Deposit Demo

This test file in deposit.ts demonstrates how to use the transaction relayer to relay a deposit transaction.

Prerequisites

  1. You can use Bun or node.js to run the test file.
  2. Tangle Testnet running locally.
  3. This Relayer running locally at http://localhost:3000.

Running Tangle Testnet

  1. Compile the tangle testnet node using the following command:
cargo b -rp tangle --features txpool,testnet,manual-seal
  1. Run the tangle testnet node using the following command:
./target/release/tangle --tmp --dev --validator -linfo --alice --rpc-cors all --rpc-methods=unsafe --rpc-external --rpc-port 9944 -levm=debug -lg
adget=trace --sealing manual

Running the Relayer

  1. Clone this repository and then run the following commands:
cargo build
  1. Install the Tangle CLI if you haven't already:
cargo install cargo-tangle --force
  1. Insert the following key into the keystore:
mkdir -p target/keystore
cargo tangle blueprint keygen -k ecdsa -p target/keystore -s cb6df9de1efca7a3998a8ead4e02159d5fa99c3e0d4fd6432667390bb4726854
  1. Run the relayer using the following command:
RUST_LOG=gadget=debug,tower_http=debug,txrelayer_blueprint=debug ./target/debug/txrelayer-blueprint run --protocol tangle --blueprint-id 0 --service-id 0 --http-rpc-url http://localhost:9944 --ws-rpc-url ws://localhost:9944 --chain local_testnet --keystore-uri ./target/keystore

Running the Deposit Demo

Go to the tests directory and then:

  1. Install the dependencies using the following command:
npm install

or if you are using bun:

bun install
  1. Run the deposit demo using the following command:
bun deposit.ts
