Hypothetical Downside Scenario Analysis

"Realistic scenario downside on $1,000: $120 in a default bad-debt event. Net yield vs. standard bank deposit: +$90/year."

Safety status: Moderate Borrowing Shift. Potential bad-debt event in secondary collateral assets on Moonwell. This represents a robust risk-to-yield ratio.

PROJECTED RETURN SIMULATION

Balanced Strategy

Focuses on higher average yields by suggesting stablecoin allocation splits between conservative anchors and high-liquidity lending hubs like Moonwell and Fluid.

*Yield estimates are for informational purposes only. The assistant drafts all transactions, but they are signed manually with your secure hardware passkey.

SECTION 01 — THE PROBLEM

DeFi pays more. Most people can't access it.

Stablecoins sitting in savings accounts earn 0.5%. The same dollar deployed on Base blockchain earns 4–40% APY — verified, on-chain, every single day.

The gap isn't knowledge. It's structural infrastructure. Running a serious DeFi strategy requires:

Programmable Wallet

Requires ERC-4337 smart-contract capabilities to bundle operations efficiently.

Real-time Tracking

Hourly monitoring of yields across pools to capture peaks and bypass drop-offs.

Robust Risk Assessment

Evaluating lock solvency caps, bad debt ratios, and dynamic collateral levels.

Tx Construction

Crafting exact batch smart contracts and routing scripts to save on execution gas.

"Everything is automated. The agent drafts transactions, you verify and sign."

APY COMPARE

Compound Rate Spread

Comparing traditional dollars vs Base positions.

Traditional Bank Account0.5% APY
AI Selection Typical Rate4.41% – 25% APY
Target Delta Result

Every $1,000 sitting in standard savings earns roughly $5 annually. Deployed actively on Base, that same dollar compiles up to $250 in expected yield.

SECTION 02 — HOW IT WORKS

Smart DeFi automation. Analyzed by AI. Controlled by you.

The platform facilitates transaction automation on your Base Account — Coinbase's smart passkey wallet wrapper. The agent only prepares transaction drafts; keys are never shared.

This simulator runs directly in safety sandbox. It portrays the real-time interaction between the strategy scanning models and your secure Coinbase Smart Account.

01 / ACCOUNT SETUP

Open a Base Account

Takes just 2 minutes. Powered entirely by Coinbase's smart passkey wallet backend underneath.

02 / STABLECOIN DEPOSIT

Fund account with USDC

Fund with the leading fully-backed, US-regulated stablecoin pegged 1:1 to the US dollar.

03 / CONTINUOUS SCANS

AI daily opportunity sweeps

The MCP bot scans across 6+ protocols (Morpho, Moonwell, Fluid, Aerodrome, Avantis) hourly for yield-risk metrics.

04 / MEMO ANALYSIS

Transaction preparation

The agent drafts a transaction sheet detailing gas metrics, slippage margins, and risk bounds.

05 / USER SIGNATURE

Biometric signature

You review the prepared transaction draft and sign it locally using your secure hardware passkey (FaceID or TouchID).

06 / EARN YIELD

On-chain execution

Once signed, the transaction is broadcast to the Base network. Returns accrue directly in your self-custody wallet.

Self-custody proof: You physically sign every transaction on the blockchain. Base Yield Agent has zero access to your funds and cannot act without your signature.
SECTION 03 — THE TECHNOLOGY

Built on the same stack as the world's top DeFi funds.

SECTION 04 — STRATEGY UNIVERSE

One wallet. Six protocols. DeFi automation on Base.

The assistant scans live markets. You can allocate capital across conservative deposits and active liquidity pools based on AI-prepared recommendations.

Safety Safeguards

AI Safety Safeguards

Zero Leverage or Borrowing

The agent never prepares borrowing actions or leverage setups.

No Meme Tokens & Hype Contracts

The assistant strictly interacts with established stablecoin-denominated smart vaults with clean histories.

No Blind Entry into Extreme APYs

Dynamic positions with high annual yield are scanned rigorously for collateral backing before capital entry.

Zero Illiquid Lockups

Your USDC stays highly accessible, so you can exit when times are volatile or when you need fast liquid cash.

SECTION 05 — SOVEREIGN SAVINGS

Built for people who've decided their money belongs to them — not their bank.

You don't need to distrust the traditional financial system to be here. But if you do — you're in the right place. The platform is built on a simple conviction: the safest place for savings is where no intermediary can reach them.

Unpredictable Local Systems

Watched banks freeze accounts, currencies devalue overnight, and capital restrictions appear? DeFi automation offers an alternative path.

Financial Sovereignty

Your dollars should compile for you, not sit inside institutions that block, inflate, or compromise them at whim.

Borderless DeFi Yield

Real yields generated directly by market liquidity demands, settled by decentralized rules instead of SWIFT bans.

Zero Added Complexity

You do not need to become an active DeFi wizard. The assistant drafts secure transaction calls while you keep 100% custody keys.

Comparison: Traditional Finance vs Self-Custody Automation

AUDITING PROTOCOLS

Pre-trade compliance check

Before presenting any allocation rebalance recommendation, or signing transactions, the system validates every metrics node.

SAFETY SIGNAL STATUS: SYSTEM SECURE (3/6 CHECKS ACTIVE)
SYSTEM SAFEGUARDS

Tapping into institutional rigor

Tiered risk bounds

Conservative strategies stay active as your root defaults. Dynamic high-yield vaults require explicit approved credentials.

Gas Buffer requirement

Maintaining small reserve gas quantities of Ethereum (ETH) in the wallet is recommended to confirm withdrawals whenever conditions turn hostile.

No autonomous transactions

The AI scans conditions and prepares transaction drafts, but only your physical TouchID/FaceID signature commits operations to the blockchain.

*No geographic restrictions apply. No audits are conducted on user intentions. This is a core priority of self-custody. Capital efficacy remains standard.
SECTION 06 — TRANSPARENCY

Every number is verifiable. On-chain. By anyone.

Unlike opaque traditional offshore funds, all data is transparent here. Every ledger update can be cross-audited on-chain via public network browsers.

01

BaseScan browser integration

Every compounding event, allocation movement, and rebalance can be checked by searching your account address on basescan.org.

02

Direct Protocol verification links

Your exact positions can be audited anytime by connecting your ledger keys to morpho.org or moonwell.fi dashboards.

SECTION 07 — STRATEGY SELECTIONS

Data-driven analysis. Prepared by AI. Signed by you.

Daily Sweeps

The smart scheduler pulls APYs across all protocols, flagging positions where yield drops or utilization spikes.

Scoring Weights

Candidate pools are graded on expected net APY, TVL buffers, collateral assets quality, target liquidity depth, and gas expenses.

Migration Threshold Bounds

Rebalances are strictly locked unless expected extra returns coverage transaction gas bounds in under 3 months.

AI THRESHOLD PARSER EXAMPLE
Rebalance Candidate:Morpho → Moonwell USDC
Expected APY Gain:+4.82% Annual
Estimated Total Gas:0.0001 ETH ($0.003 USDC)
Threshold Status:THRESHOLD PASSED
The agent prepares a transaction draft and risk assessment. The user independently decides whether to sign, edit, or reject.
SECTION 08 — ACCOUNT OWNERSHIP

You keep your account. The agent only prepares transactions.

This is not a pooled fund or discretionary account management. You never send funds to third parties. Your stablecoins stay situated inside your self-custody Smart Account (ERC-4337) under your absolute control.

WHAT YOU CONTROL
  • 100% custody of keys
  • Instant penalty-free withdrawals
  • Approve or reject allocations
WHAT THE AGENT PREPARES
  • Daily opportunity monitoring
  • Transaction drafts with gas and risk assessments
  • Operation logs formatted for your reporting

Dynamic Exit limits:Unlimited Instant
SECTION 09 — ACCRUED FAQ

Frequently Answered Questions

Complete clarity is the priority. If you have additional inquiries, connect inside on-chain discussion channels.

Your funds remain in your Base Account — a smart contract wallet (ERC-4337) utilizing Coinbase Smart Wallet infrastructure. Direct custody of funds by any third party is completely excluded. Every transaction, allocation shift, or withdrawal requires your explicit cryptographically signed approval.
You can withdraw at any time. There are no lockups, and you hold the keys. Morpho and Moonwell withdrawals typically process within minutes back to your main wallet. During rare high-utilization periods on certain lending markets, it could take a bit longer, which is why maintaining a liquid margin is recommended.
The underlying DeFi protocols (such as Morpho and Moonwell) charge natural raw performance fees (0–15%) on yield, which is already deducted from the APY figures shown. The platform interface charges a modest fee only on yield successfully generated.
Each tier represents a different risk level. Conservative tiers (Aave, Morpho Prime) have virtually zero liquidation threat; the main risk is systemic smart contract exploits. Elevated and Active tiers (such as Avantis and Aerodrome) involve dynamic liquidity variables, liquidity lock variations, and market trading results. The assistant dashboard prepares realistic dollar downside estimates before every recommendation so you can make informed decisions.
Not at all. You only need a Coinbase Wallet or compatible smart wallet app. The assistant dashboard prepares the transaction drafts, performs checks, and simplifies the technical workflow; you just sign recommendations with FaceID/TouchID.
Automated, detailed tax event tracking is built in. Every deposit, yield payout, rebalance, and on-chain fee is captured in an elegant, structured format that is ready to download and share with your CPA at the end of the year.
