CallPut vs SOFA.org: chains, options and safety (2026)

CallPut is the more focused choice for options traders who want synthetic exposure to stocks, ETFs, BTC or ETH. It runs on Base and says users can trade around the clock, including when the referenced equity market is closed. That access has limits: spreads may widen or trading may be restricted during closures, corporate actions or volatility. Its stock and ETF contracts are synthetic, not shares or broker-listed options.

SOFA.org takes a broader, multi-chain approach. It lists deployments on Ethereum, Arbitrum, BNB Chain and Polygon, and offers options alongside structured products and Automator, which is aimed at options trading and yield generation. Its exact mechanics are not public. Choose CallPut for its stated synthetic stock and crypto markets; choose SOFA.org if chain choice and a wider product mix matter more.

Neither project publishes clear fee rates. CallPut describes its fees as competitive and low-cost but gives no figures. Its trade pricing factors in time to expiry, liquidity, spreads, fees and risk adjustments, and Base network gas also applies. The full cost is meant to appear in the trading interface before confirmation.

SOFA.org does not publish fees for premiums, protocol charges, settlement or Automator performance. Users should also account for the gas fee on their chosen chain. That makes a direct cost comparison impossible from published rates. Before committing funds on either platform, inspect the displayed product price and applicable gas cost. Do not assume a lower TVL, more chains or a particular product type means a cheaper trade.

CallPut lists no audits, and it does not name a team, security review or bug bounty. Treat its smart-contract security as unverified. The protocol also identifies risks involving markets, liquidity, reference data, oracles, volatility and regulation. Its non-custodial design keeps funds in a user’s wallet until they are used in the protocol, but liquidity-pool depositors face risks in stressed markets. CallPut is new and has a small TVL, so its track record is limited.

SOFA.org has two audits listed, but the auditors, dates, scope and findings are not public. The audit count is useful context, not a guarantee of safety. Its non-custodial settlement does not remove smart-contract, oracle, settlement or product-price risks. Options can lose the full premium, and neither platform should be treated as risk-free.

CallPut reports TVL of about $181,607, compared with about $1.47 million for SOFA.org. Both are small by the standards of DeFi options, and TVL alone does not reveal the depth of a specific market or the size of trade it can support. CallPut’s stated $1 starting size may suit smaller trades, but that does not make its pools suitable for larger orders. Spreads may widen, and liquidity can vary.

SOFA.org’s higher TVL does not guarantee low slippage or ample liquidity in every product or chain. Its TVL has also been volatile, with a reported seven-day increase of 76.3%. Check the specific product and chain before trading, and do not infer execution quality from headline TVL alone.

Choose CallPut if you specifically want synthetic options tied to stocks or ETFs alongside BTC and ETH, and you are comfortable using a young Base-only protocol whose audits are not listed. Its premium-based leverage means option buyers’ losses are capped at the premium paid, though liquidity providers face different risks. The synthetic contracts do not provide share ownership, dividends or voting rights.

Choose SOFA.org if access across four chains and a mix of options and structured products are more important to you. It has two audits listed and a nonprofit, open-source framing, but audit details and fees are not public, and its products can lose the full premium. For either choice, check local rules and product terms before trading, and only risk funds you can afford to lose.
