QuackAI has pushed a meaningful update to its Q402 payment infrastructure: batch payments are now live over Codex MCP. For developers building AI agents, on-chain tools, or payment-driven applications, this is the kind of update that quietly removes a wall you had stopped noticing was there.
One Command, Multiple Recipients, Zero Gas
Using either Codex CLI or any MCP-compatible client, developers can now dispatch USDC or USDT to multiple wallet addresses in a single operation with no gas held by the payer. The gas abstraction is handled natively by Q402's Paymaster layer, meaning teams no longer need to pre-fund wallets or manage gas accounts as a dependency in their payment flows.
This matters more than it sounds. Gas management has historically been one of the most underrated friction points in production crypto infrastructure, a persistent operational burden for any team running autonomous agents or scheduled settlement workflows at scale. Q402 removes it from the equation entirely.
Every batch settlement produces a Trust Receipt, a verifiable, on-chain proof of execution that both senders and recipients can audit independently. There are no ambiguous states, no "check back later." Settlement either happened or it didn't, and the receipt proves it.
The Codex MCP interface makes all of this accessible at the command line, which means teams can prototype, test, and ship payment logic without writing custom contract interaction code. Q402 handles the chain abstraction; developers focus on the workflow logic that actually matters to their product.
This is Q402 doing what it was designed to do: infrastructure that stays invisible until you need it, then works exactly as expected when you do. Batch payments over Codex MCP is a small surface update with outsized implications for anyone building at the intersection of AI agents and on-chain execution.
