Kusama's Privacy Vision

The Kusama community has agreed to fund, research, and embrace privacy-friendly technology. Read more about Kusama's new vision here.

Kusama was born in Berlin to be an unstoppable force of nature that we tap into to serve a multichain future with the Kusama Shield privacy protocol.

Tornado Cash, Samurai Wallet and previous privacy projects have all failed

Kusama is governed by the same decentralized governance system that Polkadot uses. It's the most advanced, resilient and decentralized governance system on earth, ensuring no bribes or shady middlemen can change or censor core functionality.

Backed by Kusama's DAO

Kusama Shield is backed by the resilient, uncensorable DAO of Kusama. We don't answer to Venture Capital, Compliance Trolls, or legal threats. Kusama Shield lives autonomously on a decentralized network without any single authority, producing immutable privacy.

Trustless Crosschain interactions

Low transaction fees

Decentralized allocation with crowdloan mechanism and limited parachain slots.

CROSS-CHAIN MESSAGING

By tapping into the security umbrella of Polkadot and Kusama, we are able to utilize trustless message protocols such as XCM and ISMP. Permissionlessly send your funds

0.5% cross chain swap fee

Send tokens without high fees and with no hassle

Integrate

📦 TypeScript / Node.js SDK

@kusama-shield/shielded-transfers — ethers.js v6, snarkjs Web Worker or wasmsnark, full React Provider + hooks.

🐍 Python SDK

shielded-transfers — web3.py, server/CLI/scripts, snarkjs or rapidsnark, Substrate revive.call support.

🔑 Shared Crypto

Both SDKs use the same Poseidon hashing, Groth16 proving and LeanIMT tree structure.

Shield in a few lines

Typescript — shield (deposit)

import { simpleShield, parseAmount, POLKADOT_CONFIG } from "@kusama-shield/shielded-transfers"; await simpleShield( wallet.address, parseAmount("0.1", 18), // 0.1 DOT undefined, // secret auto-generated POLKADOT_CONFIG.contractAddress, POLKADOT_CONFIG.rpcUrl, );

Typescript — unshield (withdraw)

import { simpleUnshield, POLKADOT_CONFIG } from "@kusama-shield/shielded-transfers"; await simpleUnshield( wallet.address, secret, // your deposit secret POLKADOT_CONFIG.contractAddress, POLKADOT_CONFIG.rpcUrl, );

Python — full roundtrip

from shielded_transfers import ShieldedClient, POLKADOT_ASSET_HUB client = ShieldedClient( rpc_url=POLKADOT_ASSET_HUB["rpc"], pool_address=POLKADOT_ASSET_HUB["pool"], private_key="0xYOUR_PRIVATE_KEY", deployment_block=POLKADOT_ASSET_HUB["deployment_block"], ) note = client.deposit(int(0.1 * 1e18)) # 0.1 DOT client.withdraw(note) # unshield to yourself
