​
Wallet architecture

Supermission uses Privy’s MPC (Multi-Party Computation) infrastructure to give users a crypto wallet without any of the traditional pain points — no seed phrases, no gas management, no chain switching.

​
How it works

1

User signs up

Email, Google OAuth, or connect an existing wallet (MetaMask, Coinbase Wallet, WalletConnect).
2

MPC wallet created

Privy generates a smart wallet on Base. The private key is split into multiple shards using MPC — no single party (including Supermission or Privy) ever has the full key.
3

Key reconstruction on sign-in

When you authenticate, the key shards are reconstructed securely in a trusted execution environment. You can sign transactions without ever seeing or managing a private key.
4

Transactions signed locally

Every trade is signed by your wallet. The signed transaction is submitted to the blockchain. Supermission cannot execute transactions without your authentication.

Key properties

PropertyDescription
Non-custodialSupermission never holds your funds or full private key. We technically cannot access your wallet.
No seed phrasesMPC eliminates the 24-word recovery phrase. Recovery is handled through your email/social login.
Sponsored gasAll transaction gas fees are covered. You never need ETH. Trades, bridges, redemptions — all free.
No chain switchingYour wallet lives on Base. When you trade on Polymarket (Polygon), we bridge automatically. Invisible to you.
Batch transactionsMultiple operations (approve + swap, bridge + trade) can execute in a single click.

​
Multi-chain flow

Your wallet lives on Base, but trades execute on Polygon. Here’s how that works seamlessly: 
Your Base Wallet (USDC)
        │
        ▼ Circle CCTP Bridge
Polygon (USDC.e)
        │
        ▼ Polymarket CLOB
Position Created
        │
        ▼ On resolution / sell
USDC.e released on Polygon
        │
        ▼ Auto-bridge back
Your Base Wallet (USDC)
You see step 1 (confirm trade) and the last step (position in portfolio). Everything in between is invisible.

​
Authentication flow

  1. Login via Privy (email code or Google OAuth)
  2. Privy creates embedded MPC wallet on Base
  3. Wallet address assigned to your account
  4. Waitlist check — if approved, full access granted
  5. Session token stored, auto-renewed

​
Security model

Key Compromise

MPC splits your key across multiple parties. Compromising one shard is useless without the others. No single point of failure.

Phishing Protection

No seed phrase to steal. No private key to export. Authentication is through your email/social provider with Privy’s security infrastructure.

Gas Griefing

Gas is fully sponsored by Supermission. You never need to hold ETH or worry about gas price manipulation.

Front-Running

Orders go directly to Polymarket’s CLOB — not through a public mempool. No MEV exposure on your trades.
Non-custodial means non-custodial. If you lose access to your email/social login and cannot recover through Privy’s recovery flow, we cannot help you access your wallet. Secure your authentication credentials.
For developers building agents: server-side wallets are also available with AES-256 encrypted private key storage and configurable spending policies. See Agent Economy for details.
