Relay alternatives for swaps. For swaps across chains.
Checked October 27, 2026.
Why wallets running swaps look past Relay
Users deposit into Relay's depository on the origin chain. A solver fills the order on the destination chain with its own capital and is repaid from the depository once Relay verifies the fill.
Best for: EVM and Solana wallets that want published low swap fees, a mature SDK and a long list of chains. What wallets running swaps run into:
- No Lightning or Zcash.
- Quotes are re-priced at fill, with no stated window in which the price holds.
- Bitcoin swaps wait for a confirmation, two for large amounts.
The alternatives
1. Flashnet
Deposits, swaps and withdrawals API
Best for: Wallets that want native swaps across Bitcoin, Lightning, Solana, Tron and EVM chains, long-tail tokens included, each funded by a plain transfer, with their own fee on every order.
Choose Flashnet if your wallet swaps into or out of Lightning or Zcash, wants a quoted price that holds for 2 minutes, or wants Bitcoin credited before confirmation.
2. NEAR Intents
Intent-based cross-chain protocol with competing market makers
Best for: Wallets that want market makers competing on every swap across a very wide set of chains.
3. deBridge
Intent-based cross-chain swap protocol
Best for: EVM and Solana wallets that want a rate guaranteed at signing and hooks that act after the swap.
4. LI.FI
Cross-chain bridge and DEX aggregator
Best for: Wallets that want one SDK in front of dozens of bridges, DEXs and solvers, with a ready-made widget.
