VEA is a trust-minimized optimistically-verified bridge with bonded participants, known as the validators, running a light client to fulfill the roles of oracle, challenger and relayer.
As opposed to other implementations that connect every bridge contract with each other using an off-chain routing network, each VEA bridge is composed of a logical pair of contracts (1-to-1 for each connection).
In the worst case scenario, VEA just falls back to the native bridge. No risk of losing funds.
VEA has the same trust model as Optimistic Rollups, requires only 1 of N parties to be honest. There is no 3rd party validator.
Unlike most bridges, there is no multi-sign admin access.
Contracts are not upgradable.
Arbitrary message passing between EVM chains.
Interacting with the protocol is permissionless at every level.
Bridge your messages for free, no fees, pay only for gas.
We encourage the projects relying on Vea to participate in the upkeep of the bridging protocol by running the open-source light client.
Cross-chain governance voting and proposal execution.
For high-value transactions with high security requirements.
Transactions from optimistic rollups requiring a faster bridging than the default 7 days.
The validators deposit a stake to bridge each message batch and pay for the transaction gas. The deposit is returned to honest validators. The validators may receive various incentives in a future version.
