Validator Self-Bond Top-Up Tool

WHAT IT DOES

Validator Self-Bond Top-Up Tool connects to any EVM-based validator contract and enables you to increase your validator's self-bond with a single click. The tool reads comprehensive contract state including current self-bond amount, minimum self-bond requirement, token address, user address, validator address, current block timestamp, self-bond history, validator performance metrics, and bonding period. It then displays your current self-bond, minimum requirement, bonding period, token type, and status. When you are the validator and have entered a valid top-up amount, the tool enables a one-click top-up transaction. The tool handles multiple top-up function signatures (topUpSelfBond, addSelfBond, increaseBond) and automatically detects the correct function to call. After submission, the tool displays the transaction hash and refreshes the contract data to show the updated self-bond amount. This is ideal for validators who need to increase their own stake to meet minimum requirements, strengthen their position, or attract more delegators.

HOW TO USE

Connect your Web3 wallet (MetaMask, WalletConnect, or any EIP-1193 provider). Select the correct network for your validator contract — the tool supports Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche C-Chain, and BNB Chain. Paste your validator contract address into the input field. The tool reads the contract using a default ABI that covers standard self-bond functions, but you can paste a custom ABI if your contract uses non-standard naming. Enter the amount you want to add to your self-bond. Review the displayed data carefully: current self-bond amount, minimum self-bond requirement, bonding period, token type, and bond status. The status indicator will show "Active" when the contract is operational, "Bonded" after successful top-up, "Pending" while processing, or "Ready" when you are eligible to top up. When you are the validator and have entered a valid amount, the "Top up self-bond" button becomes enabled. Click it to submit the top-up transaction — the tool will show a confirmation dialog with all details, submit the transaction with the correct native token value, and wait for confirmation. After successful execution, the contract data refreshes automatically to show the updated self-bond amount.

THE REAL MECHANISM

This tool does not assume a single top-up interface — it adapts to the contract's actual implementation. It first detects the correct top-up function by testing common names (topUpSelfBond, addSelfBond, increaseBond) through static calls, falling back to the user-provided name if none are found. For self-bond data, the tool reads currentSelfBond(yourAddress) to display your current stake, minSelfBond() to show the minimum requirement, bondingPeriod() to display the lockup duration, token() to identify the staking currency, and bondStatus() to determine the current state (0=active, 1=bonded, 2=pending, 3=ready). The tool enables the top-up button only when you are the validator and have entered a valid amount. When you execute the top-up, the tool calls the contract's top-up function with the amount you specify, which adds the specified tokens to your validator's self-bond. All transaction parameters are estimated using eth_estimateGas and sent with the wallet's preferred gas strategy. The tool monitors the transaction receipt and extracts the effectiveGasPrice to display actual gas cost, not the cap.

WHAT IT CANNOT SEE

Validator Self-Bond Top-Up Tool cannot verify that the self-bond top-up will improve validator performance or attract more delegators. It cannot detect if the self-bond requirement has been changed without notice or if the requirement will increase after your top-up. It cannot guarantee that the self-bond will be recognized correctly or that the bonding period will be honored. It cannot ensure that the validator contract has not been upgraded, modified, or paused by its owner. It cannot prevent the validator from withdrawing the self-bond later or from losing the self-bond due to slashing. It cannot recover funds if the top-up transaction fails due to contract bugs, out-of-gas errors, or network conditions. It cannot verify that the self-bond is within allowed limits or that the amount is appropriate. It cannot detect if the validator is malicious or contains hidden fee structures. It cannot validate that the self-bond calculation is correct or that the bonding period is accurately represented. It cannot predict whether the self-bond will effectively secure the validator's position or improve the validator's standing.

PLEASE NOTE — EVM CHAINS ONLY

This tool works exclusively with EVM-compatible blockchains. Non-EVM chains are not supported. The tool does not deploy contracts, manage private keys, or sign anything outside the connected wallet's secure environment. It is a read-and-execute interface that relies entirely on the validator contract's implementation and the self-bond logic defined therein. Always verify the validator contract address and self-bond requirements directly on-chain before topping up.
