Multi-Protocol Reward Claimer

WHAT IT DOES

Multi-Protocol Reward Claimer is a non-custodial tool that aggregates and claims rewards from multiple DeFi protocols in a single transaction, saving gas and time. It reads multiple reward contract states, user address, token balances, reward eligibility, claim status, reward amounts, claim windows, vesting schedules, minimum claim amounts, user's reward history, protocol-specific parameters, reward accumulation, and claim deadlines to structure the optimal claim operation. With a single transaction, it calls claimRewards(), executeMultiClaim(), or batchClaimRewards() on the target aggregator contract, claiming rewards from all listed protocols at once. The tool supports various reward types including staking rewards, liquidity mining rewards, governance incentives, and protocol-specific distributions. Instead of visiting each protocol individually to claim rewards, users can batch them all together in one efficient transaction.

HOW TO USE

1. Connect your wallet (EVM-compatible).

2. Enter reward contracts (one per line, format: address,protocolName).

3. Review the number of contracts, estimated gas, available rewards, claim windows, and vesting status.

4. Click "claim all rewards" and confirm the transaction in your wallet.

The tool attempts to claim rewards from each listed contract using the first contract as the aggregator. After the transaction confirms, all available rewards are claimed and sent to your wallet—no centralized custody, no intermediaries. This significantly reduces gas costs compared to claiming each protocol separately.

TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH BATCH CLAIM

Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts claimRewards(), then falls back to executeMultiClaim() or batchClaimRewards() if the primary method fails—automatically adapting to different aggregator contract implementations without requiring the user to know the exact function name. For all on-chain reads, it uses chunked block range scanning that halves on failure, preventing the common "eth_getLogs limit exceeded" error that halts most scanners on public RPCs. It double-verifies claim eligibility by checking the current claim status and reward amounts from storage, rather than relying on historical events—because an event log proves rewards were previously claimed, not that the current claim is available. Gas estimation uses receipt.effectiveGasPrice for accurate post-EIP-1559 cost accounting, and all batched operations are sequential with concurrency caps to avoid nonce conflicts. The tool also validates that all contract addresses are valid and checks claim windows and vesting schedules before execution.

WHAT IT CANNOT SEE

This tool cannot verify that any reward contract is legitimate or has not been compromised. It cannot detect if any protocol has been manipulated or has hidden fees. It cannot ensure that claims will execute at the optimal gas price due to network conditions. It cannot guarantee that claims will succeed if any protocol contract is paused or frozen. It cannot verify that any contract has not been upgraded or modified. It cannot detect if the trade path is optimal or not front-run. It cannot recover funds if execution fails due to contract bugs or insufficient approval. It cannot verify that reward amounts are correct or not. It cannot predict market movements, price gaps, or flash crashes. It cannot guarantee execution during extreme network congestion or volatile market conditions. It cannot detect if any underlying protocol has been compromised. It cannot prevent the user from canceling or modifying claim parameters. It cannot ensure that rewards will be distributed correctly. It cannot protect against loss if claims are made incorrectly. It cannot verify that claim windows are open for all protocols. It cannot guarantee that vesting schedules will be honored. It cannot ensure that minimum claim amounts will be met for all protocols.

PLEASE NOTE

This tool operates only on EVM-compatible chains (Ethereum, Polygon, Arbitrum, Optimism, etc.). It is non-custodial—you retain full control of your funds at all times. Always verify contract addresses and claim parameters before executing. Reward claims are irreversible—once claimed, they cannot be undone. Not all protocols support batch claiming; this tool works with aggregator contracts that support multi-claim functionality. Some rewards may be subject to vesting schedules or minimum claim amounts. Past performance does not guarantee future results. The tool is provided as-is; use at your own risk.
