AU.RO RPCMulti-chain RPC, one key

17 production chains behind a single gateway — JSON-RPC and REST, metered in Compute Units, with caching and failover built in.

One key, every chain

A single API key opens Bitcoin, Ethereum, BSC, Polygon, Avalanche, XRP, TRON, Cosmos, NEAR, Aptos, Cardano and more — same host, same header.

ethers / viem / web3 work by swapping the URL. Migrating from Infura, Alchemy or QuickNode is a one-line diff.

Usage is billed in Compute Units with public per-method weights. Cached responses are served with an explicit X-Cache header.

bitcoind JSON-RPC, ogmios for Cardano, CometBFT for Cosmos, REST for TRON / Aptos — no lowest-common-denominator wrappers.
