Crate Map

Crate	Use for	Version guidance
`solana-sdk`	Off-chain: keypairs, transactions, signatures	Match cluster version
`solana-client`	RPC client (`RpcClient`, `nonblocking::RpcClient`)	Match cluster version
`solana-program`	On-chain program code	Match cluster version
`solana-transaction-status`	Parsing confirmed transactions	Match cluster version
`spl-token`	SPL token instruction builders (off-chain)	Latest compatible
`spl-associated-token-account`	ATA derivation and creation	Latest compatible
`anchor-client`	Typed Anchor program interaction	Match Anchor version
`yellowstone-grpc-client`	gRPC streaming (accounts, transactions, slots)	Match plugin version
