Identity

• Public name: R0AR AURUM Chain Testnet · gas AURM · future mainnet R0AR AURUM Chain Mainnet
• Testnet EVM chainId: 19909399
• Gas / native token: AURM (18 decimals)
• Mainnet chainId (later): 199093

Consensus

Aura + GRANDPA proof-of-authority. Alice and Bob are the initial authorities (local-origin). Participant nodes sync the chain and may earn C2 work rewards by submitting heartbeats — a reward layer, not a consensus change.

Economics (public testnet v1)

• C2 epoch pool: 0.1 AURM shared by heartbeats (~1k AURM/mo per public node @4 peers)
• Trusted nodes: 10× share weight (operator-elevated)
• Fee burn: 0.5% of each fee
• Emission halvings ~every 6 months; no hard cap (floor 1 wei)

SDKs seeded on testnet

Gnosis Safe, delegate.xyz, ERC-4337, EAS, OZ AccessManager, ERC-4626/7540, T-REX mock (not Tokeny production KYC — that is a later phase), ERC-8004 experimental, Multicall3, Permit2, WAURM, CREATE2 factories. Address JSON ships in the developer starter registry.
