x402 is to AI payments what ERC-20 was to tokens, a standard waiting for adoption.
@Mantle_Official is the first chain to adopt this standard. They partnered with
$SANTA, who are already proving use-cases.
@santavirtuals is by
@questflow which is a Google Cloud certified partner.
Mantleβs modular stack happens to line up almost perfectly with x402βs needs:
β’ 15 MB/s throughput (EigenDA): handles high-frequency micro-transactions between agents.
β’ ZK-proofed since September: verifiable, privacy-preserving compute.
β’ Gas β $0.002 / tx: makes sub-$1 transactions economically viable again.
β’ x402 AI Gateway: gives AI agents multichain access directly through Mantle.
Beyond that,
$MNT roadmap converges three macro themes:
β’ Banking rails via
@UR_global:
45 country IBAN access, debit cards, 5β8% stablecoin APY,
@ethena yield integration, 500K downloads, $100M deposits.
β’ Tokenized RWAs, through Tokenization-as-a-Service with full compliance stack.
Partnership with
@worldlibertyfi onboarded $2.6 B USD1 stablecoin liquidity.
β’ Institutional DeFi layer - mETH (LST), fBTC (wrapped BTC), MI4 ($400M tokenized index), $730M stablecoins on-network.
This stack gives Mantle something no other L2 currently has: a path to monetize agentic activity itself.
The x402 gateway is now live on Mantle.
Builders and creators can connect to the x402 protocol via the facilitator and start experimenting building (faster) today.
Together with
@questflow, we're bringing x402 to everyone, everything and everywhere within our ecosystem.
