Introducing Playnet!. Playnet is a minimal runtime that can execute Solana programs on ANY platform. The code is open source: and will be used in Solana Playground to create even better dev experience.

Released VSCode extension for Solana Playground!. Supports building and deploying programs(Native, Anchor, Seahorse), sharing code, wallet support and program snippets. And all this without relying on any other program, shouldn't have any issues on Windows!

Anchor v0.31.0 is finally out!. It's likely going to be the last major release before v1. Highly recommend checking out the release notes before upgrading.

Priority fees are now supported for program deployments on Solana Playground!. (It already had infinite retry for buffer writes.).

Fixed almost all issues with the Anchor IDL!. - New IDL spec.- Rewrite IDL generation.- TypeScript improvements (account-resolution, no case conversion. ). If you depend on Anchor in any kind of way, consider giving feedback.

Solana is getting faster. Anchor is getting faster. and today, program deployments are ~3x faster(even without Anchor 0.29.0) in Solana Playground!.

Anchor programs just got a lot more efficient. Instead of cloning each account passed to the program, we're now using references @exoaursen. This, along with some other changes results in program binaries that are 33% smaller compared to the last release.

Anchor v0.30.1 is out!. Includes various improvements and bug fixes. Most notably, the conversion of legacy IDLs to the new IDL spec.

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

Adding a new account type that optimizes memory and compute unit usage. If you're running into stack memory problems, try it out to see if it fixes those problems.

How many people got scared when they first saw the code above to transfer lamports from a PDA?. Added methods to make lamports operations easier in Anchor Abstractions usually sacrifice performance but in this case, the code below uses less resources.

Added a command in @anchorlang to keep program ids in sync between the program files, `Anchor.toml` and the actual program public key. New programs will be created with the correct program id by default.(No more build, replace, rebuild cycle).

This simple check can catch all overflows in your codebase without having to use checked methods. The best part is, it will also catch unexpected overflows in your dependencies. Next Anchor version will require this check to be specified:

Multiple wallets and Wallet Standard support comes to Solana Playground today. This allows running code using any wallet in a type safe manner.

This token is NOT affiliated with the real project in any way. Solana Playground was created as an open-source public good. Even though my recent grant proposal to the Solana Foundation was rejected, the project still has support from @_cubik.
ok i called some larp, made money with my bois and as soon as i found out its larp, . pinged on my telegram to sell,. i made 50 sol, profit which is 5x for me, its still running. but for gods sake, its fucking larp. @solplaylive. product launched 2 years ago, token launched.

Pretty wild that `Box`ing the error variants in Anchor reduced the program binary size by ~7%.

@L0STE_ Correct. This is because `LazyAccount` impl requires discriminators but spl-token accounts don't have them.

For @anchorlang and @seahorse_lang you have access to the program out of the box. Instead of doing a bunch of boilerplate setup, this could be the first line of your code:

@aeyakovenko @solana @anchorlang @armaniferrante Most of the IDLs are already in this repo. Could require some manual changing because it's not perfect but it's 95% done IDL wise.

@redacted_noah @therealchaseeb @Eliascm17 @soundsonacid @solanaturbine @deanmlittle Exactly. Especially once we get rid of the lifetimes from Anchor, pretty much any programmer should be able to pick up Anchor within a day. The hard point has always been understanding the accounts part, which can be abstracted.

@therealchaseeb @solana Unnecessary level of complexity is setting a higher barrier of entry. Low level stuff needs to be abstracted away, Anchor is a great example of this. We need more tools like Anchor.

@jacobvcreech @cryptopapi997 Allowing both v1 and v2 at the same time means every downstream project that depends on the old functionality, e.g. `anchor-spl`, would also need to allow the same version requirements as SPL. If this solution forces us to make a new release, what was the point of v2 anyway?.

I spent over 24h trying to upgrade a smart contract on @solana yesterday. If it wasn't for @acheroncrypto and Sol Playground, the upgrade would have to wait. This tool literally will not allow any transactions to fail, basically guaranteeing deployments.

@_nighthawk69_ @jacobdotsol @ngundotra @callum_codes Yeah it's currently expecting a project to build, you can just create an empty Anchor project and build it once and the problem should go away. Should definitely make this easier for external programs though. Also the above screenshot is from 2022, it looks like this now

Since tutorials are made with React components, you are not limited to making tutorials with Markdown. Not only you can create and display your own components but you also have access to all of the playground codebase!.

@realbuffalojoe @armaniferrante Not sure if it's valid but a GitHub action to automatically close PRs that change the `borsh` version in Solana repo would greatly reduce the dependency issues.

@therealchaseeb @mmatdev @gumdalf_ @sssionggg > Can Solana playground upload to a buffer account?. It does upload to a buffer account but not to an existing one (creates a new one). It wouldn't be too hard to support writing to an existing buffer account though, if that's what you want.

@callum_codes `toolchain` will definitely help because a lot of problems are caused by having an incompatible Solana version and you don't have to manually switch versions now.

@kunal_chhabra37 Yes, we can definitely have that option. Currently you can export the project as .zip but without Cargo.toml.

@jacobvcreech @redacted_noah @burger606 None of these breaking changes are coming from Anchor though. It's all resulting from:. - Crates not following Semantic Versioning.- Libraries being a lot more specific than they need to be in their manifest files.- Bumping borsh version.

@jacobvcreech @0xk2_ @splitoor @bill_papas_12 @0xNazreen Yeah, CPI and some syscalls don't work properly due to the implicit 64bit assumption SVM has. I think it should be much easier to create something like Playnet today than it was 2 years ago (had so many dep issues back then). Client-side interaction is also implemented.

@redacted_noah Compilation of dependencies should only happen once, subsequent runs are cached. To make CI faster, one could cache the dependencies using `anchor build` uses `cargo-build-bpf` under the hood so optimizations would not be Anchor specific.

@armaniferrante @nicovrg_ It's possible to hide most (maybe all) of these lifetimes from the user by using `transmute`. Shortening lifetimes should be fine (other cases are UB afaik), but adding a bunch of unsafe code doesn't seem nice.

@vidor_solrise @solflare_wallet There is no Backpack or Phantom specific code for this, all standard wallets should be able to connect.

@ananas_light Zero copy is much more efficient compared to this, but it also has very strict requirements that make it difficult to use. `LazyAccount` is much more flexible (supports complex types) and is more of a replacement for regular accounts rather than zero copy accounts.

@therealchaseeb @JupiterExchange @KyleSamani @jacobvcreech @SolanaCookbook Unfortunately, most programs are not open source including @JupiterExchange but they share program instructions for integrations.

@AndreaChello @jacobvcreech @0xk2_ @splitoor @bill_papas_12 @0xNazreen It's being used, but it's currently hidden in production builds because it's mostly useless without CPI (can't even use the Anchor `init` constraint). You can play with it from the website if you run `solana config set -u http://playnet`.

@redacted_noah @therealchaseeb @Eliascm17 @soundsonacid @solanaturbine @deanmlittle A lot can be improved, but it's quite difficult to make big changes to Anchor. It's possible to completely abstract accounts from app developers. Whether we should do it or not is another question, but I'm a bit surprised that nobody has done it yet.
