Gm and welcome to another lesson. 👽🤝🤖 This time it focuses on simplifying agentic interactions on @SonicLabs and how $USSD plays a role in these. ⬇️ Think of a crypto network as a city again. People live there, shops open, banks doing bank things and money moves. Agents are the workers who can walk around that city on their own. It’s a piece of software with its own wallet and can hold money, pay for things and follow rules you set, without you clicking “confirm” every time. Now imagine a small delivery service in that city. You tell your agent: “Every morning, if bread is under 1$, you buy two loaves and pay the bakery.” The agent checks the price, sends the payment (if bread is under 1$) and keeps the receipt. You do not open an app nor approve the transfer. It already has permission and its own money to use. That only works if three things exist: Wallet & permissions - A wallet the agent controls, so it can pay without using your password/seed each time. A reliable dollar stablecoin - If the agent is supposed to spend 1$, that dollar needs to still be 1$ when it reaches the bakery. - That is the home dollar job of something like $USSD on Sonic: Stable money, agents can hold and spend. A shared rulebook - The payment has to be final, visible and hard to fake, so the bakery trusts the agent and the agent trusts the bakery. The blockchain is that shared book. Ofc this pattern scales past bread. ⬇️ One agent can watch lending markets and move dollars to wherever the rate is better, inside limits you set. Another can test a new DeFi strategy and sends funds across different protocols. A third can collect interest from a tokenized asset and send your share to your wallet. In each case: The agent is the worker The stablecoin is the cash The chain is the city & rule book Spawn Studio and marketplace will be the workshop for these workers. Devs publish agent templates and users can pick one, fund it and set the rules for it. The agent then interacts with the network, pays and gets paid in dollars such as $USSD. Sonic‘s incredibly fast and nearly instant finality tech is a perfect fit for these agentic interactions. People use the city when they feel like it. Agents use the city on a schedule or the moment a condition is met, all automated. They need a home dollar so “pay 1$” still means 1$ and a public ledger, so everyone can see the job was done. Hope that makes it a little easier to understand. Until next time 👻 sonic-3:native

Gm and welcome to your today's lesson about @SonicLabs and @Frax little beibeeh called $USSD. A blockchain is a little bit like a digital city. You have shops, apps, infrastructure, banks, culture and markets and all of them need a simple dollar that always stays worth one dollar. Other dollars may visit and be used too, but the home dollar stays, gets used everywhere and helps with growing the city. The native (home) dollar in this case is $USSD. Since march 2026 it runs on the Frax (frxUSD) System which enabled Sonic to build its own secure and institutional-backed stablecoin on top of it. ⬇️ - It is backed by one dollar worth of short-term U.S. government debt (Treasury bills). Those reserves sit with regulated custodians and include products from big names like BlackRock, Superstate and WisdomTree. - You can create it by handing in common dollars such as USDC or USDT (or certain Treasury tokens) at a 1:1 rate, with no minting fee. You can turn it back into those dollars later. - You can start on more than 10 other blockchains and receive $USSD straight on Sonic. Fiat USD redemption exists, but requires KYC. - Apps on Sonic are meant to use it for trading, lending, and settling payments so the dollar liquidity stays in one place instead of leaking off the network. - Interest earned on the Treasury reserves is designed to flow back into Sonic. For example by buying the network’s sonic-3:native token or funding incentives. You may remember that @MattVisser was talking a lot about the four verticals recently: Payments and FX rails / AI / RWAs / Prediction markets Payments and FX rails: Sonic is pairing $USSD with partners (including Frax’s rails, Circle’s USDC, Spendl and Mastercard spending) so transfers can settle faster and cheaper. People can spend the digital dollar in the real world. A trusted local dollar is the piece that makes those payment rails work. RWAs: Tokenized Treasuries, funds or other real assets need a common dollar to borrow against or trade with. Products like Nummo use $USSD as that shared dollar so people can keep their yield, while still borrowing or moving value, with Sonic handling the settlement underneath. AI, Spawn Studio and the agentic economy: Spawn Studio is where developers build and publish templates for AI agents. Spawn Marketplace is where regular users pick one, fund it and send it off. Those agents will need to pay, hold value and settle on-chain. A steady dollar like $USSD is the money they can use, so they are not stuck in their operations. Prediction markets: A bet is just a payment with a score at the end. Someone has to hold the stake, pay the winner and move on. That works a lot smoother if the stake is a dollar that already lives natively on Sonic. In the end the catch is, which dollar stays. Other dollars can visit and Sonic ofc wants USDC too, e.g. for payments and card spending. But the interest on those reserves stays with Circle. $USSD is the home dollar. Same kind of Treasury backing, except the interest is designed to come back into the city, as sonic-3:native buybacks or incentives, instead of leaving the city. That only works if people mint it and leave it there. Using it once does not earn the bill yield. The balance that stays does. Payments, FX, RWAs, agents and markets all need a dollar that does not wander off. If those verticals settle in $USSD, the city keeps growing. If they settle in another dollar, Sonic gets the traffic and the issuer gets the income. Until next time frens 👻 sonic-3:native

Still not sure how to use arca Vaults on @SonicLabs, or you don’t know how it works? Actually, it couldn’t be easier than that. Give it a look 👇

Seoul, see you October 1. 🇰🇷 Sonic CEO @MattVisser joins HSC’26 to share where Sonic goes next, from the work underway today to the next phase of growth for the network. See you there.

11.21% on Liquid Alignment, our stS/wS pool. A dedicated stable pool optimised for LPing an LST against its base asset. Hard to beat on a risk-adjusted basis, and the staking yield keeps running underneath. beets.fi/pools/sonic/v3/0x75…
