What it does. 1) SDK: @solana/kit (v7+) first - Build clients with

createClient()

from

@solana/kit

, then

.use(...)

plugins:

Default to
```
signer()
```
/
```
signerFromFile()
```
/
```
generatedSigner()
```
from
```
@solana/kit-plugin-signer
```
— they set both
```
payer
```
and
```
identity
```
to the same keypair (the common case). For fresh local/devnet signers, install the RPC/LiteSVM plugin after
```
generatedSigner()
```
, then fund with
```
airdropSigner(...)
```
. Reach for the role-specific variants (
```
payer()
```
+
```
identity()
```
) only when fees and authority must come from different keypairs. - Use
```
@solana-program/*
```
program plugins (e.g.,
```
tokenProgram()
```
) for fluent instruction APIs. - Prefer Kit types (
```
Address
```
,
```
Signer
```
, transaction message APIs, codecs). - Transaction v1 (4096-byte transactions, SIMD-0385) is the one exception to the plugin-client default:
```
rpcTransactionPlanner
```
throws on
```
version: 1
```
today, so v1 needs
```
@solana/kit
```
8 and the manual
```
pipe()
```
path. See transactions-v1.md.

Highlights

Solana dApp UI work (React / Next.js)
Wallet connection + signing flows
Transaction building / sending / confirmation UX
Transaction v1 / larger transactions (SIMD-0385) — sending, reading, indexing
On-chain program development (Anchor or Pinocchio)

When to use it. Use when user asks to "build a Solana dapp", "write an Anchor program", "create a token", "debug Solana errors", "set up wallet connection", "test my Solana program", "fuzz my Solana program"…
