How to Win the Multi-Chain Future

We dig into the best yield opportunities on four cross-chain protocols.
Feb 2, 20234 min read

The future is multi-chain.

Whether you believe it will happen with multiple L1s like Ethereum, Cosmos and Solana, or a roll-up centric future, there’s an opportunity to earn money by fueling these cross-chain swaps.

The main way to do this is by providing liquidity to any of the top bridge aggregators – like Hop, Synapse, and Across. In return for doing so, you’ll earn a trading fee for your service.

Better yet - our prediction was right — most cross-chain bridges today have launched a token with a yield farming program, providing a nice yield boost for all LPs.

Interested in capitalizing on this opportunity?

This article highlights some of the best yields from cross-chain bridges on the market right now.

➰ Hop Protocol

  • Networks: Ethereum, Arbitrum, Optimism, Gnosis Chain, Polygon
  • Yields: 8 - 12% APY

The first major bridge is Hop.

Built on a rollup token bridge, Hop Exchange allows users to transfer assets cross-chain between major Ethereum Layer 2s and sidechains.

The protocol leverages market makers known as Bonders, who earn fees for fueling the liquidity behind these swaps. The bridge currently holders around $66M in value locked and has facilitated billions of dollars in transfers.

After launching the HOP token, the protocol implemented a liquidity mining program, issuing 2.2M HOP every month on ETH, USDC, DAI, and USDT liquidity pools. The allocation of the tokens is determined by the volume of each bridge, changeable by governance.

Interestingly, Hop currently offers a few pools with multi-asset rewards. The first is the SNX bridge which is incentivized with both HOP and OP, offering a 28% annualized yield for LPs.

The other two notable pools are the DAI and USDT Gnosis pools, where LPs of these stablecoin pools earn both HOP and GNO as part of their rewards program.

🧠 Synapse

  • Networks: Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Canto, Avalanche
  • Yields: 5 - 22% APY

Synapse (SYN) is described as a cross-chain messaging protocol.

The Synapse Bridge enables users to swap between a range of L1 and L2 assets using an AMM. Unlike Hop Protocol, Synapse expands beyond Ethereum and its encompassing chains and enables swaps between alternative Layer 1s like Canto, Avalanche, and Harmony, in addition to the prominent Ethereum L2s like Arbitrum and Optimism.

That said, similar to Hop, Synapse also features the SYN token which is distributed via a substantial yield farming program across the majority of pools.

As you can see below, there’s a handful of lucrative opportunities to capitalize on, with yields going as high as 22% for the hottest new L1 on the scene: Canto.

🌉 Across

  • Networks: Ethereum, Arbitrum, Optimism, Gnosis Chain, Polygon
  • Assets: ETH, USDC, USDT, DAI, WBTC
  • Yields: 4.5 - 17% APY

Across Protocol has become a fair competitor on the cross-chain landscape, recently crossing over $1.3B in total value transferred.

Built by the team at UMA Protocol, the bridge works by offering incentives for LPs to provide short-term loans to users on the other chain, which are repaid after two hours from a liquidity pool on L1.

After launching the token in November, the protocol now offers a couple yield farming opportunities for the ACX token. Across’s yield farming program stands out as it gives LPs a rewards multiplier based on the amount of time the user has provided the liquidity.

Users can reach the max APY listed below by providing liquidity on the protocol for more than 100 days.

🌟 StarGate

  • Networks: Ethereum, Avalanche, BNB Chain, Polygon, Arbitrum, Optimism, Metis
  • Yields: 3-10% APY

The final bridge we’ll discuss is Stargate, built on Layer 0’s omnichain technology.

The protocol currently has $381M in TVL with its token, STG, trading at an $83M market cap and $600M FDV. Similar to the above bridges, the protocol taps into its native token in order to boost the yields for prospective LPs.

Most of the pools on the platform include these STG rewards – going to upwards of 10% APY on the Metis USDT pool and 9.9% APY on the FRAX Optimism Pool.

There’s plenty of opportunity in the cryptoverse to earn high yielding APYs by providing liquidity for cross-chain swaps.

The recent surge in activity on Cosmos chains like Canto and Ethereum Layer 2s allows LPs to capitalize on these value flows.

People are bridging between chains, all the time.

This guide serves as the basis to start earning.

You can win the multi-chain future by providing the picks and shovels (read: liquidity) for these value flows. Take a look at the landscape and see if one of these is the right opp for you!
