Locking bridging aggregator tokens for governance typically involves staking or depositing your tokens into a smart contract to participate in decentralized governance. Here’s a step-by-step guide:
1. Identify the Governance Platform

Determine if the bridging aggregator (e.g., Multichain, Synapse, Across, Stargate) has a native governance system or uses a DAO (e.g., Snapshot, Tally, or a custom dApp).
Check the project’s official docs, Discord, or governance forum for details.
2. Connect Your Wallet
Ensure you hold the required governance tokens (e.g., SYN for Synapse, ACX for Across).
Use a Web3 wallet (MetaMask, WalletConnect, etc.) connected to the correct network (Ethereum, Arbitrum, etc.).
3. Navigate to the Governance Portal
Visit the project’s governance dashboard (e.g., Tally, Snapshot, or a custom dApp).
Examples:
Snapshot (off-chain voting): https://snapshot.org
Tally (on-chain governance): https://www.tally.xyz
Project-specific portals (e.g., Across’s governance dashboard).
4. Lock/Stake Tokens
Some platforms require locking tokens in a smart contract to gain voting power.
Example: veToken models (like Curve’s veCRV) require locking for a fixed duration.
Steps:
Go to the "Stake" or "Lock" section.
Enter the amount and lock duration (if applicable).
Confirm the transaction (gas fees apply).
5. Participate in Governance
Once locked, your voting power is active.
Propose or vote on proposals in the governance portal.
6. Unlocking (If Applicable)
Some systems allow early unlocking (with penalties), while others enforce fixed lock periods.
Popular Bridging Aggregators & Their Governance
| Project | Governance Token | Governance Platform | Locking Mechanism |
|---|---|---|---|
| Synapse | SYN | Tally, Snapshot | Staking in governance contracts |
| Across | ACX | Across DAO (custom) | Locking for voting power |
| Stargate | STG | Snapshot / LayerZero DAO | veSTG model (locked staking) |
| Multichain | MULTI | (Previously Snapshot) | Depends on DAO |
Security Tips
Always use official links (avoid phishing sites).
Verify smart contracts on Etherscan before locking tokens.
Check if the lock is time-based (e.g., 1 month, 1 year).
