Cross-Protocol Yield Aggregator Deposit Router

WHAT IT DOES

Cross-Protocol Yield Aggregator Deposit Router enables users to deposit assets into one or more yield-generating protocols through a single router contract. The tool fetches real-time APY/APR rates, TVL, and fees from multiple yield protocols that the user specifies, then allows the user to allocate their deposit across protocols using custom weights or automatic optimization for the highest APY. The router handles the multi-protocol deposit in a single transaction, significantly reducing gas costs compared to depositing into each protocol individually.

This tool is essential for DeFi users who want to diversify their yield-generating positions across multiple protocols to manage risk and maximize returns. It provides transparent visibility into protocol performance and enables efficient, batched deposits through a router contract.

HOW TO USE

1. Connect your EVM wallet to the network where the router and yield protocols are deployed.

2. Enter the router contract address and the asset token address.

3. Add yield protocols by entering protocol address and weight percentage per line (e.g., 0x...,50 for 50% allocation).

4. Enter your total deposit amount.

5. Click "Fetch Rates" to retrieve APY, TVL, and fee data for each protocol from on-chain sources.

6. Review the comparison table showing each protocol's APY, TVL, and your allocation.

7. Click "Deposit" to approve the token spend and execute the multi-protocol deposit through the router.

8. Track progress via the status bar and confirmation of the transaction hash upon completion.

TECHNICAL MECHANISM

The tool reads yield protocol state using view functions: getAPY() or getRate() for annual percentage yield, totalValueLocked() for TVL, and getFee() for withdrawal or performance fees. It calculates the allocation for each protocol based on user-defined weights, then prepares the deposit data for the router contract. The tool attempts two router function signatures: deposit(token, amount, protocols[], amounts[]) for exact amount allocation, and depositMulti(token, amount, protocols[], percentages[]) for percentage-based allocation. Gas estimation applies a 20% buffer, and actual gas costs are calculated from receipt.effectiveGasPrice. The tool validates token balance and allowance before submission, and displays real-time APY comparisons to help users make informed allocation decisions.

WHAT IT CANNOT SEE

This tool cannot guarantee that the chosen yield protocol will maintain its APY or perform as expected—APY rates are dynamic and can change rapidly. It cannot predict future changes in interest rates, market conditions, or protocol strategies. It cannot account for protocol-specific risks such as hacks, governance changes, depegs, or strategy failures beyond the on-chain data available. It cannot verify the security of the underlying strategies; the tool does not audit or validate protocol contracts. It cannot manage deposits across protocols that require different asset wrappers or approval mechanisms beyond standard ERC-20 approvals. It cannot recover funds if the router contract is compromised, malicious, or contains a bug. The tool does not perform risk analysis or simulate protocol performance; it only aggregates publicly available data.

PLEASE NOTE

EVM chains only. This tool requires a router contract that implements the multi-deposit interface. Not all routers support all protocols—verify that the router supports the protocols you are depositing into. The tool does not verify that the router contract is safe or audited; users must trust the router. Always test with a small amount before depositing significant funds. The tool does not execute withdrawals; it only handles deposits.
