Hyperspace A1 is EVM-compatible. Any tool built for Ethereum works here. Same RPC, same transaction format, same addresses.

EVM-compatible sovereign L1

A1 runs the Ethereum Virtual Machine as a sovereign Layer 1 with its own consensus. Not an L2, not a fork — an independent chain that speaks the same language as Ethereum.

Solidity contracts — deploy any .sol contract. OpenZeppelin, Uniswap, Aave — all work.
Same addresses — 0x-prefixed, 20-byte Ethereum addresses. Your keys work.
Same transactions — EIP-1559, EIP-2930, legacy types supported.
Same RPC — eth_, net_, web3_ namespaces. Drop-in replacement.
Same tooling — MetaMask, Hardhat, Foundry, Remix, ethers.js, viem, web3.py.

What’s different from Ethereum:

Consensus — NarwhalTusk DAG BFT. Sub-second finality.
Routing — stake-secured Hydra DHT replaces gossip.
Agent opcodes — 25 additional EVM opcodes for ML inference, training receipts, MCP tool calls, reputation, and streaming payments.
Streaming payments — hspace_pay RPC for sub-cent agent-to-agent payment channels. Shipped v1.3.0 on 8 Apr 2026.
Proof-carrying transactions — EIP-2718 type 0x13 txs that embed their own Verkle witnesses for stateless execution.
Chain ID — 808080.

Agent-native RPC methods (hspace_*)

The Hyperspace chain extends the Ethereum JSON-RPC surface with an hspace_ namespace for agent-to-agent streaming payments. Shipped in v1.3.0 on 8 Apr 2026 and live on the public testnet.

open a payment channel

curl -X POST -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "hspace_openPaymentChannel",
    "params": [{
      "from":    "0xAliceAgent...",
      "to":      "0xDataProviderAgent...",
      "deposit": "1000000",
      "token":   "HSPACE"
    }]
  }' \
  https://rpc.a1.hyper.space/

stream a sub-cent payment (hspace_pay)

curl -X POST -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 2,
    "method": "hspace_pay",
    "params": [{
      "channelId": "0xabc...",
      "amount":    "250",

install + run

npm i -g @hyperspace/cli

# Health check every subsystem (keys, chaindata, bootnodes, RPC)
hyperspace doctor

# Tail node logs in real time
hyperspace logs --follow

# Open a payment channel from the CLI
hyperspace pay open --to 0xBobAgent... --deposit 1000000

# Stream a payment through an open channel
hyperspace pay stream --channel 0xabc... --amount 250 --memo "chunk-47"

# Settle and close
hyperspace pay close --channel 0xabc...

Proof of Intelligence

Validators on Hyperspace do not just forge blocks. They prove useful cognitive work through Proof of Intelligence (PoI) checkpoints, and earn ongoing rewards tied to measurable agent output. The full protocol specification and validator onboarding funnel live on the proofofintelligence.hyper.space subdomain.

Independently verify the network

Query any public bootnode. No trust required — the data is on-chain.
