Next.js App Router, typed API routes, deterministic risk engine, safe fallbacks, Netlify dependency shim, locked execution.

Product and UX

20%

Single cockpit flow, mobile-friendly controls, clear safety states, feedback triage, readable risk findings.

Innovation

15%

Intent firewall, intent receipt, protocol trust score, recovery playbook, bridge/LP/yield blind-spot coverage.

Creator commitment

10%

No paid dependencies, roadmap, reviewer proof pack, safe MVP scope, clear path to real simulation and audited modules.

All five scoring categories have visible product evidence.

Real token movement remains locked by design until trusted OPN routing, allowance reading, bridge verification, and transaction simulation exist.

Reviewer proof pack

Direct evidence for the five scoring categories, visible inside the product.

OPN Chain integration

Native wallet connection, Chain ID 984 checks, live RPC health, block/gas latency, transaction hash lookup, address lookup, explorer links, and deployed on-chain proof.

Technical quality

Typed Next.js API routes, deterministic risk engine, read-only defaults, locked execution, graceful API fallbacks, and optional dependency shim for stable Netlify builds.

Product and UX

One workflow: connect wallet, inspect prompt, check chain health, review tokens, simulate swap, bridge/LP/yield risk, submit feedback, and use mobile-friendly controls.

Innovation

Intent firewall, pre-signing intent receipt, protocol trust score, post-signing recovery playbook, DeFi blind-spot map, and RWA safety boundary.

Creator commitment

Clear roadmap, feedback triage, no paid API dependency, no custody, no seed phrases, and a path from MVP to allowance reading, simulation, and audited protocol modules.

The product is intentionally read-only in this season build: it proves OPN usage, gives users useful safety checks, and avoids unsafe token movement until verified routing, allowance reading, and simulation are ready.

OPN proof and submission pack

Everything a reviewer needs to verify the build without guessing.

Feedback triage

Collect safety issues, data mistakes, and UX bugs.

Security model

Professional DeFi UX starts by preventing unsafe actions by default.

Block swaps when connected chain is not OPN Chain.
Block token actions without an allowlist entry.
Warn before unlimited approval, permit, and setApprovalForAll patterns.
Show testnet/mainnet state before signing.
Keep stocks and RWA data read-only until licensed data and verified contracts exist.

Bridge route is ready for simulation

Verify official bridge URL, recipient address, source chain, destination chain, final token, fees, and estimated arrival before signing.

Approval hygiene

Approval management playbook for future revoke and allowance integrations.

Unlimited approval

Critical

Avoid unless spender is verified and actively used.

Permit signature

High

Treat like token spending approval.

Router approval

Medium

Check spender address and revoke after use.

Read-only balance

Low

No token movement or approval requested.

Next milestone: read allowances from verified token contracts and show revoke links through trusted explorers/tools.

Intent firewall

USD

USD

%

Allowed by current policy

This action fits your current personal risk policy. Still inspect calldata before signing.

Post-signing recovery playbook

Most DeFi apps stop after execution; this tells users what to do after signing.

Action

Before signing: verify spender address and exact allowance.
After signing: save the transaction hash and monitor spender activity.
If suspicious: revoke allowance through a trusted allowance tool or explorer flow.
Long term: prefer exact approvals over unlimited approvals.

Pre-signing intent receipt

A user-readable receipt created before the wallet popup, so the final signature can be compared against intent.

Intent

Give asset

Receive asset

Max exposure

USD

Local receipt #A3E2FD10

OPN intent: Swap | give: OPN | receive: USDC | max exposure: 250 USD | counterparty: Verified OPN route

If the wallet popup asks for a different spender, token, chain, approval size, or action, reject and inspect again.

Protocol trust score

A due-diligence layer for protocols before they appear in swaps, bridges, pools, or yield modules.

Trust score

20/100

Do not integrate. Execution should remain locked until the missing controls are verified.

DeFi blind-spot map

The product angle: protect users in places large DeFi apps often leave to user judgment.

Personal policy firewall

Users set risk limits before wallet prompts appear.

After-action recovery

Every action has revoke, monitor, and escalation steps.

Intent receipt

Users compare the wallet popup against their own pre-signing intent.

Protocol trust score

Protocols must pass source, audit, admin, oracle, and disclosure checks before use.

Bridge recipient discipline

Bridge flows check recipient and destination before signing.

LP exit thinking

LP users see exit liquidity and impermanent loss as first-class risk.

RWA jurisdiction lock

Stock/RWA features remain read-only until data and contract legality are verified.

Plain-language signing

Every future transaction should explain what changes in the wallet.

Commitment roadmap

Clear next steps for turning the MVP into a durable OPN safety product.

May-June 2026: harden OPN RPC checks, improve inspector coverage, collect reviewer feedback.
July-September 2026: add trusted OPN quote previews, transaction simulation, and explorer-backed wallet activity.
October-December 2026: integrate audited OPN DeFi modules and licensed RWA data if validated.
