Build GitHub Action: NEAR Contract Deploy & Verify

Overview

Create a GitHub Action that deploys NEAR smart contracts to testnet/mainnet with verification, making deployments reproducible and auditable.

Why This Matters

CI/CD for smart contracts is essential for serious projects. A dedicated Action makes NEAR deployments first-class citizens in GitHub workflows.

Technical Requirements

Action Usage

name: Deploy Contract

on:
  push:
    branches: [main]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Build Contract
        run: cargo build --release --target wasm32-unknown-unknown

      - name: Deploy to NEAR
        uses: near-actions/deploy-contract@v1
        with:
          network: mainnet  # or testnet
          account-id: mycontract.near
          private-key: ${{ secrets.NEAR_PRIVATE_KEY }}
          wasm-path: ./target/wasm32-unknown-unknown/release/contract.wasm

          # Optional: Initialize contract
          init-method: new
          init-args: '{"owner_id": "admin.near"}'

          # Optional: Verify deployment
          verify: true

Features

1. Multi-network support - testnet, mainnet
2. Contract initialization - Call init method after deploy
3. Verification - Confirm code hash matches expected
4. Output variables - tx_hash, contract_id, code_hash
5. Upgrade support - Safe upgrade with migration call

Outputs

outputs:
  transaction-hash: ${{ steps.deploy.outputs.tx-hash }}
  explorer-url: ${{ steps.deploy.outputs.explorer-url }}
  code-hash: ${{ steps.deploy.outputs.code-hash }}

Deliverables

1. GitHub Action published to Marketplace
2. Support for Rust and AssemblyScript contracts
3. Complete documentation with examples
4. Error handling with helpful messages
