A local, instant, zero-config Secret Network blockchain.

What Is LocalSecret?

LocalSecret is a complete Secret Network testnet and ecosystem containerized with Docker. It simplifies the way secret contract developers test their contracts in a sandbox before they deploy them on a testnet or mainnet.
LocalSecret comes preconfigured with opinionated, sensible defaults for standard testing environments. If other projects mention testing on LocalSecret, they are referring to the settings defined in this repo.

Advantages Of LocalSecret Vs. A Public Testnet

  1. 1.
    Easily modifiable world states
  2. 2.
    Quick to reset for rapid iterations
  3. 3.
    Simple simulations of different scenarios
  4. 4.
    Controllable validator behavior


  • Docker
  • Supported known architectures: x86_64, amd64

Install LocalSecret

docker pull

Start LocalSecret

x86 (Intel/AMD)
ARM (Mac M1)
docker run -it -p 9091:9091 -p 26657:26657 -p 1317:1317 -p 5000:5000 \
--name localsecret
Unfortunately, even LocalSecret inside a docker cannot be run on an M1 Mac. This is due to requiring SGX which can only work on x86 processors. As a workaround, we recommend using a LocalSecret instance in a Gitpod environment.
This environment is set up in such a way that can be accessed remotely as well.
To get started, simply click here.
To connect, prepend the port number with the Gitpod URL. e.g., if my workspace is at then I would be able to connect to the RPC service at
In order to follow the guide, simply replace the localhost endpoint with your own.
e.g., Instead of http://localhost:26657 you will be using
In addition, the chain-id for this LocalSecret instance will be secret-testnet-1 and not secretdev-1
You've now officially created a local Secret Network testnet with chain-id secretdev-1. 🎉
Your environment now contains:
secretcli, Keplr, cosmjs
[email protected] (deprecated)
SCRT Faucet
To get SCRT
secretjs, Keplr, [email protected] (deprecated)
You can also use docker run --rm to launch LocalSecret. This will delete the container once you exit the terminal, but it also means that you can't edit the node's config as stopping the container automatically deletes it.


Here are some examples of how to use LocalSecret with secretcli, secret.js, and Keplr.

Access And Configure Secretcli

To access secretcli from inside the docker container:
docker exec -it localsecret secretcli [command]
To configure & test your local secretcli binary:
secretcli config chain-id secretdev-1
secretcli config node http://localhost:26657
secretcli config output json
SGX_MODE=SW secretcli status
The environment variable SGX_MODE=SW must be applied when using a local secretcli binary.

Faucet (AKA Getting SCRT)

To send some SCRT to the example secret address secret1e6mqxtwgaps7vz3qfa3fcekhh7a02hvfjvtqpt we have to options:

Using The Faucet On Port 5000

curl "http://localhost:5000/faucet?address=${ADDRESS}"
The faucet drips 1000 SCRT at a time.

Using A Genesis Account

Inside the docker container there are accounts a, b, c & d that are pre-seeded with SCRT and can be used to send some to your address.
docker exec -it localsecret secretd tx bank send a ${ADDRESS} 1000000000uscrt -y

Connect To LocalSecret With secret.js

Connect to the chain through LocalSecret's LCD endpoint.
npm i secretjs or yarn add secretjs, then:
import { SecretNetworkClient } from "secretjs";
const secretjs = new SecretNetworkClient({
chainId: "secretdev-1",
url: "http://localhost:1317",


To add a custom chain to Keplr, use this code:
await window.keplr.experimentalSuggestChain({
chainId: "secretdev-1",
chainName: "LocalSecret",
rpc: "http://localhost:26657",
rest: "http://localhost:1317",

Different instances of LocalSecret need to be re-added to Keplr, so you need to first delete the old LocalSecret from Keplr and then re-run this^ code to add the current LocalSecret.

Configure LocalSecret

Modifying Node Configuration

You can modify the node configuration of your validator in the ~/.secretd/config/config.toml and ~/.secretd/config/app.toml files inside the container.
To enter the docker container to access them, run:
docker exec -it localsecret bash
You can then use commands like sed & perl to edit these files, or install text editors like vim & nano using apt install -y vim nano.

Applying The Changes

To apply changes that are made to the config file, restart LocalSecret by running:
docker stop localsecret
docker start -a localsecret

Speed Up Block Time

LocalSecret is often used alongside a script written with the secret.js as a convenient way to do integration tests. You can greatly improve the experience by speeding up the block time.
To decrease block times, run LocalSecret with the FAST_BLOCKS=true environment varibale:
docker run -it -e FAST_BLOCKS=true -p 9091:9091 -p 26657:26657 -p 1317:1317 -p 5000:5000 \
--name localsecret
To complement this, when testing with secret.js you can lower broadcastCheckIntervalMs to 100 from the default of 6000 (example).


LocalSecret is pre-configured with one validator and 4 accounts with SCRT balances. You can import them into your own testing environment for easier prototyping.
