The Lamina1 core team has developed a token bridge utilizing Avalanche's Interchain Token Transfer (ICTT) protocol, enabling seamless transfers of native and ERC20 tokens between Avalanche C-Chain and Lamina1 Network (formerly Avalanche subnets). This guide covers everything users and developers need to know about cross-chain token movements.
Key Features of the Lamina1 Token Bridge
- Launch Date: March 3, 2025 (coinciding with L1 token listing)
- Supported Tokens: L1 (native token) and AVAX
Technology Stack:
- Avalanche Teleporter protocol
- InterChain Messaging (ICM)
- EVM-compatible execution

How InterChain Messaging (ICM) Works
ICM (previously Avalanche Warp Messaging) facilitates secure communication between Avalanche L1s by:
- Validators registering BLS public keys on Avalanche P-Chain
- Using BLS signatures to verify cross-chain messages
- Durango upgrade enabling warp messaging precompile for EVM execution
Step-by-Step: Using the Lamina1 Token Bridge
Prerequisites
- Lamina1 Hub account (wallet link)
- Metamask wallet connected to both networks
- Small AVAX reserve for gas fees (see fee table below)
| Transaction Type | Required Currency | Estimated Fee |
|---|---|---|
| Lamina1 โ Avalanche | AVAX | 0.01 AVAX |
| Avalanche โ Lamina1 | L1 | 0.005 L1 |
Bridging Tokens: Two Common Scenarios
Scenario 1: Transferring L1 from Avalanche to Lamina1
- Acquire AVAX from exchange โ Metamask
- Trade AVAX for L1 on Avalanche DEX (save 0.01 AVAX)
In Lamina1 Wallet:
- Set Origin: Avalanche
- Set Destination: Lamina1
- Confirm cross-chain transfer
Scenario 2: Moving L1 from Lamina1 to Avalanche
- Export Lamina1 private key to Metamask
- Acquire 0.01 AVAX for bridge fee
In Lamina1 Wallet:
- Set Origin: Lamina1
- Set Destination: Avalanche
- Pay AVAX fee โ Execute transfer

Technical Deep Dive: Bridge Contract Workflow
Outbound Transfer (Lamina1 โ Avalanche)
- User prepays relayer fee in AVAX
- L1 tokens locked โ Wrapped L1 (WL1) created
- Teleporter message sent via ICM
- Relayer submits to Avalanche contract
- L1 ERC20 minted on destination chain
Inbound Transfer (Avalanche โ Lamina1)
- L1 ERC20 burned on Avalanche
- ICM message triggers Lamina1 contract
- WL1 unwrapped โ Native L1 released
- Tokens delivered to target address
Future Developments
- Expanded token support (ERC20, ERC721)
- Additional blockchain integrations
- Enhanced relayer decentralization
FAQ: Lamina1 Token Bridge
Q: What's the minimum transfer amount?
A: No protocol-enforced minimum, but consider gas fees.
Q: How long do transfers take?
A: Typically 2-5 minutes depending on network congestion.
Q: Can I bridge other tokens besides L1?
A: Currently only L1 and AVAX are supported.
Q: Is there a mobile wallet option?
A: Yes! Use Metamask Mobile with the same credentials.
Q: What if my transfer gets stuck?
A: Contact Lamina1 support with your transaction hash.
Q: Are bridge transactions reversible?
A: No - always verify destination addresses before sending.
