Payments on Stable

Stable is built around payments. USDT0 is the native asset and the gas token, so settlement and fees share one balance. Single-slot finality means a transfer clears in under a second. ERC-3009, EIP-7702, and x402 are native primitives, not workarounds — you can settle with a signature, pull from a delegated account, or charge per HTTP request without running a billing stack.

What you can build

• P2P transfers — native USDT0 sends with 21k gas and sub-second finality.
• Subscriptions — pull-based recurring billing with EIP-7702 delegation.
• Invoice settlement — ERC-3009 transferWithAuthorization with deterministic nonces for exact reconciliation.
• Pay-per-call APIs — x402 middleware for per-request USDT0 payments; no API keys, no sign-ups.
• Zero-gas UX — application-sponsored transactions via the Gas Waiver service.
• Cross-chain USDT0 — LayerZero OFT bridging from Ethereum and other networks.

How Stable differs

• One asset for everything: the sender doesn't hold a separate gas token.
• Native ERC-3009: USDT0 implements transferWithAuthorization directly, so payments settle with a signature and no approve step.
• Deterministic finality: a block is final the moment it's committed. No confirmation waits.
• Native x402: the facilitator pays no gas through the Gas Waiver, so per-request settlement costs stay below a cent.

Start here

• Send your first USDT0 — Native and ERC-20 transfers on the same balance.
• Zero gas transactions — Transfer USDT0 with the fee covered by a Gas Waiver.
• Learn P2P payments — Build a wallet + send + receive + history app from scratch.
• Build a pay-per-call API — Price HTTP endpoints per request with x402.
• Stable SDK — Use the typed client for transfer, bridge, and swap in a few lines.

Payment primitives

• ERC-3009 — Transfer With Authorization: the settlement standard behind invoices and x402.
• x402 (HTTP-native payments) — Server responds 402, client signs ERC-3009, facilitator settles on-chain.
