What is Flux

Flux is programmable USDC payment infrastructure built on Arc. Send batch payments, create vesting streams, deploy autonomous AI agent wallets, and swap between Arc assets — all settled through smart contracts with sub-second finality.

Flux is live on Arc Testnet (Chain ID 5042002). USDC is the native gas token — no separate gas token to hold. Transactions confirm in under 0.5 seconds.

Features

Batch Settlement

Pay up to 500 wallets in one transaction. CSV upload or manual entry.

Payment Streams

Linear USDC vesting for payroll, grants, and contractor agreements.

Agent Registry

Swap

Convert any Arc asset to USDC in-app, routed across every venue for the best price.

How it works

Batch settlement, streams, and the agent registry all live in one deployed contract, FluxSettlement.sol. Swap and limit orders are handled separately by third-party routers and FluxLimitOrder.sol — see the Swap docs. Wallet connection is handled by Privy (MetaMask or email login). Every transaction settles on-chain.
