Starknet's native token STRK is used for paying transaction fees on the Starknet Layer 2 network, which is built on Ethereum using ZK-rollup technology. Traders and developers swap into STRK when they need gas for on-chain activity on Starknet, or swap out when moving value back to other networks. Because STRK operates exclusively on its own network, confirming you are sending to the correct address format before initiating a swap is essential.
Before swapping STRK, verify that your receiving wallet or platform supports the Starknet network — STRK is listed on a single network, so there is no alternative chain to fall back on if the address is wrong. Starknet addresses follow a distinct format from Ethereum mainnet addresses, even though Starknet is Ethereum-based, so double-check that your destination address was generated specifically for Starknet. Confirmation times can vary depending on network conditions and ZK-proof generation, so allow some flexibility after sending. No memo or destination tag is required for STRK transfers. Zest shows the full rate and expected output before you confirm the swap, so review those details carefully on the final screen.
