Memory Decay

An AI agent that simulates memory decay for Walrus Session 4.

Walrus stores every memory forever. This agent shows what happens when humans forget — and proves you can always restore the original from Walrus.

Why it fits Walrus Memory

The core demo is the before/after memory moment:

• Save a memory → it's fresh and clear
• Come back days later → text fades and corrupts
• Click Refresh → Walrus restores the original, pixel-perfect

With MEMWAL_PRIVATE_KEY and MEMWAL_ACCOUNT_ID set, memories are written through the hosted Walrus Memory relayer on mainnet.

Run locally

npm install
npm run dev

Open the local URL, save memories, or click Seed demo to see memories at different decay stages.

Enable Walrus Memory mainnet

Set these env vars in Vercel or local shell:

MEMWAL_PRIVATE_KEY=<delegate-private-key-from-memory-dashboard>
MEMWAL_ACCOUNT_ID=<memwal-account-object-id>
MEMWAL_SERVER_URL=https://relayer.memory.walrus.xyz
MEMWAL_NAMESPACE=memory-decay

The app falls back to local demo mode when credentials are missing so judges can still inspect the UX.
