DZap Mega Aggregator facilitated 1 Click Defi
DZap promises to simplify complex DeFi transactions into a single flow — but my actual experience revealed both its strengths and its UX gaps.
A multistep Cross-Chain Transaction executed using just One Defi Mega Aggregator – DZap
I tried DZAP for a cross-chain DeFi transaction — transferring 0.0099954 WETH from BSC to receive Aave WETH (aOptWETH) on Optimism.
This is a complex transaction where multiple steps are executed, even though the user initiates it as a single flow.
The process involved:
• Swapping WETH → USDC
• Bridging USDC from BSC → Optimism
• Converting USDC → aOptWETH (deposit into Aave V3)
Map of DZap Transaction Execution Strategy Flow
During routing, multiple internal swaps occurred. For example, USDC was routed via intermediate assets like wstETH before finally converting to aOptWETH.
Multiple routing processes with wstETH in the routing flow
In the end, I received 0.009967 aOptWETH, visible in my wallet. This is yield-bearing Aave V3 WETH (~0.95% APY).

How DZAP Executes Multi-Step DeFi Transactions
DZAP is a mega aggregator protocol integrated with 100+ protocols across chains — including AMMs, bridges, and yield platforms.
DZAP’s algorithm evaluates the best AMM Pool, bridge, yield farming protocol to use – based on metrics of liquidity, fee cost so transaction execution processes execute efficiently – with less slippage, at lesser fee cost at a lucrative rate for the user, additionally benefiting users with DZap depositing asset in a yield bearing vault.
Execution Processes are synchronised by DZap in a “ZAP” style:
• Routing assets through pools with best liquidity (minimizing slippage)
• Select efficient cross-chain bridge paths
• Deposits into yield-bearing vaults
Costs incurred executing my DZap Transaction
My transaction that got successfully summited for execution by DZap
My transaction incurred small gas fees in form of BNB in BSC and ETH in Optimism charged for Blockchain usage. Apart from this – I receive 0.009967 aOptWETH, slightly lower than the 0.0099954 WETH sent.
This difference reflects execution costs, including:
• Swap fees (paid to liquidity providers)
• Bridge and routing costs
• Slippage
Therefore, DZAP backend execution was efficient and cost-effective.
Note – Rough estimate of fee and transaction execution costs procured evaluating – transaction records in Block Explorer and noting the difference between amount sent and received.
DZap Advantage
Using DZap simplified a process that would otherwise require:
• Manual swaps
• Separate bridge usage
• Interacting with multiple dApps
• Final deposit into Aave
DZap abstracts:
• Liquidity routing
• Cross-chain execution
• Multi-step transaction handling
👉 This reduces effort significantly for users.
Where DZap UX Needs Improvement
Despite strong execution, the user experience has gaps:
1. Not Truly “One-Click”
Initiating the transaction required:
• Token approval (spend permission)
• Execution approval
These are standard for MetaMask, but not clearly communicated.
👉 This caused confusion during interaction.
2. First Transaction Attempt – No Clear Record
My first attempt did not go through.
Metamask warns that the transaction is likely to fail
• I approved spending
• Then a second approval was requested
• MetaMask warned the transaction was bound to fail
I had signed this transaction but a Metamask Notification informed that the transaction was cancelled by DZap to avoid spending fees on a failed transaction.
This was a cancelled transaction where execution was not initiated on-chain, which is why no transaction hash exists.
These 2 Wallet approvals visible on chain is of the second transaction that successfully got executed by DZap
There is no record of this transaction in DZap’s Transaction history.
However, I taken screen shot of the transaction flow –
DZAp’s UI pop up had displayed
“Transaction failed to complete. Funds returned.”
This is confusing – as failed transactions are ones submitted on-chain but not having got executed.
DZap should update records in Transaction history and display messages that accurately mirror what happened.
3. Weak Transaction Tracking
DZAP shows progress stages:
• Swap
• Bridge
• Deposit
However:
• Refreshing the page removes tracking
• Backend continues, but UI loses state
👉 This creates a “black box” experience.
4.Incomplete Transaction History
Only a part of the transaction processed by DZap is recorded!
Only part of the transaction is recorded:
• WETH → USDC
• USDC → Optimism
But:
• ❌ Final step (USDC → aOptWETH) is missing
👉 The transaction is marked “Completed” without full breakdown.
5. Delays in Execution
• Swap → quick
• Bridge → ~30–40 mins
• Final deposit → ~20 hours
👉 No clear explanation or status updates were provided.
6. No Fee Transparency
There is no fee breakdown provided.
To estimate cost:
• I had to compare sent vs received amounts
• Use blockchain explorers
👉 Not practical for most users.
Summary of my experience using DZap
I first received 8 points for DZap usage with Transaction History conveying that my WETH was swapped to USDC and was bridged to Optimism. There were no further updates.
I opened a support Ticket to ascertain complete details of transaction progress as USDC was not converted to aOptWETH and visible my wallet.
Next day I open DZap with a Pop up displaying that transaction got completed successfully with my Metamask having received aOptWETH funds.
Transaction History was not updated with particulars of this latest processed transaction. However my DZap usage points increased to 16.
I felt relief that the transaction was processed and my funds were visible in the wallet, but this huge delay without updates caused me confusion and frustration earlier.
Final Thoughts
DZAP successfully abstracts complex DeFi operations into a single user flow.
However, the UX layer does not match the sophistication of its backend execution.
Key improvements needed:
• Clear communication of required wallet approvals
• Accurate transaction history (including aborted attempts)
• Persistent tracking across refresh
• Fee transparency
👉 The protocol works well — but user visibility and clarity need improvement
Improving these UX elements would significantly enhance user trust and make DZAP more accessible to a wider audience.
