In the Metalayer of Caldera, the solver is one of the most critical roles. They are responsible for automatically finding the best execution path after the user submits their intention. Unlike traditional cross-chain bridges that rely on a single path, Caldera aggregates multiple solvers such as Across, Relay, Eco, etc., forming a decentralized bidding market.
The advantage of this mechanism lies in multiple guarantees: when one solver experiences delays or insufficient liquidity, other solvers immediately take over, ensuring that the cross-chain process does not interrupt. Users no longer need to worry about the "bridge getting stuck"; instead, they can enjoy an optimal experience in terms of speed and cost. For developers, they can directly call the unified interface of Metalayer without having to maintain multiple cross-chain services themselves.
Furthermore, the solver ecosystem can incentivize more third-party participation. Any team can join as a solver, providing liquidity and execution services while profiting through transaction fees. This makes Metalayer not only a technical network but also an open economic network.
As the number of solvers increases, the cross-chain experience will improve, and prices will decrease. This is what makes Caldera special: it is not a single bridge, but a "solver network." This design makes Metalayer more like the "router" of the internet, automatically finding the fastest channels to securely deliver data and assets.
