Wallet

You can instantiate a wallet object from seed without binding it with a Lucid object by calling the walletFromSeed() function. For example, to use it with an emulator or to run test scenarios.

Steps to Create a Wallet

Generate Seed Phrase


import { generateSeedPhrase } from "@evolution-sdk/lucid";
 
const seedPhrase = generateSeedPhrase(); // BIP-39
console.log(seedPhrase);

Create Wallet


import { walletFromSeed } from "@evolution-sdk/lucid";
 
const seedPhrase = "your seed phrase here ...";
const wallet = walletFromSeed(seedPhrase);
console.log(wallet); // { address, rewardAddress, paymentKey, stakeKey }

Utility Functions

Discover Used Key Hashes

To discover which key hashes are used in a transaction, limited by the specified UTxOs, you can use the discoverOwnUsedTxKeyHashes() function:


import { discoverOwnUsedTxKeyHashes } from "@evolution-sdk/lucid";
 
const tx: TxSignBuilder = await lucid
  .newTx()
  // ... build your transaction
  .complete();
const ownKeyHashes: Array<KeyHash> = ["KeyHash1", "KeyHash2", "OtherKeyHash"];
const ownUtxos: Array<UTxO> = utxos;
 
const usedKeyHashes: Array<KeyHash> = discoverOwnUsedTxKeyHashes(
  tx.toTransaction(),
  ownKeyHashes,
  ownUtxos,
);
console.log(usedKeyHashes); // ["KeyHash1", "KeyHash2"]
