@ledgerhq/hw-app-solana

Ledger Hardware Wallet Solana JavaScript bindings.

Are you adding Ledger support to your software wallet?

You may be using this package to communicate with the Solana Nano App.

For a smooth and quick integration:

• See the developers’ documentation on the Developer Portal and
• Go on Discord to chat with developer support and the developer community.

Notes

To run speculos-smoke test make sure Speculos running (apdu port 9999 and api rest endpoint http://0.0.0.0:5000) with Solana app installed on it. Then run the command from root workspace:

$ yarn run ts-node packages/hw-app-solana/tests/speculos-smoke.ts

Troubleshooting

If ledger returns error 6808 - enable blind signature in settings (not needed for unit testing).

Solana

Solana API

Parameters

• transport Transport a transport for sending commands to a device
• scrambleKey string a scramble key (optional, default "solana_default_scramble_key")

Examples

import Solana from "@ledgerhq/hw-app-solana";
const solana = new Solana(transport);

getAddress

Get Solana address (public key) for a BIP32 path.

Because Solana uses Ed25519 keypairs, as per SLIP-0010 all derivation-path indexes will be promoted to hardened indexes.

Parameters

• path string a BIP32 path
• display boolean flag to show display (optional, default false)

Examples

solana.getAddress("44'/501'/0'").then(r => r.address)

Returns Promise<{address: Buffer}> an object with the address field

signTransaction

Sign a Solana transaction.

Parameters

• path string a BIP32 path
• txBuffer Buffer serialized transaction

Examples

solana.signTransaction("44'/501'/0'", txBuffer).then(r => r.signature)

Returns Promise<{signature: Buffer}> an object with the signature field

signOffchainMessage

Sign a Solana off-chain message.

Parameters

• path string a BIP32 path
• msgBuffer Buffer serialized off-chain message

Examples

solana.signOffchainMessage("44'/501'/0'", msgBuffer).then(r => r.signature)

Returns Promise<{signature: Buffer}> an object with the signature field

getAppConfiguration

Get application configuration.

Examples

solana.getAppConfiguration().then(r => r.version)

Returns Promise\ application config object

getChallenge

Method returning a 4 bytes TLV challenge as an hex string

Returns Promise[string](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String)

provideTrustedName

Provides a trusted name to be displayed during transactions in place of the token address it is associated to. It shall be run just before a transaction involving the associated address that would be displayed on the device.

Parameters

• data string a stringified buffer of some TLV encoded data to represent the trusted name

Returns Promise[boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean) a boolean
