Willow Emberdock (Built for Base)

Willow Emberdock is a browser-based Base diagnostic surface focused on fast verification rather than abstraction. It connects a Coinbase Wallet, validates Base chain identity, and exposes public onchain state in a transparent, read-only manner.

What this project is about

This repository exists to support lightweight Base validation flows:

• Confirm Base RPC reachability
• Verify chainId responses (8453 / 84532)
• Inspect balances and transaction counts
• Review recent block activity
• Cross-check data using Basescan

It is intentionally minimal and safe to run.

Repository layout

• app/willow-emberdock.ts
  Browser entry script that performs wallet connection and read-only RPC queries.

• config/base.networks.json
  Static Base network definitions including RPC endpoints and explorers.

• scripts/sample-inputs.json
  Example addresses for repeatable read-only checks.

• contracts/
  Solidity contracts deployed to Base Sepolia for testnet validation:

  • errors.sol — improves safety and reduces gas costs
  • ERC20.sol — tracks balances and total supply

• package.json
  Dependency manifest referencing Base and Coinbase repositories.

• README.md
  Primary technical documentation.

Network scope

Base Sepolia
chainId (decimal): 84532

Base Mainnet
chainId (decimal): 8453

Tooling references

This project intentionally pulls from official ecosystems:

• Coinbase Wallet SDK for EIP-1193 wallet connectivity
• OnchainKit references for Base-aligned primitives
• viem for typed, efficient read-only RPC access
• Multiple Base and Coinbase GitHub repositories as dependencies

Testnet Deployment (Base Sepolia)

As part of pre-production validation, one or more contracts may be deployed to the Base Sepolia test network to confirm correct behavior and tooling compatibility.

Network: Base Sepolia

Deployment and verification:

• https://sepolia.basescan.org/address/0xfdc56D5CfD61da5d3d2d4Fd09315fA0E3DDF0dbD
• https://sepolia.basescan.org/0xfdc56D5CfD61da5d3d2d4Fd09315fA0E3DDF0dbD/0#code

These testnet deployments provide a controlled environment for validating Base tooling, account abstraction flows, and read-only onchain interactions prior to Base Mainnet usage.
