Network and access

AGORA runs on Robinhood Chain, an Arbitrum Orbit L2 where gas is paid in ETH. Any EIP-1193 browser wallet is supported, and installed wallets are discovered over EIP-6963.

Most wallets do not ship with Robinhood Chain configured. On connection AGORA requests a network switch and, if the chain is unknown, requests that it be added. On the wrong chain, reads return nothing and writes fail.

Some endpoints require a Sign-In With Ethereum signature, which proves control of an address and authorises no transfer. Two use it: opening a draw sequence, which costs the operator a transaction, and requesting a mint voucher for a purchase.
