‍4. The Service — Software Orchestration
‍ONCHAIN provides a software orchestration platform that composes independent third-party services into a unified user experience for the purpose of allowing you to purchase digital assets. ONCHAIN itself does not provide financial services. Specifically:
‍
‍4.1 ONCHAIN does not custody user funds.
‍At no point in any transaction does ONCHAIN hold, custody, or have access to your fiat currency or your digital assets. ONCHAIN does not control any private keys associated with your wallet or with any intermediate addresses used in transaction execution.
‍
‍4.2 ONCHAIN does not perform KYC or payment processing.
‍All KYC verification, AML screening, fiat payment processing, foreign exchange conversion, and stablecoin or asset delivery is performed by the Payment Provider under its own regulatory licenses and authorizations. Your relationship with the Payment Provider for these services is governed by the Payment Provider's own terms and privacy policy.
‍
‍4.3 ONCHAIN does not execute trades.
‍ONCHAIN does not operate an order book, matching engine, or market-making system. For DEX-Traded Tokens (Path 2), on-chain swap execution is performed by the Routing Protocol, a decentralized smart-contract system that operates autonomously based on the parameters you authorize at the order confirmation step. ONCHAIN has no discretion over execution timing, price, or routing decisions made by the Routing Protocol.
‍
‍4.4 The Service operates in two paths.
‍The Service routes your transaction through one of two paths, determined automatically based on the asset you have requested:
- Path 1 — Inventory Asset purchases. If the asset you have requested is an Inventory Asset, the Payment Provider delivers the asset directly from its custodial inventory to your Recipient Wallet. Path 1 transactions do not involve the Routing Protocol or the Clearance Protocol.
- Path 2 — DEX-Traded Token purchases. If the asset you have requested is a DEX-Traded Token, ONCHAIN runs the Clearance Protocol to screen the token. If the token passes Clearance, the Payment Provider delivers USDC to a deposit address generated by the Routing Protocol. The Routing Protocol then executes a swap from USDC to the requested token and delivers the resulting token to your Recipient Wallet.
‍
‍4.5 Your authorization.
‍You explicitly authorize ONCHAIN to orchestrate the transaction flow on your behalf based on the parameters you confirm at the order confirmation step, including the spend amount, requested asset, fee structure, and Recipient Wallet. ONCHAIN acts solely as your agent for the purpose of coordinating the Service. You retain control of and responsibility for your transaction instructions at all times.
‍
‍5. Token Clearance Protocol
‍For Path 2 transactions (DEX-Traded Tokens), ONCHAIN applies an automated Clearance Protocol designed to screen tokens for known categories of token-design risk before any transaction is initiated. The Clearance Protocol evaluates tokens against parameters including, without limitation:
- Contract security: closed source contracts, mintable supply, hidden owner privileges, self-destruct functions, and similar contract-level risks.
- Trading security: honeypot characteristics, transfer-pausability, buy/sell tax thresholds, and similar trading-level risks.Malicious indicators: known phishing addresses, sanctioned addresses, fake KYC, money-laundering associations, and similar reputational risks.
- Liquidity thresholds: minimum liquidity depth on relevant DEX pools. Tokens that fail Clearance are not eligible for purchase through Path 2 and may be offered an alternative purchase path (such as the chain native token via Path 1).

‍Clearance is not investment advice.
‍The Clearance Protocol screens for known categories of technical risk only. A token passing the Clearance Protocol is not an endorsement, recommendation, or guarantee by ONCHAIN regarding the token's value, legitimacy, regulatory status, future performance, or suitability for any purpose. You are solely responsible for evaluating the merits and risks of any digital asset you purchase. See Section 11 (Risks and Disclaimers) below.

‍6. Account Registration and Authentication
‍To use certain features of the Service, you may be required to authenticate via the Authentication Provider. By authenticating, you agree to the Authentication Provider's terms and privacy policy. You are responsible for maintaining the confidentiality of your authentication credentials and for all activities that occur under your account. You agree to notify us immediately of any unauthorized access to your account.

‍7. Recipient Wallet Designation
‍You designate the Recipient Wallet at the order confirmation step. You are solely responsible for ensuring that:
- The Recipient Wallet address you designate is correct and corresponds to a wallet that you control on the destination blockchain.
- The Recipient Wallet is compatible with the asset you are purchasing and the blockchain on which it will be delivered.
- The Recipient Wallet is not a smart contract or other address that cannot properly receive the requested asset.

‍Transactions are irreversible.
‍Once you confirm your order and the transaction is initiated, the transaction cannot be reversed or cancelled. If you designate an incorrect Recipient Wallet, or a Recipient Wallet on the wrong blockchain, or a Recipient Wallet you do not control, the assets delivered to that address may be permanently unrecoverable. ONCHAIN, the Payment Provider, and the Routing Protocol bear no liability for losses resulting from incorrect Recipient Wallet designation.

‍8. Fees
‍Your use of the Service may involve the following categories of fees, which are disclosed to you at the order confirmation step before you authorize the transaction:Payment Provider fees: fees charged by the Payment Provider for KYC, payment processing, foreign exchange conversion, and asset delivery. These are independent fees set by the Payment Provider.Network gas fees: blockchain transaction fees required to execute on-chain operations. These vary based on network conditions and are not controlled by ONCHAIN.Routing Protocol fees: fees charged by the Routing Protocol for executing on-chain swaps on Path 2 transactions, including any slippage between the quoted price and the executed price.ONCHAIN fee: a software service fee charged by ONCHAIN for orchestrating the transaction. The ONCHAIN fee is disclosed in the fee breakdown at the order confirmation step.All fees are non-refundable except as expressly stated in these Terms or required by applicable law.

‍9. Quotes and Best-Effort Output
‍The output amount shown to you at the quote stage is a best-effort estimate based on market conditions at the moment of quote. For Path 2 transactions, the actual amount of the target token delivered to your Recipient Wallet is determined at the moment of on-chain execution and may differ from the quoted estimate. The Service displays a minimum-received floor at the order confirmation step; if the actual delivered amount would fall below the minimum-received floor due to market conditions, the Routing Protocol's slippage protection will cause the transaction to revert and trigger the refund flow described in Section 10.

‍10. Refunds and Failed Transactions
‍Refund handling depends on the stage at which a transaction fails:If the Payment Provider does not confirm payment, no funds are transferred and no refund is necessary.If the Payment Provider confirms payment but the Routing Protocol's swap execution fails (Path 2), the Routing Protocol returns the stablecoin to the Payment Provider via the refund destination configured at quote time. The Payment Provider is then responsible for issuing the corresponding fiat refund to you. Refund timing and policy are determined by the Payment Provider's terms.If the Payment Provider confirms payment and delivers the requested asset to your Recipient Wallet (Path 1), the transaction is complete and is not refundable except to the extent required by the Payment Provider's terms or applicable law.
‍
‍11. Risks and Disclaimers
11.1 No investment advice.
‍ONCHAIN does not provide investment, financial, tax, or legal advice. Nothing on the Service constitutes a recommendation or endorsement to purchase any digital asset or to engage in any transaction. You are solely responsible for your transaction decisions.
‍
‍11.2 Risks of digital assets.
‍Digital assets are highly volatile, may lose value rapidly or completely, and may be subject to regulatory, technical, market, and counterparty risks. Risks include but are not limited to: price volatility; loss of liquidity; smart contract bugs or exploits; bridge or routing protocol failures; blockchain network failures or congestion; loss of private keys; phishing, fraud, or theft; regulatory changes that may affect the legality of holding or transacting in digital assets; and total loss of value. You assume all such risks.
‍
‍11.3 Third-party services.
‍The Service relies on independent third-party services (including the Payment Provider, the Routing Protocol, the Authentication Provider, and others). ONCHAIN does not control these third-party services and does not guarantee their availability, accuracy, or performance. Disruptions, outages, or failures of these third-party services may affect your ability to use the Service or complete transactions.
