[experimental] Add functions for adding priority fees to transactions

[experimental] Add `minContextSlot` to the lifetimeConstraint for nonces

## Motivation It's important to know _what_ slot a nonce should be considered valid for when confirming a transaction. If you get nonce at slot X but then when you...

[experimental] Discussion: Extending an RPC with custom methods

5

## Motivation We've written a comprehensive typespec for the Solana JSON-RPC in `rpc-core`. If you're using an RPC that offers _more_ than the methods we've specified, you might like to...

## Motivation You're an application that depends on a bunch of packages (`mpl-token-metadata`, `@solana/wallet-adapter-react`, etc.) and those packages themselves depend on `@solana/web3.js` (the legacy version). Each of those packages use...

[experimental] program derived address assertion and type guard functions don't actually assert that the address is off the curve

`assertIsProgramDerivedAddress` and `isProgramDerivedAddress` don't actually check to see if the address is off the curve. All they do is validate the _format_ of the tuple. Someone _could_ supply a regular...

[experimental] Figure out how to write an assertion function for fully signed transactions while TypeScript does not support async assertions and typeguards

3

See https://github.com/microsoft/TypeScript/issues/37681#issuecomment-1650605236. Essentially you can write an assertion function ([playground](https://www.typescriptlang.org/play?#code/C4TwDgpgBAcgrgWwEYQE4BkIGcsBUAWAhgHa4TFQC8UxiKqUAZFAN5SoSEAmA9sQDYgoSVCS4AuKHGIBLAI5xoWEMh78oAXwDcUALAAoAwDNpAY2Ay+UQjjTAAklkw4CJAIwAGABS0Ek3-QAlJI2WHZYNIhQMhHwyGjOeESk5KwGUNFGUD5RAHzUnoFp+hkZwPioPADuNBA1AKKolaheAOS4PDzCMgDmrYFa6ZoGGgamfFjAkQhUUACcg-qhdo6JrsSeOQgDBr5QWIQWWEYy2LB0CdhJJGTEWkA))… ```ts type NumberLessThanTen = number & { readonly brand: unique symbol }; function assertIsLessThan10(num: number): asserts num is NumberLessThanTen {...

Add documentation for everything exported from `src/transaction.ts`.

[experimental] Should `responseProcessor` be async?

2

At the moment, an RPC API's requests can include a `responseProcessor` that transforms the server response before it reaches the caller in the client. We use this, for instance, to...
