Predicate Template by Olta Labs

This repository contains base to create a project around predicates.

Differents modules

• src containing the source code of the predicate
• typescript_interactions containing code to make interactions with the predicate in Typescript
• rust_interactions containing code to make interactions with the predicate in Rust

Steps

1. Compile the Predicate

forc build

2. Launch a local node

Download the source code from : https:/FuelLabs/fuel-core

Be careful, maybe the Rust SDK or Fuel SDK are supposed to be used with a certain version, if you encouter versions error in the futur, stop your node, checkout to tag v0.xx.x.

Launch a node with a consensus key to build a block :

cargo run --bin fuel-core -- --db-type in-memory --consensus-key 9e24cfa071f6c1c4984a17ecf18061a8d0c9c304e7dd7703788bd122bd578650

3. Interact with the predicate (using Typescript)

Go to typescript_interactions folder.

Install dependencies :

npm i

Run the script that will interact with the predicate :

npm run start

3. Interact with the predicate (using Rust)

Go to rust_interactions folder.

Run the script that will interact with the predicate :

PREDICATE_BINARY_PATH=../out/debug/predicate.bin cargo run
