MAJOR ANNOUNCEMENT

🎶 come on down, to epochtown 🎶

Announcing epochtown (pronounced ee-pak not ep-uck) a community for Solana builders, devs, artists, entrepreneurs and anyone else interested in building the future on Solana

As someone new to Solana it is sometimes hard to find like minded people to learn from, collaborate with and build with. Epochtown aims to change that, all newbies are welcome and no questions are too dumb to ask

If you’re just getting started, trying to find your way around, or want to find someone to collaborate with on the next hackathon, or maybe you’re building and have questions come on down!

Discord link in next tweet below

Huge huge huge thanks to @adlonymous for the discord magic, @jacobvcreech @nickfrosty for the motivation, @dhruvsol for the cute designs and @beeman_nl @metasal @0xnaga @SolDapper for being the OG fire starters :)

Most Solana teams optimize RPC.

We decided to remove it.

At @brewlabshq_ , our latency requirements pushed us beyond Yellowstone and toward consuming validator data directly from the source.

Today we're open-sourcing part of that work:

Qlaster — Shared-Memory Data Streaming for Colocated Solana Services.🧵

[ax @ax_1000x]

open sourced a draft we were exploring: onchain trading agents for solana.

the idea: users define private execution filters, such as oracle-price conditions for perps. a registered cranker can execute the trade instruction only when the agent is active, oracle data is fresh, the proof matches the committed filters and all protocol accounts validate.

current draft: authorized crankers.
possible next step: public filters/indicators/cranking, where users set a fee and anyone can execute through gated conditions.

@Ahyammona p cool, is this a sidecar? is it open source?

Does XDP work on my driver/NIC? maybe! probably! find out below 👇

[Canned Oxygen @canned_oxygen]

can your @solanamobile do this?

[ferric | stakeware.xyz validator (marketing arc) @ferric]

@ax_1000x plot twist I’m already on android

[ferric | stakeware.xyz validator (marketing arc) @ferric]

Wow. From 113gb down to 80gb

Amazing tek

[kevinn @ialwayskevinn]

IT WORKS!! Thank you to whoever shared this

1. Turn on airplane mode
2. Change the date manually to 2027
3. Leave your phone for 2 minutes and don’t open any other apps
4. Change the date back to today (put real time & date)
5. Off Airplane mode then check your storage again

[ferric | stakeware.xyz validator (marketing arc) @ferric]

@ax_1000x Zero effect so far, just got 33gb back like magic. I’m sure it’ll pile up again. 🤦🏾‍♂️

[mynamegreg.sol @GregoryCusack]

my sisters and brothers of christ. why are we going backwards in testnet xdp adoption? look at this chart. down is good. down is fast. down means more CUs. down means we're goated. down means we're rad as hell. just turn it on and we win forever.

[ax @ax_1000x]

what day is it?

me: epoch 976, slot 422032676

i no longer experience linear time

There need to be like 500+ on-ramps the current gatekeeping is worse than tradfi

Hard problem tho, lots of regulation

[Metasal aus/acc 🦘 @metasal]

i will work for free if u building this

The dark art of transaction landing in 4 steps

[nagaprasad.sol 🌌 @0xnaga]

@redacted_noah Few other tricks -

Mapping slot leaders perfectly

Using jito along with tpu to land txs (maybe also harmonic )

Writing super optimised code to avoid any internal latency

Placing senders near to leaders (lowering network latency)

[mynamegreg.sol @GregoryCusack]

before you leave for the long weekend (american), turn xdp on.

Have you ever heard about the inefficiency of AMMs? When you trade on-chain, you lose money.

As a daily Solana user, I make swaps every day.

Simpler, cheaper, faster.

But I have a crazy statistic to share with you: traders on Solana lost $1 billion in 2025 because of the math.

What does math have to do with any of this?

An AMM/liquidity pool operates, for the most part, without an order book but using math (x * y = k).

This mathematical formula is the core concept behind an AMM.

Let's take a simple example:

x = USDC
y = SOL

Market price of $SOL is $100.

If I deposit 1,000 USDC, I’ll also deposit 10 SOL so that my liquidity pool has a market price of $100 per SOL (1,000/10 = $100).

Now, let's do the calculation (x * y = k):

1,000 USDC (x)
*
10 SOL (y)
=
10,000 (k).

Great so we know the mathematical value our liquidity pool aims to achieve: 10,000.

Now let's make a trade of 250 USDC to exchange it for SOL… how much do you think you'll get back?

If the price is $100 per SOL, by exchanging 250 USDC you'll get 2.5 SOL, right?

Absolutely not!

Let's do the math again:

1,250 (1,000 initial USDC + 250 deposited by your trade)
*
7.5 (10 initial SOL - 2.5 withdrawn by your trade)
=
9,375.

9,375, not 10,000.

Whereas:

1,250 * 8 = 10,000.

So the liquidity pool will give you 2 SOL instead of 2.5 SOL.

You just lost 0.5 SOL.

This is what's known as AMM inefficiency.

Now the question is: how can you protect yourself from this?

Arbitrage.

You can recover the value you lost by arbitraging liquidity pools.

In this case, if I buy SOL from another liquidity pool and sell it on this one, I’ll rebalance it to 1,000 USDC – 10 SOL and capture the lost value (0.5 SOL).

It was by realizing this that we built @arbmesol for the @colosseum.

It's an extension that lets you recover the SOL you lose during your trades on Solana as cashback directly into your wallet.

Now that you know this and that a solution exists… you're the only one responsible for losing SOL due to the inefficiency of AMMs.

Trade to Earn.

Hot take SF is trash compared to Austin.

[ax @ax_1000x]

if you are a builder, whats stopping you from building on solana?

what would you change?

what tooling, docs, infra, support or incentives would make it easier for you to build on solana?
