Glass AI Node Registry Smart Contract

This repo contains the Glass AI Node Registry smart contract and its Foundry project setup. The registry lets inference-node operators register nodes with a payment vault, stake collateral, and publish per-model, per-token pricing.

---

What this contract does (high level)

A Node is a record with:

• operator address (can be rotated)
• payment vault address (must be a contract, non-zero)
• metadata URI (off-chain JSON / endpoint info)
• active flag (soft-delete / pausing)

Nodes must stake minStake of stakeToken on registration. When a node is removed, the full stake is returned to the current operator.

Each node can advertise multiple models, and each model can be priced in multiple ERC-20 payment tokens. Setting a model price to 0 for a given payment token removes that token-price; if the last token-price is removed, the model is removed from that node.

Repo layout

• src/GlassNodeRegistry.sol Main contract.
• script/GlassNodeRegistry.s.sol (or similar) Deployment script using env vars prefixed with REG_.
• test/ Foundry test suite.
• foundry.toml Foundry configuration (solc version, remappings, etc.).

---

Prerequisites

You’ll need Foundry installed:

curl -L https://foundry.paradigm.xyz | bash foundryup

OpenZeppelin contracts are pulled via remappings. If you’re missing deps:

forge install OpenZeppelin/openzeppelin-contracts --no-commit

Build

forge build

Test

forge test

Useful flags:

forge test -vvv forge test --match-test testRegisterNode forge test --gas-report

Deploy

Deployment is done through the script DeployRegistry.s.sol and requires three env vars, all prefixed with REG_:

• REG_ADMIN Address that receives DEFAULT_ADMIN_ROLE.
• REG_STAKE_TOKEN ERC-20 token address used for staking.
• REG_MIN_STAKE Minimum stake amount in token base units (e.g., for 18-decimals tokens, “100e18”).

Optional:

• REG_PRIVATE_KEY Broadcaster key if you want the script to auto-select it. If you omit this, pass --private-key or --mnemonic directly to forge.

Example: deploy to a live network

export REG_ADMIN=0xYourAdminAddress export REG_STAKE_TOKEN=0xYourStakeToken export REG_MIN_STAKE=100000000000000000000 export REG_PRIVATE_KEY=0xYOUR_PRIVATE_KEY

forge script script/GlassNodeRegistry.s.sol:GlassNodeRegistryDeployScript --rpc-url https://your.rpc.url --broadcast -vvv

The script will revert if any required env var is missing or zero.

Example: deploy to Anvil

Terminal 1:

anvil

Terminal 2 (Anvil’s default first key works):

export REG_ADMIN=0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 export REG_STAKE_TOKEN=0xYourMockOrDeployedToken export REG_MIN_STAKE=100e18 export REG_PRIVATE_KEY=0x59c6995e998f97a5a0044966f0945389dc9e86dae88c7a8412f4603b6b78690d

forge script script/GlassNodeRegistry.s.sol:GlassNodeRegistryDeployScript --rpc-url http://127.0.0.1:8545 --broadcast -vvv
