Networks
GenLayer operates as two layers: the GenLayer RPC handles intelligent contract operations (gen_* methods), while the GenLayer Chain is the underlying Arbitrum Orbit L2 that handles standard Ethereum operations (eth_* methods). The GenLayer RPC also passes through supported eth_* calls to the underlying chain, so you can use either endpoint for standard wallet operations.
For the full RPC reference, see GenLayer Node API.
For transfers and staking, connect to the GenLayer Chain RPC. Intelligent-contract methods such as gen_call require a GenLayer node RPC; the Conduit chain RPC does not provide them. Use a Phase 2-compatible GenLayer node endpoint for SDK intelligent-contract operations.
Testnet Bradbury
Production-like testnet with real AI/LLM workloads.
| Setting | Value |
|---|---|
| GenLayer RPC | Use the Phase 2 node RPC published in the release announcement, or your own qualified node |
| GenLayer Chain RPC | https://rpc.testnet-chain.genlayer.com |
| Chain ID | 4221 |
| Currency | GEN |
| Validator / staking UI | stakegen.com (opens in a new tab) |
| Chain Explorer | scan.testnet-chain.genlayer.com (opens in a new tab) |
| Faucet | testnet-faucet.genlayer.foundation (opens in a new tab) |
Bradbury Phase 2 reuses chain ID 4221. Verify block zero has hash 0x17d89764d4f4f963158fc4c5e8f2cb670c2837740b35f37081c12860c3df97e4, and the AddressManager is 0x3F71AE080BD6270A91dBcc7960d88797828538E0. An old RPC can return the right chain ID but lead to a different deployment. If a public domain returns a different genesis, stop and have its routing corrected.
The GenLayer Chain WebSocket is wss://rpc.testnet-chain.genlayer.com and requires an API key. Create a key at app.conduit.xyz/rpc-keys (opens in a new tab) and configure it as GENLAYERNODE_ROLLUP_GENLAYERCHAINRPCKEY in the node environment (or the .env next to docker-compose.yaml). Never add it to URLs or config.yaml. Resolve Staking and ConsensusMain through the AddressManager instead of treating their initial addresses as permanent network identity.
Public domains above are the intended release endpoints. Check their readiness and the faucet's target network before transferring funds; do not assume old balances or registrations carry over.
Studionet
Hosted development environment — no local setup required.
| Setting | Value |
|---|---|
| GenLayer RPC | https://studio.genlayer.com/api |
| Chain ID | 61999 |
| Currency | GEN |
| Explorer | explorer-studio.genlayer.com (opens in a new tab) |
| Faucet | Built-in — use the 💧 button in the account selector |
Studio development preview
Release-candidate environment for testing the next Studio and consensus stack before it is promoted to Studionet. State and availability are not guaranteed across deployments.
| Setting | Value |
|---|---|
| Studio web app | studio-dev.genlayer.com (opens in a new tab) |
| Canonical GenLayer RPC | https://studio-dev.genlayer.com/api |
| Chain ID | 61997 |
| Currency | GEN |
| Explorer | explorer-studio-dev.genlayer.com (opens in a new tab) |
| Faucet | Built-in — use the 💧 button in the account selector |
Use the matching release-candidate SDK or CLI and its explicit studioDevnet / studio-dev network preset. Do not relabel the stable studionet preset: the environments have different chain IDs and deployments. If studio-next.genlayer.com is enabled as a browser alias for this same environment, integrations should still use the canonical studio-dev.genlayer.com/api RPC.
Localnet
Local development with full control. Requires GenLayer Studio or GLSim.
| Setting | Value |
|---|---|
| GenLayer RPC | http://localhost:4000/api |
| Chain ID | 61127 |
| Currency | GEN |
| Explorer | Bundled with Studio at http://localhost:8080 |
| Faucet | Built-in — use the 💧 button in the account selector |
GenLayer Chain (L2)
The underlying Arbitrum Orbit L2 for Bradbury Phase 2. You typically don't need to interact with this directly — the GenLayer RPC passes through supported eth_* calls. But if you need direct L2 access (e.g., token transfers, contract debugging at the EVM level), you can add this chain to your wallet.
| Setting | Value |
|---|---|
| RPC | https://rpc.testnet-chain.genlayer.com |
| Chain ID | 4221 |
| Currency | GEN |
| Explorer | scan.testnet-chain.genlayer.com (opens in a new tab) |
Network Comparison
| Bradbury | Studionet | Studio dev | Localnet | |
|---|---|---|---|---|
| Purpose | Production-like testing | Hosted stable dev | Next-stack RC validation | Local dev |
| Setup | None | None | Matching RC tooling | Docker or GLSim |
| Persistence | Persistent | Temporary | Temporary; resets expected | Local only |
| LLM execution | Real models | Real models | Real models | Configurable |
| Faucet | Available (opens in a new tab) | Built-in | Built-in | Built-in |
Recommended Flow
- Start on Studionet — zero setup, open studio.genlayer.com (opens in a new tab)
- Use Studio dev only for release-candidate validation — open studio-dev.genlayer.com (opens in a new tab) with the matching RC tooling
- Move to Localnet — when you need full control and fast iteration
- Deploy to Bradbury — when ready for production-like testing with real AI workloads
