Bridge Process Details
How Bridging Works
Polynomial uses Socket's mint and burn bridge mechanism for fast, secure cross-chain transfers:
Mint and Burn: Assets are burned on the source chain and minted on Polynomial Chain
Fast Execution: Bridge completion typically takes 10-15 seconds
Trustless: Bridge is trustless and secure
Transparent: All transactions are transparent and verifiable
Automated: Process is automated once initiated
For detailed technical information about Socket's bridge mechanism, visit the Socket.tech documentation.
Bridge Security
Smart Contracts: Secured by audited smart contracts
Multi-Sig: Multiple signatures required for bridge operations
Time Locks: Time delays for additional security
Monitoring: Continuous monitoring of bridge operations
Bridge Fees
Source Chain Gas: Pay gas fees on source chain
Bridge Fees: May include bridge-specific fees
Destination Gas: No gas fees on Polynomial Chain
Total Cost: Consider total cost of bridging

Failed Margin Deposit After Bridge
Sometimes when bridging and depositing to margin, the margin deposit may fail even though the bridge was successful:
Check Polynomial Balance: Your assets are likely already on Polynomial Chain
Direct Deposit: You can deposit directly from your Polynomial Chain balance
Balance Verification: Check your balance in the staking interface or trading interface
No Re-bridge Needed: Assets are already on Polynomial Chain, no need to bridge again
Wrong Network

Important Bridge Information
Only Use Socket Bridge
Official Bridge Only: Polynomial only supports Socket bridge for all asset transfers
No Alternative Bridges: Do not use other bridges (LayerZero, Wormhole, etc.) as they are not supported
ETH Bridge Warning: Do not use Optimism's ETH bridge unless you're running a bot - this is not recommended for regular users
WETH System
WETH Instead of ETH: Polynomial uses WETH (Wrapped ETH) on-chain, not native ETH
Polynomial Wallet Integration: All assets are managed within your Polynomial wallet
Simplified Experience: WETH provides the same functionality as ETH but optimized for Polynomial Chain
Security Considerations
Bridge Security
Official Socket Bridge Only: Always use Polynomial's official Socket bridge interface
Verify URLs: Ensure you're on correct website (polynomial.fi)
No Alternative Bridges: Do not use any other bridge services
Be Cautious: Be cautious of phishing attempts
