# Security

There are two security aspects involved in liquidity mining VoltSwap:

1. Meter Passport bridge security.  The Meter passport is secured by 5 experienced cross-chain relayers including Protofire, Hashquark, Wetez, InfintyStones, and Meter through Multisig contracts on different chains.  A cross-chain transaction requires 3 out of the 5 relayers to sign off.  The infrastructure was used by Moonbeam/Moonriver, Ampleforth, and Avalanche for cross-chain bridging.
2. Smart contract security.  The Voltswap ve (3,3) is a fork of Dystopia which are audited smart contracts.
