Our transition to Phase II is complete. With the latest contracts up and the community governance process underway, AirSwap aims to be the world’s best decentralized peer-to-peer trading system. Staking to vote starts today on Codefi Activate.

AirSwap is a natively global project. From the initial whitepaper through the token launch, both its core contributors and launch participants have been distributed around the world. The token launch itself was among 9,447 people from 135 countries.

One of AirSwap’s earliest goals was to operate as an effective open organization with a transparent structure and process. …


AirSwap OTC enables trading without third-party escrows, deposits, or trading fees. Synthetix, iExec, Tellor, Band Protocol, and more top ecosystem projects have endorsed AirSwap OTC — find out how your project too can benefit from trustless trading.

Decentralized systems like AirSwap enable peer-to-peer asset transfer without relying on third-parties to broker trades or custody assets. Over-the-counter (OTC) transactions, however, are still often facilitated via chat room based escrow services that can turn out to be malicious. Stories of escrow failures and scams have led to fear and frustration within our community.

Trustless OTC Trading

Last August, we launched AirSwap OTC, providing a trustless…


Add your token, set your price. Delegates enable on-chain, non-custodial, and trustless limit order functionality on the AirSwap network through an intuitive interface. Add liquidity today at https://instant.airswap.io/delegates.

AirSwap provides trustless peer-to-peer trading between counterparties, without the need to give up custody, pay trading fees, or sign up for an account. The design resembles RFQ, where automated makers provide prices via API to everyday traders. While this functionality works seamlessly and has allowed the network to grow, adding tokens and setting prices on the network has been limited to those able to run automated makers.

The AirSwap team traveled to Japan to share our work with the wider Ethereum community. We were excited to meet all of the teams and individuals that came out for the event and thank everyone who attended our talks.

From October 8th to 11th, the Ethereum community came together to collaborate and ideate around how best we can push decentralized protocols, tools, and culture to the masses. Ten of the AirSwap team arrived at the conference with five members leading talks and workshops.

AirSwap software engineers Alice Henshaw, Sam Walker, and Ethan Wessel dove deep into technical sessions, while software…


Our team discovered a critical vulnerability in a new AirSwap smart contract. Read on to understand the steps we’ve taken to prevent the vulnerability from being exploited, and to determine whether you need to take immediate action.

Updated Oct. 3 with technical details below.

On September 12th, our internal security review processes identified a potential exploit in a newly released mainnet AirSwap smart contract. The vulnerability would allow an attacker, under certain conditions, to perform a swap without requiring a signature from a counterparty. The affected code was present in the AirSwap system for under 24 hours, and only affects…


For the next two weeks, Gitcoin and Ethereal Summit are running the Ethereal Blocks virtual hackathon. The AirSwap team has posted bounties to use two new building blocks: the new AirSwap Trader widget and AirSwap Protocols.

Decentralized trade starts with an atomic swap. Today, we’re publishing new protocols including on-chain peer discovery and delegation, enabling even more powerful applications and integrations throughout decentralized finance.

Traders on AirSwap continue to use the original Swap contract deployed years ago. It does one job well: to swap tokens and ether. Immutable like any smart contract, it will continue to support applications that fit.

Setting a course

Since then, we’ve seen both needs and opportunities to expand its capabilities and deploy new protocol elements as smart contracts. …
