Crate outscript 

outscript generates potential output scripts for a given public key.

It supports Bitcoin and Bitcoin-like cryptocurrency output script formats (P2PKH, P2SH, P2WPKH, P2WSH, P2PK, P2TR, etc.), EVM-based networks (Ethereum and compatible chains), and other blockchains such as Litecoin, Dogecoin, Namecoin, Monacoin, Electraproto, Dash, Bitcoin Cash, Massa and Solana.

This is a Rust port of the Go library github.com/KarpelesLab/outscript. All cryptography is provided by the purecrypto crate.

Modules

address

Address parsing and encoding across Bitcoin-family, EVM, Massa and Solana networks (port of address.go, eip55.go).

base58

Base58 encoding using the Bitcoin alphabet.

bech32

Bech32 / Bech32m segwit addresses (BIP-173 / BIP-350) and Bitcoin Cash CashAddr encoding.

btcguess

Heuristics to recover a public-key hash (and possibly the pubkey) from a Bitcoin output or input script (port of btcguess.go).

btctx

Bitcoin transactions: building, signing (legacy, segwit BIP-143, taproot BIP-341/340), serialization and parsing. Port of btctx.go and btctx_p2tr.go.

btctxparse

Parsing/extraction of signatures from Bitcoin input scripts and recomputing the sighash they committed to. Port of btctxparse.go.

crypto

Cryptographic primitives used by outscript, built on purecrypto.

evmabi

EVM ABI encoding (port of evmabi.go).

evmtx

EVM transactions: legacy, EIP-2930, EIP-1559, EIP-4844. Build, sign, serialize, parse and recover sender. Port of evmtx.go.

hash

Hashing helpers built on purecrypto::hash.

insertable

Composable Insertable operations that define how an output script is derived from a public key (port of the Go Insertable/Format types).

massa

Massa address parsing (port of massa.go).

out

The Out type: a generated output script with format name and network flags, plus script-recognition helpers (guess_out, get_outs).

pubkey

Public-key abstraction used by crate::script::Script.

pushbytes

Bitcoin script PUSHDATA encoding/decoding.

reward

Block reward and cumulative-supply calculations across networks. Port of reward.go.

rlp

RLP (Recursive Length Prefix) encoding/decoding.

script

The Script engine: holds a public key and generates output scripts for various named formats, caching results.

solana

Solana keys, instructions, transactions (legacy + v0), program-derived addresses. Port of solanatx.go, solana_instructions.go, solana_pda.go.

solana_addr

Solana address parsing (port of solana.go).

Structs

BtcAmount

A Bitcoin amount in satoshis (1 BTC = 100,000,000 satoshis).

BtcVarInt

A Bitcoin variable-length integer as defined in the Bitcoin protocol. Values 0-0xfc are a single byte; larger values use a prefix byte (0xfd, 0xfe, 0xff) followed by 2, 4, or 8 little-endian bytes.
