Meter Passport Review: Is It Safe to Use Now?

Meter Passport is a cross-chain bridge built for the Meter ecosystem. A bridge is used to move assets between blockchain networks; it does not make the same token native to every chain, and routes usually involve transactions on both the sending and receiving networks. Meter Passport lists Ethereum, BNB Chain, Theta, Moonriver, Meter, Avalanche, Moonbeam and Polygon. The project description says Meter chain acts as a relay chain, where relayers validate and vote on cross-chain transfers and messages. The available details do not identify which specific tokens or routes are supported, so a chain appearing on the list is not proof that every asset can be moved there. Most importantly, the bridge site currently says transfers are temporarily unavailable because it is under maintenance. Treat Meter Passport as unavailable until that status changes; do not send assets to an address or contract in the hope that the transfer will complete later.

The listed network set gives Meter Passport a role as a connector between Meter and several other ecosystems, including Ethereum, BNB Chain, Avalanche and Polygon. That could be useful if you hold an asset on one of those networks and need a route into or out of Meter. However, no live routes or supported-token list is provided in the project details, and transfers are currently paused. You should not infer route availability from the network list alone. Before using any bridge after service resumes, confirm that the exact token, sending network and receiving network are shown in the official interface. Check that the receiving wallet supports the destination chain and token as well. A token represented on one chain may be a bridged version rather than the original asset, so verify what you would receive before approving a transfer.

Meter Passport does not publish a fee schedule in the project details, so you cannot establish its bridge charge from the published description. If service resumes, review the amount you will receive and any displayed bridge fee before confirming. You will also generally need to pay transaction gas on the source chain; a separate destination-chain transaction may involve costs too, depending on how the bridge completes the transfer. Those network charges vary with the chain and network conditions, and are distinct from a bridge’s own fee. Do not rely on an old quote or assume a transaction is free. Since transfers are currently unavailable, there is no usable live quote to assess now. If an interface later offers a route, compare the estimated amount received with the amount sent and check for slippage or other deductions before proceeding.

Meter Passport’s described security model uses a 3-of-5 multisignature contract: three of five signers must approve a transfer. Its description names independent professional staking service providers, including Protofire, HashQuark, Infinity Stones and Wetez, as well as the Meter team, as relayers. This offers multiple signers, but it still means users depend on a signer threshold and the bridge’s contract and operating processes. It is not equivalent to a bridge where users retain unilateral control over assets throughout the transfer. No audits are listed, and the project details do not establish a licence or publish a record of security incidents. Treat the multisig as a material custody and operational risk, especially for large transfers. Do not deposit funds while service is paused, and reassess the risks if the bridge returns.

The main usability fact is that the bridge currently cannot be used: its site says transfers are temporarily unavailable during maintenance. There is no confirmed current transfer speed, and the project details do not specify supported wallets, a mobile app, or a timeline for returning to service. A bridge normally requires you to connect a wallet on the source chain, select a supported asset and destination, then approve and submit transactions. That general process does not mean those steps will work on Meter Passport now. Do not approve unexpected wallet requests or send assets directly to a contract while the interface reports maintenance. Wait until the official interface clearly shows that transfers are back, then check the route, destination address and transaction terms before signing. If a transfer still appears pending, avoid repeating it until you have verified its status.

For now, the safe choice is not to initiate a transfer. Check the official Meter Passport interface for an explicit maintenance update and a working route; do not rely on third-party claims that service has resumed. When transfers are available again, confirm the exact token and both chains, inspect the receiving address and estimated amount, and read the displayed fee before approving anything. Start with a small amount only if the route is clearly active and you can afford the risk of delay or loss. Keep enough native gas token for transactions on the relevant networks. A successful source-chain transaction alone does not prove the destination transfer has completed, so verify receipt on the destination chain before sending more. If the site remains unavailable, use another bridge only after independently checking its route, security model and costs.
