Node Operator Bond Poster

WHAT IT DOES

Node Operator Bond Poster connects to any EVM-based bond contract and enables you to post collateral bonds for node operators with a single click. The tool reads comprehensive contract state including current bond amount, minimum bond requirement, token address, user address, operator address, current block timestamp, bond history, operator performance metrics, bonding period, and slashing conditions. It then displays your current bond, minimum bond requirement, bonding period, slashing conditions, token type, and bond status. When you enter a valid bond amount, the tool enables a one-click bond posting transaction. The tool handles multiple bond function signatures (postBond, depositBond, executeBondPosting) 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 bond status. This is ideal for node operators who need to post collateral to register and operate nodes in Proof-of-Stake or restaking networks.

HOW TO USE

Connect your Web3 wallet (MetaMask, WalletConnect, or any EIP-1193 provider). Select the correct network for your bond contract — the tool supports Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche C-Chain, and BNB Chain. Paste your bond contract address into the input field. The tool reads the contract using a default ABI that covers standard bond posting functions, but you can paste a custom ABI if your contract uses non-standard naming. Enter the bond amount you want to post. Optionally enter an operator address if different from your own. Review the displayed data carefully: current bond amount, minimum bond requirement, bonding period, slashing conditions, token type, and bond status. The status indicator will show "Active" when the bond is active, "Posted" after successful posting, "Pending" while processing, or "Eligible" when you are eligible to post. When you have entered a valid amount, the "Post bond" button becomes enabled. Click it to submit the bond posting 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 bond status.

THE REAL MECHANISM

This tool does not assume a single bond interface — it adapts to the contract's actual implementation. It first detects the correct bond function by testing common names (postBond, depositBond, executeBondPosting) through static calls, falling back to the user-provided name if none are found. For bond data, the tool reads currentBond(yourAddress) to display your existing bond, minBond() to show the minimum requirement, bondingPeriod() to display the lockup duration, slashingConditions() to show the penalty terms, token() to identify the bond currency, and bondStatus() to determine the current state (0=active, 1=posted, 2=pending, 3=eligible). The tool enables the bond button only when you have entered a valid amount. When you execute the bond posting, the tool calls the contract's bond function with the amount you specify, which deposits the collateral and registers you as a node operator. 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

Node Operator Bond Poster cannot verify that the node operator will perform as expected or that the operator will maintain good behavior. It cannot detect if the operator has been slashed, penalized, or is experiencing downtime. It cannot guarantee that the bond will be returned or that the slashing conditions will be correctly applied. It cannot ensure that the bond contract has not been upgraded, modified, or paused by its owner. It cannot prevent the operator from being slashed or the bond from being forfeited. It cannot recover funds if the bond posting transaction fails due to contract bugs, out-of-gas errors, or network conditions. It cannot verify that the operator is eligible for bonding or that the eligibility criteria are accurate. It cannot detect if the bond contract is malicious or contains hidden fee structures. It cannot validate that the bond calculation is correct or that the bonding period is accurately represented. It cannot predict future slashing events, bond requirements, or changes in the bonding rules.

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 bond contract's implementation and the posting logic defined therein. Always verify the bond contract address and slashing conditions directly on-chain before posting a bond.
