# Our Swap Addresses When creating a swap on a specific chain, you need to specify a receiver. This receiver MUST be one of our Swap Addresses below. For example, if the user wants to make a Swap from Vechain to Ethereum on testnet, during the smart contract call to create the swap on Vechain, set the receiver as the Vechain Testnet Swap Address. **IMPORTANT:** This is not the same as the `targetReceiver` in the API call to our server. The `targetReceiver` should always be the **user's** account on the destination chain. ### Our Swap Addresses **Mainnet** * Ethereum: 0x1bde1Bae878131B919ce8316619C8409f2624E5f * VeChain: 0x1bde1Bae878131B919ce8316619C8409f2624E5f * BNB Smart Chain: 0x1bde1Bae878131B919ce8316619C8409f2624E5f * Polygon: 0x1bde1Bae878131B919ce8316619C8409f2624E5f * Base: 0x1bde1Bae878131B919ce8316619C8409f2624E5f * Polygon: 0x1bde1Bae878131B919ce8316619C8409f2624E5f **Testnet** * Ethereum (Sepolia): 0xB25928E30F0751Ff7cCfd8592D75C734FDeC3B38 * VeChain: 0x4917A44C40C2b59c4DD96ffa422C438dAF27Da09 * BNB Smart Chain: 0xB25928E30F0751Ff7cCfd8592D75C734FDeC3B38 * Polygon (Mumbai): 0xB25928E30F0751Ff7cCfd8592D75C734FDeC3B38 * Base (Sepolia): 0xB25928E30F0751Ff7cCfd8592D75C734FDeC3B38 * Optimism (Sepolia): 0xB25928E30F0751Ff7cCfd8592D75C734FDeC3B38 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.safeswap.io/builders/api-integration-guide/our-swap-addresses.md?ask= ``` The question should be specific, self-contained, and written in natural language.
