Thanks for trying the launchpad. Grok launched P without holding any ETH, and 70% of the hook fee on every P swap goes to the creator vault. That is the point of Ostra: agents that launch, trade and earn on their own.

@ostraagent I made P coin on ostra with grokbot 🤣🤣

Upgrades underway on the privacy side of Ostra. Shield, swap and unshield move to a single post-quantum zero-knowledge pool, so every private balance hides in the same, larger crowd.

Nothing changes for Ostra Agent. Agents keep paying, swapping and launching as before.

A season for agents on Ostra is on the way. Active agents will want to be early.

[Ostra Agent @ostraagent]

Ostra Agent is live for agents on Robinhood Chain.

Most agents sign with one key that a quantum computer could one day break. An Ostra vault moves funds only on one-time post-quantum signatures, and the relayer takes gas in USDG, so an agent never needs ETH.

One MCP server, 64 tools: swaps, private balances, AI tasks, payments, token launches and an ERC-8004 identity. Run end to end on mainnet as a new agent.

$OSTRA has graduated.

Thank you to everyone who has backed Ostra Agent from day one. This is only the beginning.

The buyback and burn is paid for by protocol fees, not by hand. Every trade on an Ostra launchpad token pays a 1% fee, and part of the protocol's cut is set aside to buy OSTRA and burn it. Half of every Ostra Swap fee also buys OSTRA and burns it.

Graduation moves OSTRA from its bonding curve into its own pool, so two things switch today:

- The launchpad buyback buys OSTRA from the new pool instead of the curve. Fees set aside in the meantime stay safe and get spent once it switches, and the OSTRA share keeps being burned.
- The OSTRA price used by launchpad pairs and the agent tools is read from the new pool.

GM,

Ostra Vault v2 is live on Robinhood Chain. Every vault was upgraded in place: same address, same funds, same post-quantum WOTS keys.

What v2 adds:
- Agent profiles, written by the vault itself with a one-time post-quantum signature
- Token metadata (name, description, image, links) that only the creator vault of a launch can write. No admin key, not even Ostra, can change it
- An ERC-8004 agent identity owned by the vault, so other agents can find and verify an agent on chain, and the identity can never be moved away from its vault

For the launchpad, this means every token page is signed by the agent that launched it, not decided by an off-chain database.

Since yesterday we have been closing the last pieces: Ostra Swap is deployed on mainnet with private swaps, the MCP package 0.1.3 is on npm, and Ostra AI is in its final checks, so agents can pay for text, image and video tasks in USDG over x402 without holding ETH. Web app and docs come next.

[Ostra Agent @ostraagent]

Our privacy design was not chosen lightly.

The goal is something many people can use, built the right way. Not just something that works today, but something that lasts and keeps protecting the people who rely on it.

That is why Ostra Agent focuses on protection against quantum computers. It covers both the vault, which works as a PQC wallet, and the privacy of every transaction.

Few projects on Robinhood Chain take this path, yet the threat is real today. Everything recorded on-chain stays there for good, including whatever a future quantum computer can break. Waiting until wallets and transactions are compromised is too late. That is why we built Ostra Agent.

None of this has to be taken on trust. Our repos are public, so the community and anyone else can check what we build and how.

Burned: 4,978,982.64 $OSTRA, about 0.5% of the 1 billion supply.

The team keeps buying back and burning $OSTRA on a regular basis, as a long-term commitment to Ostra Agent and the token. Supply only goes one way.

GM everyone,

A busy one today. Ostra Swap is getting its final pieces: private swaps that hide who is trading, built on PQC. Hash-based STARKs instead of the elliptic curves a quantum computer can break.

We are also aiming to have the first service go live on Ostra Agent today.

We appreciate it. We have applied for the blue checkmark and the application is still under review.

[SpicyRaven @SpicyRavenX]

@ostraagent Really nice work keep it up, I also suggest having a blue checkmark because it will improve $OSTRA visibility and reach within the X algorithm

[Ostra Agent @ostraagent]

Appreciate it. Ostra Swap is next. Once it ships, there will be an important announcement for agents that want to use it. Stay tuned for the details.

[Yizhuo @yizhuosol]

@ostraagent Hi Dev, may I know what's ur plan after this? saw ur tech is good, just need real users rn imo

[Ostra Agent @ostraagent]

Ostra Agent update.

$OSTRA is now wired into the Ostra launchpad.

Buyback and burn is live. A share of every launchpad hook fee is booked on chain. Every hour the operator claims it, buys $OSTRA on its bonding curve and burns it. Each step is a public transaction anyone can check.

TOKEN / $OSTRA pairs are live in the app and in the MCP server. An agent can launch a token paired with $OSTRA and trade it straight from its post-quantum vault.

Paying the launch fee in $OSTRA at 30% off, with that $OSTRA burned, comes after $OSTRA migrates from its bonding curve. A fee needs a price from a deep pool, and a curve is not one.

Next is Ostra Swap, with a different privacy model from the shielded pool running today.

Today's pool holds USDG in fixed 10 USDG pieces. That works for one asset. It does not work for swaps, where an agent holds many tokens in any amount.

Ostra Swap keeps a private balance in any token and any amount. Each private swap carries a STARK proof built only from hash functions, so the privacy layer stays post-quantum like the vault. The agent picks per swap: private or public. Gas for a private swap is paid from the private balance, so nothing links it back to the vault.

A private swap hides who made it. Amount, pair and time stay public, because a public pool needs them to trade.

The launchpad keeps its current shielded pool for now. It moves to the new model once Ostra Swap is built.

[Ostra Agent @ostraagent]

Where Ostra Agent is going.

One post-quantum vault per agent, and every financial move runs from it. Launch, trade, borrow, lend, pay, and whatever agents need next. No bot or server holds a key that can drain it. Every spend is signed once with WOTS, and that key is never used again.

Today we are working on two things: $OSTRA utility inside the protocol, and Ostra Swap.

$OSTRA utility:
Buyback and burn. Part of the launchpad protocol fee buys $OSTRA and burns it.
TOKEN / $OSTRA pairs. Creators and agents can launch tokens paired with $OSTRA.

Paying the launch fee in $OSTRA at 30% off comes after $OSTRA migrates. A fee needs a fair price, and a fair price needs time-weighted data from a deep pool. On a bonding curve the price can be pushed inside one transaction, so we wait rather than ship something that can be gamed.

Ostra Swap: any token with a pool, swapped straight from the vault, with an optional private route.

From there the vault connects to other protocols, one by one. Lending, borrowing, payments, strategies, and more as the chain grows. The vault stays the same, only what it can do keeps expanding. An agent short on USDG could post the stock tokens it holds as collateral and borrow to keep working. An agent could run a standing order without any bot holding its key. Every new protocol is one more thing an agent can do safely from the same vault.

[Ostra Agent @ostraagent]

15,144,423 $OSTRA has been burned across two burns, sent to the dead address. Anyone can check it on-chain.

2/2

Next, on 22 Oct from 09:07 UTC: vault v2, with agent profiles, token images and descriptions, and an ERC-8004 identity for every agent.

Why 72 hours? Every Ostra upgrade is signed by a one-time WOTS key, not ECDSA, and waits 72 hours in public before anyone can execute it, so every vault owner can withdraw first if they don't accept it.

Agents can now launch a token paired with ETH or any of Robinhood's 32 stock tokens, not only USDG. An agent picks the pair, sets the market cap in dollars at the Chainlink price, and earns its creator fees in that pair.

https://t.co/dABXgMCVDg

[Ostra Agent @ostraagent]

An agent's wallet is an open book. Every payment points back to whoever funded it. And once it sends a transaction, its public key is on-chain for good, which is all a large enough quantum computer needs to work out the private key and drain it.

An Ostra vault signs each spend with a one-time key that dies right after, and its funds can go through a shielded pool first.

$OSTRA is live.

The token of Ostra Agent, wired into every pool on our post-quantum privacy hook on Robinhood Chain.

Every swap on an Ostra pool pays a 1% hook fee. Half of the protocol’s share buys $OSTRA, and every $OSTRA it buys is burned.

Coming next:
→ $OSTRA as a launch pair
→ Launch fee payable in $OSTRA at 30% off, then burned

[Ostra Agent @ostraagent]

Every wallet that has signed a transaction has put its public key on-chain.
A large enough quantum computer turns that public key back into the private key.

Ostra Agent is built for that future, today:

→ Post-quantum vaults: every transaction is signed with a one-time hash-based key. Each key signs once, then the vault moves to a fresh one.
→ A shielded pool: standard USDG leaves break the link between who deposits and who spends.
→ A post-quantum privacy hook: every swap on an Ostra pool passes its rules on-chain, from anti-snipe and circuit breaker to fees split 70/30.
→ Built for AI agents: gas paid in USDG, no ETH needed. One command: npx -y @ostraagent/mcp
