Even after all these years of building, crypto liquidity feels fragmented. We broke down how 1inch Aqua aims to fix this with Sasha in Abu Dhabi.

Key takeaways

  • 1inch began as a hackathon project at ETHNewYork, when its founders built an aggregator to find the best swap rate across DEXs.
  • It now serves users through the 1inch dApp and mobile wallet, and businesses through 1inch Business APIs used by wallets like MetaMask, Trust Wallet and Phantom.
  • Intent-based swaps remove gas fees for users and pull liquidity from DEXs, centralized exchanges and private pools through resolvers.
  • 1inch Aqua is a shared liquidity protocol that lets the same funds back several strategies at once while staying in the user's wallet.
  • Aqua launched as a developer release on EVM chains, with Solana support planned for the following year.
  • Sasha says 1inch only deploys to new chains once real DeFi activity exists, and names Base, Solana, BNB Chain and Ethereum as the strongest.

A DeFi gateway built by traders for traders

Recorded on day three of Solana Breakpoint 2025, this Hodl Up episode features Sasha, head of business development at 1inch. Sasha moved from banking into crypto in 2016 and has spent almost four years at 1inch. Her crypto start came over lunch, when a banking client mentioned an ICO. "I said, 'I understood nothing, but I agree with you.'"

The conversation covers how 1inch works, why it is courting institutions, the trade-offs of that shift, its new Aqua protocol, its approach to Solana and other chains, and where she sees 1inch in five years.

How 1inch works

The Skyscanner of swaps

Sasha recalled when swapping crypto meant texting a friend for cash, then paying steep fees to early exchanges and processors. Uniswap introduced permissionless swaps at market rates, but checking every DEX was tedious. "They didn't want to spend time checking the best rates on different DEXs, so they created an aggregator." She compared it to searching flights on Skyscanner.

From B2C to B2B

Wallets such as MetaMask, Trust Wallet and Phantom wanted the same routing under the hood, so 1inch launched 1inch Business with APIs including the Swap API and the Portfolio API. Consumers can use the 1inch mobile wallet or dApp. "We're an entry point to DeFi, a DeFi gateway."

The table below summarizes how 1inch's swap technology has evolved, based on Sasha's account.

Serving institutions without losing DeFi

Meeting TradFi on its terms

Sasha sees memecoins, NFTs and GameFi as simple entry points that grew the user base. She pointed to token launches by the presidents of Argentina and the US, which she said had pros and cons but onboarded millions of users in one move. By her estimate, crypto awareness has grown from about 1% of people when she started to around 14%.

That growth brought institutions. "When you talk to institutions, nobody asks you what your TVL is. They ask whether you're compliant, how stable your service is and what your SLAs are." The rebrand reflects that shift, though the unicorn remains. "Otherwise we'll never reach the first billion users."

Custody and self-custody side by side

Sasha separated decentralization from privacy and said both custodial and self-custody options are needed. Her ideal: any app offers a choice between full self-custody and a custodial route. Users who start with custody often move into DeFi once they feel comfortable.

1inch Aqua and shared liquidity

Sasha said fragmented liquidity is one of DeFi's core problems. A user with $100,000 must split it across staking, farming and lending, and moving funds means risk and lost yield. Aqua revives ideas from Mooniswap, a project the dev team started around 2018.

With Aqua, funds stay in the user's wallet and can back several strategies at once without being locked. Market makers and projects can build DEXs on top of Aqua, which checks whether a wallet's balance covers each trade. It launched as a developer release. "You make your capital efficient by letting the Aqua protocol use your liquidity to execute certain strategies."

Solana, EVM chains and what comes next

Sasha said 1inch deployed on Solana because the market is there, though much of its current activity is not yet advanced DeFi. 1inch offers a native Solana implementation and cross-chain swaps, and plans to bring Aqua to Solana to deepen liquidity. She sees Solana as an efficient payments chain, and believes payments plus Aqua could spark another DeFi summer.

For 2026, she pointed to Aqua on Solana, SwapVM improvements and continued hackathon support through Colosseum and ETHGlobal. "The rule at 1inch is deliver first, then communicate." Her five-year vision is banks offering self-custody and DeFi options powered by 1inch, with RWAs tradable through its partners.
