Skip to main contentDeposits & Funding
Since Onyx is self-custodial, you do not deposit funds “into” Onyx. Instead, you fund your own Web3 wallet (e.g., MetaMask, Rabby, Phantom).
Supported Assets
Onyx operates with USDC on the Polygon network, as this is the standard for the major prediction markets we aggregate.
How to Fund
- Purchase USDC: Buy USDC on a centralized exchange (Coinbase, Binance, Kraken).
- Withdraw to Polygon: Withdraw your USDC to your wallet address on the Polygon network.
- Bridge: Alternatively, use a bridge like Portal or Hop Protocol to move assets from Ethereum mainnet or other chains to Polygon.
