Vote Power Snapshot Locker

WHAT IT DOES

Vote Power Snapshot Locker is a governance tool that lets you lock your voting power at a specific block height for governance participation. In many governance protocols, voting power is determined by token balance at a specific snapshot block — often the block when a proposal is created or when a vote begins. This tool lets you secure your voting power at a chosen block, ensuring that your participation is based on your holdings at that precise moment, even if you later transfer or delegate your tokens. It reads your current balance and voting power, simulates your voting power at the target snapshot block, and then executes the lock in a single transaction. This is particularly valuable for proposal creation, where a minimum voting power threshold must be met at the time of proposal submission.

HOW TO USE

Connect your EVM wallet via the BGWallet bridge. Enter your governance token address and the snapshot block number you want to lock your voting power at. Optionally, specify a lock duration (in blocks) to set an expiry, and an amount to lock (leave blank to lock your full balance). Click "Preview Snapshot" to see your current balance, current voting power, the snapshot block, your voting power at that block, and the lock duration. Review the snapshot details carefully. Click "Lock Snapshot" to sign and broadcast the transaction. The tool will lock your voting power at the specified block, providing a transaction hash for tracking and updating your lock status.

TECHNICAL MECHANISM

The tool queries the governance token contract to read your current balance and voting power. It then uses the provider's `getBalance` or token contract's `balanceAt` function (if available) to determine your holdings at the specified snapshot block. For ERC-20 tokens with delegation, it may call `getVotesAt` or similar view functions. When executing, the tool interacts with the governance protocol's snapshot lock or voting escrow contract — depending on the specific implementation — to record your locked voting power at the target block. The lock can be for a fixed duration (timed lock) or permanent, depending on the protocol's design. The tool encodes the lock transaction and submits it, ensuring atomicity.

WHAT IT CANNOT SEE

This tool cannot guarantee that the snapshot will be recognized by all governance protocols or that the locked voting power will be sufficient for proposal creation requirements. Different protocols have different snapshot mechanisms — some use off-chain snapshots via Snapshot.org, while others use on-chain block numbers. The tool cannot predict if the protocol will use the same block number for voting or proposal creation. Additionally, the tool cannot guarantee that your locked voting power will remain valid if the protocol's governance parameters change. Always check the specific requirements of your governance protocol before locking a snapshot. This tool is an aid for governance participation, not a guarantee of eligibility.

PLEASE NOTE

EVM chains only. This tool relies on the BGWallet connector and will not function on Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. The user is responsible for ensuring the supplied governance token address is correct and that the protocol supports snapshot locking or voting escrow functionality. Not all governance protocols support on-chain snapshots — check your protocol's documentation first.
