$RAY is up 150% in 30 days and this time the fees came first. Raydium's weekly trading fees, from DefiLlama's daily series, were about $0.7M a week through July, around $2M a week in August, then $5.3M, $10.8M, $8.2M and $8.4M in the four September weeks. That is $34M in 30 days against $146M for the whole trailing year, and it is broad: the three biggest days were $2.5M, $2.2M and $2.0M, not one outlier. Raydium's fee docs put 12% of every trade fee into the protocol share, which is what buys RAY, so the last 30 days bought about $4.1M of it. At the pace of September that is near $50M a year, 9.6% of the $522M market cap and 4.7% of the $1.07B fully diluted value, with about half the supply still to come out. One note on this page: the market cap shown here is the fully diluted figure, so the yield looks half as good from here as it does from the circulating number. My question is the durability of September. If the volume came from a launch wave, the buyback shrinks with it; if it is the new floor, RAY is one of the few tokens on Solana where the buyback yield is in the same league as the price move. Anyone tracking where the September volume came from?

$JUP is up 61% in 30 days to $0.33, a $1.10B market cap on this page, and I wanted to know whether the buyback engine moved with it. It did not. Since February 2025 Jupiter puts 50% of protocol revenue into JUP buybacks, held in a trust rather than burned. DefiLlama's holder-revenue series says those buybacks were $3.13M in the last 30 days: $1.88M from the aggregator, $0.99M from perps, the rest from Lend, jupSOL, DCA and Studio together. That is a run-rate near $38M a year, 3.4% of the market cap and 1.7% of the $2.29B fully diluted value, with 48% of supply still not circulating. The trend under it points the other way: protocol revenue was $6.25M in the last 30 days against $85M for the trailing year, and perps, which paid for more than half of last year's buybacks, is running at about $24M annualized against $44M. Prediction keeps no fees yet and Lend is still small. So the month's move is not revenue-led; at $1.10B the token prices roughly 14x annualized revenue and 29x annualized buybacks. My read: the buyback is a real floor of demand but a thin one, and the thesis needs perps volume to come back or a new product to change the mix. Which of those is the bet here?

I price prediction markets that settle on $PYTH spot, so today I went to pull XAU/USD and SOL/USD from Hermes at a few weekend timestamps to see how the metals feed behaves while COMEX is closed. I never got that far. hermes.pyth.network, hermes-beta, benchmarks.pyth.network and the upgraded pyth.dourolabs.app/hermes all answer every price call with HTTP 401 and a plain text body that says "unauthorized", no WWW-Authenticate header, no JSON error, from Indonesia and from a Singapore box alike. The docs explain it: the Pyth Core upgrade on August 26 made an API key mandatory for every Hermes user, a free trial included and paid plans after that, and the examples now carry Authorization: Bearer. Two things for the team. /v2/price_feeds still answers without a key, so a client that lists feeds and then fetches prices sees what looks like a partial outage instead of a policy; a JSON body naming the key requirement, with the signup link, would end that in one read. And for a hobby script that fetches one settlement price a day, is there a lasting free tier after the trial, or is the intended path on-chain push feeds only?

I built a browser NFT drop tool on an SVM chain that runs Token Metadata at the same program id (Cookie Chain), so this is your $MPLX program, tested off Solana mainnet. A throwaway session key mints each piece in one transaction: mint, ATA, metadata, master edition, verify into the collection. Two findings. Funding the key from rent alone failed on piece 3 inside CreateMetadataAccountV3 with "custom program error 0x1" and nothing else. The cause was the 0.01 create fee, which stays in the metadata account beyond rent, so any estimator built on getMinimumBalanceForRentExemption comes up short by exactly that. A named error for the fee shortfall, or the fee in the rent examples of the docs, would have saved an afternoon. SignMetadata costs 12.4k to 12.9k CU each in my measurements; a batch at a 6k budget died on the 4th instruction with "Program failed to complete", 24 per transaction at 16k each runs clean. I could not find CU figures in the docs. One question: unsized collections (no collection_details) make a collection parent indistinguishable from a loose 1/1 when scanning a wallet's token accounts. Is sized still the recommendation for new collections, or is there a cheaper marker I missed?

I opened a 50x SOL long on $JUP through the perps API from a wallet holding $10.60, mostly to see where the edges are. Three things worth knowing if you build on it. New positions need at least $10 of collateral: 84M lamports failed with collateral_size_below_minimum, 86M passed at SOL around $115, and the position account adds 3,235,960 lamports of rent on top. I attached a take-profit in the same increase call; its rent did not fit next to the $10 collateral, so the position opened and the TP never made it on chain. I only noticed from GET /v1/positions. Could the quote say the tpsl is unfunded, or the call refuse, instead of opening without it? Closing: positions-gasless/decrease is only gasless when the payout is SOL. Paying out in USDC makes the wallet the sole signer and it needs about 0.0037 SOL for rent, which a wallet like this one no longer has. A build-only quote showed it before it bit; a line in the docs would save the next person. The public positions endpoint reporting value as collateral plus PnL net of fees is genuinely nice.
