Zero Gas, Zero Signatures
Trading on Matchr is completely gasless. You don’t pay gas fees, and you don’t need to sign every transaction.How it works: We use Safe smart contract wallets with server-side execution. You trade with USDC—no ETH needed.
The Traditional Experience
Trading on most DeFi platforms requires:Gas Fees
Every transaction costs ETH. A single trade can cost $1-50+ depending on network congestion.
Wallet Popups
Each action triggers a signature request. Confirm, confirm, confirm…
ETH Management
Keep ETH in your wallet for gas. Bridge it when needed. Another thing to manage.
Failed Transactions
Gas price spikes can cause failures. Lost fees, wasted time.
The Matchr Experience
Zero Gas
We cover all transaction costs. You only pay trading fees (same as trading directly).
Zero Signatures
Server-side execution means no wallet popups. Click trade, it executes.
USDC Only
Fund your Safe with USDC. That’s it. No ETH management.
Always Works
Our infrastructure handles gas price spikes. Your trades go through.
How It Works
The Architecture
You Place Order
Click Buy or Sell in the Matchr interface. Enter your amount and price.

Safe Executes Trade
Our server uses your Safe’s API credentials to execute the trade on Polymarket.
Trade Confirms
The trade is recorded on-chain. Your Safe balance updates.
Why This Works
Safe Smart Contract Wallets
Safe Smart Contract Wallets
Safe (formerly Gnosis Safe) is a battle-tested smart contract wallet used by DAOs and institutions to secure billions in assets.Your funds are in a smart contract you control, not our servers.
Polymarket CLOB API
Polymarket CLOB API
Polymarket’s Central Limit Order Book (CLOB) API allows server-side order submission with delegated credentials.We derive API keys from your wallet signature once, then use them for all future trades.
Builder Attribution
Builder Attribution
We’re a registered Polymarket builder. Our server signs orders with builder credentials, enabling gasless execution while maintaining proper attribution.
One-Time Setup
To enable gasless trading, you complete a one-time setup:Deploy Safe
We deploy a Safe smart contract wallet to Polygon. This costs gas, but we pay for it.
Approve USDC
Your Safe approves USDC spending for Polymarket contracts. One signature, done forever.
Generate Credentials
We derive Polymarket API credentials from your wallet. One signature, stored securely.
Total setup time: ~30 seconds. After that, it’s pure gasless trading.
Security Model
Your Funds Are Safe
Non-Custodial
We never have access to your funds. Your Safe is controlled by your wallet.
Audited Contracts
Safe contracts have been audited multiple times and secure billions in assets.
Encrypted Credentials
API credentials are encrypted at rest and never exposed to our frontend.
Withdrawal Anytime
You can withdraw your funds from your Safe at any time. No lock-up.
