Test on a local chain

The guides were written against a local-chain project: IdentityRegistry and HandleEscrow on anvil, with test verifiers that accept any binding without a proof, and a few test handles bound. That project is not published yet. Until it is, you can:

• run the read-only code against a public network, or
• deploy the full libID stack to anvil with libid-deploy. It starts with nothing bound.

Read from a public network

The code in the guides reads RPC_URL and IDENTITY_REGISTRY. Point them at Ethereum mainnet:

export RPC_URL=https://ethereum-rpc.publicnode.com
export IDENTITY_REGISTRY=0xbefd300aff7d4a67fb381afe8b3596793d3e9a83

See Networks for the others. The guides’ test handles and addresses are not bound there, so you get null or an empty list where a guide shows output. Use a handle or an address that has bound an identity instead.

Deploy the stack to anvil

chain-configurations has a network file for anvil, local-dev.toml, and the libid-deploy tool that applies it. Download libid-deploy for your platform from its releases, and the network file:

curl -LO https://raw.githubusercontent.com/libid-org/chain-configurations/main/networks/local-dev.toml

Start anvil in its own terminal:

anvil

Then deploy:

libid-deploy apply --network local-dev.toml \
  --rpc-url http://127.0.0.1:8545 --yes --confirm-fresh-deploy

It deploys every libID contract with the real verifiers, owned by anvil’s first account. The addresses are fixed; see Addresses. Set the guides’ variables:

export RPC_URL=http://127.0.0.1:8545
export IDENTITY_REGISTRY=0x105b32e3daa9fda3572e89992c73b85a8a1065b3
export HANDLE_ESCROW=0xcd1fb9627c011cce322dabfcbcb4a09f66b26432
export PRIVATE_KEY=0x59c6995e998f97a5a0044966f0945389dc9e86dae88c7a8412f4603b6b78690d
export CAROL_KEY=0x7c852118294e51e653712a81e05800f419141751be58f605c371e15141b007a6

The keys are anvil’s public test keys. Never use them on a real network.

Nothing is bound on this stack, and a binding needs a real proof. So the lookups return null, and you can deploy contracts and send to the escrow, but not bind a handle or claim from it.

The guides’ test data

Where a guide shows output, it comes from the local-chain project. It sets RPC_URL, IDENTITY_REGISTRY, HANDLE_ESCROW, PRIVATE_KEY and CAROL_KEY as above, with its own registry and escrow addresses, and binds:

Handle	Id	Holder
GitHub octocat	583231	0x3C44CdDdB6a900fa2b585dd299e03d12FA4293BC
GitHub alice-dev	1001	0x70997970C51812dc3A010C7d01b50e0d17dc79C8
X alice_x	2244994945	0x70997970C51812dc3A010C7d01b50e0d17dc79C8

Each handle is also its holder’s published handle. PRIVATE_KEY’s address holds alice-dev and alice_x.

It also has ./bind.sh, which binds a handle without a proof:

./bind.sh github 777 carol $CAROL_KEY

The arguments are the platform, the id, the handle, and the key of the holder to bind it to.
