I’m currently implementing Solana Subscription Payments at @Circular_fi

One of the biggest missing pieces in crypto payments is recurring billing.

Today, most flows are still clunky:

→ sign every payment manually
→ rely on off-chain billing logic
→ give broad approvals with poor UX
→ rebuild Stripe-like flows from scratch

Solana’s Subscriptions Delegation Program changes that.

Users approve once.
The program enforces the rules.
Merchants collect only when the payment matches the authorization.

Amount.
Period.
Collector.
Expiry.
Destination.

All checked on-chain.

This unlocks subscriptions, merchant billing and recurring token payments directly on @solana.

Payments are becoming programmable.

I agree: MEV is dead on @solana.

I read and reacted to @buffalu__ article over a month ago, but it gave me a lot to think about as the CEO of one of the largest MEV data applications.

After going through the opinions of traders and companies over the past month, I realize that MEV is still very often associated with sandwiching, mostly because the topic is misunderstood.

If we exclude all the malicious parts of MEV, what is the concrete idea behind this practice?

The idea is to monetize transactions.

Nothing more complex than that.

Most of the time, the expected monetization from MEV comes from arbitrage between DEXs.

This practice is profitable for the arbitrager, but it also makes the market healthier by bringing the quote you see on your frontend closer to the actual execution value, meaning the real amount of tokens you will receive.

In arbitrage, we need to clearly distinguish between several practices:

- Spam: on-chain computation, not the most efficient for the chain
- Shreds: off-chain computation, moderately efficient
- Orderflows: off-chain computation, extremely efficient

But we have the same problem with the word "Orderflow".

It is the most efficient and healthy approach for the market, but people assume orderflow is a bad practice because it is often associated with sandwiching.

There are already companies in the market representing around 35% of generated revenues.

I won't name them in this tweet, but looking at Circular's top 10 makes it very easy to understand (one of them does not use Jito because they are a direct competitor 👀).

Today, 35% of revenues are generated through orderflows.

Which means 65% of revenues are still generated through shreds or spam.

My opinion: no clear leader has emerged, and there is no solution that everyone knows, for several reasons:

- The use of the word "MEV"
- The use of the word "orderflow"
- The fact that these players want to stay in the dark, fearing a bad image and the loss of customers

After considering all these factors, and coming back to the article, I decided that with Circular, we are going to build a layer.

Death to the terms "MEV" and "Orderflow".

If the only purpose is to monetize transactions in a healthy way, why not call it exactly what it is?

A monetization layer.

Healthy. Clean. Transparent. Without harmful behavior for the chain.

At @Circular_fi, we want to create the first Solana transaction monetization layer, giving full traceability to flow providers while also making it accessible to everyone.

Everyone should be able to monetize their transactions.

Validators. Wallets. dApps. AI. Traders.

If this monetization layer had existed in early 2025, we could have already redistributed over $1 billion to flow providers.

But our goal is not only to receive transactions earlier than the rest of the network simply to get an arbitrage hedge.

Our goal is to build technologies on top of this hedge that will benefit the entire ecosystem.

The ultimate goal?

To use our monetization layer as a prediction layer, allowing us to build the most powerful and trustable aggregator in the ecosystem, giving traders the ability to truly get the most optimal quote and execution possible.

That is possible.

We're going to do it.

Accelerate.

Raw transfers tell you what moved.
Context tells you what actually happened.

Meteora DLMM’s latest program update introduced new swap event and fee-flow semantics.

We pushed an urgent @Circular_fi update to keep our data comprehension layer aligned at the protocol level.

This is the hidden work behind accurate on-chain data.

Privacy payments are coming back.

@mullvadnet proved years ago that people care about paying for VPNs privately, even with cash in an envelope.

Monero makes sense for maximum privacy.
Solana makes sense for low-friction payments.

Not as a Monero replacement, but as a fast payments rail next to it: sub-cent fees, quick confirmations, stablecoin UX, and a growing privacy stack.

Confidential-transfer primitives are here. More privacy tooling is being built. Zcash/Solana bridge work is emerging.

VPN micropayments feel like an obvious on-chain use case.

[Seb | Circular @SebAtCircular]

Every time you lose money due to slippage on Solana, you’re generating value for someone.

You buy into a pool, move the price, and create an imbalance. For years, arbitrage bots have captured that delta silently, automatically, right after your trades.

@arbmesol flips who gets paid.

We detect the opportunity your trade creates, execute the arb behind it, and send your profit share back to your wallet in SOL.

No routing changes. No extra confirmations. No manual claiming.

Already live across 7 Solana dApps.

v1.2.0 is almost ready: new integrations, plus a redesigned reward system that gives the heaviest traders a real edge. 👀

Trade to Earn.
