11-Chain Nanopayment Anchor
Circle Gateway Nanopayments ships on 11 mainnet chains. Hive's multichain anchor coordinator submits the same Aurora-Lattice-signed Merkle root to all 11 in parallel — Base, Ethereum, Arbitrum, Avalanche, HyperEVM, Optimism, Polygon, Sei, Sonic, Unichain, World Chain. A nanopayment is verifiable from any chain a counterparty can reach.
How it plugs in.
multichain_anchor.js
// One root. 11 chains. Aurora-Lattice signed. import { prepareMultichainAnchor, GATEWAY_NANOPAYMENT_CHAINS } from '@thehiveryiq/circle-core'; const root = merkleRoot(nanopayments); const sig = auroraLattice.sign(root); const txs = prepareMultichainAnchor({ root, sig, chains: GATEWAY_NANOPAYMENT_CHAINS, // all 11 }); // Submit in parallel. Receipt-bound across the full Gateway footprint. await Promise.all(txs.map(submit));
What Circle gets.
- Receipt anchors match the full footprint Circle just shipped — 11 chains, no gaps.
- Counterparty on any chain can verify a nanopayment from any other chain.
- Aurora-Lattice root signing — regulator-defensible across jurisdictions.
- Differentiator: nobody else anchors a single signed root across all 11 Gateway chains.
Ready when Circle is.
