vBNT is the governance token for Bancor. Users who stake BNT tokens will get vBNT in return, which is used to vote in the Bancor DAO, on-chain using Snapshot.
Step 1 - Stake your vBNT
When using vBNT to vote, you will need to deposit your vBNT in the governance contract as a first step. This is done using the vote page and clicking on "Stake Tokens". When withdrawing, there’s a 72-hour lockup period to withdraw vBNT from the governance contract.
Step 2 - Vote on Snapshot
You can see all the active proposals and cast your vote. See Bancor Governance Voting Guide.
