//! # `op-crypto-extra` — extended crypto rails
|
|
//!
|
|
//! `op-rails-crypto` is the minimum-viable production stablecoin
|
|
//! rail: USDC / EURC / PYUSD on a handful of chains, ERC-20
|
|
//! `transfer`, JSON-RPC broadcast, hot-wallet signer. This crate
|
|
//! covers the *rest* of the modern crypto-payments surface:
|
|
//!
|
|
//! - **Stablecoin catalog.** A canonical [`stable::Stablecoin`] enum
|
|
//! covering USDC, USDT, PYUSD, DAI, RLUSD, EURC, FDUSD and their
|
|
//! well-known deployments across Ethereum L1, the dominant
|
|
//! L2 stack (Optimism, Arbitrum, Base, zkSync Era, Polygon zkEVM,
|
|
//! Linea, Scroll, Starknet), Polygon PoS, and Solana.
|
|
//! - **L2 topology.** [`chains`] enumerates each L2 with its
|
|
//! EIP-155 chain id, parent settlement layer, finality model, and
|
|
//! a default public RPC. Used by operators that want to register
|
|
//! one EVM-rail gateway per chain without hard-coding the list.
|
|
//! - **Account abstraction.** [`erc4337`] models the ERC-4337
|
|
//! `UserOperation` (v0.7 packed layout) and EntryPoint hand-off;
|
|
//! [`eip7702`] models the EIP-7702 "set-code" authorization that
|
|
//! lets an EOA temporarily execute as a smart account.
|
|
//! - **Permits.** [`permit2`] encodes Uniswap's Permit2 transfer
|
|
//! intents (single + batch + `PermitWitnessTransferFrom`).
|
|
//! [`eip2612`] encodes the older ERC-2612 `permit(...)` typed
|
|
//! data for token approvals without on-chain `approve`.
|
|
//! - **Cross-chain.** [`cctp`] models Circle's CCTP v2 burn / mint
|
|
//! message (`depositForBurn` + Attestation + `receiveMessage`)
|
|
//! for native cross-chain USDC.
|
|
//! - **Lightning.** [`lightning`] parses BOLT-11 invoices (bech32
|
|
//! sanity-check + tagged-field walk) and validates LNURL
|
|
//! bech32-encoded URLs.
|
|
//! - **Bitcoin.** [`psbt`] is a thin PSBT v2 sketch (BIP-370
|
|
//! field layout — global / input / output map keys) suited for
|
|
//! round-tripping unsigned Bitcoin transactions through a
|
|
//! third-party signer.
|
|
//! - **Atomic swap.** [`htlc`] models the hash-time-lock contract
|
|
//! primitive used in cross-chain swaps (single-secret HTLC with
|
|
//! chain-agnostic field layout).
|
|
//! - **Confidential transfer.** [`confidential`] sketches the
|
|
//! structural surface of confidential-token transfers (Solana
|
|
//! confidential token / Aleo / Aztec) — the public field, the
|
|
//! ciphertext envelope, and the proof envelope — without
|
|
//! committing to a specific zk system.
|
|
//!
|
|
//! ## Scope
|
|
//!
|
|
//! Like `op-rails-crypto`, this crate is **rail-agnostic at the
|
|
//! chain level**. It does not bundle any chain SDK or signer. The
|
|
//! types model the *wire layout* of each primitive precisely enough
|
|
//! that an operator's signer / broadcaster can produce real
|
|
//! transactions; the broadcast itself happens elsewhere (operator's
|
|
//! KMS, Fireblocks, Lightning daemon, Bitcoin Core, etc.).
|
|
//!
|
|
//! ## What this crate does NOT do
|
|
//!
|
|
//! - **No signing.** Every primitive ends in a "build me the bytes
|
|
//! to be signed" boundary.
|
|
//! - **No bridging.** CCTP message construction is included
|
|
//! because it's a Circle-issued message format; live attestation
|
|
//! fetching against Circle's API is the operator's job.
|
|
//! - **No price feeds.** Stablecoins are 1:1 by design.
