Filecoin

Before you send
Use a wallet that supports Filecoin mainnet.
Verify the deposit network on your order page matches your wallet.
Synthetix on Ethereum
Always match SNX on ERC-20 on Ethereum when you send or receive — wrong-network transfers may not be credited.
Receiving SNX
Your wallet must be on ERC-20 on Ethereum.
Allow a few minutes after the order shows sent before opening support.

Frequently asked questions
Do I need KYC to swap FIL to SNX?
No. SendSwap is a non-custodial instant exchange — no account, no ID checks, and no KYC for Filecoin to Synthetix swaps.
How long does FIL to SNX take?
Most swaps finish in 1–5 minutes. Timing depends on Filecoin mainnet and ERC-20 on Ethereum confirmations and current network load.
Is FIL to SNX non-custodial?
Yes. You send FIL from your wallet and receive SNX directly to the address you provide — SendSwap never holds your keys.
What if I send FIL on the wrong network?
Always match the network on your order page (Filecoin mainnet for deposits). Wrong-network sends may not be credited — read our swap safety guides before you send.
