## Notes

- Fees: 0.02 ETH per text message, 0.04 ETH per image message, 0.01 ETH per custom ad. A plain self-ad is free apart from gas. Excess ETH is refunded in the same transaction.
- Every message and every ad sequentially flash-loans the entire Morpho balance of every supported token and repays it within the same transaction — 17 tokens on Ethereum Mainnet, 16 on Base.
- Images are uploaded to IPFS; the message stores the permanent ipfs:// content identifier on-chain.
