Ed25519Authority.fromPublicKey(user.publicKey);
const rootActions = Actions.set().manageAuthority().get();
const tx = await createSwig(
  connection,
  id,
  rootAuthority,
  rootActions,
  user.publicKey,
  [user],
);

​
After (v1.0)

const rootAuthorityInfo = createEd25519AuthorityInfo(user.publicKey);
const rootActions = Actions.set().manageAuthority().get();

const createSwigIx = await getCreateSwigInstruction({
  payer: user.publicKey,
  id,
  actions: rootActions,
  authorityInfo: rootAuthorityInfo,
});

const transaction = new Transaction().add(createSwigIx);
const signature = await sendAndConfirmTransaction(connection, transaction, [
  user,
]);

​
Adding Authorities

​
Before (Beta)

const addAuthorityIx = await addAuthorityInstruction(
  rootRole,
  rootUser.publicKey,
  createEd25519AuthorityInfo(newAuthority.publicKey),
  actions,
);

const transaction = new Transaction().add(addAuthorityIx);

​
After (v1.0)

const addAuthorityInstructions = await getAddAuthorityInstructions(
  swig,
  rootRole.id,
  createEd25519AuthorityInfo(newAuthority.publicKey),
  actions,
);

const transaction = new Transaction().add(...addAuthorityInstructions);

​
Signing Instructions

​
Before (Beta)

const signedTransfer = await signInstruction(
  tokenRole,
  tokenAuthority.publicKey,
  [transferIx],
);

const transaction = new Transaction().add(signedTransfer);

​
After (v1.0)

const signedTransferInstructions = await getSignInstructions(
  swig,
  tokenRole.id,
  [transferIx],
);

const transaction = new Transaction().add(...signedTransferInstructions);

​
PDA Derivation

​
Before (Beta)

const [swigAddress] = findSwigPda(id);

​
After (v1.0)

const swigAddress = findSwigPda(id);

​
Authority Creation Changes

​
Before (Beta)

const rootAuthority = Ed25519Authority.fromPublicKey(user.publicKey);

​
After (v1.0)

const rootAuthorityInfo = createEd25519AuthorityInfo(user.publicKey);

​
Import Changes

​
Core Classes

  • Actions class is now imported from @swig-wallet/lib (re-exported by @swig-wallet/classic)
  • Swig class is now imported from @swig-wallet/lib (re-exported by @swig-wallet/classic)
  • Authority classes have been replaced with info creation functions

​
Function Naming

  • createSwig() → getCreateSwigInstruction()
  • addAuthorityInstruction() → getAddAuthorityInstructions()
  • signInstruction() → getSignInstructions()
  • removeAuthorityInstruction() → getRemoveAuthorityInstructions()

​
Dependency Updates

​
For Web3.js 1.x applications:

{
  "dependencies": {
    "@swig-wallet/classic": "^1.0.0",
    "@solana-program/token": "^0.5.1",
    "@solana/web3.js": "^1.98.0"
  }
}

​
For Web3.js 2.0 applications:

{
  "dependencies": {
    "@swig-wallet/kit": "^1.0.0",
    "@solana-program/token": "^0.5.1",
    "@solana/kit": "^2.1.0"
  }
}

Remove old dependencies:

npm uninstall @solana/spl-token

Remove old dependencies:

npm uninstall @solana/spl-token

​
Migration Checklist

  • Update package dependencies
  • Replace single instruction functions with instruction array functions
  • Update authority creation from classes to info functions
  • Update PDA derivation calls
  • Replace Ed25519Authority.fromPublicKey() with createEd25519AuthorityInfo()
  • Update transaction building to spread instruction arrays
  • Test all functionality with the new API
  • Update error handling for new function signatures

​
Common Migration Issues

​
Issue: Functions returning arrays instead of single instructions

Solution: Use the spread operator when adding to transactions:

// Before
transaction.add(instruction);

// After
transaction.add(...instructions);

​
Issue: Authority class methods no longer available

Solution: Use the Swig instance methods instead:

// Before
const role = authority.findRole();

// After
const swig = await fetchSwig(connection, swigAddress);
const role = swig.findRolesByEd25519SignerPk(publicKey)[0];

​
Issue: Import errors for removed classes

Solution: Replace with new function-based API:

// Before
import { Ed25519Authority } from "@swig-wallet/classic";
const auth = Ed25519Authority.fromPublicKey(pk);

// After
import { createEd25519AuthorityInfo } from "@swig-wallet/classic";
const authInfo = createEd25519AuthorityInfo(pk);

Getting Help

If you encounter issues during migration:

  1. Check the API documentation
  2. Review the updated tutorials
  3. Examine the example code
  4. Open an issue on the GitHub repository

The v1.0 release is designed to be more consistent and composable, making it easier to build complex Swig applications once you’ve completed the migration.
