SpiritSwap

SpiritSwap is a non-custodial decentralized exchange and liquidity protocol on Fantom Opera: an automated market maker where swaps execute against onchain liquidity pools rather than an order book. Your wallet signs every transaction and output tokens land directly back in it, so no custodian holds the trade. The V2 architecture routes trades across available pool types through a master router, so a single swap can hop through more than one pool. Beyond swapping, the protocol supports liquidity provision, LP farming, and SPIRIT-based governance: locking SPIRIT produces inSPIRIT, which is used for gauge voting and directing protocol incentives. The published app lives at spiritswap.finance.

A SpiritSwap trade is a router path through one or more pools executed atomically in a single transaction. The quote shows expected output, price impact, slippage tolerance, and minimum received; minimum received is the output floor the transaction accepts if the pool moves before confirmation. Read minimum received, not just the headline quote. ERC-20 inputs need a separate approval transaction first, because the router cannot spend your tokens until you explicitly authorize it; the ERC-20 standard defines this allowance step, and it consumes its own gas. After you sign the swap, the contracts update pool reserves and send the output to your wallet once Opera confirms — finality is typically one to two seconds, but wallet prompts, RPC quality, and congestion stretch real completion time.

SpiritSwap is primarily a Fantom Opera protocol — mainnet chain ID 250, with FTM as the gas token — so your wallet must be on Opera, not Ethereum mainnet, before anything works. The Fantom Opera chain settings list chain ID 250 and FTM. Opera migrated toward Sonic in December 2024, but SpiritSwap's published app and contracts remain associated with Opera; SilverSwap on Sonic is a separate interface, not the same deployment. Pool availability varies by pair, and thin pools mean worse execution. SPIRIT is an ERC-20-compatible protocol token at 0x5cc61a78f164885776aa610fb0fe1257df78e59b.

SpiritSwap's swap cost has three parts: the pool fee taken from the input inside the AMM and distributed to liquidity providers; network gas paid in FTM, with the approval transaction and the swap each consuming gas separately; and price impact from your own trade size moving the pool. Gas fees are the network cost of executing a transaction or smart-contract call. Price impact grows with trade size relative to pool depth and appears in the quote before you sign. Small swaps in deep pools are dominated by gas; large swaps in shallow pools are dominated by impact. Slippage in finance is the difference between the quoted and executed price, so it is separate from the pool fee and gas.

SpiritSwap is non-custodial and publishes its contracts plus audit reports — V1, PeckShield V2, and Zokyo V2 are in the public repository — but an audit does not remove smart-contract risk. The remaining risks are smart-contract bugs, malicious lookalike tokens, careless approvals, and phishing. Granting an unlimited allowance gives a spender ongoing access to the approved tokens; that permission is separate from the swap itself. Before signing, verify the genuine app, the SPIRIT token contract at 0x5cc61a78f164885776aa610fb0fe1257df78e59b, and the router address at 0x16327e3fbdaca3bcf7e38f5af2599d2ddc33ae52. Deposited liquidity stays locked in protocol contracts until you withdraw it.

To swap on SpiritSwap, connect an EVM wallet configured for Fantom Opera and make sure it holds a little FTM for gas — no gas token, no transaction. Select the input token, output token, and amount, then read the route: expected output, price impact, slippage tolerance, and minimum received. If the input is an ERC-20, sign the approval first; its spender is the published router at 0x16327e3fbdaca3bcf7e38f5af2599d2ddc33ae52, and the approval is separate from the swap. Then sign the swap and wait for Opera confirmation; the output arrives directly in your wallet. If the quoted impact looks wrong for the trade size, split the order or reconsider the pool rather than raising slippage.

Wrong network: switch to Fantom Opera, chain ID 250, if the wallet is on Ethereum mainnet or Sonic. No gas: add FTM; transactions need FTM for fees. Stuck at approval: approval is a separate transaction, so an approved-but-unsigned swap has not traded; if approval is pending, speed it up or wait rather than re-approving. High price impact: reduce the amount, split the trade, or find a deeper pair instead of raising slippage. Reverted swap: refresh the quote and use a sane tolerance; if failures persist, switch RPC endpoints because an RPC hiccup can stop quotes loading.
