Three builder profiles, three docs paths. Pick the one that matches what you’re shipping.

​
Payments and wallets

For PSPs, wallet teams, and payment applications moving USDT0. What success looks like
  • USDT0 flows settle on Stable with fees denominated in the same asset.
  • The right settlement primitive is selected for your use case: authorized transfers, HTTP-native payments, subscriptions, or invoices.
  • Funding, reconciliation, and compliance paths are documented end-to-end.
Next recommended

Integrate overview

Start at the map of connection, USDT0 behavior, and payment primitives.

ERC-3009

Implement Transfer With Authorization for on-chain settlement.

x402

Charge over HTTP without accounts or API keys.

Ecosystem

Find wallets, custody, ramps, and bridges already live on Stable.

​
Smart contracts and dApps

For Solidity and Vyper developers deploying applications on Stable’s EVM. What success looks like
  • Your contract is deployed with Foundry or Hardhat — the same workflow as Ethereum.
  • You’ve covered the three behaviors that differ from Ethereum: single-slot finality, USDT0 as the gas token, and USDT0’s dual native/ERC-20 role.
  • Tests cover allowance-based flows and solvency checks against real native balance.
Next recommended

Deploy a smart contract

Deploy, verify, and call a contract on testnet with Foundry.

USDT0 behavior

Port a contract to Stable without hitting dual-role gotchas.

Core mechanics

Read the fee model, JSON-RPC differences, and system modules end-to-end.

Differences from Ethereum

See what stays the same and what changes.

​
Infrastructure and node operators

For validator, RPC, and infrastructure teams running Stable nodes. What success looks like
  • A full or archive node is synced to the target network using a verified snapshot.
  • Monitoring and alerting watch block production and RPC health.
  • An upgrade path and operational runbook are documented.
Next recommended

Node operations overview

Start with node types and the operator mental model.

System requirements

Check hardware and software requirements by node type.

Installation

Install a node on your target platform step-by-step.

Monitoring

Wire metrics and alerting for block production and RPC health.

Quick start

Send a first transaction on testnet before picking a deeper path.

Core concepts

Learn the four behaviors that differ from Ethereum.

Production readiness

Validate an integration before shipping to mainnet.
