resolvePrivateKey(["solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution","solution"]);

Resolve Transaction Hash

Provide a cborTx, resolveTxHash will return the transaction hash. This hash is useful for creating chain transactions.

Resolve Transaction Hash

Convert transaction cborTx to transaction hash

const tx = new Transaction({ initiator: wallet });
tx.sendLovelace('addr_test1vpvx0sacufuypa2k4sngk7q40zc5c4npl337uusdh64kv0c7e4cxr', '1500000');

const unsignedTx = await tx.build();
const hash1 = resolveTxHash(unsignedTx);

const signedTx = await wallet.signTx(unsignedTx, false);
const hash2 = resolveTxHash(signedTx);

const txHash = await wallet.submitTx(signedTx);

// txHash == hash1 == hash2

Resolve Data Hash

Converts datum into hash. Getting the hash is useful when you need to query for the UTXO that contain the assets you need for your transaction's input.

Explore Transaction to learn more about designing Datum, and learn how to query for UTXOs containing the datum hash.

Resolve Data Hash

Convert datum into hash

Datum: supersecretdatum

resolveDataHash('supersecretdatum');

Resolve Native Script Hash

Converts NativeScript into hash.

Resolve Native Script Hash

Convert NativeScript to hash

Address addr_test1vpvx0sacufuypa2k4sngk7q40zc5c4npl337uusdh64kv0c7e4cxr

const keyHash = resolvePaymentKeyHash('addr_test1vpvx0sacufuypa2k4sngk7q40zc5c4npl337uusdh64kv0c7e4cxr');

const nativeScript: NativeScript = {
  type: "all",
  scripts: [
    {
      type: "sig",
      keyHash: keyHash,
    },
  ],
};

resolveNativeScriptHash(nativeScript);

Resolve Script Hash

resolveScriptHash will return a script hash. For example, this is useful when you want to convert a script to a policy ID.

Resolve Script Hash

Convert script to hash (like policy ID)

script address 8200581c5867c3b8e27840f556ac268b781578b14c5661fc63ee720dbeab663f

resolveScriptHash('8200581c5867c3b8e27840f556ac268b781578b14c5661fc63ee720dbeab663f')

Resolve Stake Address

Provide a wallet address, and resolveRewardAddress will return a staking address in bech32 format.

Resolve Stake Address

Convert wallet address to staking address

Address addr_test1qpvx0sacuf...swx9

resolveRewardAddress('addr_test1qpvx0sacufuypa2k4sngk7q40zc5c4npl337uusdh64kv0uafhxhu32dys6pvn6wlw8dav6cmp4pmtv7cc3yel9uu0nq93swx9');

Resolve Fingerprint

Takes policy ID and asset name, and return asset fingerprint based on CIP-14.

Resolve Asset Fingerprint

Convert asset policy ID and asset name to asset fingerprint.

Policy ID 426117329844ccb3b0ba877220ff06a5bdf21eab3fb33e2f3a3f8e69

Asset Name 4d657368546f6b656e

resolveFingerprint(
  '426117329844ccb3b0ba877220ff06a5bdf21eab3fb33e2f3a3f8e69',
  '4d657368546f6b656e'
)

Resolve Stake Key Hash

Provide a stake address, and resolveStakeKeyHash will return the pub key hash of the stake address. This key hash is useful for building the NativeScript.

Resolve Stake Key Hash

Convert stake address to pub key hash

Address stake_test1uzw5mnt7g4xjgdqkfa80hrk7kdvds6sa4k0vvgjvlj7w8eskffj2n

resolveStakeKeyHash('stake_test1uzw5mnt7g4xjgdqkfa80hrk7kdvds6sa4k0vvgjvlj7w8eskffj2n');

Resolve Rep Id

Resolve Rep Id from scrip hash.

Resolve Rep Id

Resolve rep id from scrip hash

let script: NativeScript = {
    type: "all",
    scripts: [
      {
        type: "sig",
        keyHash: 'aa048e4cc8a1e67e1d97ffbd4be614388014cbc2b2451527202943b6'
      },
    ],
  };

resolveScriptHashDRepId(resolveNativeScriptHash(script));

Resolve Epoch Number

With resolveEpochNo, you can get the current epoch with:

import { resolveEpochNo } from '@meshsdk/core';
const epoch = resolveEpochNo('preprod');

You can also provide date in milliseconds to get epoch in the past or the future. For example, get the epoch 1 year from now:

import { resolveEpochNo } from '@meshsdk/core';
let oneYearFromNow = new Date();
oneYearFromNow.setFullYear(oneYearFromNow.getFullYear() + 1);
const epoch = resolveEpochNo('preprod', oneYearFromNow.getTime());

Resolve Epoch number

Get the epoch number for the network

Select network preprod

resolveEpochNo('preprod');

Resolve Epoch number 1 year from now

Get the epoch number for the network 1 year from now

Select network preprod

let oneYearFromNow = new Date()
oneYearFromNow.setFullYear(oneYearFromNow.getFullYear() + 1);
resolveEpochNo(userInput, oneYearFromNow.getTime());

Resolve Slot Number

With resolveSlotNo, you can get the current slot number with:

import { resolveSlotNo } from '@meshsdk/core';
const slot = resolveSlotNo('preprod');

You can also provide date in milliseconds to get slots in the past or the future. For example, get the slot number 1 year from now:

import { resolveSlotNo } from '@meshsdk/core';
let oneYearFromNow = new Date();
oneYearFromNow.setFullYear(oneYearFromNow.getFullYear() + 1);
const slot = resolveSlotNo('preprod', oneYearFromNow.getTime());

Resolve Slot number

Get the Slot number for the network

Select network preprod

resolveSlotNo('preprod');

Resolve Slot number 1 year from now

Get the Slot number for the network 1 year from now

Select network preprod

let oneYearFromNow = new Date()
oneYearFromNow.setFullYear(oneYearFromNow.getFullYear() + 1);
resolveSlotNo(userInput, oneYearFromNow.getTime());
