everPay

everPay is a payment protocol built on Arweave following the storage consensus paradigm: Arweave serves only as the data availability layer, raw transactions are batched on-chain for storage, computation and state are handled by an execution-layer server, detectors independently recompute with the same algorithm and compare results, and withdrawals are released by a group of detectors acting as watchmen through multi-signature approval. Product functions cover deposit, transfer, withdrawal, and swap, with wallet interaction supported across Ethereum, Arweave, Moonbeam, Conflux, and other chains.

It targets the cost and throughput limits of on-chain payments: by moving consensus from negotiation among chain nodes to off-chain recomputation plus data attestation, transaction costs fall to roughly one dollar per million transactions. Its execution layer also powers instant settlement of atomic orders for decentralized exchanges in the ecosystem, and public storage nodes use it as a gas-free payment rail, letting users pay for Arweave permanent storage with any supported token.
