Usage
Sign using the Ledger
import Ledger from "@colorplatform/color-ledger"
const signMessage = ... message to sign, generate messages with "@lunie/Cosmos-js"
const ledger = await Ledger().connect()
const signature = await ledger.sign(signMessage)
Using with Color-js
import Ledger from "@colorplatform/color-ledger"
import Color from "@lunie/Cosmos-js"
const privateKey = Buffer.from(...)
const publicKey = Buffer.from(...)
// init Color sender
const Color = Color(STARGATE_URL, ADDRESS)
// create message
const msg = Color
.MsgSend({toAddress: 'Color1abcd09876', amounts: [{ denom: 'stake', amount: 10 }})
// create a signer from this local js signer library
const ledgerSigner = async (signMessage) => {
const ledger = await Ledger().connect()
const publicKey = await ledger.getPubKey()
const signature = await ledger.sign(signMessage)
return {
signature,
publicKey
}
}
// send the transaction
const { included }= await msg.send({ gas: 200000 }, ledgerSigner)
// await tx to be included in a block
await included()
