Beta Version Notice

This library is still in beta, APIs may break. Beta testers are welcome!

See project board for list of existing/missing features.

Installation

npm install secretjs

or

yarn add secretjs

Usage Examples

Note: Public gRPC-web endpoints can be found in https://github.com/scrtlabs/api-registry for both mainnet and testnet.

For a lot more usage examples refer to the tests.

Sending Queries

import { SecretNetworkClient, grpc } from "secretjs";

const grpcWebUrl = "TODO get from https://github.com/scrtlabs/api-registry";

// To create a readonly secret.js client, just pass in a gRPC-web endpoint
const secretjs = await SecretNetworkClient.create({
grpcWebUrl,
chainId: "secret-4",
});

const {
balance: { amount },
} = await secretjs.query.bank.balance(
{
address: "secret1ap26qrlp8mcq2pg6r47w43l0y8zkqm8a450s03",
denom: "uscrt",
} /*,
// optional: query at a specific height (using an archive node)
new grpc.Metadata({"x-cosmos-block-height": "2000000"})
*/,
);

console.log(`I have ${Number(amount) / 1e6} SCRT!`);

const sSCRT = "secret1k0jntykt7e4g3y88ltc60czgjuqdy4c9e8fzek";
// Get codeHash using `secretcli q compute contract-hash secret1k0jntykt7e4g3y88ltc60czgjuqdy4c9e8fzek`
const sScrtCodeHash =
"af74387e276be8874f07bec3a87023ee49b0e7ebe08178c49d0a49c3c98ed60e";

const { token_info } = await secretjs.query.compute.queryContract({
contractAddress: sSCRT,
codeHash: sScrtCodeHash, // optional but way faster
query: { token_info: {} },
});

console.log(`sSCRT has ${token_info.decimals} decimals!`);

Broadcasting Transactions

import { Wallet, SecretNetworkClient, MsgSend, MsgMultiSend } from "secretjs";

const wallet = new Wallet(
"grant rice replace explain federal release fix clever romance raise often wild taxi quarter soccer fiber love must tape steak together observe swap guitar",
);
const myAddress = wallet.address;

const grpcWebUrl = "TODO get from https://github.com/scrtlabs/api-registry";

// To create a signer secret.js client, also pass in a wallet
const secretjs = await SecretNetworkClient.create({
grpcWebUrl,
chainId: "secret-4",
wallet: wallet,
walletAddress: myAddress,
});

const bob = "secret1dgqnta7fwjj6x9kusyz7n8vpl73l7wsm0gaamk";
const msg = new MsgSend({
fromAddress: myAddress,
toAddress: bob,
amount: [{ denom: "uscrt", amount: "1" }],
});

const tx = await secretjs.tx.broadcast([msg], {
gasLimit: 20_000,
gasPriceInFeeDenom: 0.1,
feeDenom: "uscrt",
});

Integrations

MetaMask

import { SecretNetworkClient, MetaMaskWallet } from "secretjs";

//@ts-ignore
const [ethAddress] = await window.ethereum.request({
method: "eth_requestAccounts",
});

const wallet = await MetaMaskWallet.create(window.ethereum, ethAddress);

const secretjs = await SecretNetworkClient.create({
grpcWebUrl: "TODO get from https://github.com/scrtlabs/api-registry",
chainId: "secret-4",
wallet: wallet,
walletAddress: wallet.address,
});

Notes:

  1. MetaMask supports mobile!
  2. MetaMask supports Ledger.
  3. Currently MetaMask doesn't support clear-text signing of transactions, meaning users will not see what they're signing on and MetaMask will show them a scary warning when signing (see image). This will be solved on Shockwave Delta upgrade (September 2022). Until then you might want to indicate this to users on your UI somehow.
  4. You might want to pass encryptionSeed to SecretNetworkClient.create() to use the same encryption key for the user across sessions. This value should be a true random 32 byte number that is stored securly in your app, such that only the user can decrypt it. This can also be a sha256(user_password) but might impair UX.
  5. See Keplr's getOfflineSignerOnlyAmino() for list of unsupported transactions.

Keplr Wallet

The recommended way of integrating Keplr is by using window.keplr.getOfflineSignerOnlyAmino():

import { SecretNetworkClient } from "secretjs";

const sleep = (ms: number) => new Promise((resolve) => setTimeout(resolve, ms));

while (
!window.keplr ||
!window.getEnigmaUtils ||
!window.getOfflineSignerOnlyAmino
) {
await sleep(50);
}

const CHAIN_ID = "secret-4";

await window.keplr.enable(CHAIN_ID);

const keplrOfflineSigner = window.keplr.getOfflineSignerOnlyAmino(CHAIN_ID);
const [{ address: myAddress }] = await keplrOfflineSigner.getAccounts();

const grpcWebUrl = "TODO get from https://github.com/scrtlabs/api-registry";

const secretjs = await SecretNetworkClient.create({
grpcWebUrl,
chainId: CHAIN_ID,
wallet: keplrOfflineSigner,
walletAddress: myAddress,
encryptionUtils: window.keplr.getEnigmaUtils(CHAIN_ID),
});

// Note: Using `window.getEnigmaUtils` is optional, it will allow
// Keplr to use the same encryption seed across sessions for the account.
// The benefit of this is that `secretjs.query.getTx()` will be able to decrypt
// the response across sessions.

Notes:

  1. No mobile support yet.
  2. Keplr supports Ledger.
  3. By using encryptionUtils you let Keplr handle user encryption keys for you, which allows you to easily decrypt transactions across sessions.

SignerOnlyAmino vs Signer vs SignerAuto

TLDR:

window.keplr.getOfflineSignerOnlyAmino()

Although this is the legacy way of signing transactions on cosmos-sdk, it's still the most recommended for connecting to Keplr due to Ledger support & better UI on Keplr.

Note that ibc_transfer/MsgTransfer for sending funds across IBC is supported.

window.keplr.getOfflineSigner()

The new way of signing transactions on cosmos-sdk, it's more efficient but still doesn't have Ledger support, so it's most recommended for usage in apps that don't require signing transactions with Ledger.

  • 🟥 Looks bad on Keplr
  • 🟥 Doesn't support users signing with Ledger
  • 🟩 Supports signing transactions with all types of Msgs

window.keplr.getOfflineSignerAuto()

If the connected Keplr account uses Ledger, returns window.keplr.getOfflineSignerOnlyAmino().
Otherwise returns window.keplr.getOfflineSigner().

Fina Wallet

Fina implements the Keplr API, so the above Keplr docs applies. If you support Keplr, your app will also work on the Fina Wallet mobile app. This works because the Fina Wallet mobile app has webview to which it injects its objects under window.keplr.

Links:

Leap Cosmos Wallet

Leap implements the Keplr API, so the above Keplr docs applies.

The recommended way of integrating Leap is by using window.leap.getOfflineSignerOnlyAmino():

import { SecretNetworkClient } from "secretjs";

const sleep = (ms: number) => new Promise((resolve) => setTimeout(resolve, ms));

while (
!window.leap ||
!window.leap.getEnigmaUtils ||
!window.leap.getOfflineSignerOnlyAmino
) {
await sleep(50);
}

const CHAIN_ID = "secret-4";

await window.leap.enable(CHAIN_ID);

const leapOfflineSigner = window.leap.getOfflineSignerOnlyAmino(CHAIN_ID);
const [{ address: myAddress }] = await leapOfflineSigner.getAccounts();

const grpcWebUrl = "TODO get from https://github.com/scrtlabs/api-registry";

const secretjs = await SecretNetworkClient.create({
grpcWebUrl,
chainId: CHAIN_ID,
wallet: leapOfflineSigner,
walletAddress: myAddress,
encryptionUtils: window.leap.getEnigmaUtils(CHAIN_ID),
});

// Note: Using `window.leap.getEnigmaUtils()` is optional, it will allow
// Leap to use the same encryption seed across sessions for the account.
// The benefit of this is that `secretjs.query.getTx()` will be able to decrypt
// the response across sessions.

API

Wallet

An offline wallet implementation, used to sign transactions. Usually we'd just want to pass it to SecretNetworkClient.

Full API »

Importing account from mnemonic

import { Wallet } from "secretjs";

const wallet = new Wallet(
"grant rice replace explain federal release fix clever romance raise often wild taxi quarter soccer fiber love must tape steak together observe swap guitar",
);
const myAddress = wallet.address;

Generating a random account

import { Wallet } from "secretjs";

const wallet = new Wallet();
const myAddress = wallet.address;
const myMnemonicPhrase = wallet.mnemonic;

SecretNetworkClient

Full API »

Querier secret.js

A querier client can only send queries and get chain information. Access to all query types can be done via secretjs.query.

import { SecretNetworkClient } from "secretjs";

const grpcWebUrl = "TODO get from https://github.com/scrtlabs/api-registry";

// To create a readonly secret.js client, just pass in a gRPC-web endpoint
const secretjs = await SecretNetworkClient.create({
chainId: "secret-4",
grpcWebUrl,
});

Signer secret.js

A signer client can broadcast transactions, send queries and get chain information.

Here in addition to secretjs.query, there are also secretjs.tx & secretjs.address.

import { Wallet, SecretNetworkClient, MsgSend, MsgMultiSend } from "secretjs";

const wallet = new Wallet(
"grant rice replace explain federal release fix clever romance raise often wild taxi quarter soccer fiber love must tape steak together observe swap guitar",
);
const myAddress = wallet.address;

const grpcWebUrl = "TODO get from https://github.com/scrtlabs/api-registry";

// To create a signer secret.js client you must also pass in `wallet`, `walletAddress` and `chainId`
const secretjs = await SecretNetworkClient.create({
grpcWebUrl,
chainId: "secret-4",
wallet: wallet,
walletAddress: myAddress,
});

secretjs.query

secretjs.query.getTx(hash)

Returns a transaction with a txhash. hash is a 64 character upper-case hex string.

secretjs.query.txsQuery(query)

Returns all transactions that match a query.

To tell which events you want, you need to provide a query. query is a string, which has a form: condition AND condition ... (no OR at the moment). Condition has a form: key operation operand. key is a string with a restricted set of possible symbols (\t, \n, \r, \, (, ), ", ', =, >, < are not allowed). Operation can be =, <, <=, >, >=, CONTAINS AND EXISTS. Operand can be a string (escaped with single quotes), number, date or time.

Examples:

  • tx.hash = 'XYZ' # single transaction
  • tx.height = 5 # all txs of the fifth block
  • create_validator.validator = 'ABC' # tx where validator ABC was created

Tendermint provides a few predefined keys: tx.hash and tx.height. You can provide additional event keys that were emitted during the transaction. All events are indexed by a composite key of the form {eventType}.{evenAttrKey}. Multiple event types with duplicate keys are allowed and are meant to categorize unique and distinct events.

To create a query for txs where AddrA transferred funds: transfer.sender = 'AddrA'

See txsQuery under https://secretjs.scrt.network/modules#Querier.

// To create a signer secret.js client, also pass in a wallet
const secretjs = await SecretNetworkClient.create({
grpcWebUrl,
chainId: "secret-4",
wallet: wallet,
walletAddress: myAddress,
});

const alsoMyAddress = secretjs.address;

secretjs.tx

On a signer secret.js, secretjs.tx is used to broadcast transactions. Every function under secretjs.tx can receive an optional TxOptions.

Full API »

secretjs.tx.broadcast()

Used to send a complex transactions, which contains a list of messages. The messages are executed in sequence, and the transaction succeeds if all messages succeed.

For a list of all messages see: https://secretjs.scrt.network/interfaces/Msg

const addMinterMsg = new MsgExecuteContract({
sender: MY_ADDRESS,
contractAddress: MY_NFT_CONTRACT,
codeHash: MY_NFT_CONTRACT_CODE_HASH, // optional but way faster
msg: { add_minters: { minters: [MY_ADDRESS] } },
sentFunds: [], // optional
});

const mintMsg = new MsgExecuteContract({
sender: MY_ADDRESS,
contractAddress: MY_NFT_CONTRACT,
codeHash: MY_NFT_CONTRACT_CODE_HASH, // optional but way faster
msg: {
mint_nft: {
token_id: "1",
owner: MY_ADDRESS,
public_metadata: {
extension: {
image: "https://scrt.network/secretnetwork-logo-secondary-black.png",
name: "secretnetwork-logo-secondary-black",
},
},
private_metadata: {
extension: {
image: "https://scrt.network/secretnetwork-logo-primary-white.png",
name: "secretnetwork-logo-primary-white",
},
},
},
},
sentFunds: [], // optional
});

const tx = await secretjs.tx.broadcast([addMinterMsg, mintMsg], {
gasLimit: 200_000,
});

secretjs.tx.simulate()

Used to simulate a complex transactions, which contains a list of messages, without broadcasting it to the chain. Can be used to get a gas estimation or to see the output without actually committing a transaction on-chain.

The input should be exactly how you'd use it in secretjs.tx.broadcast(), except that you don't have to pass in gasLimit, gasPriceInFeeDenom & feeDenom.

Notes:

  • :warning: On mainnet it's recommended to not simulate every transaction as this can burden your node provider. Instead, use this while testing to determine the gas limit for each of your app's transactions, then in production use hard-coded values.
  • Gas estimation is known to be a bit off, so you might need to adjust it a bit before broadcasting.
const sendToAlice = new MsgSend({
fromAddress: bob,
toAddress: alice,
amount: [{ denom: "uscrt", amount: "1" }],
});

const sendToEve = new MsgSend({
fromAddress: bob,
toAddress: eve,
amount: [{ denom: "uscrt", amount: "1" }],
});

const sim = await secretjs.tx.simulate([sendToAlice, sendToEve]);

const tx = await secretjs.tx.broadcast([sendToAlice, sendToEve], {
// Adjust gasLimit up by 10% to account for gas estimation error
gasLimit: Math.ceil(sim.gasInfo.gasUsed * 1.1),
});

secretjs.tx.authz.exec()

MsgExec attempts to execute the provided messages using authorizations granted to the grantee. Each message should have only one signer corresponding to the granter of the authorization.

Input: MsgExecParams

secretjs.tx.authz.exec.simulate()

Simulates execution without sending a transactions. Input is exactly like the parent function. For more info see secretjs.tx.simulate().

secretjs.tx.authz.grant()

MsgGrant is a request type for Grant method. It declares authorization to the grantee on behalf of the granter with the provided expiration time.

Input: MsgGrantParams

secretjs.tx.authz.grant.simulate()

Simulates execution without sending a transactions. Input is exactly like the parent function. For more info see secretjs.tx.simulate().

secretjs.tx.authz.revoke()

MsgRevoke revokes any authorization with the provided sdk.Msg type on the granter's account with that has been granted to the grantee.

Input: MsgRevokeParams

secretjs.tx.authz.revoke.simulate()

Simulates execution without sending a transactions. Input is exactly like the parent function. For more info see secretjs.tx.simulate().

secretjs.tx.bank.multiSend()

MsgMultiSend represents an arbitrary multi-in, multi-out send message.

Input: MsgMultiSendParams

coins: [{ denom: "uscrt", amount: "2" }],
},
],
outputs: [
{
address: alice,
coins: [{ denom: "uscrt", amount: "1" }],
},
{
address: bob,
coins: [{ denom: "uscrt", amount: "1" }],
},
],
},
{
gasLimit: 20_000,
},
);
##### `secretjs.tx.bank.multiSend.simulate()`

Simulates execution without sending a transactions. Input is exactly like the parent function. For more info see secretjs.tx.simulate().

Input: MsgSendParams

const tx = await secretjs.tx.bank.send(
{
fromAddress: myAddress,
toAddress: alice,
amount: [{ denom: "uscrt", amount: "1" }],
},
{
gasLimit: 20_000,
},
