+# Wallet-Relevant EIPs And ERCs
+
+This is Deckard's implementation-oriented shortlist, curated from the canonical
+[`ethereum/EIPs`](https://github.com/ethereum/EIPs) and
+[`ethereum/ERCs`](https://github.com/ethereum/ERCs) repositories.
+
+Keep rules:
+
+- Keep Final EIPs.
+- Keep Final ERCs that appear in `ethereum/EIPs` as moved ERC stubs.
+- Keep a small number of Stagnant Interface EIPs only when they are de facto wallet/dapp APIs
+  already expected by the ecosystem.
+- Drop Draft, Withdrawn, Last Call, purely historical, and not-yet-actionable specs from the
+  implementation tables.
+
+Implementation importance is rated for a desktop self-custodial Ethereum wallet whose dapp
+communication surface is a browser extension. `Critical` means the extension bridge or
+transaction/signing core should support it directly. `High` means expected for a competitive
+production wallet. `Medium` means useful or ecosystem-dependent. `Low` means optional.
+

+## Kohaku Wallet References
+
+These entries are not EIPs/ERCs. Keep them as implementation references for Deckard's privacy and
+browser-extension architecture, not as standards targets.
+
+| Category | Title | Source | Wallet relevance | Implementation importance | Additional notes |
+| --- | --- | --- | --- | --- | --- |
+| Architecture | Privacy-first Ethereum tooling | [kohaku/README.md](https://github.com/ethereum/kohaku/blob/master/README.md) | Positions Kohaku as reusable wallet infrastructure for privacy-preserving Ethereum UX. | High | Production integration still needs security review for each reused package. |
+| Dapp bridge | EIP-1193 provider abstraction | [kohaku/crates/eip-1193-provider/README.md](https://github.com/ethereum/kohaku/blob/master/crates/eip-1193-provider/README.md), [kohaku/packages/provider/README.md](https://github.com/ethereum/kohaku/blob/master/packages/provider/README.md) | Useful for keeping the browser extension provider thin while routing requests into native, WASM, Ethers, Viem, Helios, or Colibri backends. | Critical | Fits the desktop-wallet model where the extension is only the dapp transport and the desktop app owns policy, accounts, and signing. |
+| Privacy infrastructure | Private RPC and light-client posture | [kohaku/docs/pages/practices.mdx](https://github.com/ethereum/kohaku/blob/master/docs/pages/practices.mdx), [kohaku/docs/pages/privacy.mdx](https://github.com/ethereum/kohaku/blob/master/docs/pages/privacy.mdx) | Reduces wallet activity leakage from default RPCs and centralized indexing. | High | Kohaku docs call out user-defined RPCs, Helios-style verification, and optional network privacy routing as wallet best practices. |
+| Account UX | Many accounts, many identities | [kohaku/docs/pages/practices.mdx](https://github.com/ethereum/kohaku/blob/master/docs/pages/practices.mdx), [kohaku/docs/pages/privacy.mdx](https://github.com/ethereum/kohaku/blob/master/docs/pages/privacy.mdx) | Encourages per-context accounts and easy account creation during dapp connection. | High | This should influence the extension connect flow: choosing or creating an account should be part of the permission grant, not only a global wallet setting. |
+| Plugin system | Standardized private-transaction plugin interface | [kohaku/packages/plugins/README.md](https://github.com/ethereum/kohaku/blob/master/packages/plugins/README.md) | Lets the wallet expose shield, transfer, unshield, balance, and broadcast flows across multiple privacy protocols through one host interface. | High | Host responsibilities include storage, network fetch, keystore derivation, and Ethereum provider access; this maps cleanly to a desktop wallet core. |
+| Key management | Portable plugin key derivation | [kohaku/packages/plugins/README.md](https://github.com/ethereum/kohaku/blob/master/packages/plugins/README.md) | Allows privacy protocol keys to derive from the wallet mnemonic where supported. | High | Imported plugin key material is not automatically portable, so backup and sync UX must explicitly include plugin state or imported secrets. |
+| Shielded assets | Railgun shielded-pool support | [kohaku/docs/pages/railgun/intro.mdx](https://github.com/ethereum/kohaku/blob/master/docs/pages/railgun/intro.mdx), [kohaku/crates/railgun/README.md](https://github.com/ethereum/kohaku/blob/master/crates/railgun/README.md) | Adds shielding, internal transfer, and unshielding for ERC-20 assets and ETH via WETH-style wrapping. | Medium | Useful as a wallet feature area, but protocol risk, circuit artifacts, indexing, and compliance posture need separate review before default exposure. |
+| Account abstraction | ERC-4337 UserOperation kit | [kohaku/crates/userop-kit/README.md](https://github.com/ethereum/kohaku/blob/master/crates/userop-kit/README.md) | Provides UserOperation building and bundler client support for EntryPoint 0.7 and 0.8. | High | Important if the desktop wallet plans smart accounts, paymasters, sponsored transactions, or batched dapp actions. |
+| Asset privacy | Local token discovery caution | [kohaku/docs/pages/privacy.mdx](https://github.com/ethereum/kohaku/blob/master/docs/pages/privacy.mdx) | Pushes the wallet away from centralized all-transfer-event indexing that links addresses to lookup behavior. | High | Prefer local indexing, user-configured indexers, light-client verification, or explicit opt-in discovery modes. |
