​
Your keys, our convenience

Security in crypto usually means one of two things: “you manage 24 words and pray you don’t lose them” or “we hold your funds and pray we don’t get hacked.” Supermission does neither.

​
Smart wallet architecture

1

Privy-powered MPC wallet

When you sign up, a smart wallet is created using Privy’s MPC (Multi-Party Computation) infrastructure. Your private key is split across multiple parties — no single entity (including us) ever has the full key.
2

Non-custodial

Supermission never holds your funds. Your wallet is yours. We can’t move your money, freeze your account, or access your private key. Technically can’t, not “promise we won’t.”
3

No seed phrases

MPC eliminates the need for a 24-word recovery phrase. You authenticate with your email or social login. The key shards are reconstructed securely when you sign in.
4

Sponsored gas

All transaction gas fees are covered by Supermission. You never need ETH for gas. Every action — trades, bridges, redemptions — just works.

​
How trades are secured

Every trade on Supermission is signed by your wallet. The flow:
  1. You confirm a trade in the UI (or via Oracle agent)
  2. Your MPC wallet signs the transaction
  3. The signed transaction is submitted to Polymarket’s contracts
  4. Execution happens on-chain — verifiable, irreversible, transparent
No one — not Supermission, not Privy, not your Oracle agent — can execute a trade without your wallet signing it. The agent confirms with you, you approve, your wallet signs. That’s the chain of custody.

​
Contract security

Supermission includes Securo, an AI-powered contract audit agent. It analyzes smart contracts for common vulnerabilities, reentrancy risks, and access control issues. Think of it as a security co-pilot for advanced users who want to inspect the contracts they’re interacting with.
All prediction market trades execute on Polymarket’s audited smart contracts. These contracts have processed billions in volume and have been reviewed by multiple security firms. Supermission interacts with them — we don’t replace them.

​
What we protect against

Key Compromise

MPC splits your key across parties. Compromising one shard is useless without the others.

Phishing

No seed phrase to steal. Email/social auth with Privy’s security infrastructure.

Gas Griefing

Gas is sponsored. You never need to hold ETH or worry about gas manipulation.

Front-Running

Orders go directly to Polymarket’s CLOB, not through a public mempool. No MEV exposure.
Non-custodial means non-custodial. If you lose access to your email/social login and can’t recover through Privy’s recovery flow, we cannot help you access your wallet. Secure your authentication credentials.
The best security is invisible security. If you’re thinking about private keys, gas fees, or RPC endpoints while trading — the UX has failed. We’ve designed Supermission so you never have to.
