OPN DeFi Safety Dashboard
Prevent unsafe OPN Chain actions before users sign.
Wallet readiness, OPN RPC health, calldata inspection, approval risk detection, token allowlists, read-only market signals, and user feedback in one focused interface.
Safety promise
Read-only by default. No seed phrases, no custody, no hidden approvals, and no real swap execution until verified routing and simulation exist.
OPN integration
Live RPC health, Chain ID 984 wallet checks, tx/address lookup, explorer-ready architecture.
Technical quality
Typed API routes, deterministic risk engine, safe read-only defaults.
Product and UX
Wallet readiness score, transaction inspector, mobile controls, feedback triage.
Innovation
Intent receipts, protocol trust scoring, recovery playbooks, and DeFi blind-spot mapping.
Commitment
Roadmap, feedback loop, and measurable next milestones.
Reviewer evidence snapshot
The shortest path from the judging rubric to working product evidence.
Live OPN usage
Chain ID 984, RPC health, block/gas/latency, wallet network validation, balance reading.
On-chain verification
Transaction/address lookup through OPN RPC, explorer links, and deployed proof contract.
User value
Risk score, wallet readiness, approval hygiene, bridge/LP/yield labs, feedback triage, and recovery guidance.
Execution boundary
No custody, seed phrases, hidden approvals, or real token movement until routing and simulation are verified.
Rubric coverage map
A reviewer-facing map from the official rubric to visible product evidence.
OPN Chain integration
30%Live Chain ID 984 RPC, wallet network checks, native OPN balance, tx/address lookup, explorer links, deployed proof contract.
Technical quality
25%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.

Security model
Professional DeFi UX starts by preventing unsafe actions by default.

Amount
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

Intent firewall
A personal policy layer missing from most DeFi UIs: block actions before the wallet popup.
Action type
Action size
Max policy
Max slippage
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
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
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.
