We leverage EIP-2612 Permit signatures which allow you to authorize token transfers by simply signing a message - completely free and without any blockchain transaction. Once you sign, our relayer submits the transaction on your behalf, paying the gas fees. The small service fee is deducted directly from the tokens you're sending.

Your security is our top priority. We use battle-tested, audited smart contracts deployed on each supported network. Your funds remain in your wallet until the exact moment of transfer - we never have custody of your assets. All permit signatures are time-limited and can only be used for the specific transfer you authorized.

Our fee structure: 2% for transfers up to 100 tokens, 1% for 100-1000, 0.5% for 1000-10000, and 0.25% for larger amounts. Minimum fee is 1 token. Ethereum Mainnet has premium pricing (3%/2%/1%/0.5%) due to higher gas costs. Subscribe to save up to 50%!

We support any ERC-20 token that implements the EIP-2612 Permit standard. This includes major stablecoins like USDC and USDT, as well as many DeFi tokens. Not all tokens support this feature - our interface will notify you if a token isn't compatible.

No! That's the whole point of our service. You can send ERC-20 tokens even if your wallet has zero native tokens for gas. We handle all the gas fees for you, making crypto transfers accessible to everyone.

Transfers are typically confirmed within 10-30 seconds, depending on network congestion. Once your permit signature is received, we prioritize fast transaction submission to ensure your tokens arrive quickly.

We currently support Cronos, BNB Chain, Polygon, Arbitrum, Base, Avalanche, and Fantom. More networks are being added regularly. Check our supported networks section for the most up-to-date list.

Subscriptions give you discounted fees on all transfers. Basic plan offers 10% off, Pro gives 25% off, and Enterprise provides 50% discount. If you make frequent transfers, a subscription can save you significant amounts over time.

We implement multiple layers of security: OpenZeppelin's ReentrancyGuard prevents reentrancy attacks, Pausable allows emergency stops, all inputs are validated, nonce tracking prevents replay attacks, each wallet has a $50,000 daily limit, and rate limiting protects against DDoS. Our smart contracts are based on battle-tested EIP-2612 standard used by Uniswap, OpenSea and other major protocols.

No. Your permit signature is specifically tied to: (1) our verified contract address as the only valid spender, (2) a time deadline after which it expires, (3) a single-use nonce that prevents replay. Even if someone intercepts your signature, they cannot redirect funds - the transfer destination is cryptographically locked in the signed message.
