What it does
Coin Modules is an agent skill from LedgerHQ/ledger-live. Rules and layout for coin module packages under libs/coin-modules/. Read when adding or modifying a coin module.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Mono-repository for Ledger Wallet apps and related packages. The licence is MIT.
Example prompts
- “Use the coin-modules skill to rule and layout for coin module packages under libs/coin-modules/”
- “/coin-modules”
What it can do on your machine
Read from SKILL.md and the folder at commit 30d7883. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Coin Modules loads about 1.1k tokens when it runs. Until then it costs about 31 tokens; SKILL.md has 346 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Coin Modules
Each blockchain family lives in its own package under libs/coin-modules/coin-<family>.
Package name: @ledgerhq/coin-<family>
Coin modules are one of the few things that still belong in legacy libs/: they migrate to
LedgerHQ/coin-modules, not to the monorepo layers.
Do not create a new coin-module if it fits the ecosystem of an existing one.
No packages other than coin-modules are allowed in libs/coin-modules/.
Directory Layout
| Directory / file | Purpose |
|---|---|
api/ | Coin Module API surface — implements CoinModuleApi from @ledgerhq/coin-module-framework/api/index; restricted imports apply (see below) |
logic/ | Core blockchain logic, agnostic of Bridge or API; only depends on network/ and external libs; restricted imports apply (see below) |
network/ | Communication with explorer / indexer / node; restricted imports apply (see below) |
types/ | Model definitions, not related to network |
bridge/ (legacy) | CurrencyBridge + AccountBridge implementation |
signer/ (legacy) | Hardware wallet signer interface and device address resolver |
Tests: *.unit.test.ts (co-located), *.test.ts (integration, no network), *.integ.test.ts (real network, separate jest.integ.config.js).
Dependencies
Prefer native dependencies from the blockchain foundation and well-established open-source libraries.
Avoid proprietary third-party SDKs or closed-source vendor packages.
In api/, logic/, and network/, the only permitted @ledgerhq/* imports are @ledgerhq/logs, @ledgerhq/live-network, @ledgerhq/coin-module-framework, and @ledgerhq/ledger-wallet-framework (enforced by eslint/no-restricted-imports in libs/coin-modules/.oxlintrc.json). Other directories (bridge/, signer/, types/) have no such restriction.
Integration Paths
1. Coin Module API path (preferred) — export createApi(config, currencyId) returning CoinModuleApi (from @ledgerhq/coin-module-framework/api/index). Enable the family in libs/ledger-live-common/src/bridge/generic-coin-framework/genericCoinFrameworkFamilies.json (checked by isGenericCoinFrameworkFamily). For methods that don't apply, throw new Error("<method> is not supported").
2. Classic JS Bridge (legacy, do not use) — export createBridges(signerContext, coinConfig) returning { currencyBridge, accountBridge }. Wired via libs/ledger-live-common/src/families/<family>/setup.ts.
Integ Test Requirements (Coin Module API)
craftTransaction/estimateFees: cover each transaction type (token transfer, native, memo, delegation, …)getBalance/listOperations: cover each asset type in the modulegetBlockInfo/getBlock/listOperations/getStakes: compare against a reference block/op/stake to validate metadata parsinggetValidators: validate metadata against a reference validatorlastBlock: block height > 0, valid date, hash with expected lengthgetNextSequence: higher than current nonce for a known account
live-common Import Rule
In libs/ledger-live-common/src, runtime imports of coin-specific code (from @ledgerhq/coin-* or ../families/*) are only allowed inside src/coin-modules/ and src/families/. All other shared code must access coin-specific behaviour through coinModuleLoaders from src/coin-modules/loaders.ts.
