Overview

Ondo Global Markets (Ondo GM) tokenizes publicly-traded U.S. stocks and ETFs as ERC-20 assets, allowing investors outside the United States to mint, transfer, and redeem equity-backed tokens on Ethereum and soon other public blockchains. Each token represents direct exposure to the underlying asset, held with a regulated custodian through a licensed broker-dealer. To support integration across the ecosystem, Ondo GM offers a suite of APIs designed for infrastructure providers such as wallets, exchanges, and fintech applications. These APIs and Smart Contracts support:

Generating mint and redemption attestations to generate quotes that are fed to the Smart Contract layer.
Real-time and historical price data for each Ondo GM asset.
OHLC (Open, High, Low, Close) data to support charting, analytics, and historical views.
On chain mints and redemptions that handle the core logic for minting and redeeming Ondo GM tokens.

The API layer provides high-performance access to essential pricing, quote generation, token lifecycle, and token contract metadata. Whereas the Smart Contract layer provides the ability to mint and redeem (buy/sell) the tokenized asset. Here’s the typical flow for Ondo GM, using TSLAon as an example: Minting Process:

Primary Purchaser requests a mint attestation from Ondo GM API.
Primary Purchaser broadcasts transaction with the provided mint attestation signature along with a USD stablecoin (such as USDC) to the Smart Contract to atomically mint TSLAon to their whitelisted address.

Redeeming Process:

Primary Purchaser requests a redemption attestation from Ondo GM API.
Primary Purchaser broadcasts transaction with the provided redemption attestation signature along with TSLAon to the Smart Contract to atomically redeem TSLAon for a USD stablecoin (such as USDC) to their whitelisted address.
