Today I started my new job for solana foundation as a dev rel! \o/ First stop turkey. Birlikte @solana inşa ederiz!

I am still mind blown that it is really possible to build a realtime multiplayer game on @solana. If someone asks you if solana is fast, just show them this. :D

.@Solana has a HUGE problem! Compressed NFTs are way too cheap. 0.000005 sol per mint is crazy. So we came up with a solution. Let's just mint every pixel of an NFT as an NFT to balance things out. Introducing the

Just deployed my first solana program on the @solana saga phone using playground. Just normal solana things 🤷♂️
Big update for Solana Playground today!. - Share any file(s) you'd like.- Import any GitHub program repository(including tests) - Import a local program workspace with drag & drop.- Export with framework layout, e.g. with default Anchor project files

Mhmmm the @solana Unity SDK looks really in the verified Unity asset store 😍 I think its the best Solution to build blockchain games. Check it out here: and here are some example games build with the sdk:

Omg!! I added socket subscription to the game data account. Look at this @solana speed!! Every move is a transaction on a decentralized blockchain. 🤯🤯🤯

21 million dollar depin idea: build a tiny lorawan distance sensor and glue it in all parking spots in a city and make an app that shows where free parking spots are. Then let people rent out the parking spots in front of their garages via solana pay qr code signs and in the app.

DevEx became a little easier today. With web3.js version ^1.92.1 you will now always see the transaction logs with the proper error instead of 0x0 or 0x1. Especially helpful during anchor tests. :) And when preflightChecks are disabled you can now call getLogs() on the error to

Yay I greatly improved performance today by adding a byte to instruction to be able to have duplicates in the same block and loading the block hash ahead of time. \o/ But this is not @solana max speed yet. @jordaaash gave some more tips to make it even faster 🚀-also wen 🔥💃🏼?

Due to popular demand, I made a video on how to write solana programs in C and disassemble both C and Rust code. Check it out! :)

I fixed many live bugs in my life and it was always stressful. In traditional games we always had full control of the code and servers. Seeing live how @Solana coordinated thousands of network participants within just a few hours to all pull on the same string is truly amazing.🤯.

I got the question a few times which onchain games would be possible on @solana. Its easy, ANY game is possible that comes out with a 500ms ping.Think rts/roundbased/idlegames/towerdefence/poker/tradingcards/quiz/sandbox/citybuilder/etc and they will soon be playable as xnft/dApp.

Another day another @solana on chain game dev stream. Today we added Chtuluh shooting at the closest pirate ship. (Every game action is a transaction) Follow on twitch to not miss the next one.

After @solana plays pokemon the next goat will be the person hosting the first on chain speed chess match between @aeyakovenko and @VitalikButerin. 🧵 Thread with tips on how it could be built 1/n👇 #SolanaSandstorm ?

Here is my proposed IDL solution for native @solana programs using a metadata program instead an empty anchor program. Supports compressed json or url. Would love to get some feedback on it. 🤗

I think dynamic onchain metadata on nfts is really cool! Especially for games \o/

Proud to announce 28 new game programs have been deployed to dev net today! 🤯 Thanks to the super engaged audience, I had a blast :).
🪚 Want to build a game?. @SolPlay_jonas from @SolanaFndn is in the house to talk about building an on-chain game on @solana. #HackerHouseIstanbul

Yay it builds \o/ I made a github action that can build any solana program, verify and upload idl. Also works locally using act. Still needs some work, but coming to a helper package in your area hopefully soon 🚀

Im sorry, but many people asked for it, so I made a video on how to write a @solana program in Assembly. Big thanks to @deanmlittle for building sbpf tools! Video👇

This is how you can get a @solana auto approve wallet on mobile. Create a second wallet in the game. Then do a deeplink transaction from a wallet on the phone to your in game wallet. Use in game wallet for game transactions. Voila!

Today I learned there is an open-clockwork fork maintained by the goat @tuanpmhd from @SuperteamVN. It compiles with anchor 28 and the validator plugin is also compatible with 1.16. Who is going to run it on devnet? 😍

Did you know there is a “rust_analyser” vscode extension? Finally i have proper code completion again \o/ If you are a @solana dev and like code completion i can recommend!

You know what would be cool for composability? A list of all frozen @solana Programms with their idl and a short description what they do. Do you think it would be possible to build that? 🥰.

First game released built with Unity SDK as xNFT in @xNFT_Backpack already. It's as easy as pick the xNFT WebGL template from within unity 🤯 Try it:
Zen Republic App goes xNFT! If you're on @xNFT_Backpack already, go here to mint our app: Having downloaded the app, you will be able to launch it right from your wallet 🎒🪐. The future is now, no dull moment!

I think the first dApp with 30k downloads in @solanamobile dApp store will be Solaroid! An app which lets you mint fotos into NFTs and directly send them to your friends via @saydialect. Just who will build it?

Did you know you can make your workflow on @solana Playground even faster by running a local validator? Just type "solana-test-validator" in your terminal and pick local host in Playground. Deploy and test in 5 seconds + get 100 sol for free \o/

Many devs in the last weeks asked me how to make accounts bigger than 10Kb with anchor in @solana , what heap and stack limits exist and what zero copy is. I made an example repository: And will soon make a video explaining it and writing some docs.

What is your favorite @solana function? Mine is for sure "onAccountChange" to get realtime updates on any account! The Solana UnitySDK also supports this function btw using streamingRPCs.

Imagine you have a @solana on chain game and then stream every build/kill/win/pickup/purchase or ranking change live to your discord server. Setup in under 30 seconds. 🤯.
NEW: DISCORD WEBHOOKS ON SOLANA. You can now connect Helius webhooks to a Discord channel in under 30 seconds. Simply select the transaction types to listen to, input accounts to watch, and input your Discord webhook URL. That's it. Have fun!

Finished the @solanapay Tug of war game. Can be played on a big screen on conferences for example. Scanning the codes will open a transaction on the players phones that controls the game. It's open source. Can't wait for cool party games to be build! \o/ .

So after todays stream we have a @clockwork_xyz thread moving ships every two seconds on chain now. Sadly it's not really fun to have them move automatically I figured. But cool never the less. :D This is how it's done:

We all know by now that @solana play ground is awesome, but did you know you can grind your own cool program address and upload the keypair for your program? This is the one for Tiny Adventure: tinyiK8HcU7WuLW6tfss8PJqpcVzS5Ce9M9ATXEhJGr

Just tried @heliuslabs RPC and must say its really fast! Works with websockets and 100k requests are free. The webhooks are super. \o/ Is there also a helius devnet rpc available? 🤔 That would be nice. Solana is lagging free reliable devnet RPCs imo.

.@Solana is cheaper than aws. 🤷♂️.
@Rockooor One of the main reasons we are developing @sol_dungeon as an on-chain game is that we can use Solana as our cloud server solution. It's cheaper than AWS.

Compressed NFTs use merkle trees so save a proof on chain that can quickly validate that the NFT data cached off chain by the RpcNodes is correct.If you are intimidated by merkle trees its maybe good to know that GIT also uses merkle trees and thats why the root it called root.🌳.

Such a beautiful award winning phone. 😍😍 Tutorial on how to submit to the dapp store coming in the next days. 🥸.
Bust of the Year: Solana Saga Crypto Phone. No amount of #BONK or Cryptosaurs could save this phone. It’s a shame this ceramic build was wasted on a weak camera, display and battery. You can find defenses of this phone, but you’re not already a $SOL holder, they’re meaningless

Cool video about the history of the saga phone. Someone pls take the solana mobile stack and expand it to other blockchains. Its all open source. Maybe we can make it so its relevant for 0.1% of all people. Then 2% and so on 🚀.

Did you know your Anchor PDA can be owned by another program? As long as the PDA is derived from your ProgramId the program will always be able to sign for it no matter the owner: #[account(.init,.seeds = [b"systemPda"],.bump,.space = 0,.owner = system_program::ID)].

The difference between eth and sol validators is that on eth they are run to maximize profit and extract value. On solana eventually all will be run by projects that need the performance and swqos to provide best performance for their users. You can see it already with @helius or.
