Base Sepolia
The corridor is the real testnet cNGN and Circle’s USDC. cNGN has no EIP-2612 permit, so a wallet approves Permit2 once with a normal transaction. USDC supports permit. Circle’s faucet issues test USDC on Base Sepolia. Owner and treasury are the deployer until the multisig exists.

Solana devnet
The program is Jupiter’s order-engine, vendored unchanged except for its program id and deployed under Panofx’s id. The test cNGN and USDC are Panofx’s own mints, because the issuers’ devnet tokens cannot be minted for tests. Two corridors run on devnet, cNGN/USDC and cNGN/USDT, and each pair’s fees are charged in its own dollar token.
Chain ids follow the old Solana token list: 101 mainnet-beta, 102 testnet, 103 devnet, and 104 and above for
local validators. The node checks the RPC’s genesis hash against the id it was given.
House resolvers
Two house nodes,node-alpha at 40 bps and node-bravo at 60 bps, quote from the hosted relay so that the
corridor is never empty. They price off the relay’s oracle band. Your node competes with them on price, and
on reliability when prices tie.
