Learn more about zkLink

What is zkLink?

zkLink is a ZK-powered aggregation layer that unifies liquidity from multiple L2s and L1s, enabling cross-rollup spot and derivatives trading without bridges.

How to get zkLink RPC endpoint?

Create a free account at Chainstack and log in to the console. Click Add node, pick zkLink (mainnet or testnet), and deploy a dedicated node in seconds. When the node shows as running, go to Access & credentials to copy your HTTPS and WebSocket RPC endpoints.

How to run a zkLink node?

Deploy a Global Node on Chainstack to integrate zkLink proofs without standing up circuits. Choose a Dedicated Node for heavy cross-rollup settlement. Self-hosting entails compiling Starkware libs, running provers, and handling liquidity snapshots.

What is zkLink RPC API?

zkLink exposes a RESTful API for proof aggregation alongside EVM JSON-RPC for settlement. Endpoints like zkLink_getProof verify cross-roll-up deposits, while eth_call queries unified liquidity pools. The abstraction hides individual L2 differences behind one gateway.

How much does it cost to run a zkLink RPC?

zkLink’s proof aggregation and EVM settlement require strong CPUs, costing US $150-300 / month. Maintaining circuits and liquidity snapshots adds to that. Using an RPC provider such as Chainstack minimizes expense for most teams.

Is zkLink RPC free?

zkLink provides free aggregation endpoints, though proof bursts can choke them. A free Chainstack plan includes 3 million reliable zkLink requests.

How to setup a zkLink RPC?

Copy the zkLink endpoint in Chainstack. Point your SDK’s provider or wallet RPC field to that URL to interact with the aggregation layer.

Notes for zkLink API

zkLink RPC nodes conform to the JSON-RPC interface, giving developers a way to interact with the zkLink chain remotely. By using established tools like ethers.js and web3.py, building scalable apps on zkLink becomes fast and straightforward.
