What is OFT?
Traditional bridges lock tokens on the source chain and mint wrapped versions on the destination. This approach causes several problems:- Liquidity fragmentation
- Wrapped token complexity
- Bridge-specific security risks
| Aspect | Traditional Bridge | OFT |
|---|---|---|
| Mechanism | Lock → Mint wrapped | Burn → Mint |
| Token Type | Wrapped token (wTEDP, etc.) | Native token |
| Total Supply | Distributed per chain | Fixed 1B across all chains |
| Liquidity Pools | Required | Not required |
How Transfers Work
1
Burn
Source chain TEDP contract burns tokens
2
Message
Cross-chain message sent via LayerZero
3
Verify
Decentralized Verifier Network (DVN) validates the burn
4
Mint
Destination chain TEDP contract mints equivalent amount
Supported Chains
| Chain | Endpoint ID | Status |
|---|---|---|
| Ethereum | 30101 | Active |
| Arbitrum | 30110 | Active |
| Base | 30184 | Active |

Transfer Costs
Gas Fees
| Route | Estimated Gas |
|---|---|
| Ethereum → L2 | $10-30 |
| L2 ↔ L2 | $0.05-0.50 |
| Kaia routes | < $0.01 |
LayerZero Fees
| Item | Cost |
|---|---|
| DVN Verification | $0.01-0.10 |
| Destination Execution | $0.01-0.05 |
| Total Fee | $0.02-0.15 |
Transfer Time
| Route | Estimated Time |
|---|---|
| L2 ↔ L2 | Under 1 minute |
| Ethereum → L2 | 1-3 minutes |
| L2 → Ethereum | 1-3 minutes |
- Source chain finality (Ethereum takes longer than L2s)
- DVN verification speed
- Destination chain block time
Security Model
LayerZero uses Decentralized Verifier Networks (DVN) to secure cross-chain messages. DVN Configuration:- TEDP uses 2-of-3 DVN configuration
- Two out of three verifiers must confirm each message
| Feature | Description |
|---|---|
| Nonce-based ordering | Prevents replay attacks |
| Rate limiting | Throughput control |
| Emergency pause | Can halt all transfers if needed |
How to Transfer
Via TED Protocol Interface
1
Access swap page
2
Select TEDP token
Choose TEDP as the token to transfer
3
Choose chains
Select source and destination chains
4
Enter amount
Input the amount you want to transfer
5
Confirm transfer
Click Transfer and confirm in your wallet
Via Smart Contract
Developers can call the TEDP contract’ssend function directly:
- Use
quoteSendto estimate LayerZero fees - Execute transfer with native token fee attached
Tracking Transfers
All TEDP transfers can be tracked on LayerZero Scan:- Mainnet: layerzeroscan.com
- Testnet: testnet.layerzeroscan.com
| State | Description |
|---|---|
| Inflight | Message sent, awaiting verification |
| Verifying | DVN checking validity |
| Delivering | Executing on destination |
| Delivered | Complete |
Supply Preservation
The burn-and-mint mechanism guarantees total supply remains constant. Example:| Chain | Before Transfer | After Transfer |
|---|---|---|
| Ethereum | 400M | 399,999,900 |
| Arbitrum | 350M | 350,000,100 |
| Base | 250M | 250M |
| Total | 1B | 1B |
