Funding with USDC

USDC is a digital dollar, a token built to hold $1, and it is the money your fund trades in, on the Polygon network. Here is why a stable unit matters, how deposits work, and how money comes back out.

o Opusfund
The short version

You fund with USDC, a dollar that lives on-chain, on Polygon for low cost and speed. Money in is simple; money out is narrower by design It can only return to wallets you whitelisted.

A fund needs a unit of account that sits still while everything else moves. You cannot judge a bet’s result in a currency that swings harder than the bet. That is the entire case for USDC, and it takes one section to make. The rest is plumbing: how dollars get in, live, and leave.

01A dollar that lives on-chain

USDC is a stablecoin: a token designed to be worth one US dollar, issued against reserves held for that purpose, moving on blockchain rails. For your fund it behaves exactly like the dollar it represents, deposits are dollars, positions are priced in dollars, the memo’s wins and losses are dollars. No exposure to a volatile coin just to keep score. The two-line version: what is USDC?

02On Polygon, for a reason

Your fund’s USDC lives on Polygon The network Polymarket settles on, chosen for fees measured in fractions of a cent and confirmations in seconds. A fund placing many small, disciplined bets cannot pay big-network tolls on each one; on Polygon, the plumbing cost rounds toward zero, and trading itself is gasless on top.

03The way in

Funding is one transfer: send USDC on Polygon to your fund’s deposit address. From an exchange, that means choosing USDC, choosing the Polygon network, and pasting your address; from another wallet, a simple send. Two habits are worth keeping forever: match the network USDC sent on the wrong chain doesn’t arrive where you expect, and test with a small amount first, then send the rest once it lands. Details live in the FAQ: how do I fund my account?

04The way out, narrower by design

Withdrawals are yours any time, with no exit fee, but they can only travel to addresses you whitelisted in advance. That asymmetry is the point of the whole architecture: the CEO can deploy money into markets and bring it back; moving money out belongs to you alone. It trades your money. It can never take it.

⚠️

Your deposits sit in a non-custodial wallet only you control, so back up your keys and password somewhere safe. Nobody can recover them for you, and losing them can mean losing access to your money for good.

What to remember

  • USDC is a stable on-chain dollar One unit, one dollar.
  • It runs on Polygon for cheap, fast, gasless trading.
  • The way in is a straightforward deposit to your wallet.
  • The way out is deliberately narrow Only your whitelisted wallets.

Dollars in, dollars governed, dollars out, on your signature only.
