v0.1.7 — Native programs and confidential transfers

Highlights

• Added native codecs for the Compute Budget, Loader v2/v3/v4, Address Lookup Table, Stake, and Vote programs.
• Added SPL Token, Token-2022, and Metaplex Token Metadata instruction and account codecs.
• Added the complete Token-2022 confidential-transfer suite in the isolated programs/token-2022 module: current and legacy key derivation, AE and ElGamal encryption, all 12 ZK proof discriminators, transfer fees, confidential mint/burn, proof context and record accounts, the ElGamal registry, and composed transaction workflows.
• Added native proof verification, stable error classification, boundary and concurrent race coverage, and interoperability tests against the Solana Rust verifier from solana-foundation/solana-go PR #484.
• Native confidential proof generation and verification is 9.1–11.5x faster than the compared WASM implementation on the documented benchmark machine.
• Added a runnable confidential-transfer example that builds a signed SIMD-0385 v1 transaction, validates its 4096-byte envelope, and base64-encodes it for RPC submission.

Install

go get github.com/fluxrpc/solana-go@v0.1.7
go get github.com/fluxrpc/solana-go/programs/token-2022@v0.1.0

Token-2022 remains a separate Go module, so projects that do not use confidential transfers do not inherit its cryptographic dependency graph.

What's Changed

• Native program codecs in #10
• SPL Token and Metaplex codecs in #11
• Token-2022 confidential-transfer suite in #12

v0.1.2 — Message account helpers

Message account helpers

Gagliardetto-compatible helpers on the static account keys, added for downstream migration (first consumer: alphabatem/rpc_shard):

• Message.Account(index uint16) (PublicKey, error)
• Message.AccountMetaList() (AccountMetaSlice, error) — returns the new ErrAddressTablesNotSet sentinel for versioned messages that reference address table lookups (this package carries no lookup-table resolution)
• Message.IsWritableStatic(PublicKey) bool — implements the message account-ordering rule with saturating arithmetic, same as upstream Rust
• Message.UnmarshalBase64(string) error
• PublicKeySlice.ToBase58() []string

Base58 interning on the String paths

PublicKey.String and Hash.String now serve repeated keys from base58.EncodeCached32's lock-free intern table — these APIs allocate a string regardless, so a cache hit erases the allocation entirely (program IDs, mints, hot accounts and blockhashes repeat constantly in Solana workloads). The hand-built JSON writers are unchanged and keep encoding directly into the output buffer; JSON output is byte-identical.

v0.1.1

What's Changed

• feat: TransactionFromBytesConsumed for concatenated buffers by @cloakd in #2

Full Changelog: v0.1.0...v0.1.1

v0.1.0 — binary decoder

New: solana-go/binary

A minimal, reflection-free decoder for the little-endian ("bincode") and Borsh layouts used by Solana account state and instruction data. No encode side, no struct tags — callers read fields explicitly in layout order, so every read is a bounds check and a fixed-width load.

• Sticky-error Decoder: read a struct with straight-line calls and check Err() once at the end. Cold paths record bare sentinels; offset context is formatted lazily, keeping the hot reads inlineable and allocation-free.
• Reads: Uint8/16/32/64, Int64, Bool, Bytes(n) (zero-copy, with Copy variant), BorshString (zero-copy via unsafe.String, with Copy variant), typed PublicKey / Signature / Hash, Borsh Option and SPL COption tags (validated), canonical compact-u16 (shortvec) lengths, Skip / Pos / Len / Remaining.
• Sentinel errors matchable with errors.Is: ErrUnexpectedEOF, ErrInvalidTag, ErrNonCanonical, ErrOverflow.

Benchmarks vs gagliardetto/binary

Operation	fluxrpc	upstream	speedup
SPL token account decode (165 B)	36 ns, 0 allocs	150 ns, 1 alloc	4.1x
Metaplex metadata (zero-copy strings)	123 ns, 1 alloc	369 ns, 5 allocs	3.0x
Metaplex metadata (copied strings)	202 ns	336 ns	1.7x
compact-u16 (3-byte worst case)	6.5 ns	8.6 ns	1.3x

Verified by differential parity tests in benchcmp (identical decode results vs upstream on token account, mint and metadata fixtures, plus the full 0–0xFFFF compact-u16 range) and 700k+ fuzz executions with no panics.

Root package additions

• MPK(string) PublicKey — convenience alias for MustPublicKeyFromBase58.
• PublicKeySlice — []PublicKey, JSON-encodes as an array of base58 strings.
• TransactionFromBase58 — base58 counterpart to TransactionFromBase64.
