Solis settles in USDC on Ethereum. Converting dollars into USDC before a settlement (an on-ramp) and converting USDC back into dollars afterward (an off-ramp) happen entirely outside Solis, through third-party services you choose. Solis does not buy, sell, convert, hold, or transmit dollars or USDC for you, and does not partner with or endorse any provider.

To fund a settlement, the Payor needs USDC on Ethereum in a self-custody wallet. The usual path is to open an account with a regulated exchange or licensed on-ramp that supports USDC, complete its identity verification, buy USDC with dollars, and withdraw it to your own wallet address — selecting Ethereum (ERC-20) as the network. Two cautions apply: choose the Ethereum network (the wrong-network version can be lost), and withdraw to your self-custody wallet, not to an exchange account, because Solis needs a wallet that can sign. Keep a small amount of ETH for gas. Plan ahead — new-account verification and first-withdrawal holds or limits can take hours or days, and the funds must arrive before the payment deadline.

After a settlement closes, the Recipient receives the settlement in USDC and the Neutral receives any fee in USDC, in your wallets. To convert to dollars, the usual path is to open an account with a regulated exchange or licensed off-ramp that supports USDC on Ethereum, complete its identity verification, send your USDC from your wallet to the deposit address it provides (again selecting Ethereum/ERC-20), sell the USDC for dollars, and withdraw the dollars to your bank. You can also simply hold USDC in your wallet and off-ramp later. Sending USDC costs a small amount of ETH in gas.

Provider fees, exchange rates, and limits vary, so compare before you commit. Availability differs by country and, in the United States, by state; some providers do not serve all users. Verify the address and the network every time — on-ramp and off-ramp transfers are ordinary blockchain transactions and cannot be reversed. And receiving or converting settlement funds can have tax consequences; see Section 7 and consult your own advisor.

No. Solis provides the settlement workflow, the document, the escrow, and the on-chain record. It does not act as an exchange, money transmitter, or payment processor in these conversions, and it neither sees nor handles the dollar side of any on-ramp or off-ramp. Selecting a provider, meeting its requirements, and satisfying your own tax and legal obligations are your responsibility.
