ETH proves it. Base trades it.
ZARO originates on Ethereum — the canonical chain where the 1B cap is enforced. Base is the primary low-cost trading rail (Uniswap v3, ZARO/USDC). BNB Chain and Solana are maintained bridged representations — not promoted as primary trading venues. Total supply across all four chains never exceeds 1,000,000,000. Ever.
The one-billion rule
Total Supply = 1,000,000,000 ZARO (Ethereum, immutable) Ethereum : 1,000,000,000 (origin — all other chains draw from this) └─ locked in Base bridge : [variable] → minted on Base └─ locked in Wormhole : [variable] → minted on BNB Chain └─ locked in Wormhole : [variable] → minted on Solana └─ circulating on ETH : remainder SUM across all chains ≤ 1,000,000,000 ZARO. Always.
Every ZARO on Base, BNB Chain, or Solana exists only because an equal amount is simultaneously locked in bridge custody on Ethereum. Bridges cannot create new supply — they can only move it across chains.

All supply originates here. The 1,000,000,000 cap is enforced at this layer and is immutable. Contract ownership renounced — owner is the zero address.

Primary low-cost trading rail. Two pools: Uniswap v3 ZARO/USDC 0.01% (primary) and Aerodrome ZARO/WETH (fallback — LP burned to 0x000…dEaD permanently). Mint() is gated by `onlyBridge` — only the canonical L2StandardBridge predeploy can mint, and only against locked supply on Ethereum.

Trading status
BNB Chain and Solana are maintained bridged representations. They are not the primary recommended trading venues and are not promoted for active public trading. Contract addresses are provided for verification, continuity, and cross-chain infrastructure context. owner() = Wormhole Token Bridge contract (the protocol, not the team). Mint() is exclusively callable by the bridge with verified Guardian VAA messages.

Trading status
BNB Chain and Solana are maintained bridged representations. They are not the primary recommended trading venues and are not promoted for active public trading. Contract addresses are provided for verification, continuity, and cross-chain infrastructure context. Mint authority is a Wormhole PDA — `BCD75RNBHrJJpW4dXVagL5mPjzRLnVZq4YirJdjEYMV7` — a program-derived address with no private key.
Full security profile for SolanaBase (OP Stack): The canonical Coinbase L2 bridge. To move ZARO to Base, you deposit it into the L1StandardBridge on Ethereum; the matching L2StandardBridge on Base mints an equivalent amount of the OptimismMintableERC20 representation. To move it back, you burn on Base and the bridge releases the locked supply on Ethereum. mint() is gated by an onlyBridge modifier — no human can call it.
BNB Chain & Solana (Wormhole): Wormhole locks the source token in a guardian-verified escrow and mints a wrapped representation on the destination chain. Burning the wrapped token releases the locked supply. The mint authority on the destination is the Wormhole protocol itself — a smart contract on BNB Chain, a Program-Derived Address on Solana — neither of which has a private key.
The math: at any point in time, the sum of all bridged ZARO across Base + BNB Chain + Solana equals exactly the amount locked in the corresponding escrows on Ethereum. The 1B cap is enforced at the Ethereum layer and is permanent.
mint() is gated by onlyBridge — the canonical OP Stack L2StandardBridge is the only caller, and it only mints against locked supply on Ethereum.owner() is the Wormhole Token Bridge protocol contract, not a human wallet. It mints only against verified Guardian VAA messages that prove a matching lock on Ethereum.
