Summary

Adds zkTanenbaum Testnet (57057) as a standard EVM-compatible chain definition.

Network metadata:

  • RPC: https://rpc-zk.tanenbaum.io
  • Explorer: https://explorer-zk.tanenbaum.io
  • Native currency: TSYS
  • Block time: 2_000 ms
  • Multicall3: 0xcA11bde05977b3631167028862bE2a173976CA11, deployed in block 477
  • Chain metadata PR: Add zkTanenbaum Testnet ethereum-lists/chains#8391

zkTanenbaum is a Syscoin zkSYS edge testnet running ZKsync OS v31. It uses standard EVM-style JSON-RPC/transactions for developer tooling, while the state transition is proven through the Airbender RISC-V proving stack.

Validation

  • npx @biomejs/biome@2.2.4 check src/chains/definitions/zkTanenbaum.ts src/chains/index.ts .changeset/zk-tanenbaum-chain.md
  • IDE lint check on touched files

Note: full repository checks were not run locally because this shell is on Node v23.2.0, while the repo currently declares node >=24.5.

Add zkTanenbaum as a standard EVM-compatible Syscoin testnet chain definition.
