Prerequisites

• Bun >= 1.2.21
• Chainlink CRE CLI

1. Install dependencies

Run from the project root directory:

bun install --cwd ./workflow-register

2. Fill in the TODOs

Search for TODO in the source files to find every placeholder.

• Fill in EVM function argument types and values in workflow.ts
• Update encodeAbiParameters to match your consumer contract's onReport param types

3. Simulate the workflow

Run from the project root directory:

cre workflow simulate workflow-register --target staging-settings

On .env, define CRE_ETH_PRIVATE_KEY. Use --broadcast to submit the transaction:

cre workflow simulate workflow-register --target=staging-settings --broadcast
