Connext presents the opportunity to bet on a multi-chain, multi-layer world through a capital infrastructure play
At its core, Connext is an L2<>L2 / L1 bridging solution, allowing users to move capital between chains / layers in a trustless and efficient manner
With a strong team and a very competitive product, Connext will be able to capitalize on winner-take-all economics and, through its SDK-based business model, will become the backbone to dApp cross-chain operations. Overall, Connext’s value lies in its future abstraction — it is ‘behind the scenes’ financial plumbing
Finally, Connext presents great opportunities for value add as well as multiple avenues to exit
Connext is an interoperability protocol for interacting between L1s and L2s. Without introducing any new trust assumptions or external validators, Connext’s NXTP (the protocol technology) lets users swap assets across L1s and L2s in an efficient and timely manner.
Note that the emphasis is on the word ‘swap’ and not ‘port’ or ‘migrate’. The current version of Connext cannot be used to pass arbitrary event data between chains; therefore, one cannot use the protocol to migrate a token from Chain A to B
Albeit, users will not become frustrated at this inability, as swapping USDC on BSC to USDC on Optimism is basically the same as migrating, except that it is cheaper and faster than using migrating-based bridges
NXTP is a lightweight, simple contract that uses a locking pattern, a network of off-chain routers that participate in pricing auctions and pass ‘calldata’ between chains, and a user-side SDK that finds routes and prompts on-chain transactions
Ecosystem Players:
Users
Interact with a front end that is powered by NXTP. Best example right now is xPollinate
Undergo the transaction process (discussed below) to fulfill the need of swapping one asset from one chain for it on another chain / rollup
Routers
dApps
Transaction Process:
The process can be broken down into three phases:
Route action: the user broadcasts a message signaling their desired use of a specific bridging route. Routers respond with sealed bids containing commitments to fulfilling the transaction within a certain time and price range
Preparation of transaction: once a bidder is selected, the user submits a transaction containing the router’s signed bid to the contract on the user’s side. This consequently locks up their funds on the user chain. The router detects an event (sealed chosen bid message) and the contract locks up the assets on their side. This lock up is incorporative of their fees
Fulfillment: the user’s side will then receive a confirmation message of funds locked and it will send a signed message for a relayer to claim. This relayer (typically another router) will submit the transaction and receive a submission fee
Note that transactions can be cancelled unilaterally by the person owed funds on that chain (router for sending chain, user for receiving chain) prior to expiry

There are three ways to approach interoperability between chains:
Narrow Competition
Hop Protocol
A locally verified mechanism for sending tokens across rollups. Hop leverages existing arbitrary messaging bridges (“AMBs”) to send funds between chains, with a bonder (liquidity provider) fronting the capital to make the process fast. To incentivize rebalancing, the protocol also utilizes AMMs on both sides to swap between the “canonical” asset for a chain and hTokens, a representative asset used by the bonder
Since the proof of transfer is passed between chains using an AMB, Hop doesn’t need users to run off-chain code like Connext
Presents the following tradeoffs:
Hop is less economically secure than Connext. It depends on AMBs, which means that if chains don’t have them, they need to be created. This introduces new security risks. Hop’s design also cuts corners like optimistic rollups’ seven day exit periods for settlement
Hop is less capital efficient. It requires both entry and exit liquidity given its AMM model on both sender and receiver chains. In contrast, Connext LPs only need exit liquidity and incur no liquidity lockup, “achieving 10x+ better capital usage”
Limitations to bonding. Bonders must pay gas costs based on Ethereum mainnet. Connext can have transactions go directly from L2 to L2 without touching the base layer
Bonders are exposed to MEV and transaction submission races, according to the Connext team. Transactions cannot be front run on Connext as the users negotiate route and pricing off-chain
Synapse
Synapse conducts integral blockchain activities such as asset transfers, swaps, and generalized messaging with cross-chain functionality. The Synapse network is secured by cross-chain multi-party computation (“MPC”) validators operating with threshold signature schemes (“TSS”). The network is leaderless and maintains security by each validator running the same process upon receiving on-chain events. Once two-thirds of all validators have collectively signed the same transaction using their own individual key, the network achieves consensus and issues a transaction to the destination chain
Currently, validators are selected based on community governance and consensus. Upon reaching a certain project milestone, validators on the Synapse Network will have to stake $SYN to secure the network
Presents the following tradeoffs:
While it can enable fast and efficient swaps, it introduces significant new trust primitives that can lead to increased security risk. With a whole new group of validators (currently selected by the community, which can be worrying) and game theory, Synapse adds complexity, whereas Connext bypasses it. Both can do the same thing when it comes to swaps, except that right now, Synapse can use its protocol ($SYN) to increase yields for pool deposits, creating increased liquidity in the short term
When compared to Connext, certain swapping routes are relatively complicated and involve several more swaps than needed. This may introduce issues pertaining to higher fees in the long run, as well as increased risks along the way
Wide Competition
Ren
Not necessarily trustless
Lacks scalable way to integrate with other chains / layers given its security configurations
Great for porting over assets, not necessarily moving value fast
Cosmos
Works when all chains run on Tendermint / are a parachain
Expensive in terms of time and fees. Like Ren, the focus isn’t on moving value fast and efficiently
THORChain
Positioned more as an L1<>L1 exchange that seeks to establish permissionless swapping between L1 native assets, using RUNE as a medium of exchange as well as for security collateral. There is a future where THORChain releases pools for rollup swaps, however, this is not within the project’s current core focus
Leads to increased security risk, whereas Connext inherits the security of the base chains it works on top off
If THORChain’s decentralized swapping capabilities prove successful and scalable, this could be a threat to Connext’s offerings pertaining to L1<>L1 swaps
Bridges
Examples: Optimistic bridge, Near Rainbow bridge, Avalanche bridge
These lack the time and cost benefits that Connext offers, and in many ways, are the worst choices presented to users. They are crucial in the infrastructure they provide, but their use should be minimized to significant capital movements (in order to set up swapping pools and liquidity on the other side) as well as batch-settlement capital flows
#1 If one underwrites the thesis of a multi-chain, multi-layer world, Connext offers a ‘project-neutral’ way to bet on it. At its essence, it is an infrastructure play and wins no matter which L1s and L2s prevail.
Competition in the L1 and L2 space can intensify, developing commodity-like market traits
The cross-chain bridging space, on the other hand, is indicative of winner-take-all economics. With L1s or L2s, it makes sense for a user / dApp to use multiple ones (as they have different offerings); however, for a bridge aggregator technology, it makes more sense to use the best one that covers all ecosystems, rather than multiple ones
Location within the value chain can emerge as a value sap: Connext is a group of capital superhighways and generates revenue through tolls
#2 Value lies in the SDK. Connext is a B2B protocol that will behave like abstracted infrastructure within the logic of dApps. It strategically makes sense for dApps to have inter-chain functionality built into their ops as dApps will want to maintain users on their site for the whole cross-chain process, otherwise they risk losing the user to another competing dApp. Therefore, Connext’s capital plumbing will be of value.
This is not a long-term prediction; rather, dApp integration with cross-chain liquidity infrastructure is becoming a priority. Several takeaways from ETH Lisbon have discussed dApp teams needing to focus on solving for cross-chain capabilities.
#3 Sizable TAM. The value of transactions going through bridges will be in the billions, and eventually trillions, assuming the multi-chain, multi-layer world develops. With some tweak-able conservative assumptions, Fee TAM is in the low billion single digits:
#4 Great team with deep sub-sector expertise
Known amongst the right circles for their leadership in cross-chain bridging
Rich dev experience suitable for the complexity of the team’s goal
Past track record highlights ability to execute. Specifically, recent releases have been well received, and in circumstances of bugs, they were corrected and updated in a timely manner
#5 Opportunities for value add combined with multiple exit strategies
Leverage network as integration opportunities for the Connext team
Assist with team hiring and community growth. Currently, the community is somewhat small as evidenced by experience on Discord. Achieving a community like Index Coop, where several BD strategies can be led by members, could formulate part of the go-to-market
Offer expertise on token economics design
Value add is complemented by multiple paths to exit:
M&A: Can be acquired by another bridging solution, wallet provider (i.e. Metamask), or infrastructure company
Token (much more likely): Can go liquid via a token drop, with lockup expiry probably lying between 1–4 years
#1 Growth of L2 ecosystems
Once more dApps onboard and bring transaction-intensive ops to L2s, ecosystem growth will really hit full tilt
Progress with development at Arbitrum, Optimism, and other chains / rollups point to the imminence of this catalyst
#2 High gas environment on Ethereum
#3 Connext’s integrations with other frontends and applications
#4 Progress with liquidity expansion
#1 Smart contract risk
#2 Execution risk
#3 PMF risk
#4 Aggregators win out over protocols
