Bitcoin Improvement Proposals index, organized by topic. Active soft forks, wallet standards, network protocol, format standards. Pointers to canonical text and historical context. USE WHEN: looking up a BIP number, citing a standard, or understanding the relationship between related BIPs.
What this skill does
# BIP Index (topic-organized) Canonical: `https://github.com/bitcoin/bips`. Each BIP's status: **Draft** → **Proposed** → **Final** / **Active** / **Replaced** / **Withdrawn**. ## Process - **BIP 1, 2** — BIP process itself. ## HD wallets and key derivation - **BIP 32** — Hierarchical Deterministic Wallets. - **BIP 39** — Mnemonic seed phrase. - **BIP 43** — Purpose field convention. - **BIP 44** — Multi-account hierarchy (legacy P2PKH). - **BIP 49** — Derivation for P2SH-P2WPKH (`m/49'/0'/0'`). - **BIP 84** — Derivation for native P2WPKH (`m/84'/0'/0'`). - **BIP 86** — Derivation for P2TR (`m/86'/0'/0'`). - **BIP 85** — Deterministic entropy from BIP32 (sub-seeds). ## Output and address formats - **BIP 13** — P2SH addresses (`3...`). - **BIP 16** — P2SH consensus rule. - **BIP 141, 143, 144, 145, 147** — SegWit family. - **BIP 173** — Bech32 (segwit v0). - **BIP 350** — Bech32m (segwit v1+). - **BIP 380–385** — Output descriptor language. - **BIP 389** — Multipath descriptors. ## Taproot - **BIP 340** — Schnorr signatures. - **BIP 341** — Taproot output / key-path / script-path / merkle. - **BIP 342** — Tapscript validation rules. ## PSBT - **BIP 174** — PSBT v0. - **BIP 370** — PSBT v2. - **BIP 371** — Taproot fields in PSBT. ## Time locks and sequence - **BIP 65** — `OP_CHECKLOCKTIMEVERIFY`. - **BIP 68** — Relative locktime via nSequence. - **BIP 112** — `OP_CHECKSEQUENCEVERIFY`. - **BIP 113** — MTP for nLockTime. ## Mempool / replacement - **BIP 125** — opt-in RBF. - **BIP 152** — Compact block relay. - **BIP 156** — Dandelion++. - **BIP 157** — Compact block filter client. - **BIP 158** — Compact block filter format. - **BIP 331** — Package relay. - **BIP 339** — wtxid relay. - **BIP 431** — TRUC (v3) transactions. ## Network / P2P - **BIP 31** — pong message. - **BIP 35** — mempool message. - **BIP 37** — Connection bloom filtering (deprecated). - **BIP 130** — sendheaders. - **BIP 155** — addrv2 (Tor v3, I2P, CJDNS). - **BIP 324** — Version-2 P2P transport encryption. - **BIP 330** — Erlay (proposed). ## Soft fork activation - **BIP 8** — versionbits with lockinontimeout. - **BIP 9** — versionbits. - **BIP 34** — Block v2 (height in coinbase). - **BIP 90** — Buried activation heights. ## Wallet UX standards - **BIP 21** — URI scheme `bitcoin:address?amount=...&label=...`. - **BIP 47** — Reusable Payment Codes (PayNyms). - **BIP 78** — PayJoin. - **BIP 137** — Generic message signing. - **BIP 322** — Generic signed message format (modern). - **BIP 329** — Wallet labels portability. - **BIP 352** — Silent Payments. ## Multi-party signatures - **BIP 327** — MuSig2 (Schnorr key aggregation). ## Hardware wallets - **BIP 174 / 370 / 371** — PSBT (also covers HW signing). - **BIP 388** — Wallet policies for HWs (Ledger, etc.). ## Proposals (not active on mainnet) - **BIP 119** — `OP_CHECKTEMPLATEVERIFY` (CTV). - **BIP 118** — `SIGHASH_ANYPREVOUT` / `ANYPREVOUTANYSCRIPT`. - **BIP 300/301** — Hashrate Escrows / Drivechains. - **BIP 345** — `OP_VAULT`, `OP_VAULT_RECOVER`. ## Reading order for newcomers 1. BIP 32 → 39 → 84 → 174 (foundations of any wallet). 2. BIP 141/143/144 (SegWit). 3. BIP 340/341/342 (Taproot). 4. BIP 380–385 (descriptors). 5. BIP 327 (MuSig2) and BIP 322 (message signing). ## Lookups - Repo: `github.com/bitcoin/bips`. - Master index file: `README.mediawiki` lists all BIPs with status. - Some BIPs are withdrawn or replaced; check status before citing. ## See also - [consensus/SKILL.md](../consensus/SKILL.md) - [proposals/SKILL.md](../proposals/SKILL.md) - [psbt/SKILL.md](../psbt/SKILL.md) - [descriptors/SKILL.md](../descriptors/SKILL.md)

gate-dex-trade
IncludedExecutes on-chain token swaps via Gate DEX. Use when user wants to swap, buy, sell, exchange, or convert tokens, or bridge cross-chain. Covers full swap flow: price quotes, transaction build, signing, and submission. Do NOT use for read-only data lookups or wallet account management.
hunch
IncludedDiscover, bet on, track, and settle Hunch prediction markets in natural language. Trigger when a user wants to bet, take a position, or get odds on a crypto outcome — token market-cap milestones and flips, launchpad races (Bankr vs pump.fun volume / #1-days / launches over a cap), token head-to-head outperformance, mcap strike-ladders, and up/down price rounds. Also trigger on "what can I bet on about $TOKEN", "odds on …", "take YES/NO on …", "show my Hunch bets", "did my market resolve". Settles in USDC on Base via x402 (≤ $10 / bet); every bet returns an on-chain proof.
opensea
IncludedQuery NFT data, trade on the Seaport marketplace, and swap ERC20 tokens across Ethereum, Base, Arbitrum, Optimism, Polygon, and more.
polymarket
IncludedTrade on Polymarket prediction markets (CLOB V2) from a Privy EOA wallet. Search markets, place/cancel orders, manage positions. No private key handling. Use when the user wants to bet on event outcomes (e.g. "buy YES at 0.65 on the ceasefire market", "what are my open positions", "close my Trump bet").
