https://smoothsend.xyzAI Analysis
The skill documents legitimate integration with a commercial gasless transaction service (SmoothSend) for Aptos. The external API call to smoothsend.xyz is explicitly stated and necessary for the service's function. No credential harvesting, hidden instructions, or obfuscation is present, though it introduces a dependency on a third-party service.

A DeFi platform on Aptos removes gas fees for users staking tokens, allowing first-time users to stake without needing APT. The wallet adapter integration automatically sponsors transaction fees, reducing friction and increasing conversion.
An NFT marketplace sponsors gas fees for minting and trading NFTs, enabling users to create or purchase NFTs without holding APT. This lowers entry barriers for new collectors and boosts marketplace activity.
A remittance app uses the Script Composer to let users send USDC gaslessly, with the fee deducted from the transferred amount. Migrant workers can send stablecoins home without needing to hold or acquire APT.
A mobile wallet integrates the SmoothSend transaction submitter to offer a 'sponsored' mode, where the dApp covers gas for token swaps or small payments. This enables a seamless mobile experience where users never see gas fees.
dApp operators purchase credit packs from SmoothSend to cover user gas fees. Revenue comes from charging users indirectly via subscription fees, higher transaction fees, or monetizing increased engagement.
dApps offer a limited number of free sponsored transactions per user per day, then charge for additional sponsored transactions or revert to user-paid gas. This converts casual users into paying customers.
A dApp charges users a flat monthly fee for unlimited sponsored transactions via SmoothSend. The dApp passes a portion of that fee to cover SmoothSend credits, creating predictable revenue.
💬 Integration Tip
For a basic gasless setup, just install the SDK and pass a SmoothSendTransactionSubmitter to the AptosWalletAdapterProvider's dappConfig — no other code changes needed.
