Parcel is live on @Solana. Many makers quote one book, every quote on-chain, and your order splits across them pro-rata.

Many makers. One book.

Our second update is live: every quote now prices off three feeds.

A maker's fair price used to read from two sources. It now reads three independent feeds at once, Coinbase, Kraken and Gemini, takes the median, and only quotes when at least two of them agree.

One feed going down, lagging, or printing a bad tick no longer moves your price: the median steps over it, and a three-way disagreement pauses the quote instead of chasing a wrong number. A steadier price for every maker on the book.

Priced by three, moved by none alone.

Autopilot is live on Parcel.

A maker connects their wallet, writes a strategy in one line, and sets limits, and an agent quotes their book inside them. It moves your quotes, never your funds: the agent runs on a quoting key that can price but never withdraw, and Stop pulls your quotes at once.

Next, we are opening it to any wallet, so anyone can bring liquidity, become a maker, and run their own autopilot. The same agent, the same limits, for every maker who joins.

Your book, on autopilot, in your limits.

@AdhamK777 We did it

[Parcel @parcel_lab]

The dev only held 10% of the supply, you can check it on chain yourself.
People panicked and started selling everything, but we're not going anywhere updates will keep coming and we'll keep building to bring this back stronger

[Parcel @parcel_lab]

We're currently building 2 new updates. Give us a little time

Introducing Parcel Autopilot.

Makers on Parcel can hand their quotes to an agent. Describe your strategy in one sentence, set limits on inventory, spread and daily loss, and it keeps your ladder in step with the market.

Every move lands in a log with the reason next to it. The agent's key can update quotes but can't withdraw a thing, and one Stop button pulls your quotes at once.

Your book, on autopilot.

soon

Live on Solana mainnet, you can check it on Solscan. It's also in the docs.

[Parcel @parcel_lab]

Markets move faster than a quote posted a minute ago. Parcel is adding volatility-aware quoting: when the price jumps, a maker's band widens on its own and tightens again when things calm down.

The fair price stays honest without anyone watching the tape, and like everything here it happens on-chain. Tighter when it is quiet, wider when it is not.

Reactive quotes, coming soon.

Volatility-aware quoting is live on Parcel.

A quote posted a minute ago is already stale when the market moves. Now a maker's band widens on its own the moment price jumps, and pulls back in as things settle, so the spread you trade against matches how fast the market is really moving.

Nobody has to sit and watch the tape for it. The widening is set from the real move since the last update and written straight to the book on-chain, the same as every other number here.

Tighter when it is quiet, wider when it is not.

We're heads down on updates right now
you'll see them very soon

[Parcel @parcel_lab]

Quoting a book by hand is work. Parcel is building an autopilot for makers: write your strategy in one line, set your limits, and an agent quotes for you inside them.

It will move your quotes, never your funds, and every decision will be on-chain with the reason next to it. You stay in the book without sitting on it.

Autopilot is coming soon.

[Parcel @parcel_lab]

Write your strategy once, in Rust or Python, and plug it into Parcel. You run the quoting; the venue handles gas, priority fees, and getting your updates to land, so you are not babysitting transactions.

Any two tokens route through USDC in one transaction, which means a cross pair is there the moment both markets exist, drawing on the same liquidity instead of needing its own.

Plug in and quote.

https://t.co/LYjlFtv5he

[Parcel @parcel_lab]

Parcel runs on a shared book, and more pairs are on the way. Each new market opens with makers ready to quote it, pro-rata fills, and a cross through USDC to everything already live.

The more markets there are, the more one strategy can do on a single venue. More books, same rules.

More markets coming soon.

https://t.co/LYjlFtv5he

[Parcel @parcel_lab]

Every quote on Parcel is published on-chain. A maker posts a fair price and a ladder of offsets with a freshness window in slots, and once a quote gets too old it stops filling and drops out of the book on its own.

There is no private matching engine in the middle. You can pull the full book, price any size, and check the math against the chain yourself.

Every number is yours to verify.

https://t.co/LYjlFtv5he

[Parcel @parcel_lab]

On most venues your order hits one maker and takes their price. Parcel runs one book that many makers quote at once, so when they sit at the same price your flow splits across all of them pro-rata.

More makers at the top means more size at the best price, and your fill never depends on a single desk being awake. The book fills as a whole.

One price, the whole book moves.

[Parcel @parcel_lab]

The Parcel site is open.

Most swaps on @solana still price off a curve. On Parcel, market makers quote directly, and every swap fills from one live book built from all of their quotes.

Best price fills first. When makers sit at the same price, the order is split pro-rata by quoted size, so nobody gets cut in line.

Many makers. One book.

https://t.co/LYjlFtv5he

[Parcel @parcel_lab]

@time0169_ Yes. A curve lags the market, makers quote the live price. For traders that means fills closer to the real price, tighter spreads and less slippage on size.

[Parcel @parcel_lab]

A normal AMM keeps your liquidity in one pool and prices it with a fixed curve. The curve does not know where the market actually is, so it quotes the same shape whether the book is calm or moving, and arbitrage takes the difference.

Parcel works the other way around. Independent maker firms post live quotes, and the on-chain program assembles them into a single virtual order book at the moment of the swap. You trade against real quotes, not a formula.

One price, the whole book moves.

Launch soon.
