Andrej Karpathy (co-founder of OpenAI, Eureka Labs): "Coding is no longer the skill. knowing how to direct agents is."
Yesterday, i used Hermes Agent to build an App that can send messages to specific wallets via the the blockchain.
Core Idea
It lets users post permanent, immutable public messages/notes tied to any Solana wallet address.
Think of it as a decentralized reputation system, public comments, warnings (e.g., scam alerts), or simple wallet-to-wallet communication.. all stored transparently on the blockchain.
Key Features
• Wallet-based identity
• Censorship-resistant and immutable messages.
• Low-cost, fast interactions thanks to Solana.
How It Works (Simple Flow)
1. Connect Wallet — Use Phantom/Solflare on the site.
2. Post Message — Write a note linked to a target wallet → sign a Solana transaction (via custom program/smart contract).
3. On-Chain Storage — SMS is recorded in Solana accounts (PDA). Small text fits directly on-chain; Solana’s high speed (~thousands TPS) and tiny fees (~$0.00025) make it practical.
4. View Messages — Anyone queries the program via RPC to see all notes for a wallet.
5. Token Role — SMS likely pays for posting or unlocks features (spam protection + revenue).
Tech Stack (Typical): React frontend + @ solana/web3.js, Rust/Anchor program on Solana, possible IPFS for larger data.
It’s lightweight, permanent, and leverages Solana’s Proof of History for fast, cheap, parallel processing.
sMessage (SMS) is basically the blockchain alternative to X’s irritating message request folder. It’s a signal app built on the Solana blockchain.

One of the biggest mistakes you can make in crypto is leaving your stablecoins idle
There are now multiple protocols on Solana offering ways to earn yield while maintaining exposure to stable assets.
If you're looking for places to park your capital, here are some protocols worth exploring:
1️⃣ @humafinance ( $PST ) - 10-18% APY
→ Huma is a PayFi protocol that provides liquidity for global payment companies, enabling faster settlements and access to working capital
2️⃣ @piggybank_fi ( $pbUSDC ) - 14.82% APY
→ Piggybank is a DeFi protocol that generates extra yield on top of digital assets (eg. stable-coins, tokenized stocks, cryptos...)
3️⃣ @onrefinance ( $ONyc ) - 11.87% APY
→ OnRe brings the reinsurance market onchain, allowing users to access returns from a traditionally institutional asset class.
4️⃣ @hylo_so ( $sHYUSD ) - 11.30% APY
→ Hylo is a stablecoin protocol focused on making yield-bearing dollars simple and accessible on Solana.
