Understanding cross-chain bridge risks and TED Protocol’s integration-only approach Cross-chain bridges enable token transfers between blockchains but introduce specific security considerations.

​
Why Bridges Carry Risk

Cross-chain bridges have historically been targets for major DeFi exploits. Total bridge exploits 2021-2024: Over $2 billion This history is why TED Protocol takes an integration-only approach rather than building custom bridges.

​
TED Protocol’s Approach

​
Integration-Only Model

TED Protocol does not operate its own bridge. We integrate only established, audited bridges.

​
What We Don’t Do

  • Run validators or guardians
  • Custody bridged assets
  • Modify bridge contracts
  • Create wrapped tokens

​
What We Do

  • Call official bridge SDKs
  • Use verified contract addresses
  • Display bridge selection transparently
  • Monitor transfer completion

​
Bridge-Specific Risks

​
Circle CCTP

Uses centralized attestation by Circle. Why it’s secure: Same entity that issues USDC attests transfers → no third-party trust required, native mint/burn means no wrapped tokens

​
LayerZero

Uses Decentralized Verifier Networks (DVNs). Why it’s secure: 2-of-3 DVN consensus required, independent reputable parties, no single point of failure, open-source and audited

​
Wormhole

Uses a guardian network of 19 validators. Post-2022 improvements:
  • Complete security overhaul
  • Increased guardian count and diversity
  • Enhanced monitoring and response
  • $10M+ bug bounty program

​
Risk Comparison

​
User Protections

​
Before Transfer

  • Bridge selection shown in UI
  • All costs displayed upfront
  • Expected completion time shown
  • Minimum amount validation

​
During Transfer

  • Real-time status tracking
  • Direct links to bridge explorers
  • Automatic retry for stuck transfers

​
After Transfer

  • Completion notification on fund arrival
  • Full transaction history recorded
  • Support escalation for unresolved issues

​
What If a Bridge Fails?

​
Temporary Failure

Bridge is slow or temporarily unavailable.
  • Transfer is delayed, not lost
  • Automatic retry mechanisms activate
  • Manual retry available
  • Funds remain safe on source chain until confirmed

​
Security Incident

An exploit is discovered. Important: Funds not controlled by TED Protocol are not at risk. Users can always withdraw to source chain.

​
Best Practices

​
Minimize Bridge Exposure

  • Use native bridges when possible (CCTP for USDC is safest)
  • Don’t bridge more than needed
  • Split large transfers
  • Verify destination address before confirming

​
Monitor Your Transfers

  • Don’t close browser during cross-chain transfers
  • Save transaction hash for troubleshooting
  • Check bridge explorers for independent verification
  • Contact support if transfer seems stuck (don’t assume funds are lost)

​
Emergency Procedures

​
If Transfer Stuck More Than 1 Hour

  1. Check bridge explorer (LayerZero Scan, Wormhole Scan)
  2. Verify source transaction confirmed
  3. Check destination chain for pending transactions
  4. Use manual retry if available
  5. Contact TED Protocol support if needed

​
If You Suspect an Issue

  • Do not send additional transfers
  • Screenshot all transaction details
  • Check TED Protocol and bridge protocol status pages
  • Report concerns to security@tedprotocol.io
