TL;DR
- Present useful resource requests are poorly calibrated: consumed Value Items are solely ~20% of requested on combination; even transactions explicitly setting each limits overrequest by ~95k CU on common (p90 ~280k)
- The payment affect is broad and extremely workload-dependent: even assuming excellent useful resource pricing, solely ~28% of transactions see a payment enhance beneath 10%. Transfers are roughly unaffected/barely cheaper, whereas account creation, CLOB market making and particularly on-chain routing develop into dearer
- Buying and selling infrastructure is most uncovered: common payment enhance is ~0.000068 SOL for Jupiter, ~0.00010 for Titan and ~0.00012 for DFlow; increased prices additionally elevate the minimal worthwhile alpha for atomic arbitrage
- Validator economics change solely reasonably: optimized vote transactions develop into ~12.3% cheaper, whereas chief protocol-fee income is unchanged for single-signer transactions and falls for multisig site visitors; estimated common loss is ~0.00015 SOL/block
- The most important macro impact is increased SOL burn: estimates vary from ~6–8k SOL/epoch underneath 10% useful resource optimization, ~8–10k with present consumption and excellent requests, to ~30–35k underneath the p75 residual-mispricing state of affairs. These stay behavioral counterfactuals, not forecasts.

Introduction
SGP-0003 signify a radical develop into SOL tokenomics. The proposal need to make Solana’s base payment resources-aware. The brand new base payment is decomposed right into a flat payment plus a payment which scales with the quantity of assets a transaction requests.
The principle aim of this doc is to supply all knowledge wanted to make an knowledgeable determination. The aim is to not decide a facet, however make all implications seen.
Are Requested Useful resource Calibrated?
When the scheduler accepts a transaction, it reserves the requested price of that transaction. Solely after execution, as soon as price consumed are recognized, the surplus may be allotted once more to the block CU finances.
Regardless of that is already one thing to deal with when reasoning about useful resource miscalibration, there may be extra.
Transaction prioritization is outlined from payment paid per requested price. Because of this, an extra in CU request is definitely reducing the precedence of a transaction, making it troublesome to construct environment friendly blocks the place assets are priced accurately.
These two options offset to zero the good thing about v1 format, the place “worth of transaction” is understood ex-ante.
As of right this moment, the actual advantage of correctly pricing CU may be hidden by the lengthy wall-clock time of slots and their abundance of unused area. Sooner or later, this can be way more noticeable.
However at this level we have to have a look at present snapshot.
Determine 1 exhibits the Cumulative Distribution Perform of Value Unit extra (requested minus consumed) per transaction, the place transactions are grouped by the one with express CU and cargo knowledge dimension (gray line), express CU however no load knowledge dimension (pink line), express load knowledge however no CU (orange line), use default for each (blue line).
Fig.1: Distribution of Value Unit extra per transaction. Right here we show the CDF of Value Unit
extra (requested minus consumed) per transaction grouping txs that express CU and cargo knowledge dimension
(gray line), express CU however no load knowledge dimension (pink line), express load knowledge however no CU (orange
line), use default for each (blue line). The worth on y-axis represents the likelihood to discover a
tx with a Value Unit extra decrease than the worth on the x-axis. Determine exhibits how txs with no
express CU and cargo knowledge dimension are the one with the very best extra of Value Unit. Supply:
Dune.
It’s clear that transactions with no express CU or load knowledge dimension are the one displaying the very best extra of Value Unit requested.
By way of transactions topology, knowledge present:
- 48.6% of transactions explicitly set CU and loaded knowledge dimension restrict s
- 43% of transactions explicitly set CU restrict and use default loaded knowledge dimension restrict
- 8.4% of transactions use defaults limits for CU and loaded knowledge dimension limits
- there’s a tiny quantity of transactions, 10 out of two.4B scrutinized, which specify loaded knowledge dimension restrict however use default CU restrict.
Fig. 2: Abstract statistics of Value Unit extra for every transaction topology. Supply:
Dune.
Transactions that specify each CU and loaded knowledge dimension restrict see a median extra of ~95k, with a p90 of ~280k. If the surplus in request is because of unknown on modeling of wanted assets, this may price on common ~45000 lamports extra.
This isn’t a small enhance. Assessing if builders can truly transfer down extra in requests shouldn’t be trivial: we are able to’t estimate the results on every day operations.
Fig. 3: Fraction of Value Unit Consumed over Requested. Supply:
Dune.
Determine 3 exhibits that as of right this moment, Value Items actually consumed signify ~20% of Value Unit requested. This point out that there’s a big room for enchancment.
Affect on Transaction
At this level it’s necessary to look instantly at implications on transactions.
Right here, for the sake of simplicity, we are able to assume that Solana community strikes right into a effectively optimized regime and there’s no extra in requested price models.
Fig. 4: Distribution of the bottom payment enhance with SGP-0003. Right here we show the CDF of base payment
enhance expressed as share. The worth on y-axis represents the likelihood to discover a tx with
a p.c enhance on base payment decrease than the worth on the x-axis. Supply:
Dune.
If we condensate the worldwide snapshot underneath a CDF, we are able to see how transactions can expertise a cloth enhance put up SGP 0003 (assuming Value Unit will keep the identical). Solely ~28% of transactions will see a rise decrease than 10%.
This represents a significant barrier, and builders must assess implications for his or her operations.
At this level, we are able to’t actually look inside all transaction. Nevertheless, we are able to transfer ahead by breaking down implication for main classes.
Funds
Funds are coming on-chain, and Solana is extremely aggressive on this sector.
What’s the implication of this proposal on funds?
To reply this query, we verify the payment enhance for
- regular switch
- account creation.
The outcomes of distribution in SOL enhance is displayed in Fig. 5 and Fig. 6.
Fig. 5: Payment affect on Switch. Distribution of SOL enhance in base payment per transaction. Supply:
Dune.
Fig. 6: Payment affect on account creation. Distribution of SOL enhance in base payment per transaction.
Supply:
Dune.
Usually, transfers will see a discount in base payment. The majority of the distribution is round -0.0000017 SOL per transaction. This can be a tiny quantity, so the tl;dr is that common switch should not affected a lot.
The scenario is completely different for account creation. The majority of the distribution is round 0.00005 SOL per transaction. That is nonetheless materially decrease than the 0.0002 SOL in hire forecasted after hire discount is dwell.
propAMMs Market Making
One of many key improvements on Solana is the rising of propAMMs. These unlocked new functionalities, permitting Solana to be very aggressive with exterior venues on spot buying and selling.
To evaluate implications on propAMM operations, we gather all oracle updates and estimate the affect on base payment after SGP-0003.
Fig. 7: Distribution of base payment change after SGP-0003 for propAMMs’ oracle updates. Supply:
Dune.
Right here the affect shouldn’t be uniform amongst propAMMs.
We see that there are propAMMs like BisonFi, Tessera, HumidiFi, SolFi, GoonFi that can see a discount on base payment. Different, like Aquifer, will see the majority of the distribution round 0.000006 SOL enhance per transaction. ZeroFi exhibits a combined behaviour.
Normally, regardless of the rise for some propAMM appears small, a number of updates per slots could drastically enhance operations prices.
Nevertheless, nearly all of propAMMs’ oracle updates will lead to a decrease quantity of payment paid in base payment.
CLOBs Market Making
CLOBs are nonetheless one of the essential primitives when discussing market exercise. These require market makers to continuously replace their view of the guide.
To estimate the implications on CLOBs exercise, we tracked market maker orders on Archer, Phoenix DEX, and Phoenix Perp.
Fig. 8: Distribution of payment distinction put up SGP-0003 for market making exercise. Supply:
Dune.
What we see is a rise in market making exercise, with Phoenix DEX principally affected.
Archer and Phoenix Perp additionally present a reasonable enhance that in precept shouldn’t be appropriate with an intense market making exercise.
Nevertheless, by inspecting transactions, we clearly see a number of updates aggregated collectively (see eg. exhibit A and exhibit B). It’s because updates can get entry to the 1.4M CU with the identical base payment. Thus right here it’s necessary to evaluate the affect on operations as soon as MMs orders are decoupled.
At this charge, MM actions will see non-negligible impacts on every day operations.
Aggregators
Aggregators are one of many core part of buying and selling exercise on Solana.
Fig. 9: Distribution of payment enhance for Aggregators. Supply:
Dune.
These are the one principally affected by this proposal. With present price unit utilization:
- Jupiter will see a median enhance of 0.000068 SOL, p10 at 0.000025 SOL and p90 at 0.00010 SOL
- Titan will see a median enhance of 0.00010 SOL, p10 at 0.000046 and p90 at 0.00015 SOL
- DFlow will see a median enhance of 0.00012 SOL, p10 at 0.000053 and p90 at 0.00018 SOL.
It’s clear that extra heavy on-chain routing require extra in payment.
Poisonous Stream
SGP-0003 has an oblique impact on poisonous move.
Right now, a major quantity of liquidity concerned into on-chain arbitrage flows between propAMM venues. These trades income from very tiny costs variations. Certainly, revenue extracted is ridiculously low with respect to the liquidity used. Supply: Dune.
SGP-0003 will enhance the associated fee to extract this worth, forcing arbitrage bots to behave provided that the alpha is excessive sufficient.
Affect on Validators
Right here the affect is twofold.
On one facet, validators can pay much less in vote payment (with a 12.3% discount). Certainly, assuming 3765 requested price, underneath SGP0003 validators can pay
This represents a discount on each vote price, after which rewards accrued by validators.
On the opposite facet we now have discount resulting from lower of flat payment to 2500 lamports.
Fig. 10: Change in SOL rewards per block distribution. Supply:
Dune.
Certainly, underneath SGP-0003, protocol payment income is unchanged for single-signer transactions however decreases for multi-signer transactions. This produces the distribution of losses per block displayed in Fig. 10. Given the present snapshot, the anticipated worth of SOL lower per block is 0.00015 SOL.
Affect on SOL Provide
The principle objective of this SGP is to extend the burn charge.
To estimate the attainable burn charge we assume 3 completely different case:
- Present Value Unit consumed with no extra in requested assets
- Present Value Unit consumed with an extra in requested assets akin to the p75 of extra of txs specifying each CU and loaded knowledge dimension restrict
- A ten% common discount (resulting from optimization) of present Value Unit consumed.
Fig. 11: SOL burn charge underneath SGP-0003. Orange line represents the optimized setup, the place on
common all assets are decreased by 10%. Grey line represents the present price models utilization with
an extra in requested assets equal to the p75 of extra confirmed by txs specifying each CU and
loaded knowledge dimension. Pink line signify the present Value Unit consumption with no extra. Blue line
is the present burn charge. Supply: Dune.
Below these assumption, SOL burn strikes from
- Between 30k and 35k SOL per epoch within the worst optimized setup
- Between 8k and 10k SOL per epoch within the no-excess case
- Between 6k and 8k SOL per epoch within the optimized case with no-excess in requested assets.
Clearly, these numbers are speculative as a result of we don’t know the way builders will react and what the longer term useful resource utilization will probably be.
